Two-Year Neuropsychological Monitoring After Unilateral and Bilateral Subthalamic DBS

A 2-year longitudinal study monitoring cognitive function, mood, and quality of life in 30 Parkinson's disease patients undergoing deep brain stimulation. The dataset, authored by Szczepan Iwański and last updated in May 2026, includes assessments at baseline, 6 months, and 24 months post-surgery.

Use Cases

• Analyze longitudinal trends in cognitive function based on repeated assessments over a 2-year period.
• Compare outcomes between unilateral and bilateral DBS patient subgroups mentioned in the description.
• Model the relationship between motor improvement and stability of mood or quality of life metrics.
• Assess individual patient cognitive decline against normative data, as referenced in the results.

Strengths

• Longitudinal design with three assessment time points over 2 years.
• Cohort of 30 patients with detailed neuropsychological monitoring.
• Focus on three critical cognitive domains: attention/processing speed, learning/memory, and executive functions.

Limitations

• Dataset is small at 32.1 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
