The Comparison of Outcome of Traumatic Brain Injury in Left and Right Hemispheres of The Brain

Abstract

Objective:  Using the Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS), this study compares the clinical presentation, surgical requirements, and functional results of unilateral LH versus RH TBI.

Materials & Methods:  Patients with unilateral LH or RH TBI were the subjects of a retrospective observational study. Individuals with bilateral, brainstem, or diffuse axonal injuries were not included. Initial GCS scores, imaging results, surgical procedures, and GOS scores at discharge were among the data gathered. To evaluate the variations in the clinical trajectory between the two groups, a comparison study was conducted.

Results:  The findings showed that patients with RH injuries needed surgery more often than those with LH injuries and had substantially lower first GCS scores. Lower GOS scores at discharge were linked to RH injuries, even if the radiological findings were identical. On the other hand, LH injuries could be found more quickly and easily, which frequently resulted in better results and faster medical treatment. RH deficits' mild, frequently nonverbal character may cause a delay in diagnosis and treatment, which could worsen the prognosis.

Conclusion:  Hemispheric laterality is important for TBI presentation and results. RH injuries are associated with worse healing, most likely because of delayed diagnosis and care. Understanding these hemisphere-specific variations better could facilitate early detection and direct more efficient, customized treatment plans.
