I do not believe OCD is a "psycho fad" as you put it. It is a very difficult and painfull condition. It creates nightmares in life for those who have serious symptoms.

However, if you are interested in mental health relating to the Artistic Temperment you could read "Touched With Fire" by Kay Redfield Jamison.

It offers interesting comparisons. It does focus more on Manic-Depressive Illness however.
