PSYCHOMETRICS ,ALZHEIMER'S disease - Abstract
This study was performed to assess interrater reliability of the Japanese version of the Physical Self-Maintenance Scale (PSMS) and the Instrumental Activities of Daily Living Scale (IADL), which are simple and efficient assessment instruments of functional abilities in elderly patients. The subjects were 25 consecutive patients with Alzheimer's disease who were outpatients of the Department of Neuropsychiatry in Ehime University School of Medicine and their principal caregivers. One neuropsychiatrist administered the PSMS and IADL, and all sessions were videotaped. Then one clinical psychologist, one public health nurse and one neurologist, and one occupational therapist from another institution, viewed the videotape and performed reassessments. All interrater reliabilities between the neuropsychiatrist and the neurologist, the public health nurse, the clinical psychologist and the occupational therapist were extremely good. Interrater reliability between the public health nurse and the clinical psychologist, between the clinical psychologist and the neurologist and between the public health nurse and the neurologist was also extremely good. The PSMS and IADL showed good interrater reliability between personnel from different disciplines. They are likely to be useful tests for everyday medical consultations and for field research.

- Abstract
Background: Semantic dementia (SD) has been recognized as a representative of dementia with presenile onset; however, recent epidemiological studies have shown that SD also occurs in the elderly. There have been few studies about the differences of clinical profiles between early-onset SD (EO-SD) and late-onset SD (LO-SD). Age-associated changes in the brain might cause some additional cognitive and behavioural profiles of LO-SD in contrast to the typical EO-SD cases. The aim of the present study was to clarify the characteristics of neuropsychological, and behavioural and psychological symptoms of dementia (BPSD) profiles of LO-SD patients observed in screening tests in comparison with EO-SD patients and late-onset Alzheimer's disease (LO-AD) patients as controls., Methods: Study participants were LO-SD (n = 10), EO-SD (n = 15) and LO-AD (n = 47). We examined the Mini-Mental State Examination (MMSE), the Raven's Coloured Progressive Matrices (RCPM), the Short-Memory Questionnaire (SMQ), the Neuropsychiatric Inventory (NPI) and the Stereotypy Rating Inventory (SRI)., Results: Both SD groups scored significantly lower than the LO-AD patients in 'naming' of the MMSE. In the 'construction' score of the MMSE and the RCPM score, however, the LO-SD patients as well as the LO-AD patients were significantly lower than the EO-SD patients. In the SMQ score, 'euphoria' and 'disinhibition' scores of the NPI, the SRI total and subscale scores, both SD groups were significantly higher, whereas in the 'delusion' score of the NPI, both SD groups were significantly lower than the LO-AD patients., Conclusions: Visuospatial and constructive skills of LO-SD patients might be mildly deteriorated compared with EO-SD patients, whereas other cognitive and behavioural profiles of LO-SD are similar to EO-SD. Age-associated changes in the brain should be considered when we diagnose SD in elderly patients., (© 2011 The Authors. Psychogeriatrics © 2011 Japanese Psychogeriatric Society.)

- Abstract
Frontotemporal dementia (FTD) is a subtype of frontotemporal lobar degeneration, which also includes semantic dementia (SD) and progressive non-fluent aphasia. Frontotemporal dementia is characterized by changes in personality and behavioral abnormalities, generally associated with predominant frontal lobe atrophy. Conversely, SD is typically characterized by Gogi (word meaning) aphasia based on semantic memory impairment and is associated with predominant temporal lobe atrophy. However, in the present cases, we diagnosed FTD on the basis of clinical symptoms, such as disinhibition, indifference, and stereotypy, without semantic memory impairment, even though neuroimaging showed predominant temporal lobe atrophy. We suggest that clinical symptoms are the most important cues for an accurate clinical diagnosis and there is no exclusive relationship between the syndrome and atrophy of the temporal lobes.

