Many authors have argued that mental illness and creativity are linked. Perhaps most notably, psychologist Kay Redfield Jamison discussed the associations between mood disorder and creativity in her book Touched with Fire.
Although Jamison largely deals with literary figures, other researchers have noted high levels of mental disorder in jazz musicians, with one researcher even suggesting that Buddy Bolden, the founder of modern jazz, may have developed jazz improvisation in response to his cognitive impairments.
The kuro5hin article isn’t the most clearly structured piece you’ll ever read, but is brimming with ideas, and asks important questions about whether the suppresion of mental illness necessarily involves the suppresion of creative thought.
