OBJECTIVES: The study aimed to increase understanding of behavioural changes in frontotemporal dementia (FTD) and identify features that best differentiate FTD from Alzheimer's disease (AD) and cerebrovascular dementia (CvD). METHODS: A semi-structured questionnaire was administered to carers of 30 FTD, 75 AD and 34 CvD patients. RESULTS: Behavioural changes that strongly discriminated FTD from AD and to a lesser extent CvD were loss of emotions and insight, selfishness, disinhibition, personal neglect, gluttony and sweet food preference, wandering, motor and verbal stereotypies, loss of pain, echolalia and mutism. Irritability, hyposexuality and hypersomnia did not discriminate. Emotional, eating and stereotyped behaviours correctly classified 95% of patients using regression analysis. CONCLUSIONS: Behavioural characteristics accurately differentiate FTD from AD and CvD. The findings highlight the particular importance of affective change in FTD, and underline the role of the frontotemporal lobes in emotion. 相似文献

Serum paraoxonase activity changes in patients with Alzheimer's disease and vascular dementia 总被引:9,自引:0,他引:9

The prevalence of Alzheimer's disease (AD) and vascular dementia (VAD) increases with aging of the population. The role of
lipoproteins in the pathogenesis of AD is unclear: apoE2 offers protection and apoE3 is neutral, while apoE4 promotes the development of the disease.
Recently, several studies have confirmed the role of oxidative stress in the pathogenesis of AD and VAD. HDL-associated paraoxonase
is one of the antioxidative enzymes that may reduce LDL oxidation. In our study, we investigated the lipid parameters of the
sera and the serum paraoxonase activity in patients with AD and VAD.
Lipid parameters were determined by an autoanalyzer in 30 AD patients, 40 VAD patients and 40 healthy, age-matched control
(C) subjects. Paraoxonase activity was measured spectrophotometrically using paraoxon as the substrate. The phenotypic distribution
of paraoxonase was determined by the dual substrate method, using paraoxon and phenylacetate as substrates.
In our results, we found that most of the patients with AD had the apoE4 isoform, consistent with other studies. In the VAD
and AD patients we found significantly higher total-cholesterol compared to the control group (C: 4.71 ± 0.89, VAD: 6.3 ±
0.8, AD: 6.52 ± 0.7 mmol/l; p < 0.01) and LDL-cholesterol levels (C: 2.6 ± 0.6, VAD: 3.96 ± 0.8, AD: 3.84 ± 0.6 mmol/l; p
< 0.001). The HDL-associated antioxidant, paraoxonase activity did not differ significantly in the patient groups, but compared
to the healthy control subjects, paraoxonase activity was significantly lower in both of the patient groups (C: 188 ± 55 U/l;
AD: 131 ± 37, VAD: 151 ± 50 l; p < 0.05).
Our results suggest that the defect in HDL-associated antioxidant capacity plays a role in the pathogenesis of Alzheimer's
disease and vascular dementia.

Background: Olfactory function in vascular dementia has not been extensively investigated to date. We studied olfactory function in vascular dementia (VD) and dementia of Alzheimer's type (DAT). Methods: We studied olfactory functioning in 12 patients suffering from dementia of Alzheimer's type, 11 patients with vascular dementia and 30 normal subjects. For these subjects we examined a 12‐item version of the Pennsylvania smell identification test and mini‐mental state examinations. These three groups were matched for age, sex and educational level. Results: Although the dementia scores were comparable in the DAT and VD groups, the smell identifications were low in DAT patients compared with VD patients and normal control subjects. Conclusions: These results suggest that the smell identification test may be useful in differential diagnosis between DAT and VD patients 相似文献

We examined patterns of early and late word generation in category and letter fluency among persons in the preclinical stages of Alzheimer's disease (AD) and vascular dementia (VaD). The sample consisted of 20 preclinical VaD persons, 66 preclinical AD persons, and 267 control persons, sampled from the community. Persons in the preclinical phase of AD and VaD were similarly impaired in letter fluency, although the preclinical VaD group outperformed their AD counterparts in category fluency. This pattern of results is consistent with the notion that category fluency is relatively more dependent on the medial-temporal lobe, whereas letter fluency relies more on frontal regions. The patterns of fluency impairment in preclinical AD and VaD generalized across early and late word retrieval. 相似文献