- Abstract
Background/aim: Some recent studies mentioned that late-onset frontotemporal dementia (FTD) is more common than previously assumed. Although much research has been done in the field, there are no systematic studies which have compared clinical characteristics of early- and late-onset FTD. The aim of this study was to compare cognitive function and psychiatric symptoms in patients with early- and late-onset FTD., Methods: Study participants were consecutive outpatients. There were 35 FTD patients; their mean age at onset was 63.0 years. We studied sex, education, duration from onset to consultation, Clinical Dementia Rating (CDR) scores, Mini-Mental State Examination (MMSE) scores, Raven's Coloured Progressive Matrices (RCPM) scores, and Neuropsychiatric Inventory (NPI) scores at first consultation of early- and late-onset FTD patients., Results: There were no significant differences in sex ratio, education, CDR scores, and duration from onset to consultation. There were significant differences in the total MMSE scores, 'three-word recall task', 'construction task', and RCPM scores; late-onset groups scored significantly lower than early-onset groups. There were significant differences in the apathy domain of NPI and total NPI scores; late-onset groups scored significantly higher than early-onset groups., Conclusion: Late-onset FTD patients may have memory and visuospatial deficits in addition to their behavioural changes, even if they are clinically diagnosed according to consensus diagnostic criteria. They also present more apathy, and they may have a different histolopathological background., ((c) 2008 S. Karger AG, Basel)

- Abstract
Recent researches have suggested that brain-derived neurotrophic factor (BDNF) may be implicated in the pathophysiology of mood disorder. This study examined the association between the BDNF Val66Met polymorphism and major depressive disorder (MDD) in a Japanese population. We genotyped the BDNF Val66Met polymorphism in 154 major depressive patients and 154 age- and sex-matched control subjects. The genotypic distributions and allele frequencies were similar among the patients and control subjects. When the relationships of the polymorphism with several clinical variables (i.e., age, sex, age of onset, number of episode, presence of psychotic features, suicidal behavior, and family history) were examined, the dose of Met allele had significant effects on psychotic feature and suicidal behavior and family history. These results suggest that the BDNF Val66Met polymorphism is not related to the development of MDD but related to clinical features of MDD in a Japanese population., (2007 Wiley-Liss, Inc.)

- Abstract
Background: When comparing with early-onset Alzheimer's disease (EO-AD) and late-onset Alzheimer's disease (LO-AD), some symptomatological differences in clinical features can be seen between them. Rapid progression, more severe language problems or visuospatial dysfunction occur more often in EO-AD patients. However, there have been very few reports about the differences in behavioral and psychological symptoms between these two groups., Aim: The aim of this study was to demonstrate the differences in behavioral symptoms between EO-AD and LO-AD groups., Method: Three hundred and seven consecutive outpatients with AD were put into an EO-AD group (46 patients) or a LO-AD group (261 patients). Comprehensive assessment batteries, including the Neuropsychiatric Inventory (NPI), were administered at the first medical assessment., Results: Significant differences were found between the EO-AD and LO-AD groups in terms of NPI total score (EO-AD: 10.3 +/- 10.9, LO-AD: 17.8 +/- 17.0, p = 0.004) and number of patients who experienced each NPI subscale score (delusion; EO-AD: 13.0%, LO-AD: 50.6%, p < 0.001). There were no differences in cognitive functions or dementia severity between two groups., Conclusion: In EO-AD, behavioral and psychological symptoms are relatively fewer than LO-AD at the first medical assessment., (Copyright (c) 2007 John Wiley & Sons, Ltd.)

- Abstract
Vascular endothelial growth factor (VEGF) has been implicated in neuronal survival, neuroprotection, regeneration, growth, differentiation, and axonal outgrowth, which are known to be involved in the pathophysiology of major depressive disorder (MDD). Recently, the VEGF mRNA expression in the peripheral leukocytes from Alzheimer's disease or cardiovascular disease was reported to be changed. We hypothesized that the expression of the VEGF mRNA in the peripheral leukocytes may be a good candidate for the biological marker for MDD. Thirty two patients with MDD and age- and sex-matched control subjects were included in this expression study. The VEGF mRNA levels in the peripheral leukocytes from drug-naive MDD patients were significantly higher than those from the control subjects and the magnitude of the decrease of VEGF mRNA after 8-week treatment significantly correlated with clinical improvement. Then, we genotyped two single nucleotide polymorphic markers of VEGF gene, which were reported to be associated with amyotrophic lateral sclerosis and Alzheimer's disease, in patients with MDD and control subjects (n=154, each). We did not find any significant association between these markers and MDD or its clinical subtypes. Our investigation indicates that the higher expression levels of VEGF mRNA in the peripheral leukocytes are associated with the depressive state and their recovery after treatment may be associated with the clinical improvement.

