La maladie de Parkinson idiopathique : une maladie métabolique ?
Résumé
Parkinson's disease is a neurodegenerative disorder clinically characterized by motor impairments (tremor, bradykinesia, rigidity and postural instability) associated or not with non-motor complications (cognitive disorders, dysautonomia) Most of patients loose weight during evolution of their disease Dysregulations of hypothalamus, which is considered as the regulatory center of satiety and energy metabolism, could play a major role in this phenomenon Deep brain stimulation of the subthalamic nucleus (NST) is an effective method to treat patients with advanced Parkinson's disease providing marked improvement of motor impairments. This chirurgical procedure also induces a rapid and strong body weight gain and sometimes obesity. This post-operative weight gain, which exceeds largely weight lost recorded in non-operated patient, could be responsible of metabolic disorders (such as diabetes) and cardiovascular diseases. This review describes body weight variations generated by Parkinson' disease and deep brain stimulation of the NST, and focuses on metabolic disorders capable to explain them: Finally, this review emphasizes on the importance of an adequate nutritional follow up care for parkinsonian patient (C) 2010 Elsevier Masson SAS All rights reserved
