Mental and Physical Self-Awareness of Alzheimer Patients: Decreased Awareness of Amnesia and Increased Fear of Falling Compared to Views of Families: The Tajiri and Wakuya Projects.

INTRODUCTION: The purpose of this study is to examine self-awareness of patients with Alzheimer disease (AD) regarding forgetfulness and physical status, with the goal of further psychological understanding of these patients. METHODS: The 255 subjects included 33 healthy volunteers and 48 patients with mild cognitive impairment who were elderly community residents selected from the 2017 Wakuya Project and 174 consecutive outpatients with AD at the Tajiri Clinic. Test data were selected from a pooled database. Results from the Mini-Mental State Examination, Clinical Dementia Rating (CDR), Short Falls Efficacy Scale International (FES), and Everyday Memory Checklist (EMC) were used in the study. FES and EMC data were also obtained from family members for comparison. RESULTS: EMC scores in the AD groups (mild to moderate and moderate to severe) were significantly higher (more complaining memory impairment) than those in the CDR 0 (healthy) group and significantly lower (less self-awareness for memory impairment) than the corresponding EMC scores of families of the subjects. In contrast, FES scores of the AD groups did not differ significantly from those of the CDR 0 group, and these scores were higher (more fear of falling) than those of family members. Additionally, family-FES scores of the AD groups were higher than those of the CDR 0 and 0.5 groups. CONCLUSION: The results showed an evidence of the heterogeneity of awareness, an emotional response (concern or fear, FES), and a cognitive appraisal of function (EMC). These may be explained whereby awareness of/fear of falling increases with AD due to a preserved emotional awareness, whereas awareness of cognitive impairment is impaired due to memory deficits.

Disturbed social recognition and impaired risk judgement in older residents with mild cognitive impairment after the Great East Japan Earthquake of 2011: the Tome Project.

AIM: After the Great East Japan Earthquake of 2011, we investigated the safety of residents in the affected communities. Most of the people requiring help were elderly and had previously been assessed as Clinical Dementia Rating (CDR) 0.5 (i.e. as having mild cognitive impairment (MCI)). We examined how well they understood the television news and whether they could make appropriate decisions. METHODS: This community-based study of dementia and difficulties following a disaster started in Tome, northern Japan. The subjects were 188 randomly selected older residents who underwent CDR, blood tests, magnetic resonance imaging, and cognitive tests, including an original visual risk cognition task. They were shown NHK news broadcasts from the day of the earthquake to determine whether they could understand the content. RESULTS: Neither the CDR 0 (healthy) nor the CDR 0.5 (MCI) subjects fully understood the television news. Some subjects did not recognize the danger of aftershocks and engaged in risky behaviour. CDR 0.5 subjects who exhibited such behaviour scored lower on the visual risk cognition task. CONCLUSIONS: It is noteworthy that television news is difficult to understand, even for healthy older adults. We found that MCI subjects had particular difficulties due to the disaster and suggest that risk cognition could be evaluated using visually presented materials.

Falling of older adults with cognitive impairment: a new home environment evaluation chart and a preliminary examination in the Wakuya Project.

It is important to evaluate the home environment because most fractures in older adults are caused by falls indoors. However, previous studies have not separated individual abilities from environments. Also, the interrelationship between falls, cognitive function, and home environments has not been clarified. Objectives: The purpose of this study was to develop an evaluation method specific to the home environment and examine the effects of environment and cognitive impairment on falls. Methods: This was a case-control study analyzing 95 older adults living in the community. A Visiting Checklist for the Home Environment (VICHe) was developed and examined for reliability and validity. Inter-rater reliability (IRR) was examined by determining Cohen's kappa and the intra-class correlation coefficient. Guttman's split-half method was used for internal consistency, and Cronbach's alpha coefficient was obtained. Criterion-related validity was confirmed by Spearman's rank correlation coefficient with the Fall Risk Index's (FRI) total score of the environmental factor items. As a preliminary study, trends in the number of falls by cognitive function and home environment were examined. Results: The VICHe obtained validity, but the IRR was inadequate. In contrast, the version that focused on the on-floor environment (VICHe-OFI) showed IRR for all items and validity through correlations with the FRI. The number of fallers increased in the cognitive impairment group when the home environment was bad. Conclusions: Reliability and validity of the VICHe-OFI were obtained. Preliminary examination using this scale indicates that falls in the home of the elderly may be more affected by the home environment as cognitive function declines.

