Neurorhetoric, the study of how language is used in the creation, distribution, and reception of science about the brain, has recently become an important topic in medical rhetoric and composition studies, as well as in popular science publications targeted at non-scientists.[29] Information and texts relevant to the rhetoric of mental health include psychotropic pharmaceutical regulations, their production, prescription, advertising, and consumption, and scientific and popular discussions about major depressive disorder, bipolar disorder, obsessive-compulsive disorder, schizophrenia, autism, and other mental disorders.[30][31] The Diagnostic and Statistical Manual of Mental Disorders (DSM, now in its 5th edition) is a central text for the study of the mental health profession.
