Background: The Segawa syndrome is an autosomal dominant form of guanosine triphosphate cyclohydrolase deficiency, resulting in decreased dopamine and serotonin levels, typically presenting as a dopa-responsive dystonia.
Method: Case presentation of a 56-year-old man with dopa-responsive dystonia, treated with electroconvulsive therapy for a psychotic depression.
Results: Scores on the Inventory of Depressive Symptomatology dropped from 35 before treatment to 3 after the eighth treatment session. Etomidate and succinylcholine were used as anesthetics. Apart from 2 sessions with postictal agitation, the course of electroconvulsive therapy was finished uneventfully. Electroconvulsive therapy and anesthesia had no untoward effects on motor function.
Conclusions: Electroconvulsive therapy can be administered safely and effectively in a patient with dopa-responsive dystonia (Segawa syndrome).
