Presurgical evaluation
Comprehensive assessment to determine surgical candidacy for patients with medication-resistant epilepsy.
Full Definition
Presurgical evaluation is a systematic process involving multiple diagnostic modalities to localize the seizure focus and assess surgical risks in patients with pharmacoresistant epilepsy. The evaluation typically includes prolonged video-EEG monitoring, high-resolution MRI, neuropsychological testing, and functional imaging studies. The goal is to identify patients who may benefit from epilepsy surgery while minimizing risks to critical brain functions such as language and memory.
Usage
Usage note: Hyphenate when used as an adjective; distinguish from general preoperative assessment.
