Table 3_Two-year longitudinal neuropsychological monitoring after unilateral and staged bi

30 patients with Parkinson's disease were monitored for cognitive function, mood, and quality of life over a 2-year period following subthalamic nucleus deep brain stimulation (DBS). The dataset, authored by Szczepan Iwański and shared under CC-BY-4.0, contains results from assessments conducted before surgery, at 6 months, and at 24 months post-surgery. Analysis of the cohort showed no overall decline in cognitive function or mood, alongside significant motor improvement.

Use Cases

• Analyze longitudinal trends in cognitive function based on assessments of attention, processing speed, learning, and memory.
• Compare outcomes between unilateral and staged bilateral DBS patient subgroups based on the study's comparative analysis.
• Model the relationship between motor improvement and non-motor symptoms like mood and quality of life over time.
• Benchmark patient cognitive scores against normative data to identify individual decline patterns as described in the results.

Strengths

• Longitudinal design with three assessment time points over 2 years.
• Focus on three critical cognitive domains: attention/processing speed, learning/episodic memory, and executive functions.
• Includes data from 30 patients, allowing for subgroup analysis of unilateral versus bilateral DBS.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 20.6 KB, indicating limited scope.