Prevalence of Alzheimer's disease, vascular dementia and dementia with Lewy bodies in a Japanese population 总被引:4,自引:0,他引:4

We studied the prevalence of dementing disorders in a rural town of Japan (Amino-cho), using a door-to-door two-phase design. Of the 170 persons screened as having cognitive impairment, 142 cases were diagnosed as having dementia. The prevalence (cases/100 aged 65 years older) was 3.8 for all types of dementia, 2.1 for Alzheimer's disease (AD), 1.0 for vascular dementia (VD) and 0.7 for other types of dementia. Among other types of dementia, there were four male patients with dementia with Lewy bodies (prevalence: 0.1), but no patients with frontotemporal lobar degeneration. The overall prevalence was higher in women for AD, while that of VD was the same in both sexes. With results similar to many previous studies in Western countries and some recent surveys in Japan, the present sudy clearly showed that AD is more prevalent than VD. 相似文献

The purpose of this study was to determine whether cognitive test performances alone could distinguish patients with probable Alzheimer's disease from those with probable vascular dementia. Sixty-eight outpatients with clinical diagnoses of either Alzheimer's disease or vascular dementia were administered a brief battery of neuropsychological tests. Scores from the Boston Naming Test and the Hopkins Verbal Learning Test were identified as most discriminating of the groups. Seventy-seven per cent of the sample was correctly classified by a stepwise discriminant function analysis. Results of this study indicate that selected neuropsychological tests have moderate concurrent utility in the differential diagnosis of dementia. 相似文献

Apolipoprotein E polymorphism, Alzheimer's disease and vascular dementia among elderly Finnish men 总被引:3,自引:0,他引:3
J. H. Stengård J. Pekkanen R. Sulkava C. Ehnholm T. Erkinjuntti A. Nissinen 《Acta neurologica Scandinavica》1995,92(4):297-298
An association between late-onset Alzheimer's disease, vascular dementia and the common polymorphic alleles of the gene coding for apolipoprotein E, ɛ2, ɛ3 and ɛ4, was assessed in a population sample of 393 elderly Finnish men aged 70 to 89 years. Of them, 7%, suffered Alzheimer's disease and 3% had vascular dementia. Among those who suffered Alzheimer's disease, there was a statistically significant excess of the ɛ4 allele. No such an association was observed between the apolipoprotein E alleles and vascular dementia. We conclude that the apolipoprotein E polymorphism confers information about a risk of Alzheimer's disease in this population sample of elderly Finnish men. 相似文献

We examined serum and cerebrospinal fluid (CSF) of 16 patients with Alzheimer's disease (AD), 28 patients with vascular dementia (VD), their age-matched controls and multiple sclerosis (MS) patients in order to evaluate the humoral immune response within the central nervous system both quantitatively and qualitatively. Intra-blood-brain barrier (BBB) protein synthesis was calculated by CSF IgG index. The presence of oligoclonal banding (OCB) was investigated with agarose isoelectric focusing (IEF) followed by immunoblotting with antihuman IgG. No patient with AD and only 4 patients with VD had slightly elevated IgG indexes, and no statistically significant differences in the indexes were found between the two groups. No bands were found in the CSF of AD patients but 3 VD patients had OCB in both serum and CSF. One VD patient had bands in serum but no bands in CSF. No kappa or lambda free light chains were found in those demented patients with demonstrable bands in the CSF and serum. No OCB were found in control sera and CSF. For comparison, the majority of patients with MS had OCB in CSF. Thus, no consistent increase of intrathecal protein synthesis was found in patients with AD and VD. Methodological differences explain at least part of the conflicting results published earlier. 相似文献

