ABSTRACT High education has been associated with faster cognitive decline after diagnosis of Alzheimer's disease (AD), but it is unclear whether these findings extend to other dementia subtypes.
OBJECTIVE:
We investigated whether educational attainment influences the cognitive trajectories of older adults with different dementia subtypes.METHODS:
All participants were selected from NEDICES, a prospective population-based cohort study of Spanish older adults. A total sample of 53 individuals with dementia completed the MMSE-37 at Times 1 and 2 (mean follow-up=2.8±0.5 years) to assess cognitive decline.RESULTS:
At follow-up, MMSE-37 scores had decreased by 3.34±4.98 points in low-educated individuals with dementia versus 7.90±4.88 points in high-educated subjects (effect size (r)=0.32, p=0.02).CONCLUSION:
Educational level influenced the cognitive trajectories of patients with dementia assessed by the MMSE-37.
RESUMO A educação mais alta tem sido associada com um declínio cognitive mais rápido após o diagnóstico de doença de Alzheimer (DA), mas não está claro se estes achados podem ser extendidos a outros subtipos de demência.
