Despite the motor and executive deficits that occur in Parkinson's disease, some patients on levo-dopa or dopamine agonists report either an enhancement of their existing artistic and creative abilities or an emergence of such abilities in the previously art-naïve. Genres of artistic expression include drawing, painting, sculpting, music, writing and so on. Although mechanisms such as dopamine dysregulation are proposed to explain this phenomenon, treatment with levo-dopa is consistently noted. From a clinical perspective, this is a helpful outlet for patients' self-expression, leading to better mood state, enhanced self-esteem and better quality of life. Such artistic expression is therapeutic; it's a form of art therapy.
