Risperidone Monotherapy for Mania and Depression
Mr. A, a 27-year-old man of Chinese descent, was physically healthy and did not abuse substances. About 1 year ago, he was hospitalized for his first episode of DSM-IV psychotic mania. Elevated moods, lessened need for sleep, hyperactivity, pressured speech, flight of ideas, grandiosity, and visual, mood-congruent hallucinations significantly impaired various areas of functioning. Physical examinations, laboratory tests, drug screening, chest X-rays, an ECG, and an EEG all produced negative results. In addition, his elder brother was also a victim of bipolar disorder. Mr. A and his father gave written informed consent for him to receive risperidone monotherapy; his dose was titrated to 3 mg b.i.d. over 3 days. Both psychotic and mood symptoms vanished within 3 weeks; he was then transferred to our outpatient department with the same drug regimen.Two weeks later, Mr. A abruptly discontinued his medication because of a lack of full insight; after 6 days, a less severe manic state (without psychotic features) returned. Five days later, risperidone alone (3 mg b.i.d.) was reinstituted, abating his mood turmoil over 1 week. Unfortunately, 1 month later, he again discontinued his medication; a DSM-IV major depressive episode with melancholic features ensued 1 week later. Distinct depressed moods, significant anorexia, early morning awakening, loss of energy, marked psychomotor retardation, loss of pleasure in all activities, excessive guilt, and feelings of hopelessness caused drastic distress. After another 2 weeks, the same monotherapy alleviated the depressive state within 1 week. Three weeks later, Mr. A halted the medicine for a third time. Thereafter, he was free of psychotic and mood symptoms for 9 months, until another major depressive episode (with similar symptoms) developed. Two weeks later, the earlier treatment strategy curtailed this episode over 1 week. No adverse drug reaction ever emerged; no other medication, even as an adjunct, was coadministered throughout.
