Traitement de la maladie de Parkinson en 2009.

The cause of Parkinson's disease remains unknown and no cure or prevention exists so far. Levodopa remains by far the most potent symptomatic therapy, but induces side-effects such as motor fluctuations and abnormal movements, which can somewhat be counterbalanced by optimizing levodopa plasma levels or acting at receptors level with long half-life dopamine agonists. In severe cases, functional surgery with deep brain stimulation can be offered. Some non-dopaminergic symptoms like dementia, freezing, postural instability or dysautonomia do not respond to dopaminergic drugs and need special care.
