Demographic information, education, previous occupations, income, marital status, religion, medical history, medications, family history, health behaviors, and functional status were obtained through questionnaires. Depression was screened with the Geriatric Depression Scale, and anxiety was assessed using the Beck Anxiety Inventory. The standard neurological physical examination was adapted from the Unified Parkinson’s Disease Rating Scale. The evaluation assessed the participant’s memory, coherence and focus of responses, repetitiveness, and language. The neurologist also assessed each participant for abnormal behaviors, fluctuation in cognition, history of sleep disturbance, and visual/auditory hallucinations. The neurologist assigned a Hachinski Ischemic Score (HIS) and the Clinical Dementia Rating (CDR) and provided a clinical impression of the presence or absence of dementia. Global cognitive status, memory, attention, executive function, visuospatial construction, and language were measured. When possible, informants were interviewed to ascertain whether they noted any cognitive changes in the participant and to assess the accuracy of the participant’s responses. Anthropometrics, blood pressure, grip strength, and peak flow were measured. A fasting blood sample was obtained.
