Sanchez-Pulido, L., D. Devos, et al. (2002). "BRICHOS:
a conserved domain in proteins associated with dementia, respiratory distress
and cancer." Trends Biochem Sci27(7): 329-32.
A novel domain (the BRICHOS domain) of approximately 100
amino acids has been identified in several previously unrelated proteins that
are linked to major diseases. These include BRI(2), which is related to familial
British and Danish dementia (FBD and FDD); Chondromodulin-I (ChM-I), related to
chondrosarcoma; CA11, related to stomach cancer; and surfactant protein C
(SP-C), related to respiratory distress syndrome (RDS). In several of these, the
conserved BRICHOS domain is located in the propeptide region that is removed
after proteolytic processing. Experimental data suggest that the role of this
domain could be related to the complex post-translational processing of these
proteins.

"Sporadic and familial cerebral amyloid angiopathies." Brain Pathol12(3):
343-57.
Cerebral amyloid angiopathy (CAA) is the term used to
describe deposition of amyloid in the walls of arteries, arterioles and, less
often, capillaries and veins of the central nervous system. CAAs are an
important cause of cerebral hemorrhage and may also result in ischemic lesions
and dementia. A number of amyloid proteins are known to cause CAA. The most
common sporadic CAA, caused by A beta deposition, is associated with aging and
is a common feature of Alzheimer disease (AD). CAA occurs in several familial
conditions, including hereditary cerebral hemorrhage with amyloidosis of
Icelandic type caused by deposition of mutant cystatin C, hereditary cerebral
hemorrhage with amyloidosis Dutch type and familial AD with deposition of either
A beta variants or wild-type A beta, the transthyretin-related meningo-vascular
amyloidoses, gelsolin as well as familial prion disease-related CAAs and the
recently described BRI2 gene-related CAAs in familial British dementia and
familial Danish dementia. This review focuses on the morphological, biochemical,
and genetic aspects as well as the clinical significance of CAAs with special
emphasis on the BRI2 gene-related cerebrovascular amyloidoses. We also discuss
data relevant to the pathomechanism of the different forms of CAA with an
emphasis on the most common A beta-related types.

"Enduring increased risk of developing depression and mania in patients with
dementia." J Neurol Neurosurg Psychiatry73(1): 40-4.
OBJECTIVE: To investigate the time relation between dementia
and major affective disorders (major depression and mania). METHODS: Register
linkage study of the Danish Hospital Register and the Danish Psychiatric Central
Research Register, to establish study cohorts of patients with dementia and
control groups (osteoarthritis or diabetes) on first discharge from hospital.
Follow up of cohorts was for up to 21 years. Hazard of death was allowed for by
the use of competing risks models. RESULTS: Patients with dementia had an
increased risk of being admitted to hospital for major depression or mania
during the course of the illness. The incidence remained elevated throughout the
rest of the patient's life. CONCLUSIONS: Patients with dementia have an
increased risk of developing depression or mania. Proper treatment of affective
disorders in patients with dementia is important in reducing suffering and
costs.

"[Diagnosis and treatment of Lewy body dementia]." Ugeskr Laeger164(18):
2383-6.
Dementia with Lewy bodies (DLB) has recently gained
recognition as a separate disease. Lewy bodies are pathoanatomical inclusion
bodies in the CNS. They are well known as part of Parkinson's disease where they
are present mainly in the substantia nigra, and they are also found in large
numbers in the neocortex. It is still an unanswered question why Lewy bodies are
formed, but their appearance is connected with cellular degeneration of unknown
aetiology. Neuropathological investigations of dementia populations show that
DLB accounts for 12-36%, which places it as the second most frequent dementia
disease after Alzheimer's disease (AD) with a frequency close to that of
vascular dementia. This article reviews the development of the term DLB and
describes the clinical characteristics, including the neuropsychological symptom
profile, which can contribute to the diagnostic discrimination between DLB and
AD. Furthermore, relevant treatment possibilities are discussed.

processing of familial British dementia-associated BRI variants: evidence for
enhanced intracellular accumulation of amyloidogenic peptides." J Biol Chem277(3): 1872-7.
Different mutations in the BRI(2) gene cause rare
neurodegenerative conditions, termed familial British dementia (FBD) and
familial Danish dementia (FDD). The mutant genes encode BRI-L and BRI-D, the
precursors of fibrillogenic ABri and ADan peptides, respectively. We previously
reported that furin processes both BRI-L and its wild type counterpart, BRI,
resulting in the secretion of C-terminal peptides; elevated levels of peptides
were generated from BRI-L. In the present study, we show that inducible
expression of alpha1-antitrypsin Portland, a furin inhibitor, inhibits the
endoproteolysis of BRI and BRI-L in a dose-dependent manner. Moreover,
comparison of the activities of several proprotein convertases reveals that
furin is most efficient in endoproteolysis of BRI and BRI-L; PACE4, PC6A, PC6B,
and LPC show much lower activities. Interestingly, LPC also exhibits enhanced
cleavage of BRI-L compared with BRI. Finally, we demonstrate that BRI-D is also
processed by furin and, like BRI-L, the cleavage of BRI-D is more efficient than
that of BRI. Interestingly, while the ABri peptide is detected both
intracellularly and in the medium, the ADan peptide accumulates predominantly in
intracellular compartments. We propose that intracellular accumulation of
amyloidogenic ADan or ABri peptides results in the neuronal damage leading to
FDD and FBD, respectively.

