Dyskinésies dopa-induites dans l'atrophie multi-systématisée de type parkinsonienne

Dyskinesias are well-known side effects of the dopaminergic treatment in Parkinson's disease. In multiple system atrophy (MSA), these events are less well studied because of the low incidence of this disease and their relatively low frequency amongst patients suffering from this condition. Optimizing dopaminergic treatment in patients with MSA is difficult for two main reasons: the clinical benefit is sometimes hard to evaluate and the signs of the dopa-induced dyskinesia are not well-known. We report the case of a 65-year-old male patient with a parkinsonian variant of MSA who present repeated dystonic accesses involving the neck and face and partially responsive to continued dopaminergic stimulation with an apomorphine pump.
