title: [Abnormal movements induced by psychotropic drugs].
abstract: The abnormal movements produced by the psychotropic drugs are related to various physiopathological mechanisms: -- dopaminergic receptors blockage provokes neuroleptic parkinsoniam tremor; -- neuroleptic-induced tardive dyskinesia is similar to 1. Dopa abnormal movements; tardive dyskinesia is due to denervation induced hypersensitivity of the dopamine receptor; the 1. Dopa dyskinesia is probably related to altered responsiveness of these receptors due to an increase in dopaminergic receptor sensitivity; -- antidepressant drugs, particularly lithium, provoke tremor, alleviated by beta blockage; it is probably caused by an abnormal sensitivity of the beta noradrenergic receptors.