"Familial Danish dementia: a novel form of cerebral amyloidosis associated with
deposition of both amyloid-Dan and amyloid-beta." J Neuropathol Exp Neurol61(3): 254-67.
Familial Danish dementia (FDD) is pathologically
characterized by widespread cerebral amyloid angiopathy (CAA), parenchymal
protein deposits, and neurofibrillary degeneration. FDD is associated with a
mutation of the BRI2 gene located on chromosome 13. In FDD there is a decamer
duplication, which abolishes the normal stop codon, resulting in an extended
precursor protein and the release of an amyloidogenic fragment, ADan. The aim of
this study was to describe the major neuropathological changes in FDD and to
assess the distribution of ADan lesions, neurofibrillary pathology, glial, and
microglial response using conventional techniques, immunohistochemistry,
confocal microscopy, and immunoelectron microscopy. We showed that ADan is
widely distributed in the central nervous system (CNS) in the leptomeninges,
blood vessels, and parenchyma. A predominance of parenchymal pre-amyloid (non-fibrillary)
lesions was found. Abeta was also present in a proportion of both vascular and
parenchymal lesions. There was severe neurofibrillary pathology, and tau
immunoblotting revealed a triplet electrophoretic migration pattern comparable
with PHF-tau. FDD is a novel form of CNS amyloidosis with extensive
neurofibrillary degeneration occurring with parenchymal, predominantly pre-amyloid
rather than amyloid, deposition. These findings support the notion that
parenchymal amyloid fibril formation is not a prerequisite for the development
of neurofibrillary tangles. The significance of concurrent ADan and Abeta
deposition in FDD is under further investigation.

cytokines, antibodies to Chlamydia pneumoniae and age-associated diseases in
Danish centenarians: is there a link?" Scand J Infect Dis34(7):
493-9.
Plasma levels of tumour necrosis factor (TNF)-alpha levels
increase with age. High levels are associated with dementia and atherosclerosis
in centenarians. Chlamydia pneumoniae induces the production of proinflammatory
cytokines and has been related to the pathogeneses of Alzheimer's disease and
cardiovascular diseases. The purpose of this study was to test the hypothesis
that circulating levels of TNF-alpha represent a link between C. pneumoniae,
high prevalences of dementia and cardiovascular diseases in 126 Danish
centenarians. IgA antibody titres against C. pneumoniae were linearly correlated
with high plasma levels of TNF-alpha in centenarians. However, both parameters
were also correlated with total IgA in the blood and the association between C.
pneumoniae IgA and TNF-alpha was not significant when total IgA was included in
a multiple linear regression model. Accordingly, the association between C.
pneumoniae-specific IgA and TNF-alpha may reflect immune activation rather than
a specific antibody response. No associations were found between antibodies to
C. pneumoniae and dementia or cardiovascular diseases. Although TNF-alpha is
likely to be involved in the pathogenesis of atherosclerosis and dementia, the
present study does not support the hypothesis that TNF-alpha represents a link
between chronic C. pneumoniae infection and these disorders.

"Neuronal cell death in the visual cortex is a prominent feature of the X-linked
recessive mitochondrial deafness-dystonia syndrome caused by mutations in the
TIMM8a gene." Ophthalmic Genet22(4): 207-23.
The Mohr-Tranebjaerg syndrome (MIM 304700) and the Jensen
syndrome (MIM 311150) were previously reported as separate X-linked recessive
deafness syndromes associated with progressive visual deterioration, dystonia,
dementia, and psychiatric abnormalities. In the most extensively studied
Norwegian family, the Mohr-Tranebjaerg syndrome was reported to be caused by a
one-basepair deletion (151delT) in the deafness/dystonia peptide (DDP) gene at
Xq22. This gene has been renamed TIMM8a. We identified a stop mutation (E24X) in
the TIMM8a gene segregating with the disease in the original Danish family with
the Jensen syndrome, which confirms that the two disorders are allelic
conditions. We also report abnormal VEP examinations and neuropathological
abnormalities in affected males from the two unrelated families with different
mutations. The findings included neuronal cell loss in the optic nerve, retina,
striate cortex, basal ganglia, and dorsal roots of the spinal cord. The
demonstration of mitochondrial abnormalities in skeletal muscle biopsies in some
patients is compatible with the suggestion from recent research that the TIMM8a
protein is the human counterpart of an intermembrane mitochondrial transport
protein, Tim8p, recently characterized in yeast. The clinical and
neuropathological abnormalities associated with mutations in the TIMM8a gene
support that this X-linked deafness-dystonia-optic neuropathy syndrome is an
example of progressive neurodegeneration due to mutations in a nuclear gene
necessary for some, yet unknown mitochondrial transport function. We recommend
sequencing the TIMM8a gene, thorough ophthalmological examination, and measuring
visual evoked potentials in clinically suspected male patients with either
progressive hearing impairment, dystonia, or visual disability in order to
establish an early diagnosis and provide appropriate genetic counselling.

