Parkinson's Disease Clinical Course in Japan: 2.5-Year Observational Study

A 2.5-year observational study of 348 patients with Parkinson's disease at Juntendo University Hospital in Japan. The data includes baseline characteristics and longitudinal clinical status, such as Unified Parkinson's Disease Rating Scale (UPDRS) motor scores, to explore factors associated with disease progression. The dataset was authored by Kei-ichi Ishikawa and is available under a CC-BY-4.0 license.

Use Cases

• Modeling disease progression based on longitudinal Unified Parkinson's Disease Rating Scale (UPDRS) motor scores.
• Identifying prognostic factors for clinical worsening based on baseline motor severity and orthostatic hypotension.
• Analyzing treatment patterns and outcomes in a Japanese patient cohort receiving standard therapy, including L-dopa usage.

Strengths

• Includes longitudinal data tracking patients for up to 2.5 years.
• Provides specific clinical metrics, including mean UPDRS III scores, Hoehn and Yahr stage, and L-dopa dosage.
• Dataset is small (377.9 KB), facilitating quick download and initial exploration.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is sourced from a single hospital in Japan, which may limit generalizability.
