Cognitive assessment instruments in Parkinson's disease patients undergoing deep brain stimulation

INTRUMENTOS DE AVALIAÇÃO COGNITIVA EM INDIVÍDUOS COM DOENÇA DE PARKINSON SUBMETIDOS À ESTIMULAÇÃO CEREBRAL PROFUNDA

ABSTRACT

Deep Brain Stimulation (DBS) is a widely used surgical technique in individuals with Parkinson's disease (PD) that can lead to significant reductions in motor symptoms.

Objectives:

To determine, from publications, the most commonly used instruments for cognitive evaluation of individuals with PD undergoing DBS.

Methods:

A systematic review of the databases: PubMed, Medline, EBECS, Scielo and LILACS was conducted, using the descriptors "Deep Brain Stimulation", "Verbal Fluency", "Parkinson Disease", "Executive Function", "Cognition" and "Cognitive Assessment" in combination.

Results:

The Verbal Fluency test was found to be the most used instrument for this investigation in the studies, followed by the Boston Naming Test. References to the Stroop Test, Trail Making Test, and Rey's Auditory Verbal Learning Test were also found.

Conclusions:

The validation of instruments for this population is needed as is the use of batteries offering greater specificity and sensitivity for the detection of cognitive impairment.

Key words:
Parkinson's disease; cognition; deep brain stimulation

RESUMO

A Estimulação Cerebral Profunda (ECP) tem sido uma técnica cirúrgica bastante utilizada devido à redução significativa dos sintomas motores.

Objetivos:

Verificar, a partir das publicações, quais os instrumentos mais utilizados para avaliação cognitiva em pacientes com DP submetidos à ECP.

Métodos:

Foi realizado uma revisão sistemática nas bases de dados PubMed, Medline, EBECS, Scielo e LILACS utilizando os descritores "Deep Brain Stimulation", "Verbal Fluency", "Parkinson Disease", "Executive Function", "Cognition" e "Cognitive Assessment" de forma combinada.

Resultados:

O teste de Fluência Verbal o instrumento mais utilizado para esta investigação nos estudos encontrados, seguido pelo Teste de Nomeação de Boston. Foram também encontradas referências aos testes Teste de Stroop, Teste das Trilhas, Teste de Aprendizado Auditivo Verbal de Rey.

Conclusões:

A validação de instrumentos para esta população se faz necessária bem como a utilização de baterias com mais especificidade e sensibilidade para detecção das alterações cognitivas nesta população.