"Determinants for the use of psychotropics among nursing home residents." Int
J Geriatr Psychiatry16(2): 147-54.
PURPOSE: To characterise the prescription pattern of
psychotropics in Danish nursing homes and to identify diagnostic, behavioural,
cognitive and performance characteristics associated with prevalent psychotropic
drug use. METHODS: Prescribed daily medication was recorded from nurses' files.
Based on the Anatomical Therapeutical Chemical (ATC) classification index,
psychotropics were categorised into neuroleptics, benzodiazepines and
antidepressants. Two hundred and eighty-eight residents were diagnosed using the
GMS-AGECAT. One hundred and eighteen staff members were interviewed about the
residents's Activities of Daily Living (ADL), behavioural problems (Nursing Home
Behavior Problem Scale), orientation, communication skills and if the resident
had any psychiatric disorder. Multiple logistic regression was used to select
the items that determined the use of psychotropics. RESULTS: Fifty-six percent
of the residents received a psychotropic, 21% received neuroleptics, 38%
received benzodiazepines and 24% received antidepressants. In the multivariate
analysis, staff assessment of the resident's mental health was a determinant for
the use of all types of specific psychotropics, whereas a GMS-AGECAT diagnosis
only determined the use of neuroleptics. Behavioural problems were a determinant
for the use of neuroleptics and the use of benzodiazepines irrespective of the
psychiatric diagnosis of the resident. Use of antidepressants was associated
with male gender and increasing age. CONCLUSIONS: Staff perceptions of
psychiatric morbidity and norms have a greater impact on the prescription of
psychotropics than standardised clinical criteria.

Heritable influences on cognitive functioning were
investigated in a sample of 403 pairs of like-sex Danish twins aged 75 years and
older. Twins completed the Mini-Mental State Examination and 3 other cognitive
tests. Genetic factors accounted for 26-54% of the variance on these measures,
with the balance being due to environmental factors that create differences
rather than similarities among reared-together relatives. Deleting twins with
severe cognitive impairment had little effect on the results, indicating that
the heritability of cognitive functioning was not due entirely to genes
affecting dementia. Neither age nor gender moderated twin similarity, and
differential social contact could not account for correlation differences
between monozygotic and dizygotic twins. These results replicate G. E. McClearn
et al.'s (1997) study in indicating substantial genetic influences on late-life
cognitive functioning.

INTRODUCTION: Occupational exposure to electromagnetic fields
has been associated with neurological diseases, such as amyotrophic lateral
sclerosis, senile dementia, Parkinson's disease and Alzheimer's disease.
MATERIAL AND METHOD: I studied the incidence of disease in the central nervous
system in 30,631 persons employed at Danish electric companies between 1900 and
1993. I linked the cohort to the nationwide, population-based Danish National
Register of Patients and compared the number of cases of these diseases found
between 1978 and 1993 with the corresponding rates in the general population. In
addition, I fit the data on utility workers to a multiplicative Poisson
regression model in relation to estimated levels of exposure to 50 Hz
electromagnetic fields. RESULTS: Overall, there was an increase in the risk of
senile dementia and motor neuron diseases combined. The incidences of
Parkinson's disease, Alzheimer's disease and other diseases of the central
nervous system were essentially unrelated to exposure to electromagnetic fields.
A decreased risk of epilepsy compared with the general population probably
reflects a healthy worker effect; I observed an increased risk of epilepsy based
on internal comparisons. DISCUSSION: The increased risk of senile dementia and
motor neuron diseases may be associated with above average levels of exposure to
electromagnetic fields.

"Creutzfeldt-Jakob disease segregating in a three generation Danish family."
Acta Neurol Scand103(3): 139-47.
A three generation family is presented in which rapidly
progressive, early-onset Creutzfeldt-Jakob disease without typical EEG changes
segregates as an autosomal dominant disease. An aspartic acid to asparagine
mutation at codon 178 of the prion gene, PRNP, co-segregates with the disease.
As expected, the disease allele also carries the valine codon of the polymorphic
valine/methionine codon 129 of the gene. In family members homozygous for this
valine codon the disease was more rapidly progressive than in a heterozygous
family member, who had a variant clinical phenotype. Definite neuropathological
diagnosis required prion staining with specific antibodies.

13 dementia syndromes as models of neurodegeneration." Amyloid8(4):
277-84.
Two hereditary conditions, familial British dementia (FBD)
and familial Danish dementia (FDD), are associated with amyloid deposition in
the central nervous system and neurodegeneration. The two amyloid proteins, ABri
and ADan, are degradation products of the same precursor molecule BriPP bearing
different genetic defects, namely a Stop-to-Arg mutation in FBD and a
ten-nucleotide duplication-insertion immediately before the stop codon in FDD.
Both de novo created amyloid peptides have the same length (34 amino acids) and
the same post-translational modification (pyroglutamate) at their N-terminus.
Neurofibrillary tangles containing the classical paired helical filaments as
well as neuritic components in many instances co-localize with the amyloid
deposits. In both disorders, the pattern of hyperphosphorylated tau
immunoreactivity is almost indistinguishable from that seen in Alzheimer's
disease. These issues argue for the primary importance of the amyloid deposits
in the mechanism(s) of neuronal cell loss. We propose FBD and FDD, the
chromosome 13 dementia syndromes, as models to study the molecular basis of
neurofibrillary degeneration, cell death and amyloid formation in the brain.

