Current evidence indicates that over two-thirds of mooddisorders pursue a recurrent or chronic course. Yet much ofthe progress recorded in the field of mood disorders andtheir treatment has been in research into the acute phase ofthe illness. Hence there is a need for a volume thatspecifically addresses the special clinical problemsencountered inthe recurrent forms of these disorders.The various chapters of this book embrace a wide range oftopics, including etiology, course, and long-term treatment,integrative reviews, results of recent investigations, andclinical reports. In this respect, the contributions reflectcurrentconcepts, research, and clinical practice. We haveendeavored to build a bridge between neurobiology andpsychology and have covered both the psychotherapeutic andthe psychopharmacologic aspects of mood disorders.
