Anosognosia is one of the major problems in the treatment and care of Alzheimer's disease (AD) patients. The aim of the study was to determine the patient characteristics, psychiatric symptoms, and cognitive deficits associated with anosognosia, because these are currently poorly understood. Eighty-four patients who met the National Institute of(More)
The clock drawing test (CDT) is a useful tool for screening cognitive impairment. Previous neuropsychological studies have revealed that CDT performance requires several cognitive functions including semantic memory, visuospatial function and executive function. However, the neural substrates involved remain to be elucidated. The aim of the present study(More)
AIM To investigate relationships among burnout, coping style and personality. METHODS Seventy-two professional caregivers working at nursing homes in Japan were assessed using the Maslach Burnout Inventory (MBI), NEO Five-Factor Inventory (NEO-FFI), 30-item General Health Questionnaire (GHQ) and Coping Inventory for Stressful Situation (CISS). RESULTS(More)
BACKGROUND The aim of this study was to identify the brain regions associated with the severity of delusions in individuals with Alzheimer's disease (AD) using single-photon emission computed tomography. METHODS Thirty-five AD patients participated in this study. Multiple regression analysis was performed to identify a linear correlation between the(More)
"δ", a latent variable constructed from cognitive performance and functional status measures, can accurately diagnose dementia. The minimal assessment needed is unknown. We have constructed a δ homolog, "dTEXAS", from Telephone Executive Assessment Scale (TEXAS) items, and validated it in a convenience sample of Japanese persons (n = 176). dTEXAS scores(More)
The aim of this study was to identify brain regions associated with performance on various measures of the clock drawing test (CDT) using magnetic resonance imaging (MRI).We recruited 48 participants (four healthy, eight with mild cognitive impairment and 36 with Alzheimer's disease). Multiple regression analyses identified relationships between each CDT(More)
OBJECTIVE "δ", a latent variable constructed from batteries that contain both cognitive and functional status measures, can accurately diagnose dementia relative to expert clinicians. The minimal assessment needed is unknown. METHODS We validated 2 δ homologs in a convenience sample of elderly Japanese persons with normal cognition (NC), mild cognitive(More)
The latent variable "δ", can accurately diagnose dementia. Its generalizability across populations is unknown. We constructed a δ homolog ("dT2J") in data collected by the Texas Alzheimer's Research and Care Consortium (TARCC). From this, we calculated a composite d-score "d". We then tested d's generalizability across random subsets of TARCC participants(More)
BACKGROUND The aim of the study was to develop the Japanese versions of Executive Interview (J-EXIT25) and Executive Clock Drawing Task (J-CLOX) and to evaluate the aspects of executive function that these two tests will be examining. METHODS The concurrent validity and reliability of J-EXIT25 and J-CLOX were first examined in all participants (n = 201).(More)
