Overcoming barriers in cognitive assessment of Alzheimer's disease

Superando barreiras na avaliação cognitiva da doença de Alzheimer

ABSTRACT

Diagnosis of Alzheimer's disease (AD) requires a reliable neuropsychological assessment, but major barriers are still encountered when such tests are used across cultures and during the lifespan. This is particularly problematic in developing countries where most of the available assessment tools have been adapted from developed countries. This represents a major limitation as these tests, although properly translated, may not embody the wealth of challenges that a particular culture poses on cognition. This paper centers on two shortcomings of available cognitive tests for AD, namely, their sensitivity to the educational background and to the age of the individual assessed.

Key words:
Alzheimer's disease; neuropsychological evaluation; cognitive assessment; diagnosis

RESUMO

O diagnóstico da doença de Alzheimer (DA) necessita de uma avaliação neuropsicológica de confiança, barreiras importantes ainda são encontradas quando esses testes são usados em através de culturas e durante a vida. Isto é particularmente problemático em países em desenvolvimento, onde a maioria das ferramentas de avaliação disponíveis foram adaptadas a partir de países desenvolvidos. Isto representa uma grande limitação, pois mesmo devidamente traduzidas, podem não pode capturar a riqueza de desafios que uma determinada cultura representa na cognição. Neste artigo vou me concentrar em duas falhas de testes cognitivos disponíveis para AD, sensibilidade ao nível educacional e idade do indivíduo avaliado.

Palavras-chave:
doença de Alzheimer; avaliação neuropsicológica; avaliação cognitiva; diagnóstico

    Associative memory and STM binding refer to two different integrative memory functions. The former entails the formation of complex experiences wherein each constituent element retains its own identity and can be flexibly and individually accessed and retrieved. The latter entails integrative functions responsible for the formation of objects' identity. Such representations are rigid and once the constituent parts are bound, they cannot be accessed individually as they become part of a new object. It is the whole object that can be retrieved.
