Psychotropic polypharmacy and use of all psychotropic subgroups were more frequent in the PD than in the non\u2010PD cohort throughout the follow\u2010up. In comparison, cohort BZDRs were the most frequently used psychotropics during the whole follow\u2010up. In the PD cohort, BZDRs were the most frequently used psychotropic group until three years after PD diagnosis, with the highest prevalence just before the index date (19.4%). After that, antidepressants were the most commonly used psychotropics. In the PD cohort, the psychotropic polypharmacy increased from 5% to 10% during the follow\u2010up. The differences were not explained by dementia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The results likely reflect the onset of non\u2010motor symptoms already before diagnosis and increasing symptomatology with disease progression.
