A third of Parkinson's disease (PD) patients suffer from an anxiety disorder at any time point (1)

  • can precede or follow PD motor symptoms
  • anxiety is associated with demographic, disease-related motor and non-motor features

Retrospective study (UK data) found risk of developing Parkinson’s disease (PD) was at least doubled in people with anxiety vs those without (2):

  • in those with anxiety, the presence of depression, hypotension, tremor, rigidity, balance impairment, constipation, sleep disturbance, fatigue, and cognitive impairment were associated with an increased risk of developing PD
    • clinical features of those who developed PD can help identify patients presenting with anxiety who are in the prodromal phase of PD
