Electroencephalogram Predicts Post-operative Delirium

Frontal-temporal EEG During Anesthesia Recovery Predicts Postoperative Delirium in Neurosurgery: a Single-center, Prospective, Observational Study

Important: This information is not medical advice. Talk to your doctor about whether a clinical trial is right for you.

About This Trial

The goal of this observational study is to investigate the predictive value of sub-hairline electroencephalography (EEG) during anesthesia recovery for postoperative delirium (POD). The main question to be answered is: * Can sub-hairline EEG measured during anesthesia recovery serve as a reliable predictor of POD? Adult patients undergoing elective craniotomy and admitted to the ICU will be enrolled. Sub-hairline EEG will be monitored until ICU discharge.

Who May Be Eligible (Plain English)

Who May Qualify: - Age ≥ 18 years - Planned elective neurosurgical surgery - ASA physical status I-II - Signed willing to sign a consent form Who Should NOT Join This Trial: - Known neurological or psychiatric disorders (e.g., epilepsy, Parkinson's disease) - Preoperative cognitive impairment (MMSE score \< 24) - Long-term use of central nervous system drugs (e.g., antidepressants, antipsychotics) - Language barriers - History of craniotomy within the last 12 months - Inability to place frontal-temporal electrodes due to conditions such as frontal skin injury, severe agitation, or a coronal incision for surgery - Pregnant or breastfeeding women Always talk to your doctor about whether this trial is right for you.

Treatments Being Tested

DIAGNOSTIC_TEST

Sub-hairline EEG Monitoring

Participants will receive standard postoperative care as per institutional protocols, including neuromonitoring, delirium screening, and ICU management. The study will not alter or assign any treatments but will analyze the association between sub-hairline EEG parameters and postoperative delirium (POD) outcomes