amyloidosis, amyloid angiopathy, and their relationship to stroke and dementia."
J Alzheimers Dis3(1): 65-73.
Cerebral amyloid angiopathy (CAA) is the common term used to
define the deposition of amyloid in the walls of medium- and small-size
leptomeningeal and cortical arteries, arterioles and, less frequently,
capillaries and veins. CAA is an important cause of cerebral hemorrhages
although it may also lead to ischemic infarction and dementia. It is a feature
commonly associated with normal aging, Alzheimer disease (AD), Down syndrome
(DS), and Sporadic Cerebral Amyloid Angiopathy. Familial conditions in which
amyloid is chiefly deposited as CAA include hereditary cerebral hemorrhage with
amyloidosis of Icelandic type (HCHWA-I), familial CAA related to Abeta variants,
including hereditary cerebral hemorrhage with amyloidosis of Dutch origin (HCHWA-D),
the transthyretin-related meningocerebrovascular amyloidosis of Hungarian and
Ohio kindreds, the gelsolin-related spinal and cerebral amyloid angiopathy,
familial PrP-CAA, and the recently described chromosome 13 familial dementia in
British and Danish kindreds. This review focuses on the various molecules and
genetic variants that target the cerebral vessel walls producing clinical
features related to stroke and/or dementia, and discusses the potential role of
amyloid in the mechanism of neurodegeneration.

The term cerebral amyloid angiopathy (CAA) refers to the
specific deposition of amyloid fibrils in the walls of leptomeningeal and
cortical arteries, arterioles and, although less frequently in capillaries and
veins. It is commonly associated with Alzheimers disease, Down's syndrome and
normal aging, as well as with a variety of familial conditions related to stroke
and/or dementia: hereditary cerebral hemorrhage with amyloidosis of Icelandic
type (HCHWA-I), various inherited disorders linked to Abeta mutants (including
the Dutch variant of HCHWA), and the recently described chromosome 13 familial
dementia in British and Danish kindreds. This review focuses on four different
types of hereditary CAA, emphasizing the notion that CAA is not only related to
stroke but also to neurodegeneration and dementia of the Alzheimer's type.

"[Creutzfeldt-Jakob syndrome in the county of Storstrom during the period
1990-1999. Was there a significant accumulation of cases?]." Ugeskr Laeger163(45): 6275-9.
INTRODUCTION: In the county of Storstrom with about 250,000
inhabitants, ten cases of Creutzfeldt-Jacob disease (CJD) were diagnosed at the
Department of Neurology, Naestved County Hospital during the decade 1990-1999.
Only one case is to be expected every four years in the county. Therefore we
decided to investigate if a significant accumulation had occurred. METHODS: Case
records were examined to see whether the patients complied with the WHO criteria
for possible, probable, or certain sporadic CJD. Poisson distribution with
correction for age was used to compare the observed incidence with the expected
incidence of 1 case/million/year. RESULTS: Eight cases complied with the
diagnostic criteria: two certain, three probable, two possible, and one
familial. The incidence of certain and probable cases was 1.9 per million per
year during the period, which does not constitute a significant increase (p =
0.18). CONCLUSION: The result is consistent with the fact that all time or space
clustering of CJD ever reported has proved ascribable to familial cases, and
with the fact that case-control studies have never identified environmental risk
factors for sporadic CJD.

(2001). "Dementia is not inevitable: a population-based study of Danish
centenarians." J Gerontol B Psychol Sci Soc Sci56(3): P152-9.
The authors evaluated the prevalence of dementia in
centenarians. In this population-based survey, persons living in Denmark who
turned 100 during the period April 1, 1995--May 31, 1996 (N = 276) were
interviewed and examined at their residences. Additional health information was
retrieved from medical files, including the National Discharge Registry. A
participation rate was 75%, and no differences were found between participants
and nonparticipants regarding sex and type of housing. The prevalence of mild to
severe dementia in centenarians was 51%; 37% had no signs of dementia. Among the
105 demented centenarians, 13 (12%) had diseases (vitamin B12 and folic acid
deficiencies, hypothyroidism, Parkinson's disease) that could contribute to a
dementia diagnosis. Of the remaining 92 demented participants, 46 (50%) had 1
one or more cerebro- or cardiovascular diseases known to be risk factors in the
development of dementia. The prevalence of these risk factors was the same in
demented and nondemented participants, whereas hypertension was significantly
more frequent in nondemented than demented participants. Dementia is common but
not inevitable in centenarians. Cerebro- and cardiovascular diseases are equally
common in demented and nondemented persons.

OBJECTIVE: To assess the prevalence of common illnesses in an
unselected population of centenarians. DESIGN: A population-based survey.
SETTING: Denmark. PARTICIPANTS: All Danes who celebrated their 100th anniversary
between April 1, 1995 and May 31, 1996: 276 persons. MEASUREMENTS: All
participants (including proxies) were visited at their domicile for an interview
(sociodemographic characteristics, activities of daily living, living
conditions, need of assistance from other people, former health and current
diseases, current medication) and a clinical examination (dementia screening
test, heart and lung auscultation, neurological assessment, height and weight,
electrocardiogram, arm and ankle blood pressure, assessment of hearing and
vision capacity, a short physical performance test, bio-impedance, lung function
test, blood test). Further health information was retrieved from medical files
and national health registers. RESULTS: Seventy-five percent (207) of eligible
subjects participated in the study. Cardiovascular disease was present in 149
(72%) subjects. Osteoarthritis (major joints) was present in 54%, hypertension
(> or =140/ > or =90) in 52%, dementia in 51%, and ischemic heart disease in
28%. The mean number of illness was 4.3 (standard deviation (SD) 1.86). Only one
subject was identified as being free from any chronic condition or illness.
Sixty percent had been treated for illness with high mortality. In 25 autonomous
(nondemented, functioning well physically, living at home) and 182 nonautonomous
centenarians, comorbidities were equivalent. CONCLUSION: Because they have a
high prevalence of several common diseases and chronic conditions, Danish
centenarians are not healthy. However, a minor proportion was identified as
being cognitively intact and functioning well.

