The sociocultural context of psychiatric patients shapes symptoms experience and expression, as well as how patients deal with a disorder and how society appraises its symptoms. Specifically, the context may influence the social appraisal of a behavior as normal or pathological. Therefore, markedly pathological symptoms may not be accordingly recognized by peers when they are in consonance with the sociocultural context. Per “Dead” Ohlin was a Swedish musician who was a member of the Norwegian black metal band Mayhem from 1988 until his suicide in 1991, at age 22. Black metal is a musical movement characterized by death worshiping and anti-Christianism, and is also associated with church arsons and murders during the 1990s. Even among peculiar personalities such as black metal musicians, Ohlin was considered the personification of the movement ideals due to his eccentric and unparalleled beliefs and behaviors, claiming, for instance, that he was already dead. In this article, we propose that Ohlin's eccentric beliefs and behaviors were symptoms of an unrecognized psychiatric condition, Cotard's syndrome, and discuss the diagnostic dilemma presented by Ohlin's artistic persona and singular context. The compatibility between his symptoms and the sociocultural context of black metal may have obscured his mental disorder. If so, Ohlin's unique case may shed light upon one of the effects of context in a psychopathological process: concealing a psychiatric disorder and reinforcing symptoms that fit a particular environment.
