To assess the incidence of anxiety disorders following a diagnosis of Parkinson's disease using a nationwide cohort.
Key Findings:
The incidence rate of anxiety disorder was 56.62 per 1,000 person-years in Parkinson's patients compared to 28.10 in controls.
The incidence rate ratio for anxiety disorder in Parkinson's patients was 2.01.
The increased risk of anxiety disorder was most pronounced in the first three years post-diagnosis and during long-term follow-up.
Interpretation:
Patients with Parkinson's disease have a significantly higher risk of developing anxiety disorders compared to the general population, indicating a need for ongoing mental health assessments.
Limitations:
The study may not account for all confounding factors influencing anxiety disorders.
Data is limited to a specific population in Korea, which may affect generalizability.
Conclusion:
Anxiety disorder is a critical non-motor symptom of Parkinson's disease, necessitating regular mental health monitoring in affected individuals.
