In a study of 256 patients with moderate-to-severe traumatic brain injury (TBI), researchers showed that higher cerebral spinal fluid and serum interleukin- 1beta (IL-1β) ratios were associated with increased risk of posttraumatic epilepsy (PTE). This is the first report of its type and results provide evidence that biologic variability with blood-brain barrier integrity during recovery from TBI could be attributed to genetic and IL-1β genetic and ratio associations with PTE. Further studies are needed to confirm these findings.