- Abstract
Aims: To investigate the frequency, rate of causes of dementia, and clinical characteristics of early-onset dementia in consecutive patients of a memory clinic., Methods: A total of 668 consecutive demented patients were involved in this study. We examined the distribution of patients' diagnosis, differences in sex, education, dementia severity and cognitive function at the first visit, and the duration from onset to consultation. We also examined the changes in the proportion of subjects during the research period., Results: There were 185 early-onset patients, 28% of all demented patients. No significant differences were observed between the early-onset and late-onset dementia groups in Clinical Dementia Rating and Mini-Mental State Examination score at the first consultation, but the duration from onset to consultation was significantly longer in the early-onset group. In the early-onset group, the rates of patients with Alzheimer's disease and dementia with Lewy bodies were relatively low and the rate of patients with frontotemporal lobar degeneration was relatively high. There were no significant differences in the proportion between either demented subjects and nondemented subjects or early-onset dementia patients and late-onset dementia patients during the research period., Conclusion: We conclude that early-onset dementia is not rare and its clinical characteristics and causes are different from late-onset dementia., (Copyright (c) 2007 S.

- Abstract
Objective: Neuropsychiatric disturbances are common and burdensome symptoms of dementia. Assessment and measurement of neuropsychiatric disturbances are indispensable to the management of patients with dementia. Neuropsychiatric Inventory (NPI) is a comprehensive assessment tool that evaluates psychiatric symptoms in dementia. We translated the NPI-Caregiver Distress Scale part of NPI (NPI-D) and NPI-Brief Questionnaire Form (NPI-Q) into Japanese and examined their validity and reliability., Subjects and Methods: The subjects were 152 demented patients and the caregivers who lived with them. These patients consisted of 76 women and 76 men; their mean age was 73.9 +/- 7.8 (S.D.; range: 49 to 93) years. Their caregivers consisted of 46 men and 106 women; their mean age was 65.0 +/- 11.4 (S.D.; range: 35 to 90) years. The Mini-Mental State Examination (MMSE) was conducted with all patients and NPI-Q, NPI, NPI-D, and the Zarit caregiver burden interview (ZBI) were conducted with all caregivers. We examined validity of NPI-D by comparing its score with the MMSE and ZBI scores, and the validity of NPI-Q by comparing its score with the NPI and NPI-D scores. In order to evaluate test-retest reliability, NPI-D was re-adopted to 30 randomly selected caregivers by a different examiner one month later and NPI-Q was re-executed by 27 randomly selected caregivers one day later., Results: Total NPI-D score was significantly correlated with ZBI (rs = 0.59, p < 0.01). Test-retest reliability of NPI-D was adequate (ri = 0.47, p < 0.01). Total NPI-Q severity score and distress score were strongly correlated with NPI (r = 0.77, p < 0.01) and NPI-D (r = 0.80, p < 0.01) scores, respectively. Test-retest reliability of the scores of NPI-Q was acceptably high (the severity score; ri = 0.81, p < 0.01, the distress score; ri = 0.80, p < 0.01)., Conclusion: The Japanese version of NPI-D and NPI-Q demonstrated sufficient validity and reliability as well as the original version of them. These are useful tools for evaluating psychiatric symptoms in demented patients and their caregivers' distress attributable to these symptoms.

- Abstract
This study was designed to quantify the heterogeneity on cerebral blood flow single-photon emission tomography (SPET) images in frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD) using a three-dimensional fractal analysis. Twenty-one FTLD patients, 21 AD patients and 11 healthy controls underwent technetium-99m hexamethylpropylene amine oxime SPET scanning. Patients with FTLD and AD matched for sex, age and the severity of dementia as estimated with the Clinical Dementia Rating and were determined to be in the early stage of illness. We delineated the SPET images using a 35% cut-off and a 50% cut-off of the maximal voxel radioactivity and measured the number of voxels included in the contours of two different cut-offs. The fractal dimension (FD) was calculated by relating the logarithms of the cut-offs and the numbers of voxels, and it was defined as the heterogeneity of the cerebral perfusion. We divided the SPET images into two sets, anterior and posterior, with equal numbers of coronal SPET slices. We calculated total FD, anterior FD and posterior FD for total, anterior and posterior SPET images. Anterior FDs for FTLD and AD were 1.55 +/- 0.34 and 1.24 +/- 0.19 (P = 0.0002). The ratios of anterior to posterior FD for FTLD and AD were 1.81 +/- 0.41 and 1.32 +/- 0.14 (P < 0.0001). Use of the anterior FD and the ratio of anterior to posterior FD separated FTLD patients from AD patients and controls with a sensitivity of 85.7% and a specificity of 93.8%. Anterior FD and the ratio of anterior to posterior FD may be useful in distinguishing FTLD from AD.

