Abstract (eng)
Parkinson’s Disease (PD), a neurodegenerative disorder, impacts one’s motoric and non-motoric functions and presumably deteriorates the work or professional life of an artist. Interestingly, some of previous studies on creativity/art in PD patients revealed that PD patients increased their creativity and those who were artists maintained their artistry. Despite these compelling reports, the studies had caveats (i.e., insufficient documentation and small sample size, resulting in questionable findings). To verify the creativity/art changes reported by PD patients, an epidemiological survey study was conducted. This thesis is a part of a larger study in Austria, in which the survey was adapted from a running survey in the Netherlands. The study was introduced to several Parkinson’s organizations, associations, and medical practitioners specializing in PD. The current results showed that PD patients (N = 19) in Austria differentiated their feeling of being creative and creative expression over three timepoints, namely pre-diagnosis (the period after the onset of PD symptoms but before the onset of PD diagnosis), post-diagnosis (after the onset of diagnosis), and current (three months before the study was conducted) timepoints. Over these timepoints, the percentage of total participants that reported increased, decreased, or showing no change in the feeling of being creative was 39%, 31%, and 30%, respectively. Additionally, the percentage of participants that reported increased, decreased, or no change in creative expression (i.e., actual producing creative products and/or actual creative activities) was 37%, 35%, and 28%, respectively. This thesis also explored: (1) The relationship between the reported changes with creative/art education status, (2) The causes of creativity changes perceived by PD patients, and (3) the possible relationship between PD medication, particularly DA agonists and levodopa, and creativity changes.
