Drug-induced parkinsonism (DIP) is the second most common cause of parkinsonism in the elderly after idiopathic Parkinson disease. We report the case of an elderly man who had long-standing paranoid schizophrenia and DIP; both sets of symptoms improved with a course of 8 bilateral electroconvulsive therapies (ECTs). Improvement in DIP was maintained for 6 months, despite stopping ECTs. The role of ECT in DIP needs more systematic evaluation. Electroconvulsive therapy may be useful for elderly individuals with both psychotic symptoms and parkinsonism, which does not respond to conventional treatment regimes.