- Abstract
Patients with frontotemporal lobar degeneration (FTLD) present a profound personality change, social misconduct, overeating, and stereotyped behavior. We examined the hypothesis that many of the behavioral symptoms of FTLD will respond to selective serotonin reuptake inhibitors (SSRIs). Sixteen FTLD patients were treated with an SSRI (fluvoxamine maleate) in an open 12-week trial. Treatment responses for stereotyped behavior and other neurobehavioral symptoms were evaluated by the Stereotypy Rating Inventory and the Neuropsychiatric Inventory. The behavioral symptoms, especially stereotyped behaviors of FTLD, significantly improved after treatment. Randomized, placebo- and other SSRI-controlled trials may improve available treatments., (Copyright 2004 S. Karger AG, Basel)

- Abstract
Background: Delusions constitute one of the most prominent psychiatric complications in Alzheimer's disease (AD). However, there is little consensus of the prevalence and associated factors for delusions in AD., Aims: To reveal the characteristics of delusions among Japanese patients with AD., Method: 112 consecutive patients with AD were recruited over a one year period and administered the Neuropsychiatric Inventory (NPI)., Results: Delusions were present in 53 patients (47.3%). Delusions of theft were the most common type of delusion (75.5% of patients with delusions), followed by misidentification delusions and delusions of suspicion. More hallucination, agitation, and female gender were found in the delusions group., Conclusions: The authors found a high frequency of delusions, particularly of delusions of theft and suggested that gender was associated with the expression of delusions in Japanese patients with AD., (Copyright 2003 John Wiley & Sons, Ltd.)

- Abstract
We report a 71-year-old woman showing rapidly progressive non-fluent aphasia and dementia accompanied by motor neuron disease (MND). There was no family history of dementia or motor neuron disease. There was 10 months history of dysarthria and dysphagia. On examination, she showed profound difficulty in articulation. Her comprehension was impaired in that she was unable to obey three-stage command. Her written language was also impaired with phonological spelling errors, syntactic errors, and perseveration. Neuroradiological investigations showed atrophic changes and hypoperfusion of left temporal and bilateral parietal region revealed by MRI and SPECT, respectively. Her subsequent decline was rapid. It might be likely that aphasia is much more common in dementia with bulbar MND than is currently recognized because bulbar palsy might mask the language disorder.

- Abstract
A many behavioral disturbances, Stereotypic behaviors are among the best discriminators of Frontotemporal Lobar Degeneration (FTLD). A recent preliminary report suggests many of the behavioral symptoms, including stereotypic behaviors in FTLD patients, respond to medication with selective serotonin re-uptake inhibitors. However, there is no scale that evaluates stereotypic behaviors comprehensively. To assess the wide range of stereotypic behaviors encountered in FTLD, we developed a new instrument, the Stereotypy Rating Inventory (SRI). The SRI assesses five distinctive stereotypic behavioral disturbances often seen in patients with FTLD: eating and cooking behaviors, roaming, speaking, movements, and daily rhythm. The SRI uses the same technique as the Neuropsychiatric Inventory (NPI) in that both the frequency and the severity of each behavior are determined. The studies reported here demonstrate the content and concurrent validity, as well as inter-rater and test-retest reliability, of the instrument. Scores of FTLD patients (n=26) on the SRI were much higher than those of patients with Alzheimer's disease (n=46), patients with vascular dementia (n=26), and normal control subjects (n=40). The SRI appears to be a useful instrument for detecting stereotypic behaviors and monitoring of therapies in FTLD patients.

- Abstract
Background: Delusions of theft (delusions involving the theft of possessions) are one of the most frequent neuropsychiatric manifestations of Alzheimer's disease (AD)., Objective: The current study investigated the presence and extent of such delusions before and after drug treatment in a group of AD patients, and the consequent effects on the burden of care on caregivers., Method: The study was an open-label cohort design. The delusions studied consisted only of those involving theft of possessions. Sixteen AD patients served as subjects in order to assess the efficacy of Risperidone administration, in the reduction or elimination of these delusions. The caregiver burden was evaluated using the Zarit Caregiver Burden Interview (ZBI) before the administration of Risperidone and 12 weeks after administration, for cases where delusions of theft were eliminated or reduced., Results: The burden of care on caregivers was significantly reduced (p < 0.001) through the elimination or reduction of delusions of theft., Conclusion: Delusions of theft are considered to be a major factor in increasing the burden of care, and the treatment of these, through appropriate drug therapy, is therefore of great importance in the continuation of satisfactory care in the home., (Copyright 2002 John Wiley & Sons, Ltd.)

