Assessment of the functional competencies of patients with dementia is typically conducted in an indirect manner. Psychological tests of cognition or descriptions by relatives or other caregivers are often used to make judgments as to the patient's ability to adapt to the demands of the environment. However, these methods have built-in biases. The need for(More)
OBJECTIVE The authors evaluated the efficacy of a new cognitive rehabilitation program on memory and functional performance of mildly impaired Alzheimer disease (AD) patients receiving a cholinesterase inhibitor. METHODS Twenty-five participants in the Cognitive Rehabilitation (CR) condition participated in two 45-minute sessions twice per week for 24(More)
The areas of six bilateral brain segments in the right and left hemispheres, on a horizontal brain section, and the area of subdivisions of the corpus callosum, on a midsagittal brain section, were measured on magnetic resonance images obtained from 21 dyslexic and 29 control subjects. In the entire group, the frontal half of the horizontal brain section(More)
Mild cognitive impairment (MCI), an intermediate state between normal aging and dementia, is characterized by acquired cognitive deficits, without significant decline in functional activities of daily living. Studies conducted on MCI have introduced new concepts regarding the possible distinctions between normal and pathologic aging of the brain.(More)
Category fluency tasks are an important component of neuropsychological assessment, especially when evaluating for dementia syndromes. The growth in the number of Spanish-speaking elderly in the United States has increased the need for appropriate neuropsychological measures and normative data for this population. This study provides norms for English and(More)
Late-life depression is a major health problem and a significant cause of dysfunction that warrants closer evaluation and study. In contrast to younger depressed patients, most depressed older adults suffer more severe variants of the disorder, including significant cognitive impairments. These cognitive changes add to the severity of symptoms and(More)
Twenty subjects with mildly to moderately severe Alzheimer disease (AD) and 14 normal elderly control subjects were studied using [18F]fluorodeoxyglucose and positron emission tomography (PET) to investigate regional cerebral glucose metabolism during both a resting state and a behavioral activation state, utilizing a reading memory task (RMT). The RMT(More)
BACKGROUND Mild cognitive impairment (MCI) has been defined in several ways. OBJECTIVE To determine the 1-year outcomes of MCI by different definitions at the population level. DESIGN Inception cohort with 1-year follow-up. Participants were classified as having MCI using the following definitions operationalized for this study: amnestic MCI by Mayo(More)
Impairment in delayed recall has traditionally been considered a hallmark feature of Alzheimer's disease (AD). However, vulnerability to semantic interference may reflect early manifestations of the disorder. In this study, 26 mildly demented AD patients (mild AD), 53 patients with mild cognitive impairment without dementia (MCI), and 53 normal(More)