Social services estimated on September 1, 1997 that 221
individuals out of a population of about 16,000 in the whole of Ringkobing
County were believed to suffer from dementia. Citizens believed to suffer from
dementia were offered an assessment by a trained nurse and a general
practitioner. In the following six months, 119 people were screened by the nurse
with the Mini Mental State Examination, the Geriatric Depression Scale-15 and
Gottfries-Brane-Steen scale for evaluating functional deficiencies in demented
patients. In addition, somatic and laboratory screening was done by the GP's.
Approximately 40 citizens or 33% were not found to suffer from dementia but
suffered from other illnesses. One year later all the GP's answered
questionnaires concerning number of cases of depression, hypothyroidism, vitamin
B12 deficiency or other illnesses not earlier known to the GP. Twenty-two
diseases were identified and six patients improved.

duplication in the 3' region of the BRI gene originates an amyloid peptide that
is associated with dementia in a Danish kindred." Proc Natl Acad Sci U S A97(9): 4920-5.
Familial Danish dementia (FDD), also known as heredopathia
ophthalmo-oto-encephalica, is an autosomal dominant disorder characterized by
cataracts, deafness, progressive ataxia, and dementia. Neuropathological
findings include severe widespread cerebral amyloid angiopathy, hippocampal
plaques, and neurofibrillary tangles, similar to Alzheimer's disease. N-terminal
sequence analysis of isolated leptomeningeal amyloid fibrils revealed homology
to ABri, the peptide originated by a point mutation at the stop codon of gene
BRI in familial British dementia. Molecular genetic analysis of the BRI gene in
the Danish kindred showed a different defect, namely the presence of a 10-nt
duplication (795-796insTTTAATTTGT) between codons 265 and 266, one codon before
the normal stop codon 267. The decamer duplication mutation produces a
frame-shift in the BRI sequence generating a larger-than-normal precursor
protein, of which the amyloid subunit (designated ADan) comprises the last 34
C-terminal amino acids. This de novo-created amyloidogenic peptide, associated
with a genetic defect in the Danish kindred, stresses the importance of amyloid
formation as a causative factor in neurodegeneration and dementia.

The purpose of the study was to describe a Danish nursing
home population. The study consists of 288 nursing home residents (median age
84.6 years, 68% females). The psychiatric morbidity of the residents was
diagnosed with the GMS-AGECAT. The staff was interviewed about the residents'
ADL, disturbing behaviour and therapeutic measures. Seventy-one percent had a
psychiatric disorder, with organic disorder as the most frequent (61%). Demented
residents received significantly less hypnotics, were more often physically
restrained and had lower ADL levels compared to other residents. The situation
in Denmark can be seen as a paradox. While substantial effort has been made to
increase the possibility of choice and to "deinstitutionalize" nursing homes,
the majority of the residents are demented and thus not capable of making valid
choices.

BACKGROUND: White-matter hyperintensities are commonly found
on magnetic resonance imaging (MRI) of elderly people with or without dementia.
Studies of the relation between severity of white-matter hyperintensities and
cognitive impairment have had conflicting results. We undertook a longitudinal
study of age-related decline in intellectual function and MRI at age 80 years.
METHODS: From a cohort of 698 people born in 1914 and living in seven
municipalities in Denmark, 68 healthy non-demented individuals had been tested
with the Wechsler adult intelligence scale (WAIS) at ages 50, 60, and 70, and
they agreed to further WAIS testing at age 80, and cerebral MRI at age 80-82
(mean age 82.3 years). We scored separately the numbers of periventricular and
deep white-matter hyperintensities. FINDINGS: Scores for periventricular
hyperintensities in this sample included all possible degrees of severity, but
no participant scored more than 75% of maximum for deep white-matter
hyperintensities. Neither type was related to the WAIS IQs of the 80-year
assessment, but both were significantly associated with decline in performance
IQ from age 50 to age 80 years (bivariate correlation coefficients 0.32,
p=0.0087, and 0.28, p=0.0227, respectively). An analysis based on two WAIS
subtests showed that the association between white-matter hyperintensities and
cognitive impairment was significant only for cognitive decline in the decade
70-80 years. INTERPRETATION: Both periventricular and deep white-matter
hyperintensities are related to decline in intelligence but, in healthy
octogenarians, the cumulative effect of these features alone explains only a
small part of the large differences among individuals in age-related decline in
intelligence. Interpretation of the presence and severity of white-matter
hyperintensities in a diagnostic context must be done cautiously.

