RidgelSummaryObjectivesTo investigate cerebral perfusion as a potential mechanism of exercise-related cognitive improvements and to further associate cognition and cerebral perfusion in Parkinson's disease.Equipment and methodsCerebral perfusion was measured continuously at rest and during a cognitive task using near-infrared spectroscopy before and after a multifaceted exercise program in thirteen individuals with Parkinson's disease.ResultsCognitive function was not significantly impaired in our group of Parkinson's disease participants at baseline. Cerebral perfusion (69.91% ± 2.43) was significantly greater during cognitive testing than while resting (68.12% ± 2.42) (P ≤ 0.001). Our results are inconclusive with respect to the effect of exercise on cognitive dysfunction in PD.RésuméObjectifsInvestiguer la perfusion cérébrale comme un mécanisme potentiel de l’amélioration cognitive liée à l’exercice et associer davantage la cognition et la perfusion cérébrale dans la maladie de Parkinson.Matériel et méthodesLa perfusion cérébrale a été mesurée en permanence au repos et au cours d’une tâche cognitive en utilisant la spectroscopie proche infrarouge avant et après un programme d’exercices à multiples facettes chez treize personnes atteintes de la maladie de Parkinson.Résult...
