"Why would Parkinson’s disease lead to sudden changes in creativity, motivation, or style with visual art?: A review of case evidence and new neurobiological, contextual, and genetic hypotheses" by Lauring, Ishizu, Kutlikova, Dörflinger, Haugbøl, Leder, Kupers, and Pelowski (2019)

This academic article examines the phenomenon of Parkinson’s disease (PD) patients suddenly developing or increasing their artistic output. The authors explore the neurobiological mechanisms, particularly the role of dopamine systems and pharmacotherapy, in driving this unexpected creativity. They propose that damage to specific brain regions, combined with the effects of medication, may lead to changes in reward processing, inhibition, and cognitive flexibility, contributing to a surge in artistic motivation and production. The article also discusses the importance of individual factors, such as personality traits and genetic predispositions, in modulating this phenomenon.