"[Clinical, radiological, histopathological and genetic findings in a Danish "CADASIL"
family]." Ugeskr Laeger162(12): 1739-42.
Cerebral autosomal dominant arteriopathy with subcortical
infarcts and leukoencephalopathy (CADASIL) is a rare adult-onset inherited
arterial disease with a distinctive neuropathological phenotype. Owing to its
recent identification and variable mode of presentation, the disease is often
misdiagnosed. The CADASIL gene is Notch 3 and has been mapped on chromosome
19q12 in several unrelated families. Knowledge of the phenotypic range of
CADASIL, however, remains incomplete. Clinical, pathological radiological, and
genetic findings in the first known Danish CADASIL pedigree are presented.
Genetic testing confirmed a Notch 3 mutation. The mutation consisted of the
substitution of a nucleotide at position 475 leading to the replacement of amino
acid arginine for cysteine at position 133 in the third EGF motif.

"[Prevalence and incidence of dementia in Denmark. The Odense study]." Ugeskr
Laeger162(33): 4386-90.
Prevalence and incidence of dementia were determined for
65-84 year-old persons living in the municipality of Odense and randomly drawn
from the Danish Civil Registration System (DCRS). All participants were examined
with CAMCOG, the cognitive section of CAMDEX (The Cambridge Examination for
Mental Disorders of the Elderly) and the follow-up period was two years.
Individualized CAMCOG cut-off scores were determined by multiple linear
regression. Possibly demented persons were further examined with the remaining
part of CAMDEX and neuropsychological tests. Alzheimer's disease (AD) was
diagnosed according to the NINCDS-ADRDA criteria for probable AD, and vascular
dementia (VD) and dementias of other types according to the DSM-III-R criteria
for dementia. The severity of dementia was determined according to the Clinical
Dementia Rating scale. Of the 5,237 persons drawn from the DCRS, 3,346
participated in the prevalence study and 2,452 in the incidence study. The
prevalence was 7.1% (66.7% AD, 18.3% VD, and 15.0% dementias of other types).
Ninety-six (2.8%) were diagnosed as very mildly demented. The incidence rate was
29.5 new cases per 1,000 person-years and 20.9 for AD. Inclusion of cases with
very mild dementia resulted in higher prevalence and incidence rates than
generally reported.

"[Referral from general practice to diagnostic evaluation of dementia]."
Ugeskr Laeger161(38): 5304-7.
The study objective was to describe the GP's referrals of
patients to diagnostic evaluation of dementia and the GP's perception of the
organization of this process++. The study is based on postal questionnaire
mailed to all GPs in Denmark, spring 1998. Seventy-five percent of 3379 GPs
answered the questionnaire. Seventy-one percent (1799) of the GPs had referred a
patient to diagnostic evaluation of dementia within the last 12 months.
Thirty-nine percent had referred to a geriatric psychiatric service, 36% to a
neurologic service, 18% to a psychiatric service, 11% to a geriatric service,
and 16% had referred to other services. Fifteen percent of the GPs had referred
to two or more of the services. The study concludes that there is considerable
regional variation as to where the GPs refer patients for diagnostic evaluation
of dementia as well as to the GPs perception of the possibilities of referrals
in Denmark. The implications are discussed.
Thomsen, J. S., T. Horn, et al. (1999). "[Amyloidosis.
A review]." Ugeskr Laeger161(21): 3079-83.
Amyloidosis is a heterogenous group of diseases, all
characterized by extracellular deposition of amyloid either systemically or
localized. Of wellknown diseases are Alzheimer's dementia, AL-amyloidosis (e.g.
in multiple myeloma) and AA-amyloidosis (e.g. in rheumatoid arthritis). Amyloid
is composed of three components of which the fibrillary component is the basis
of amyloid classification. Many types of amyloid have a systemic distribution
and give rise to varying symptoms. The diagnosis is based on biopsy, preferably
of abdominal subcutis. The prognosis is poor, however, recent investigations on
the three-dimensional structure of the P-component provide hope for future
therapy.
Romero, I., P. Jorgensen, et al. (1999). "A
presenilin-1 Thr116Asn substitution in a family with early-onset Alzheimer's
disease." Neuroreport10(11): 2255-60.
Mutation in the presenilin-1 (PS-1) gene at chromosome
14q24.3 is the most common cause of autosomal dominant early-onset Alzheimer's
disease. Here, we report a novel missense mutation in the presenilin-1 gene
found in a three-generation Danish family with autopsy-verified early-onset
Alzheimer's disease. Two affected first-degree relatives in two generations were
found to be heterozygous for a cytosine to adenine transversion at the second
position of codon 116, which changes the amino acid at that position from
threonine to asparagine. This conservative amino acid substitution occurs in an
evolutionary highly conserved region of the PS-1 protein and is associated with
onset of the disease between age 35 and 41 years and 4-8 years' duration of the
disease. Analysis of amyloid beta-protein (A beta) deposition in brain specimens
from one affected family member showed predominance of A beta 42(43). Onset and
progression of the disease were very similar in two sibs homozygous for the
epsilon 3 allele and the epsilon 4 allele, respectively, of the polymorphic
apolipoprotein E locus. The lack of effect of the high risk epsilon 4/epsilon 4
genotype on the disease in this family corroborates and extends previous
observations that the presence of one copy of the epsilon 4 allele does not
modulate PS-1 associated Alzheimer's disease.

referrals to an interdisciplinary team of consulting specialists]." Ugeskr
Laeger161(43): 5915-9.
During a period of 22 months 147 consecutive residents with
behavioural disturbances from 80% of the Copenhagen nursing homes were referred
to a visiting team of consulting specialists. Each resident was evaluated
clinically, and data were recorded in a database. The conditions thought to
represent the underlying etiologies were dementia (79%), delirium (28%) and
depression (35%). The most commonly observed behavioural symptoms were
aggressiveness, vocally disruptive behavior and non-aggressive psychomotor
symptoms. The most common interventions suggested by the team were further
diagnostic evaluations, adjustment of pharmaceutical treatment, using the life
history of the resident as a reference for behaviour management, and
psychological behavior management. There is a need for increased focus on
systematic diagnosis and treatment of behavioural disorders, observed in nursing
homes, which often have multifactorial etiology.

