If this is true, then medication treatment and psychotherapy may be acting through a similar final common pathway – the brain. This view is supported by recent work in obsessive-compulsive disorder, where behavior therapywas shown to produce similar changes in positron emission
tomography neuroiniaging as did medication treatment, leading Baer81 to suggest that behavior therapy may be a form of “endogenous serotonin Inhibitors,research,lifescience,medical therapy.” More work will be needed in this fruitful field of translating psychotherapeutic treatment into alterations in brain structure and function. Once the brain is understood to be a final common pathway for both medication and psychotherapeutic treatments, then the importance of balancing biological and psychosocial approaches becomes more understandable. The brain mediates both treatment approaches. It may be, then, that
a mood disorder may have a largely biological origin, and yet be responsive to psychotherapy. Conversely, a mood disorder may be largely Inhibitors,research,lifescience,medical psychosocial in origin, and yet Ceritinib molecular weight respond to medication treatment. It is an elementary error of logic to reason from conclusion to premises; one must always work the other way around. While the etiology of a certain condition may be psychological, its pathogenesis may be biological and hence amenable to biological interventions (and, Inhibitors,research,lifescience,medical at least theoretically, vice versa). Hence, while the efficacy of pharmacological or psychotherapeutic treatments maygive us clues about where we need to look in the search for the etiologies of mood disorders, in themselves the fact that Inhibitors,research,lifescience,medical these treatments work does not establish
any specific etiology. Advances in neurobiology, in particular, should complement, rather than curtail, psychosocial research and psychotherapeutic practice. This perspective is supported by some Inhibitors,research,lifescience,medical recent psychosocial research in bipolar disorder. Since many outcome studies have found marked impairment in social and occupational functioning in bipolar disorder despite some symptomatic improvement pharmacologically, one might conclude that psychotherapeutic interventions are able to improve social and occupational functioning. Recent data support this Dacomitinib SB203580 PKB hypothesis, which experienced clinicians already know: combined psychosocial/pharrnacological strategies are more effective than medication alone, especially in improving function, reducing relapse, and preventing hospitalization. 82,83 Conclusions The state of the art in the diagnosis and treatment of bipolar disorder is both heartening and challenging. We have come a long way and appear to be headed in the right direction. However, we face a number of challenges, which, with effort and foresight, we should be able to meet. First, we need to avoid an historical tendency in psychiatry towards reductionism, which led to a swing away from biological work for much of this century.
