The author stresses early detection of the premonitory signs of a manic breakdown with a view towards an efficient therapeutic intervention. Some of the most typical signs are described with their corresponding dynamic implication. The manic-depressive's lack of impulse control often forces a member of the patient's circle to take control. After a review of the main personality traits belonging to the manic-depressive patient, the author gives a description of the patient's spouse in whom appear similar and complementary elements of the patient's personality. Finally, some steps are suggested to rationalize treatment. Emphasis is on educational methods combined with lithium therapy within the framework of a therapeutic relationship where the interactive dynamic forces are acknowledged.