A avaliação do ambiente doméstico é importante pois a maioria das fraturas em idosos é causada por quedas dentro de casa. No entanto, estudos anteriores não separaram as habilidades individuais dos ambientes. Além disso, a inter-relação entre quedas, função cognitiva e ambientes domésticos não foi esclarecida. Objetivo: O objetivo foi desenvolver um método de avaliação específico para o ambiente doméstico e examinar os efeitos do ambiente e do comprometimento cognitivo nas quedas. Métodos: Este estudo foi um estudo de caso-controle analisando 95 idosos residentes na comunidade. Uma Lista de Verificação de Visitas para o Ambiente Doméstico (Visiting Checklist for Home Environment ­ VICHe) foi desenvolvida e examinada quanto à confiabilidade e validade. A confiabilidade entre avaliadores (CEA) foi examinada pela determinação do kappa de Cohen e do coeficiente de correlação intraclasse. O método split-half de Guttman foi usado para consistência interna e foi obtido o coeficiente alfa de Cronbach. A validade de critério foi confirmada pelo coeficiente de correlação de Spearman com a pontuação total da escala de risco de queda (ERQ) dos itens do fator ambiental. Como um estudo preliminar, foram examinadas as tendências no número de quedas por função cognitiva e ambiente doméstico. Resultados: O VICHe obteve validade, mas a CEA foi inadequada. Por outro lado, a versão que enfocou o ambiente "no chão" (VICHe-OFI) apresentou CEA para todos os itens e validade por meio de correlações com a ERQ. O número de quedas aumentou no grupo com comprometimento cognitivo quando o ambiente doméstico era ruim. Conclusões: Obteve-se confiabilidade e validade do VICHe-OFI. O exame preliminar com essa escala indica que as quedas do idoso no domicílio podem ser mais afetadas pelo ambiente doméstico à medida que a função cognitiva diminui.

Disturbed medication management in older adults with good cognitive health and mild cognitive impairment associated with semantic memory impairment: The Wakuya Project.

AIM: For older adults with mild cognitive impairment or mild dementia, maintaining daily lives at home is also ideal for quality of life. However, they have serious problems with medication management. Although the Dementia Assessment Sheet in community-based integrated care system-21 items and the regimen comprehension scale are assessment scales for medication, there have been no reports evaluating both semantic memory and actual performance. METHODS: A total of 180 older adults aged ≥75 years were entered in the Wakuya Project. They underwent the Clinical Dementia Rating, with two original tests: (i) the original semantic memory task for taking medication including the Dementia Assessment Sheet in community-based integrated care system-21 items; and (ii) the actual performance task related to medication including regimen comprehension scale. Non-demented participants were classified into two groups based on reports from their families; that is, a good management group (n = 66) and a poor management group (n = 42), and the two original tests were analyzed as explanatory variables. RESULTS: There were no differences between the two groups for the actual performance task related to medication including regimen comprehension scale. The success rates for the actual performance task related to medication including regimen comprehension scale (good management group/poor management group) were: regimen comprehension scale 40.9/23.8, One-Day Calendar 93.9/90.5, Medicine Chest 36.4/23.8 and Sequential Behavior Task 66.7/66.7, respectively. In the original semantic memory task for taking medication including the Dementia Assessment Sheet in community-based integrated care system-21 items, logistic regression analysis showed that only the mechanism of action remained (B -2.38, SE 1.10, Wald 4.69, P-value = 0.03, OR 0.09, 95%CI 0.01-0.80). CONCLUSION: Our results suggest that disruption of medicine management might also be associated with drug semantic memory impairment between the two groups, with no difference in general cognitive and executive functions.

Lower extremities task of pressing an "accelerator" or a "brake": association with traffic accidents in older drivers - a preliminary study.

Traffic accidents by older drivers are a social urgent problem. The National Police Agency (NPA) in Japan has institutionalized the Cognitive Function Test (NPA test) for renewal of a driver's license for older adults. However, driving ability cannot be simply evaluated by usual cognitive tests on the desk. Objective: It is important to add an on-road test, but if not possible, we can use simulators. Before doing simulators, it is important to use the right foot to control the accelerator and brake pedals. We applied the Posner paradigm (visual attention test) for lower extremities. Methods: The participants were older adults. They and their families had anxiety about their driving. The 66 participants (44 men and 22 women) were divided into groups with and without experience of a traffic accident, and the following tests were examined: General cognitive and executive function tests, the NPA test, and an original Lower Extremity Reaction Test. Each participant was asked to press the "brake" or "accelerator" pedal by the right foot as quickly as possible in response to a traffic situation shown on the screen. Results: Compared to participants with favorable reactions to the Lower Extremity Reaction Test, those with poor reaction time tended to have more traffic accidents (OR=6.82), rather than the result of the NPA test. Conclusions: The results suggest that the probability of having a traffic accident can be better evaluated using the Lower Extremity Reaction Test.

