Creativity can arise in some Parkinson's disease (PD) patients as a side effect of dopaminergic therapy. Schizotypal traits-subclinical traits resembling schizophrenia symptoms-can mediate some effects of dopaminergic drugs on cognition and neural activity. The goal of our study was to relate general intelligence, creative achievement and schizotypal traits to changes in performance on the Just Suppose test (from the Torrance battery), a task designed to measure verbal divergent thinking. Patients with PD and controls were examined at baseline, and at a follow-up session 12 weeks after pharmacotherapy had begun. Patients received dopamine agonist monotherapy (pramipexole and ropinirole). We observed significantly elevated positive schizotypy and impulsivity in PD at follow-up, while divergent thinking scores increased at trend level in the patient group. Linear regression analyses revealed that changes in various aspects of divergent thinking in PD were related to positive and disorganized schizotypy and lifetime creative achievement. The results highlight the relevance of schizotypal traits and lifetime creative achievement to the development of creativity in PD during dopaminergic therapy. The research draws attention to individual differences associated with a side effect of dopaminergic therapy in PD and also contributes to the understanding of the biological aspects of creativity.
