Unformatted text preview: Affective Spectrum Disorder: 552 Am J Psychiatry 147:5, May 1990 Does Antidepressant Response Identify a Family of Disorders With a Common Pathophysiology? James I. Hudson, M.D., and Harrison G. Pope, Jr., M.D. Response to pharmacologic treatments may identify groups of disorders with a common pathophysiology. The authors applied a treatment-response model, based on four classes ofantidepressants (tricyclic types, mon- oamine oxidase inhibitors, serotonin uptake inhibitors, and atypicalagents), to the medicalliterature. The mod- el identified eight disorders that may share a patho- physiologic abnormality: major depression, bulimia, panic disorder, obsessive-compulsive disorder, atten- tion deficit disorder with hyperactivity, cataplexy, mi- graine, and irritable bowel syndrome. Phenomenologic and family studies support this grouping. If the model is validated, this family ofdisorders, which the authors term “affective spectrum disorder, “ would represent one of the most prevalent diseases in the population. (Am J Psychiatry 1990; 147:552-564) M any psychiatric and medical disorders respond to antidepressant medications. Because these disorders may respond fully to antidepressants from several unrelated chemical classes, it follows that they may share a pathophysiologic “step” in the etiologic chain of steps required for their expression. We de- scribe the development and application of a model de- signed to identify members of this proposed family of disorders, here termed “affective spectrum disorder.” The disorders identified include major depression, bu- limia, panic disorder, obsessive-compulsive disorder, attention deficit disorder with hyperactivity, cataplexy, Received April 21, 1989; revision receivedjuly 28, 1989; accepted Aug. 10, 1989.
