Leo Schnug: alcoholic dementia as an unexpected source of inspiration for an artist.

Artistic creativity can be defined as the ability to challenge established academic representations or tastes, and to produce both innovative and esthetic works. Here, we investigate the influence of alcoholic dementia on creativity by describing the case of the famous painter Leo Schnug. It is clear that Schnug's motor and psychic disorders had a dramatic influence on his late artistic output. His hallucinations, panic attacks and delusions had an influence on both the themes and the personal, expressionistic and easily recognizable style of his work. It is unlikely that he would have attained these had he been in good health.
