WORKING MEMORY IN ALZHEIMER DISEASE: A 5-YEAR SYSTEMATIC REVIEW OF EMPIRICAL EVIDENCES FROM BADDELEY’S WORKING MEMORY MODEL

Resumo

The Alzheimer’s disease is the most common of theneurogenerative conditions associated with dementia. Itis known as a pathological frame that comes with severalimpairments in cognitive and psychological processes.This study aimed to understand the relationship betweenAlzheimer’s disease and Working Memory impairments.We adopted Baddeley’s Working Memory Model tosystematically review if impairments in the subcomponentsof this theoretical model – phonological loop, visualsketchpad, episodic buffer and central executive – followdistinct or similar paths. The systematic review consultedMedline, Psycinfo and Scielo databases. From 329 articles,only 11 were accepted by the established criteria. Resultssuggested that episodic buffer and central executive,respectively, decline with AD severity. Phonological loopand visual sketchpad are the last of the Baddeley’s WorkingMemory Model subcomponents impaired.
