Neurocognitive Safety of Endoscopic Colloid Cyst Resection: Paired Pre- and Post-Operative Cognitive Function from an...

Area of Science:

• Neurosurgery
• Neuropsychology
• Cognitive Science

Background:

• Colloid cysts in the third ventricle are rare pathologies.
• Their proximity to critical brain structures raises concerns about potential cognitive decline.
• Comprehensive pre- and post-operative cognitive assessment is infrequently performed.

Purpose of the Study:

• To evaluate the cognitive impact of endoscopic colloid cyst resection.
• To determine if colloid cysts contribute to cognitive deficits.
• To assess the utility of neuropsychological testing in monitoring surgical outcomes.

Main Methods:

• Formal neuropsychological testing was administered to 20 patients before and after endoscopic cyst resection.
• Individual patient performance and aggregated factor scores were compared.
• Significant change was defined as statistically significant and exceeding 1.5 standard deviations.

Main Results:

• No patient exhibited significant cognitive performance changes post-surgery.
• Cognitive metrics for temporal, extratemporal, occipitoparietal, and frontal lobes remained stable.
• No significant differences were observed in attention, executive function, language, or visuospatial domains.

Conclusions:

• Endoscopic resection of third ventricle colloid cysts is safe regarding cognitive function.
• Neuropsychological testing is a valuable tool for monitoring cognitive status and surgical outcomes.
• This study found no evidence of cognitive decline associated with colloid cysts or their resection.
