Primary Objective:
To identify risk factors for intracerebral lesion (ICL) in older adults with mild traumatic brain injury (MTBI) and evaluate the influence of comorbidities on outcomes.
Research Design:
Prospective cohort study.
Methods And Procedures:
Information was gathered on clinical history/examination, cranial computed tomography, admission Glasgow Coma Scale (GCS) score, analytical and coagulation findings, and mortality at 1 week post-discharge. Bivariate and multivariate logistic regression analyses were performed, calculating odds ratios for ICL with 95% confidence interval. P < 0.05 was considered significant.
Main Outcomes And Results:
Data were analyzed on 504 patients with mean±SD age of 79.37 ± 8.06 years. Multivariate analysis showed that traffic accident, GCS score of 14/15, transient consciousness loss, nausea, and receipt of antiplatelets were predictors of ICL, while SRRI and/or benzodiazepine intake was a protective factor. A score was assigned to patients by rounding OR values, and a score ≥1 indicated moderate/high risk of ICL.
Conclusions:
MTBI management should be distinct in over-60 year-olds, who may not present typical symptoms, with frequent comorbidities. Knowledge of risk factors for post-MTBI ICL, associated with higher mortality, is important to support clinical decision-making. Further research is warranted to verify our novel finding that benzodiazepines and/or SSRI inhibitors may act as neuroprotectors.