- Abstract
Frontotemporal lobar degeneration is the most common form of cortical dementia occurring in the presenium after Alzheimer's disease. We analyzed two types of frontotemporal dementia (FTD) and semantic dementia (SD) selected from a consecutive series of outpatients based on neuropsychological symptoms, psychiatric symptoms and abnormal behavior. In our series of 134 patients with primary degenerative dementia, there were 16 cases of FTD and 6 cases of SD. Patients with subgroups of FTD and patients with SD were distinguishable only by the presence of aphasia in the latter group. They were not distinguishable from one another by other neuropsychological examinations, behavioral abnormalities or psychiatric symptoms assessed with the Neuropsychiatric Inventory., (Copyright 2001 S.

In the present study, we employed the questionnaire-type ADAS(cog) examination to accurately assess the severity of AD. Between five groups classified on the basis of ADAS(cog) score, significant differences were observed in parietal, lateral temporal and superior frontal rCBF. In addition, in parietal and lateral temporal regions, significant correlations were also observed between ADAS(cog) score and rCBF. In superior frontal rCBF, significant differences were noted only between group 5 (> or =40 ADAS(cog) points) and each of the other groups; there was no significant correlation between rCBF and ADAS(cog) score. Thus, we propose the following mechanism for blood flow kinetics associated with changed severity: In an early stage of AD, blood flow in the medial temporal cortex is impaired, and gradually involves the temporoparietal regions. While the medial temporal impairment of blood flow reaches a plateau, temporoparietal blood flow continues to be impaired well into a severe stage, at which point blood flow impairment in the frontal region is initiated., (Copyright 2001 S.

- Abstract
We investigated the neural substrate of the delusion of theft in patients with Alzheimer's disease (AD). Nine AD patients with only one type of delusion (delusions of theft) and nine age, cognitive function-matched AD patients without any type of delusions were selected from 334 consecutive outpatients of Ehime University Hospital. All subjects underwent (99m)Tc-HMPAO SPECT scanning, and SPECT images were analyzed by Statistical Parametric Mapping (SPM). AD patients with delusions of theft showed significant hypoperfusion in the right medial posterior parietal region compared to patients without delusions. Our data suggest that attention impairment or lack of awareness of illness caused by right parietal dysfunction might play a role in producing the delusion of theft.

- Abstract
Corticobasal degeneration(CBD) is a neurodegenerative disorder characterised clinically by apraxia, cortical sensory loss, alien limb, dementia, oculomotor abnormalities, dysarthria, postural instability, akinesia, rigidity, and pyramidal signs. Brain imaging may demonstrate greater abnormalities contralateral to the more affected side. We reported a case of corticobasal degeneration of which praxic impairments were improved by administration of amantadine. The patient was a 63-year-old right-handed woman. She showed marked dysfunction including rigidity, limb kinetic apraxia, cortical sensory loss, ideomotor apraxia, and dressing apraxia. A brain MRI scan revealed bilateral cortical atrophy centered in the postcentral gyrus, more pronounced in the left hemisphere than the right. A SPECT scan showed a decrease in blood flow in the temporo-parieto-occipital regions, more pronounced in the left hemisphere than the right. An EEG showed a diffuse slowness. L-dopa had no effect on the symptoms of rigidity, limb kinetic apraxia, cortical sensory loss, ideomotor apraxia, and dressing apraxia. By administration of amantadine, rigidity and cortical sensory loss did not improve, but some praxic impairments, such as dressing apraxia and ideomotor apraxia, and the EEG improved. Upon withdrawal of amantadine, the improved symptoms deteriorated. Amitriptyline did not improve the deteriorated symptoms. After amantadine was re-administered, the same praxic impairments and the EEG improved again. This suggested that administration of amantadine had some effect on certain praxic impairments and the EEG.

- Abstract
A 29-year-old female without alcoholism whose height and weight were 152 cm and 28 kg had complained of severe anorexia since about 10 years ago. The splenium of the corpus callosum showed symmetrically low-intensity area in T1 WI and high-intensity area in T2 WI on her brain MRI. These findings could be reversible by the recovery of her nutritional condition. The findings of neurological and neuropsychological examinations were normal. To our knowledge, this is the first case report of Marchiafava-Bignami disease caused by Anorexia Nervosa.

