BACKGROUND: Few studies have investigated the impact of the community environment, as distinct from area deprivation, on cognition in later life. This study explores cross-sectional associations between cognitive impairment and dementia and environmental features at the community level in older people. METHOD: The postcodes of the 2,424 participants in the year-10 interview of the Cognitive Function and Ageing Study in England were mapped into small area level geographical units (Lower-layer Super Output Areas) and linked to environmental data in government statistics...

INTRODUCTION: As drug development research efforts move toward studying patients earlier in the course of Alzheimer's disease (AD), it is important to incorporate the patient's perspective into measurement of outcomes. METHODS: This article summarizes the qualitative work of the Patient-Reported Outcome Consortium's Cognition Working Group in the development of a new self-reported outcome measure in persons with mild cognitive impairment (MCI) due to suspected AD, herein referred to as MCI...

OBJECTIVES: To study the temporal association between psychotic symptoms with cognitive decline and incident dementia. DESIGN: Population-based prospective cohort study. SETTING: General population in England and Wales. PARTICIPANTS: A subsample of 2,025 participants of the Medical Research Council Cognitive Function and Ageing Study, representing a study sample of 11,916 nondemented adults age 65 years or older.

Education and lifestyle factors linked with complex mental activity are thought to affect the progression of cognitive decline. Collectively, these factors can be combined to create a cognitive reserve or cognitive lifestyle score. This study tested the association between cognitive lifestyle score and cognitive change in a population-based cohort of older persons from five sites across England and Wales. Data came from 13,004 participants of the Medical Research Council Cognitive Function and Ageing Study who were aged 65 years and over...

An active cognitive lifestyle has been linked to dementia incidence and survival, but the separate and combined effects of its subcomponents are not clear. Data were derived from the Medical Research Council Cognitive Function and Ageing Study, a population-based study of 13,004 individuals in England and Wales first interviewed in 1991-1992 and followed over a 10-year period for dementia incidence and 12 years for mortality. A Cognitive Lifestyle Score (CLS), defined as a composite of cognitive activity including education, occupational complexity, and social engagement, was available for 12,600 individuals in 3 stages of life...

CONTEXT: Subjective memory impairment (SMI) is receiving increasing attention as a pre-mild cognitive impairment (MCI) condition in the course of the clinical manifestation of Alzheimer disease (AD). OBJECTIVES: To determine the risk for conversion to any dementia, dementia in AD, or vascular dementia by SMI, graded by the level of SMI-related worry and by the temporal association of SMI and subsequent MCI. DESIGN: Longitudinal cohort study with follow-up examinations at 1(1/2) and 3 years after baseline...
