A program is described for the rapid detection and control of hypomanic episodes. This program has four salient features.1. A systematic search for a pathognomonic tell-tale sign in each patient which heralds the onset of an attack.2. The education of the patient and his family to the importance of detecting and reporting such signs or even suspicions of impending signs without delay.3. The use of ancillary personnel to maintain regular monthly contacts with the patient and the family during symptom-free periods and to provide additional clinical observations. This program provides a financial saving for the patient and a reduction of the time demand on the psychiatrist while maintaining therapeutic efficiency.4. The carefully controlled, intensive and early use of LiCO3 as the primary approach to alleviate hypomanic states. Lithium therapy approaches 100 percent effectiveness if used at the first sign of a hypomanic attack.This program has proven both successful and practical for the management of a condition previously considered very difficult to treat.