Os acidentes de trânsito por motoristas idosos são um problema social urgente. A Agência Nacional de Polícia (National Police Agency ­ NPA) no Japão institucionalizou o Teste de Função Cognitiva (teste NPA) para renovação de carteira de motorista para idosos. No entanto, a capacidade de dirigir não pode ser avaliada simplesmente por testes cognitivos usuais escritos. Objetivo: É importante adicionar um teste em estrada, mas se não for possível, simuladores podem ser utilizados. Antes de fazer simulações, é importante usar o pé direito para controlar os pedais do acelerador e do freio. Aplicamos o paradigma de Posner (teste de atenção visual) para extremidades inferiores. Métodos: Os participantes eram idosos. Eles e suas famílias tinham ansiedade sobre a condução de veículos. Os 66 participantes (44 homens e 22 mulheres) foram divididos em grupos com e sem experiência de acidente de trânsito, e foram examinados os seguintes testes: testes cognitivos gerais e funções executivas, o teste NPA, e um Teste de Reação de Extremidade Inferior original. Cada participante foi solicitado a pressionar o pedal de "freio" ou "acelerador" com o pé direito o mais rápido possível em resposta a uma situação de trânsito mostrada na tela. Resultados: Comparados aos participantes com reações favoráveis ao Teste de Reação de Extremidade Inferior, aqueles com tempo de reação ruim tenderam a ter mais acidentes de trânsito (OR=6,82) do que o resultado do teste NPA. Conclusões: s resultados sugerem que a probabilidade de ocorrência de um acidente de trânsito pode ser melhor avaliada por meio do Teste de Reação da Extremidade Inferior.

The Changes in the 18F FDG Metabolism in the Muscles by the Use of Cuboid Support Insoles.

Healthy men aged 55,39, 23.45 years were administered 18F-fluorodeoxyglucose (18F-FDG) after fasting for over 5 h; then, a 30-min self-paced walking (6-min walk and 2-min rest + 6-min walk and 2-min rest + 6-min walk and 2-min rest + 6-min walk) session was performed. While walking, the same athletic shoes were used, same with walking supports, flat insoles, and cuboid support insoles (BMZ Inc., Tokyo, Japan). The walking test was performed with eye open. The examination was performed over 30 days apart. 18F-FDG accumulation within the gastrocnemius muscle was higher, the walking speed was improved. These results suggest that the use of cuboid support insoles may improve the cadence of the lower leg muscles.

Difficulties with Workplace Support for a Patient with Frontotemporal Dementia: A Case Report.

A 59-year-old, right-handed woman made many mistakes in her job in a pharmacy, despite having considerable experience working in this setting. She had a can-do attitude, but also showed no sign of remorse when she failed. Other staff grew impatient with her and she was diagnosed with frontotemporal dementia based on clinical and brain imaging findings. After diagnosis, other staff understood that the disease was the cause of her difficulties, and her work tasks and hours were changed to fit with her stereotypical behavior. This support in the workplace made it possible for her to continue her job.

Self-Reported Cognitive Decline Based on the Ascertain Dementia 8 Questionnaire May Be Effective for Detecting Mild Cognitive Impairment and Dementia in the Community: The Wakuya Project.

INTRODUCTION: To assess cognitive impairment, self-awareness is an important issue. The Ascertain Dementia 8 questionnaire (AD8) is a brief observation checklist for detecting mild cognitive impairment (MCI) and dementia. After analyzing the reliability and validity of a self-reported Japanese version of the AD8 (AD8-J), we compared self- and informant-reported versions of the AD8-J. METHODS: A total of 93 community residents aged 75 years or older living in Wakuya, Northern Japan, agreed to participate in this study; 35 were rated as Clinical Dementia Rating (CDR) 0 (healthy), 46 as CDR 0.5 (defined herein as MCI), and 12 as CDR 1 or above (dementia, confirmed by the DSM-IV). We examined the reliability and validity using a receiver operating characteristic (ROC) curve. We analyzed the differences between self-reported and informant-reported AD8-J using a repeated measures ANOVA. RESULTS: The self-reported AD8-J showed a satisfactory reliability (i.e., Cronbach coefficient, α = 0.71; Guttman split half method coefficient = 0.60). For CDR 0 vs. CDR 0.5 or above, the area under the ROC curve was 0.74 and the cutoff score was 1/2, with a sensitivity of 70.7% and a specificity of 65.7%. Analysis of the subscores of AD8 suggested that, from the early stage of dementia, the subjects showed a subjective decline in memory and interest in hobbies/activities, as well as problems with judgment. CONCLUSION: It is suggested that the self-reported AD8-J was effective in detecting MCI and dementia. We could use it for detecting MCI and dementia, including in those living alone, in the primary health checkup.

