OBJECTIVES (1) To investigate the prevalence and characteristics of agitation in patients with Alzheimer's disease (AD) and other forms of dementia; (2) to explore the association between agitation and other clinical variables, including disease severity, functional impairment and other neuropsychiatric symptoms, and (3) to determine the predictors of(More)
BACKGROUND Instrumental activities of daily living (IADL) depend on executive planning and procedural memory mediated by the frontal lobes. Planning and judgment are involved in clock drawing. Neuropsychiatric symptoms are also mediated by frontal lobes, and a relationship between ADL, clock drawing and neuropsychiatric symptoms was hypothesized. (More)
OBJECTIVE To investigate an association between endogenous estradiol (E(2)) levels and cognition and behavior in elderly individuals. PATIENTS We studied 135 community-based men and women aged 52 to 85 years in urban Bangkok, Thailand; 72 had dementia and 63 did not. MATERIALS AND METHODS Dementia was diagnosed using Diagnostic and Statistical Manual of(More)
BACKGROUND Activities of daily living (ADL) vary across cultures, and measure of ADL needs to be specific to the population under study. We developed an ADL measure for Thai elderly with dementia and investigated the reliability and validity of this instrument. MATERIALS AND METHODS Item construction was accomplished with a panel of neurologists and a(More)
The platelet amyloid precursor protein (APP) ratio has recently been shown to be a promising diagnostic marker for Alzheimer's disease (AD). To evaluate its usefulness in Thai patients, platelet APP was analyzed by immunoblotting. The APP ratio was calculated as the ratio of the combined band density of the 120-kD and 130-kD isoforms compared to that of the(More)
BACKGROUND In Thailand, family caregivers have an important role in delivering care to patients with dementia. Most patients with dementia in Thailand and also in Western societies live in the community. Training caregivers may improve care of dementia patients. OBJECTIVE We performed a treatment study of a six-month caregiver intervention with group(More)
Coordination and harmonization of efforts between five major research consortia on Alzheimer's disease may increase our understanding of this condition and improve our therapeutic approaches. Specific opportunities include a registry for families with early onset dementia, a study registry, minimal data sets, validation of assessment tools and outcomes,(More)
The Neuropsychiatric Inventory (NPI) was introduced in 1994 and has since become a standard instrument for clinical trials and other types of behavioral research in dementing disorders. Its reliability and validity have been confirmed. The NPI was the subject of a workshop in Asia in conjunction with the International Workgroup on Dementia Drug Guidelines(More)
BACKGROUND The 'Asia-Pacific Expert Panel (APEX) for donepezil 23 mg' met in November 2015 to review evidence for the recently approved high dose of donepezil and to provide recommendations to help physicians in Asia make informed clinical decisions about using donepezil 23 mg in patients with moderate-to-severe Alzheimer's disease (AD). SUMMARY In a(More)
BACKGROUND A strong inverse relationship of functional limitation and socioeconomic status has been established in western ageing society. Functional limitation can be related to chronic diseases, disuse, cognitive decline, and ageing. Among chronic diseases in the Thai population, cerebrovascular diseases, diabetes, and arthritis are common. These factors(More)
