[Cerebellar side effects in treatment with antidepressive agents].

Nine patients are reported with marked cerebellar side-effects under antidepressant treatment, mostly in combination with other psychopharmacological agents. The main symptoms were dysmetria, ataxia, intentional tremor, dysarthria and rarely myocloni. In nearly all cases symptomatology disappeared by slight dosis reduction of the antidepressant. Pathophysiology could be best explained by influence on nonadrenergic afferences of cerebellar cortex.