"[Dementia paralytica is still seen in Denmark]." Ugeskr Laeger161(18):
2682-3.
Two cases of neurosyphilis are presented. Both patients had
developed a paranoid psychosis and needed admission to a psychiatric department.
In both cases relevant treatment resulted in improvement of both the dementia
and the psychotic condition, though the patients were left with some degree of
dementia at follow up. Both patients had a symptom-free interval lasting several
years. It still remains important to take WR, when investigating the cause of
dementia, and when dealing with patients admitted to neurological and
psychiatric departments with an uncertain diagnosis.
Malling, B. J. (1999). "[Malignant neuroleptic
syndrome in patients with dementia]." Ugeskr Laeger161(17):
2541-2.
The neuroleptic malignant syndrome (NMS) is a side-effect of
treatment with neuroleptic drugs. It is infrequent, but underdiagnosed. The
diagnosis can be especially difficult to verify, in older patients with dementia
because they often have symptoms of NMS, as a consequence of age and dementia.
The importance of monitoring serum-creatine-kinase is discussed and proposals
for treatment are suggested.
Lien, K., C. Fensbo, et al. (1999). "[Dementia
and psychiatric service]." Ugeskr Laeger161(38): 5313-6.
The study objective was to describe the service provision in
geriatric psychiatry in 1997 and the trends in admission patterns for the
elderly to psychiatric hospitals in Denmark from 1988 to 1996. Information
concerning admission pattern was obtained from the Danish Psychiatric Case
Register. The information on the supply of geriatric psychiatric services was
collected by a questionnaire to the individual geriatric psychiatric
departments. All geriatric psychiatric departments in Denmark have been
identified. The number of demented patients admitted to psychiatric hospitals
decreased considerably as did the length of stay for demented patients admitted
from 1988 to 1996. For all other diagnoses the number of admissions increased in
the same period. Four counties out of 14 did not have a special unit for
geriatric psychiatry. There were considerable geographical variations in supply
as well as target groups in the counties that supplied geriatric psychiatric
service. The unequal access to geriatric psychiatric services and variations in
target groups underlines the need for a discussion of future directions for this
service provision.

"Dementia in affective disorder: a case-register study." Acta Psychiatr Scand100(3): 176-85.
OBJECTIVE: The aim of the study was to investigate whether
patients with affective disorder have increased risk of developing dementia
compared to other groups of psychiatric patients and compared to the general
population. METHOD: In the Danish psychiatric central register, 3363 patients
with unipolar affective disorder, 518 patients with bipolar affective disorder,
1025 schizophrenic and 8946 neurotic patients were identified according to the
diagnosis at the first ever discharge from psychiatric hospital during the
period from 1970 to 1974. The rate of discharge diagnosis of dementia on
readmission was estimated during 21 years of follow-up. In addition, the rates
were compared with the rates for admission to psychiatric hospitals with a
discharge diagnosis of dementia for the total Danish population. RESULTS:
Patients with unipolar and with bipolar affective disorder had a greater risk of
receiving a diagnosis of dementia than patients with schizophrenia and those
with neurosis. All groups of patients had a higher risk of being given a
diagnosis of dementia than gender- and age-matched samples of the general
population. CONCLUSION: Patients with affective disorder appear to be at
increased risk of developing dementia.

elderly in general psychiatry]." Ugeskr Laeger161(19): 2807-10.
The Danish National Board of Health recommends that the
counties offer psychogeriatric services. The target group for geriatric
psychiatry in the County of North Jutland only concerns elderly people with
severe dementia. It has been our aim to describe and discuss the geriatric
psychiatric supply of services and admission pattern for elderly with
psychiatric morbidity in the County of North Jutland. We have made a
cross-sectional study of all patients referred to the general and
psychogeriatric service in 1997. In psychogeriatric service 40 of 46 referrals
were dealt with as out-patient contact. In general psychiatry the 57 referrals
resulted in 33 admissions of which 31 were acute. There is a high number of
acute admissions in general psychiatry. The County of North Jutland does not
have a suitable service for diagnostic work-up and treatment of people with
possible to moderate dementia.

"[Treatment of delirium in a psychogeriatric university hospital department.
Etiology, treatment concept and outcome]." Ugeskr Laeger161(14):
2090-4.
The purposes of the study were to account for aetiology,
treatment concept, outcome of treatment, and discharge destination of delirious
elderly inpatients. During one year all patients in a psychogeriatric university
department were assessed on admission and at discharge with a selection of
assessments measuring psychopathology, behavioural disorders, depressive
symptoms, intellectual functioning, activities of daily living, and gait.
Diagnoses were made according to the ICD-10 criteria for research. All patients
with a principal diagnosis of delirium (n = 26) are accounted for. Delirious
patients improved their health status significantly in all the assessments, and
86% of patients admitted from independent living were discharged to independent
living. It is concluded that elderly inpatients with severe or prolonged
delirium profit significantly from the treatment concept in all of the rated
health aspects.

