Abstract
Background: Traumatic Brain Injury (TBI) is a risk factor for epilepsy. Several studies have been conducted to estimate the incidence of epilepsy
after TBI. Similarly cognitive impairment is a common consequence of TBI and a substantial source of disability.
Aims: To study the incidence of epilepsy and cognitive impairment following TBI and correlate the findings with radiological abnormalities.
Method: The study was conducted on 50 consecutive patients with TBI based on the assessment of clinical history for epilepsy and MMSE for
cognitive impairment.
Results: The incidence of epilepsy after TBI was found to be 40% in our study. It was increased to 50% among the individuals with radiological
abnormality on CT scan brain following TBI. Cognitive impairment was found to be highest in individuals with frontal lobe injury (mean MMSE score
– 24.13) followed by temporal lobe injury (mean MMSE score – 25.25) and parietal lobe injury (mean MMSE score 26.28). Individuals with no
radiologically detectable injury had least cognitive impairment (mean MMSE score - 27.97) Moreover, cognitive impairment was more in individuals
with higher number of days in hospital and greater psychological distress.
Conclusion: Severity of TBI and presence of radiological abnormality influence new onset epilepsy after TBI. Similarly, injury to frontal lobe and
higher number of days in hospital influence cognitive impairment after TBI.
