| Résumé : | Parkinson's disease in a neurodegenerative disorder that affects as many as 1-2 % of persons aged 60 years and older. Parkinson's disease occurs infrequently under 40 years of age, with major genetic implication. Alpha-synuclein plays significant pathogenic role in Parkinson's disease. Therapeutic advances based on a synucleinrelated mechanism are now developed : Immunotherapy against alpha-synuclein for example. The diagnosis of Parkinson's disease remains mostly clinical. DatScan® may be helpful to distinguish parkinsonian syndrome and essential tremor. Current therapy is mainly based on a dopamine replacement strategy using the precursor levodopa (L-Dopa) and dopamine receptor agonists. Parkinson's is also associated with non-motor symptoms like sleep disorders, autonomic symptoms, neuropsychiatric symptoms. Advanced disease is associated with emergence of feature such as freezing, falling and neuropsychological dysfunction. Nonpharmacologic treatments like exercise are fundamental elements of patients' management . Motor complications and dyskinesia are common in advanced Parkinson's disease. Continuous administration of L-Dopa/carbidopa infusion in the jejunum provides more continuous dopaminergic drug delivery and stimulation and reduce motor complications. Fur ther other approach are developped like surgical procedures: Ex : High frequency stimulation of subthalamic nucleus, the more rational target for stimulation in Parkinson's disease. |