"Concurrent validity of the GMS-AGECAT (A3) package in a Danish nursing home
population." Int J Geriatr Psychiatry13(5): 336-42.
AIM: To validate the Danish version of the GMS-AGECAT (A3),
the Standardized Mini Mental State Examination (SMMSE) and the Geriatric
Depression Scale-15 (GDS-15) by comparing them to clinical ICD-10 criteria in a
Danish nursing home population. METHODS: With a participation of 91%, the study
included 100 residents. All residents were interviewed with the GMS-AGECAT (A3),
SMMSE and GDS-15 by an MD and then blindly diagnosed by a consultant geriatric
psychiatrist. All residents approached for an interview were included, also
those who were not able to communicate (the non-accessibles). RESULTS: The
prevalence of clinical psychiatric ICD-10 main diagnoses was 56%. The
non-accessibles had significantly higher psychiatric morbidity and lower ADL
scores (modified Barthel ADL index) compared to those who were able to
communicate. With the non-accessibles (N = 100) included, the optimal screening
and diagnostic cutpoint for the GMS-AGECAT organic diagnoses was 2/3, with 96%
sensitivity, 73% specificity, 77% predictive value of a positive test and 95%
predictive value of a negative test. The SMMSE and GDS-15 had better screening
properties compared to the GMS-AGECAT but only 60% of the residents were able to
complete the SMMSE and 78% were able to complete the GDS-15. CONCLUSION: The
Danish version of the GMS-AGECAT has relevant diagnostic and screening
properties for organic disorders in Danish nursing home populations.

Laeger160(11): 1617-20.
CADASIL (Cerebral Autosomal Dominant Arteriopathy with
Subcortical Infarcts and Leucoencephalopathy) is a newly discovered inherited
cerebrovascular disease characterized clinically by recurrent stroke-like
incidents, dementia and often pseudobulbar palsy. Neuroimaging reveals intensive
subcortical changes and pathologically one finds apparently systemic changes
concerning the vessels such as thickening of the vessel wall, loss of smooth
muscle cells and patches of granular material of unknown origin. The disease is
not associated with atherosclerosis and vascular risk factors are missing or
few. The CADASIL-locus maps to chromosome 19, but the gene has not yet been
identified. Treatment and pathogenesis are unknown. In a Danish stroke
population (The Copenhagen Stroke Study) no CADASIL-suspected cases were found
among patients < or = 55 years, indicating a rare disease as far as Denmark is
concerned.

The mini-mental state examination (MMSE) is one of the most
widely used screening instruments for the detection of cognitive impairments,
used primarily in connection with screening for dementia. The intent of this
review is to describe the original purpose of the MMSE and how it is currently
used in clinical practice and in research. Advantages and limitations of the
MMSE in providing a valid diagnosis of cognitive impairments (dementia) are
discussed including sensitivity and specificity, the issues of the relationship
of the MMSE scores to sociodemographic variables and examinations of factor
structures of the MMSE. It is concluded that the MMSE provides a valid diagnosis
of cognitive impairments among people with moderate and severe dementia in
general populations. However, MMSE is not recommended as a screening instrument
for the detection of early stages of dementia. Studies are needed to extend the
present knowledge about how or whether the MMSE can be used in the clinical
diagnostic evaluation of dementia and how demented patients treated with
medications should be monitored.

156(2): 152-7.
Machado-Joseph disease (MJD) is an autosomal dominantly
inherited neurodegenerative disorder characterized by varying age of onset and
pronounced phenotypic heterogeneity. The clinical core features include gait
ataxia, external ophthalmoplegia, nystagmus, and bulging eyes. Recently,
Kawagushi et al. (1994) cloned the MJD1 gene on chromosome 14 and MJD turned out
to be the fifth neurodegenerative disease caused by an unstable CAG repeat
expansion. We have studied two large Danish families and one Norwegian family
with MJD. Three features not previously associated with MJD are reported:
dementia, generalized muscle and joint pain, and in one case neuropathological
examination revealed atrophy of the inferior olives. We found a significant
inverse correlation between age of onset and the length of the CAG repeat
expansion, and anticipation is described through four succeeding generations.
Instability of the CAG repeat expansion was most pronounced at paternal
transmission.

In 1986, veterinary pathologists discovered spongiform
encephalopathy in the brains of two cows in the UK. These two cases turned out
to be the beginning of epidemic bovine spongiform encephalopathy (BSE), which
culminated in 1992 with more than 3000 cases monthly. In 1996, the British
government announced that a distinct variant of CJD (vCJD) had occurred in ten
young people in the UK. The cases were notified within the past 1 1/2 years. A
link to BSE seemed likely. Transmission studies of the two diseases have
demonstrated similar properties such as incubation time, neuropathology and
glycoform profile of the pathologically altered prionprotein. In effect, vCJD is
very likely to represent human BSE. Epidemiological data suggest that BSE
transmission to humans may have occurred only in a limited number of cases.
Future studies will have to confirm this. So far, no increase in the incidence
of vCJD has been noticed.
