A review article by Janka Zoltan (2004) looks at the pattern of psychological disorders in a few celebrated artists, and it finds that there is a large prevalence of bipolar disorders in these artists. Bipolar mood disorder is largely defined by having phases of mania and depression. The manic phase is characterized by inflated self-esteem, less need for sleep, being talkative, irritable, having racing thoughts, greater activity (both positive and negative), and distractibility. The article suggests that the hypomania of bipolar disease could contribute to prolificness and creativity of great artists. Though it is not a novel concept, it is nevertheless an intriguing, perhaps poetic, idea that painful neurological disorder can very well have beautiful products.