- Abstract
Objective: Examination of the utility of (99m)Tc-hexamethylpropylene amine oxide ((99m)Tc-HM-PAO) SPECT hippocampal image to diagnose early stages of Alzheimer's disease (AD) using semiquantitative analysis., Subjects: 10 early-stage AD patients and 8 normal sex-matched elderly controls., Setting: Outpatient division of the Ehime University Hospital., Method: We performed (99m)Tc-HM-PAO SPECT perfusion imaging in each subject. A semiquantitative method of assessing regional variation was used. The regions of interest for temporal regions were set at images parallel to the long axis of the hippocampal formation which were reconstructed at 30 degrees negative to the orbitomeatal line and those for other regions were set on ordinary transaxial images., Results: The regional cerebral blood flow ratio of the bilateral medial temporal lobe at the hippocampal image was significantly lower in the AD subjects than in the normally aged controls without any other differences in ordinary transaxial images., Conclusion: This study suggests that (99m)Tc-HM-PAO SPECT hippocampal images might be a helpful tool for the diagnosis of very-early-stage AD., (Copyright 2001 S.

- Abstract
Purpose: To determine whether the Short-Memory Questionnaire (SMQ) being administered by caregivers to patients with Alzheimer's disease (AD) is also valid when given to patients with vascular dementia (VaD)., Methods: Subjects were 58 patients with VaD, 26 patients with cerebrovascular disorders free of cognitive deficit (CVD) and 62 healthy controls. All subjects received the Mini-Mental State Examination (MMSE), and their primary caregivers (or family members with same household) received the SMQ., Results: In the VaD patients, the SMQ score was highly correlated with the MMSE score. When 39/40 was defined as a cutoff point based on the results of previous study, the SMQ properly classified 55 of the 58 VaD patients and 61 of the 62 controls, but only about half of the 26 CVD patients, as cases., Conclusion: The SMQ, a simple quantitative rating test for memory disturbance, is useful for the assessment and screening of VaD patients as well as AD patients, although careful attention should be paid to the assessment of CVD patients., (Copyright 2000 John Wiley & Sons, Ltd.)

- Abstract
Objective: To compare the validity of the Mini Mental State Examination (MMSE) and the Short-Memory Questionnaire (SMQ) as screening tests to detect dementia in the elderly general population., Subjects: Six hundred and sixty-two subjects and their informants from the elderly general population sample who had completed these tests., Setting: One rural community survey in Japan., Method: We used receiver-operating characteristic analysis to compare the performance of the MMSE and the SMQ with the clinical diagnosis of dementia according to DSM-III-R., Results: The areas under the receiver-operating characteristic curve of the MMSE and the SMQ were 0.980 (SE = 0.006) and 0.982 (SE = 0.008), respectively. This differed from chance to a highly significant degree for both the MMSE and the SMQ, but the difference between the two scales was not statistically significant., Conclusion: As screening tests to detect dementia in the elderly general population, the SMQ which is assessed by informants demonstrates a statistically significant discriminating ability as well as the MMSE., (Copyright 2000 S.

- Abstract
A study was performed to assess interrater reliability of the Japanese version of the Short-Memory Questionnaire (SMQ), which is an easily-administered, informant-based scale of cognitive function. The subjects were 18 consecutive patients with Alzheimer's disease who were outpatients of Department of Neuropsychiatry in Ehime University School of Medicine and their principal caregivers. One neuropsychiatrist (NP) administered the SMQ, and all sessions were videotaped. Then one nurse (Ns), one clinical psychologist (CP), one occupational therapist (OT), and one neurologist (NL) from another institution viewed the videotape and performed reassessments independently. Interrater reliability between the NP and Ns, CP, OT, or NL were all extremely good. Interrater reliability between the Ns and CP, between the Ns and OT, between the Ns and NL, between the CP and OT, between the CP and NL, and between the OT and NL were also extremely good. The SMQ is a convenient, quantitative scale, and in this study it showed good interrater reliability between personnel from different fields. Therefore, it is a very useful test for everyday medical consultations and for clinical research., (Copyright 2000 John Wiley & Sons, Ltd.)

