Supplementary Material for a Case Report on Punding in CANVAS

A single case report details the first documented instance of punding, a stereotypical behavior, in a patient with Cerebellar Ataxia with Neuropathy and Vestibular Areflexia Syndrome (CANVAS). The report describes a patient's ten-month history of paper-ripping behavior for over ten hours daily, with no dopaminergic therapy or substance abuse history.

Use Cases

• Analyzing the clinical presentation of punding based on the detailed case description of behavior and neurological examination.
• Studying the neurological basis of complex repetitive behaviors based on the reported absence of basal ganglia involvement.
• Reviewing rare neurological case reports for educational or comparative research based on the first documented case in CANVAS.

Strengths

• The case report provides a detailed, first-time clinical description of punding in CANVAS.
• The report includes specific clinical details, such as a ten-month history of behavior lasting over ten hours daily.

Limitations

• The dataset is a single PDF file of 288.6 KB, representing a single case report with limited scope.
• Row count and column-level documentation are absent; data structure must be inferred from the narrative text.
• Description metadata is limited; actual data quality requires manual inspection after download.
