Abstract:
Emerging research findings in mood disorders continue to provide support for multifactorial etiology. The present review considers the role of familial and developmental factors, gender, life circumstances, and biological precipitants in pathogenesis and discusses how they might, hypothetically, interact with other psychological and biological traits in giving rise to clinical heterogeneity. Special consideration is given to the pathoplastic influence of characterologic and temperamental traits, in view of their current clinical visibility.
