Objective: Weight loss is common in patients with Parkinson's disease (PD). It has been reported that low Body Mass Index (BMI) is associated with disease progression in these patients, but only a few data are available on the relationship between BMI and cognitive dysfunctions in PD patients. In the present study we systematically assessed the possible relationship between BMI index and specific cognitive defects. Method: We enrolled a prospective sample of 37 PD individuals and 30 healthy controls (HC) of similar age, sex, and education. The BMI was calculated in each participant, who underwent a neuropsychological assessment exploring the general cognitive skills, frontal/executive, visuo-spatial, visuo-constructional and memory abilities. Results: We showed that PD group had significant lower BMI value compared to HC group. In PD patients, the BMI was negatively correlated to disease duration and number of errors at the Stroop-Color Word Test, and positively to score on Frontal Assessment Battery (FAB). Moreover, a regression analysis revealed that, the BMI in PD patients was associated with disease duration and score on FAB. Conclusions: Our findings contribute to reveal that the relationship between height and weight is strongly related to frontal cognitive dysfunctions in PD patients.

Abstract

Objective: Weight loss is common in patients with Parkinson's disease (PD). It has been reported that low Body Mass Index (BMI) is associated with disease progression in these patients, but only a few data are available on the relationship between BMI and cognitive dysfunctions in PD patients. In the present study we systematically assessed the possible relationship between BMI index and specific cognitive defects. Method: We enrolled a prospective sample of 37 PD individuals and 30 healthy controls (HC) of similar age, sex, and education. The BMI was calculated in each participant, who underwent a neuropsychological assessment exploring the general cognitive skills, frontal/executive, visuo-spatial, visuo-constructional and memory abilities. Results: We showed that PD group had significant lower BMI value compared to HC group. In PD patients, the BMI was negatively correlated to disease duration and number of errors at the Stroop-Color Word Test, and positively to score on Frontal Assessment Battery (FAB). Moreover, a regression analysis revealed that, the BMI in PD patients was associated with disease duration and score on FAB. Conclusions: Our findings contribute to reveal that the relationship between height and weight is strongly related to frontal cognitive dysfunctions in PD patients.
