Anxiety Disorder Incidence Following Parkinson's Disease in a Korean Cohort, 2012-2023

Youngoh Bae's population-based cohort study, published on figshare in 2026, analyzes the risk of newly diagnosed anxiety disorders in patients with Parkinson's disease. The dataset includes 3,742 patients with Parkinson's disease and 18,710 matched controls from Korean National Health Insurance Service data between 2012 and 2023. It reports an incidence rate of anxiety disorder of 56.62 per 1,000 person-years in the Parkinson's cohort, compared to 28.10 in controls.

Use Cases

• Estimating time-dependent risk of anxiety disorders based on the described incidence rate ratios and hazard ratios.
• Analyzing psychiatric symptom patterns in Parkinson's disease based on the described non-motor manifestations.
• Training models for longitudinal mental health monitoring based on the described follow-up periods.
• Studying population-level disease associations using the described matched cohort design and propensity score matching.

Strengths

• Includes a matched control group at a 1:5 ratio (18,710 controls for 3,742 patients).
• Uses a nationwide population-based sample from a national health insurance service.
• Covers a longitudinal time range from 2012 to 2023.
• Provides specific incidence rates (56.62 vs. 28.10 per 1,000 person-years) and an incidence rate ratio (2.01).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the primary data tables is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Korean source population.
