Behavioral neuropsychology: past, present, and future direction with organically based affect/mood disorders.

Affective/mood disturbances have been widely described in association with central nervous system dysfunction. There have been multiple divergent viewpoints regarding the origin of these disorders, however. This is not surprising, as theories evolve in relation to our degree of technological advancement. This review describes the evolution of some of these views, and discusses the advantages of behavioral neuropsychology as an effective approach to assessment/treatment in this context. Although there have been few articles published describing the use of behaviorally based approaches to treat these disorders, it is thought that this approach shows promise, particularly when combined with information based on neuropsychological assessment data. Future directions for the continued evolution of this field are outlined.