Decreased Time on the Nondominant One-Leg Standing Test Associated with Repeated Falls in Older Residents with Healthy Aging, Mild Cognitive Impairment, and Dementia: The Wakuya Project.

INTRODUCTION: The aim of this study is to clarify the association between repeated falls and the dominant/nondominant side in the open-eyed one-leg standing (OLS) test among people who are healthy or have mild cognitive impairment (MCI) or dementia in a community setting. We recruited 180 participants from 39 areas in the town of Wakuya. METHODS: This is a cross-sectional study. Participants were classified into 3 Clinical Dementia Rating (CDR) groups, i.e., CDR 0 (healthy, n = 71), CDR 0.5 (MCI, n = 85), and CDR 1+ (n = 23), and they were investigated for motor function (grip strength, 6-m normal gait speed, timed up and go test, and OLS test) and falls during the past year. RESULTS: Subjects with a CDR of 0.5 had higher rates of single and repeated falls (13.0 and 23.4%, respectively) than the CDR 0 group (12.1 and 4.5%, respectively), as did those in CDR 1+ group (15.0 and 30.0%). For the CDR 0.5 group, the frequency of falls was negatively (biologically meaningful direction) correlated with the left OLS time. No significant correlations with falls were found for other motor function tests. Another analysis separating the CDR 0.5 group into 2 subgroups (repeated falls vs. no or a single fall) also showed that the left OLS time was lower in subjects with repeated falls. CONCLUSION: People with MCI who had fallen repeatedly in the year before the assessment had a significantly lower left OLS time compared to those who had not fallen or had had 1 fall with MCI. None of the other physical measures were associated with past repeat falls including OLS on the dominant right side. No such findings were noted in the CDR 0 and CDR 0+ groups.

Word Processing Is Faster than Picture Processing in Alzheimer's Disease.

OBJECTIVE: Alzheimer's disease (AD) is characterized by a slow progressive impairment of episodic memory. Many studies have shown that AD exhibits deterioration of semantic memory during the course of disease progression. We previously reported that AD patients exhibited severe access disorders in the semantic memory system, using the Momentary Presentation Task (20 or 300 ms). In this study, we studied access disorder in patients with AD by the use of object difference (pictures vs words) methods. METHODS: 56 patients with probable AD (NINCDS-ADRDA, mean age 79.0 years) and 11 healthy controls (HC) (mean age 67.0 years) were studied. Ten pictures and 10 corresponding Japanese Hiragana words were presented arbitrarily for 20 and 300 ms on the monitor screen which were correctly named at the usual confrontation setting (i.e., semantic memory preserved). They were asked to name the pictures or to read the words or nonsense syllables aloud. RESULTS: The AD group showed significantly lower scores than the HC group, especially for the 20 ms condition. For the type of stimuli, the AD patients had better performances for words > pictures > nonsense syllables, although no differences for the HC group. The effect of AD severity was noted, moderate > severe stage. CONCLUSIONS: Our results suggested that the processing speed in AD patients may have reduced, even if the semantic memory were preserved. These data indicated that the difference in the processing speeds by the type of stimuli (pictures, words, and nonsense syllables) may be a character of AD patients.

Monitoring of drug treatment and psychosocial intervention with SPECT in Alzheimer patients Implications for neurologically appropriate psychosocial interventions. An observational study. The Osaki-Tajiri Project.