Cognitive deficits of mild dementia:A comparison between dementia of the Alzheimer's type and vascular dementia 总被引:1,自引:0,他引:1

Abstract This study was designed to examine the profiles of cognitive deficits in 11 mildly demented patients with dementia of Alzheimer's type (DAT), five with vascular dementia with multiple subcortical lacunar infarcts (VDS), and seven with vascular dementia with extensive white matter lesions (VDW) in comparison with 23 aged individuals without dementia. Memory, attention, abstract thinking, and visuospatial function were assessed using the Japanese translation of the Wechsler Memory Scale-Revised (WMS-R) and the Japanese version of the Wechsler Adult Intelligence Scale-Revised (WAIS-R). Compared with normal aged individuals, three dementia groups were significantly impaired in the memory and abstract thinking. However, the performances on several tests on attention (i.e. Mental Control and Visual Memory Span Backward from WMS-R) and visuospatial function (i.e. Object Assembly from WAIS-R) differed significantly between the DAT and VDS groups, with VDS being the worst in terms of performance than was DAT. This study suggests that, in the mildly demented stage, the patients with DAT have few problems in the attention and visuospatial function, but those with VDS have impairments in these cognitive abilities. 相似文献

INTRODUCTION: Cystatin C, a cysteine protease inhibitor, has been implicated in the neurodegenerative and repair processes of the nervous system, and the deposition of the same protein together with beta amyloid peptide was found as cerebral amyloid angiopathy (CAA) in different types of dementias. OBJECTIVE AND METHODS: Because of the differential diagnostic importance, serum and cerebrospinal fluid (CSF) cystatin C levels of 24 late onset Alzheimer's demented (AD) and 16 ischemic type of vascular demented (VD) probands were compared with 17 aged control (AC) persons. RESULTS: The serum and CSF cystatin levels were found in the normal range in all groups. The ischemic VD probands had the tendency to have higher cystatin C levels than the AD. No correlation has been found with the severity and duration of dementia and with the other measured parameters. CONCLUSION: These results indicate that lower than normal CSF cystatin C level is not a diagnostic marker in ischemic VD and CAA related to AD. 相似文献

Background/Aims:
The aim of the following study is to compare the behavioral and psychological symptoms of dementia (BPSD) in patients of Alzheimer disease (AD) and vascular dementia (VaD).Materials and Methods:
We used National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer''s Disease and Related Disorders Association criteria for diagnosing AD and National Institute of Neurological Disorders and Stroke-Association International pour la Recherche et l’Enseignement en Neurosciences Criteria for diagnosing VaD. VaD cohort was further subcategorized into small vessel and large vessel disease. The severity of cognitive impairment and the BPSD were studied by means of the Clinical Dementia Rating Scale (CDR) and the Neuropsychiatric Inventory respectively.Results:
We studied 50 AD and 50 VaD patients of whom 38 were small vessels and 12 were large vessels VaD. The severity of dementia was comparable in both groups. The agitation/aggression, depression/dysphoria, anxiety, apathy/indifference, irritability, aberrant motor behavior, appetite and eating behavior and night-time behaviors occurred significantly more frequently in patients with VaD than AD. We found a weak positive correlation between the CDR score and the number of neuropsychiatric symptoms per patient in both cohorts. Elation/euphoria, agitation/aggression was significantly more frequent in patients with large vessel in comparison to small vessel VaD.Conclusions:
BPSD are common in both types of dementia and they are more severe in VaD than AD when the groups have similar levels of cognitive impairment. 相似文献16.

