 In a once-common practice, mental or “functional” disorders were diagnosed just when no somatic traits were evident. Such language is now explicitly disavowed, eclipsed by a growing confidence that all disorders involve bodily states (Sykes 2010; APA 2013: 309). Still, the “mental” in mental disorder is variously construed. In this section we'll first consider different views on "where" in disorder that mentality lies and, then, different views on what it consists in.
