简要总结
Life expectancy in Brazil has increased markedly over the last 30 years. Hence, age-related disorders, such as Alzheimer's disease (AD), warrant special attention due to their high prevalence in the elderly. Pharmacologic treatment of AD is based on cholinesterase inhibitors (ChEI) and memantine, leading to modest clinical benefits both in the short and long-term.
However, clinical response is heterogeneous and needs further investigation. Objective: To investigate the rate of response to ChEI in AD after three months of treatment. Methods: Patients with mild or moderate dementia due to probable AD or to AD associated with cerebrovascular disease were included in the study.
详细描述
The subjects were assessed at baseline and again after three months of ChEI treatment. Subjects were submitted to the Mini-Mental State Examination (MMSE), Mattis Dementia Rating Scale, Katz Basic Activities of Daily Living, Pfeffer Functional Activities Questionnaire, Neuropsychiatric Inventory and Cornell Scale for Depression in Dementia. Good response was defined by a gain of ≥2 points on the MMSE after three months of treatment in relation to baseline.

结局指标
主要结局
Cognitive Response After Three Months of Treatment With ChEI in Mild and Moderate Alzheimer's Disease
时间窗: three months
Patients presented mild or moderate dementia according to the Clinical Dementia Rating (CDR). None of the individuals had been treated with Cholinesterase inhibitors (ChEI) or memantine before study entry. Donepezil, galantamine or rivastigmine were prescribed to the patients according to the clinicians' preferences. All participants were evaluated by one board certified geriatrician (LFJRM) at baseline and after 3 months of treatment, as part of an ongoing 12-month responder analysis study of ChEI in Alzheimer's Disease. The main domain examined and the evaluation tools was cognition and Mini-Mental State Examination- MMSE, respectively. MMSE scores range from 0 to 30, while the greater value is associated with a better cognition state. An increase of 2 or more points in MMSE was considered as response.