Neuropsychological differentiation between normal aging, Alzheimer''s disease and vascular dementia 总被引:4,自引:0,他引:4
T. Erkinjuntti R. Laaksonen R. Sulkava R. Syrjäläinen J. Palo 《Acta neurologica Scandinavica》1986,74(5):393-403
A random sample of 182 elderly community residents and 211 demented patients were studied using the D-Test Battery based on the Luria's neuropsychological investigation method. A steady but selective cognitive impairment was observed with increasing age in normal healthy subjects. The most sensitive areas of cognition to the effects of normal aging were mnestic and conceptual functions, as well as arithmetical skills. The age-related changes could be clearly differentiated from the changes found in patients with mild degree of dementia. The test also differentiated patients with mild, moderate and severe dementia from each other on the basis of their social competence. It failed to demonstrate specific patterns of impairment and to clearly differentiate between patients with Alzheimer's disease and vascular dementia who had the same degree of cognitive decline. Further qualitative analyses are needed to improve the sensitivity and specificity of the test. 相似文献

The aim of this study
was to investigate whether a brief
neuropsychological battery consisting
of a limited number of cognitive
tests and an evaluation of the
behavioural domains intended to
discriminate between frontotemporal
dementia (fv–FTD) and
Alzheimer's disease (AD), constitutes
a useful instrument for making
a differential clinical diagnosis
between these two pathologies.
Nineteen fv–FTD and 39 AD patients
were compared on cognitive
tasks (assessing memory, executive
functions, language and constructional
praxis) and on the NPI behavioural
assessment. A stepwise
discriminant analysis was performed
to identify the linear combination
of cognitive and behavioural
measures able to best
discriminate between the two
groups. One test for each of the
investigated cognitive domains
(Delayed Prose Recall, FAS verbal
fluency, Boston naming test, Rey's
Figure A Copy) and the four
subscales of the Neuropsychiatry
Inventory (NPI) which best differentiated
between fv–FTD and AD
patients (apathy, disinhibition,
euphoria, aberrant motor behaviour)
were used. The analysis
selected Rey's Figure A Copy, FAS
verbal fluency and NPI apathy subscale
as the best discriminants between
fv–FTD and AD patients. The
final equation assigned 73.7% of
the fv–FTD patients and 94.7% of
the AD patients to the correct diagnostic
group. A validation study
conducted on a new independent
sample of 11 fv–FTD and 22 AD patients
confirmed the high sensitivity
(82.6 %) and specificity (81.8%)
of the diagnostic equation in assigning
fv–FTD and AD patients to
the correct dementia group.
Although both cognitive and behavioural
differences exist between
FTD and AD, previous studies have
aimed at differentiating the two
pathologies by considering the two
aspects separately and discriminant
analyses were focused only on
neuropsychological or neuropsychiatric
evaluations. The present
results emphasise the importance
of rating both cognitive and behavioural
clinical features of the two
syndromes as objectively as possible
to improve differential diagnostic
accuracy. 相似文献

In order to clarify the association between apolipoprotein E4 (ApoE4) and the pathogenesis of Alzheimer's disease (AD), we analyzed the distribution of the apolipoprotein E (ApoE) phenotypes and the frequency of the apo E alleles epsilon2, epsilon3, and epsilon4 in Japanese healthy controls (n = 1090, an average age of 51.2+/-12.6 years) and demented patients (n=103, mean age of 73.6+/-9.2 years). Demented subjects were divided into three subgroups: early-onset AD group (EOAD; n=25, mean age 63.0+/-6.2 years), late-onset AD group (LOAD; n=33, mean age 79.3+/-5.1 years), and vascular dementia group (VD; n=45, mean age 75.3+/-8.0 years). The apolipoprotein E phenotype was determined by isoelectric focusing and immunoblotting. There were no significant differences in the distribution of the apo E phenotypes by gender or age, and the estimated frequencies of epsilon2, epsilon3 and epsilon4 were 0.05, 0.86 and 0.09, respectively, in the normal controls. There was a significant difference in the distribution of the apo E phenotypes between LOAD and elderly controls aged more than 65 years (P<0.0001). The distribution of the apo E phenotypes in EOAD was the same as that in LOAD. The frequency of the epsilon4 allele was significantly higher in LOAD (0.35, P<0.0001) and EOAD (0.28, P<0.0001) than that in the control subjects (0.07), but not in VD (0.12, P=0.1630). The present findings suggest that ApoE4 is related with both EOAD and LOAD, but not with VD, and support the hypothesis that it is a genetic risk factor of AD. 相似文献