We previously examined cerebral blood flow (CBF) with single-photon emission computed tomography (SPECT) in Alzheimer's disease (AD) with reference to drug treatment (donepezil) and psychosocial intervention. OBJECTIVE: The aim is to provide "brain-based" evidence for psychosocial interventions using SPECT. METHODS: The participants were 27 consecutive outpatients with AD who received the drug and psychosocial intervention, and SPECT three times (baseline, pre-/post-intervention) at 6 month-intervals. The significance level of changes in CBF (Z score) and the extent of significantly changed areas, calculated with the eZIS system, were used as monitoring parameters. The participants were classified into three groups: improve (post-intervention CBF increased), worsening (progressive decline), and no change. RESULTS: Six, 8, and 13 patients were classified as improve, worsening, and no change, respectively. All subjects in the improve group showed improvement in cognitive test scores for the MMSE and/or the CGI scores associated with the brain area with a CBF increase (right parietal lobe), suggesting appropriate psychosocial intervention (visuospatial intervention). CONCLUSION: These results suggest that monitoring of CBF with the eZIS system may be clinically applicable for monitoring of drug treatment and psychosocial intervention in AD patients.

Nós examinamos previamente o fluxo sanguíneo cerebral (FSC) com tomografia computadorizada de emissão de fóton único (SPECT) na doença de Alzheimer (DA) com referência ao tratamento medicamentoso (donepezila) e intervenção psicossocial. OBJETIVO: Fornecer evidências "baseadas no cérebro" para intervenções psicossociais usando o SPECT. MÉTODOS: Os participantes foram 27 pacientes ambulatoriais consecutivos com DA que receberam a droga e intervenção psicossocial, e SPECT por três vezes (basal, pré/pós-intervenção) em intervalos de seis meses. O nível de significância das mudanças no FSC (escore Z) e a extensão das áreas significativamente alteradas calculadas com o sistema eZIS foram utilizados como parâmetros de monitoramento. Os participantes foram classificados em três grupos: melhora (FSC pós-intervenção aumentada), piora (declínio progressivo) e nenhuma mudança. RESULTADOS: Seis, oito e 13 pacientes foram classificados como melhora, piora e sem alteração, respectivamente. Todos no grupo melhora mostraram aumento dos escores no MEEM e/ou nos escores do CGI associados à área do cérebro com aumento do FSC (lobo parietal direito), sugerindo intervenção psicossocial apropriada (intervenção visoespacial). CONCLUSÃO: Estes resultados sugerem que o monitoramento do FSC com o sistema eZIS pode ser clinicamente aplicável para o monitoramento do tratamento medicamentoso e intervenção psicossocial em pacientes com DA.

Fear of Falling and Cognitive Impairments in Elderly People with Hip Fractures.

BACKGROUND/AIM: The purpose of this study was to investigate the estimated prevalence of dementia and the relationship between cognitive impairment and fear of falling in patients with hip fractures. METHODS: Analysis 1 included 100 patients with hip fractures. Analysis 2 included a subgroup of subjects with ≥75 years of functional independence: 46 patients with hip fractures and 46 control subjects without hip fractures, and presence or absence of dementia. We used an informant-rated questionnaire including the AD8 for screening for dementia, the Barthel Index for assessing activities of daily living, and the Short Falls Efficacy Scale-International (FES-I) for assessing fear of falling. RESULTS: The estimated prevalence of dementia was 66% in patients with hip fractures. There were significant fracture and dementia effects, with significant covariate effects of age and gender on the Short FES-I scores. CONCLUSION: Our results suggested that more than two-thirds of patients with hip fractures had dementia. Fear of falling may reflect not only physical functions but also cognitive impairments.

Neuroepidemiologic and Neurobehavioral Characteristics of Motoric Cognitive Risk Syndrome in an Old-Old Population: The Kurihara Project.

BACKGROUND: Recently, the concept of motoric cognitive risk (MCR) syndrome was proposed, where slow gait is considered a risk factor for conversion to dementia. AIM: To retrospectively investigate the characteristics of MCR among a population aged 75+ years, focusing on the aspects of epidemiology and neurobehavioral characteristics. METHOD: The participants were 590 residents aged 75+ years living in Kurihara who underwent MRI and neurobehavioral assessments including walking velocity. The prevalence of MCR and conversion to dementia (AD8 Dementia Screening Interview cutoff 2/8), together with the neurobehavioral characteristics of the MCR group, were analyzed. RESULTS: The prevalence was 11.1%, and the conversion ratio in the MCR group was higher than that in the non-MCR group (OR = 1.38). The MCR group had lower scores on the executive function test as well as gait velocity. CONCLUSIONS: The MCR syndrome increases the rate of conversion to dementia, and both slow gait and lower scores in executive tests, which are 'frontal-based' functions, are predictive of higher rates of conversion to dementia.
