Autres syndromes parkinsoniens

Numerous causes may induce parkinsonism, and in case of Parkinsonism, l-dopa resistance, associated neurological signs, early falls, early dysautonomia or early cognitive disorders are the main red flags which should lead to exclude Parkinson's disease. Drug-induced parkinsonism and in young people, Wilson disease, should always be searched. Lower limbs parkinsonism is often due to vascular lesions. Multiple systemic atrophy, supranuclear palsy, Lewy body disease and the rarer corticobasal degeneration, each have specific clinical signs. Genetic causes are rarer.
