Abstract
INTRODUCTION
This study aimed to determine the associations between parkinsonism and Parkinson's disease (PD) with cognitive impairment and dementia in a multi-country cohort in Latin America, using data from the 10/66 Dementia Research Group.
METHODS
This population-based prospective cohort study was conducted in six Latin American countries, including 11,321 participants 65 years of age or older living in urban and rural areas.
RESULTS
At baseline, the prevalence of cognitive impairment in people with parkinsonism and PD was 33% and 26%, respectively. Parkinsonism (odds ratio [OR] 2.2 [95% confidence interval [CI] 1.9–2.6] and PD (OR 1.9 [95% CI 1.4–2.4]) were individually associated with baseline cognitive impairment and incident dementia. The pooled sub-hazard ratios for dementia in fixed-effect meta-analysis were 1.5 (95% CI 1.2–1.9) for parkinsonism and 1.5 (95% CI 1.0–2.2) for PD.
DISCUSSION
Parkinsonism and PD were cross-sectionally associated with cognitive impairment and prospectively associated with incident dementia. These findings underscore the importance of routine screening for cognitive impairment in individuals with parkinsonism and PD, to facilitate early detection and intervention strategies that mitigate adverse outcomes.
Highlights
The present study is one of the first longitudinal investigations into the association of parkinsonism and Parkinson's disease (PD) with cognitive impairment and dementia incidence in Latin America.
Parkinsonism and PD showed strong cross-sectional associations with cognitive impairment, with consistent estimates across countries, independent of demographic factors.
Parkinsonism and PD were linked to a significantly higher incidence of dementia over a 4-year follow-up period.
Findings emphasize the need for routine cognitive screening in Parkinsonism and PD.
期刊介绍:
Alzheimer's & Dementia is a peer-reviewed journal that aims to bridge knowledge gaps in dementia research by covering the entire spectrum, from basic science to clinical trials to social and behavioral investigations. It provides a platform for rapid communication of new findings and ideas, optimal translation of research into practical applications, increasing knowledge across diverse disciplines for early detection, diagnosis, and intervention, and identifying promising new research directions. In July 2008, Alzheimer's & Dementia was accepted for indexing by MEDLINE, recognizing its scientific merit and contribution to Alzheimer's research.
