Resume

Electroencephalography (EEG) plays a critical role in assessing functional brain disturbances associated with intracranial tumors. The present study investigates the correlation between various EEG abnormalities and postoperative neurological complications in 100 patients with histologically confirmed brain tumors. Preoperative and postoperative EEG recordings were analyzed in relation to clinical outcomes, including seizure activity, motor deficits, visual disturbances, and cognitive decline. Specific EEG patterns, particularly epileptiform discharges and reduced alpha reactivity, demonstrated strong prognostic value. Epileptiform discharges were significantly associated with postoperative seizure risk, while impaired alpha reactivity correlated with visual deficits and poorer cognitive outcomes. Theta–delta predominance and diffuse slowing were also linked to motor and cognitive impairments, highlighting the differential prognostic significance of distinct EEG abnormalities. These findings underscore the utility of EEG not only as a diagnostic tool but also as a biomarker for predicting postoperative neurological complications. Incorporating EEG parameters into perioperative risk assessment may contribute to personalized patient management and improved rehabilitation strategies. The study emphasizes the need for integrated electrophysiological monitoring in the neurosurgical care pathway for brain tumor patients.
