Emotional behavior after a Wada test in a patient with secondary mania
Abstract
Soon after treatment of a right basotemporal vascular malformation using an embolization procedure, a 25-year-old patient developed an acute episode of mania. Two months later the patient was still manic, and a second embolization was scheduled. Before it was conducted, a Wada test was carried out to determine speech dominance. No changes in manic symptoms were observed after amytal injections into the left middle cerebral, right frontopolar, or right middle cerebral arteries. This finding suggests that secondary mania may not be the result of "release" of the left hemisphere following a right hemisphere lesion but instead may be related to specific disturbances within the right hemisphere.
