Abstract
in English, Portuguese

Cognitive functions, such as impulsiveness and executive functions, are often impaired in Parkinson's disease.

Objective: to analyze the relationship between impulsiveness and executive functions (EF) in people with Parkinson's disease (PD).

Methods: a correlation study involving a sample of 50 patients with an established diagnosis of PD aged 40 years or older was conducted using the following instruments: Demographic Questionnaire, Montreal Cognitive Assessment Basic (MOCA-B), Barratt's Impulsiveness Scale (BIS-11) and Frontal Assessment Battery (FAB).

Results: Pearson's correlation analysis indicated low associations (p<0.05) between the MOCA-B and BIS-11, with a value of -0.11, and between the FAB and BIS-11, with a value of -0.16. A significant correlation between the MOCA-B and FAB was found, with a value of 0.73.

Conclusion: this study revealed an association between EF and other cognitive functions, but no association between impulsivity and EF in Parkinson's disease.

As funções cognitivas, tais como impulsividade e funções executivas, muitas vezes estão alteradas na doença de Parkinson. Objetivo: analisar a relação entre a impulsividade e as funções executivas (FE) em pessoas com a doença de Parkinson (DP). Métodos: estudo de correlação, com uma amostra de 50 pessoas a partir de 40 anos de idade, com diagnóstico estabelecido da doença de Parkinson utilizando-se os seguintes instrumentos: Questionário Demográfico, Montreal Cognitive Assessment Basic (MOCA-B), Escala de Barrat para Impulsividade (BIS-11) e Frontal Assessment Batery (FAB). Resultados: a análise de Correlação de Pearson indicou baixas associações (p<0,05) entre o Moca-B e BIS-11 com -0,11 e o FAB com o BIS-11 tiveram um valor de -0,16. O valor que teve significativa correlação apareceu no Moca-B com o FAB 0,73. Conclusão: este estudo evidenciou uma associação entre as FE e outras funções cognitivas, mas não evidenciou associação entre impulsividade e funções executivas na doença de Parkinson.

Keywords: Parkinson disease; cognition; executive function; impulsiveness.
