Risk Factors for Epilepsy after Traumatic Brain Injury

Epilepsy Res; ePub 2018 Aug 23; DeGrauw et al.


 

Among patients who have experienced a traumatic brain injury (TBI), the likelihood of developing post-traumatic epilepsy (PTE) increases with age, the early onset of seizures, and the severity of the brain injury, according to an analysis of insurance claims from 2004 to 2014.

  • There were approximately 2.8 million emergency room visits, hospitalizations and deaths from traumatic brain injuries in the US in 2013.
  • Early seizures occurred in 0.5% of patients with TBI.
  • Over a 9 year period, the incidence of post-traumatic epilepsy (PTE) increased from 1 to 4% in this population.
  • Early onset of seizures, older age, and TBI severity increased the likelihood of PTE.
  • Prophylactic acetazolamide seemed to reduce the risk of PTE, when compared to patients who had received no anti-epilepsy drugs.
