Predictive Risk Factors for Early Seizures in Traumatic Brain Injury

Area of Science:

• Neuroscience
• Trauma Surgery
• Epidemiology

Background:

• Early posttraumatic seizures (PTS) are a major cause of poor outcomes following traumatic brain injury (TBI).
• Understanding the incidence and predictors of early PTS is crucial for improving patient management.
• This study aimed to investigate early PTS incidence and develop a predictive model.

Purpose of the Study:

• To determine the incidence of early posttraumatic seizures (PTS) in traumatic brain injury (TBI) patients.
• To identify significant predictors for early PTS using multivariable logistic regression.
• To develop and validate a predictive nomogram for early PTS.

Main Methods:

• Prospective cohort study involving 484 TBI patients.
• Evaluation of seizure activity within 7 days post-injury.
• Statistical analysis including univariate and multivariable logistic regression, with AUROC curve for model discrimination.

Main Results:

• The incidence of early PTS was 5.6% (27 patients).
• Significant predictors identified were chronic alcohol use (OR: 4.06), epidural hematoma (OR: 3.98), and Glasgow Coma Scale score 3-8 (OR: 3.78).
• The predictive model demonstrated good discrimination with an AUROC of 0.77.

Conclusions:

• Chronic alcohol use, epidural hematoma, and severe TBI are significant predictors of early PTS.
• The developed nomogram serves as a reliable tool for predicting early PTS in individual TBI patients.
• These findings can aid in early identification and management of high-risk TBI patients to prevent seizures.