- Abstract
Front-temporal dementia (FTD), advocated by Lund and Manchester groups, includes Pick type corresponding to the conventional frontal Pick's disease, motor-neuron type associated with neural symptoms, and frontal lobe degeneration type. In Japan, however, there have been few case reports of the frontal lobe degeneration type. Here we examined clinical characteristics and imaging findings of 2 cases of FTD frontal lobe degeneration type. Neurological examinations were normal. CT and MRI scans revealed no obvious frontal lobar atrophy, while HMPAO-SPECT scans demonstrated remarkable hypoperfusion in anterior hemisphere. Neuropsychological examination revealed frontal symptoms, including personality change, stereotypes, and disinhibition. These symptoms can not be distinguished from the cases of FTD Pick type, because those cases of FTD Pick type have obvious lobar atrophy.

- Abstract
Background and Purpose: The Short-Memory Questionnaire (SMQ) developed by Koss et al. is a standardized, validated reliable informant-based scale to assess everyday memory problems. In the previous study, we prepared its Japanese version and validated the reliability in assessing patients with Alzheimer Disease. In the present study, we examined the relations between the performance evaluated by the Japanese version of the SMQ combined with the Mini-Mental State Examination (MMSE) and demographic variables (age, sex, and education)., Subjects and Methods: Subjects were a total of 613 elderly healthy individuals living in the rural residency of Nakayama, Japan. They consisted of 287 males and 326 females and ranged from 65 to 94 years in age and from 0 to 16 years in education. The MMSE was conducted by neuropsychiatrists to assess the severity of cognitive impairment, and the SMQ was conducted by public health nurses, who asked a family member of each subject. The effects of age, sex and education on the MMSE and SMQ scores were analyzed by analysis of variance (ANOVA) using post-hoc Scheffé test., Results: The mean MMSE and SMQ scores (+/- SD) were 27.6 (+/- 2.5) and 44.5 (+/- 2.1), respectively. The post-hoc Scheffé test revealed significantly higher MMSE scores for individuals with 8 years or more in education than for those with less than 8 education years. Between males, no significant differences were observed in MMSE score; however, among females, significantly higher scores were noted in those aged 69 or younger than in those aged 70-74 or those aged 80 or older. Of individuals aged 80 or older, males showed significantly higher scores than females, whereas no significant differences were observed between sex in other age groups. As to the SMQ, higher scores were shown by persons with longer education years and by females than males., Conclusion: Low MMSE scores were related to low education level and older females. Low SMQ scores were not related to aging, but linked to low education level and males. Both the MMSE and SMQ, which can be easily administered, are affected by education years and sex. In addition, MMSE score depends on age. Therefore, careful consideration should be paid to age, education level and sex for future execution of the MMSE and SMQ.

- Abstract
Background and Purpose: Memory deficit is a common sign of Alzheimer's disease (AD), which appeared generally in the early stage of the disease. Therefore, evaluation of memory is important for management of patients and for clinical research of AD. The Short-Memory Questionnaire (SMQ), an easily administered, informant-based scale, which was developed by Koss et al. (1993), is a standardized, validated, and reliable tool to assess everyday memory problems. In the present study, we prepared a Japanese version of the SMQ and examined its reliability and validity in assessing AD patients., Subjects and Methods: The subjects consisted of 42 patients with NINCDS-ADRDA probable AD whose diagnosis was made on the basis of the results of comprehensive examinations including cranial CT/MRI and SPECT and age- and education-matched 53 healthy controls. Patients had no history of stroke, head injury, or any other prior neurological events. Patients and controls were between the ages of 51 and 90 years, and they had from 6 to 16 years education. The Japanese version of the SMQ was given to a family member by either neuropsychiatrist, public nurse or case worker. To evaluate test-retest reliability of the test, interview was repeated in 16 randomly selected patients by two different examiners (neuropsychiatrist and another) in two weeks interval. The Mini-Mental State Examination (MMSE) was used to assess the severity of cognitive impairment., Result: The test-retest reliability was acceptably high with intraclass correlation coefficients. There was a high correlation between scores of SMQ and MMSE. The SMQ had excellent specificity and sensitivity in discriminating patients from controls. Caregiver appraisals of memory deficits significantly correlated with generalized cognitive dysfunction., Conclusions: Similarly to the original version, the present Japanese version of the SMQ is a reliable and valid tool in assessing memory function in AD, which can be effectively used in clinical settings and epidemiologic studies to screen out persons with memory problems.
