Abstract
Background and purpose Creative drive and enhanced artistic like production may emerge in patients with Parkinson’s disease (PD) during dopaminergic therapy. Recently we suggested that newly acquired artistic-like production in PD patients might represent the emerging of innate skills in a subset of predisposed patients and not associated with impulsivity or impulse control disorders. Moreover changes in painting style after treatment onset has been described in case report. Nonetheless no data are available in de novo PD patients (PD-dn) and in professional artists with PD (PD-art). We investigated creative thinking in de novo PD patients with any dopaminergic treatment and in PD-art by means of the abbreviated Torrance test for adults (ATTA). Methods We investigated creative thinking in a cohort of cognitively preserved PD-dn patients and PD-art patients. We also investigated healthy controls (HC), with (HC-art) and without (HC-na) professional artistic job, by means of the ATTA. Results Mean ATTA score of PD-art was found to be similar to HC-art (73.6 ± 22.4 vs 97.0 ± 29.1, respectively) and of PD-dn vs PD-na (55.9 ± 29.6 vs 55.6 ± 24.6). PD-art and HC-art had significant higher ATTA score than PD-na and HC-na, respectively ( p Conclusions Our study suggests that creative thinking is not correlated with dopaminergic therapy in PD patients with and without professional artist job. These results are in accordance with the hypothesis that dopaminergic system is involved in creative drive and but not in idea generation.
