Abstract
ABSTRACTCognitive 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.
Highlights
Cognitive functions, such as impulsiveness and executive functions, are often impaired in Parkinson’s disease
The main purpose of this article was to analyze the extent of the relationship between impulsiveness and executive functions (EF) in people with Parkinson’s disease (PD)
Other studies report similar results, where main changes in EF found on neuropsychological tests were observed on the Trail Making A and B, which evaluate cognitive flexibility, as well as on the Go-No-Go task.[20]
Summary
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). 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). According to Diamond (2014, pg. 136): “executive functions (EF)[6] are essential skills for mental and physical health, school and life success, cognitive, social and psychological development, quality of life, and public safety”
