title: Clinical approach to posttraumatic epilepsy.
abstract: Traumatic brain injury (TBI) is one of the most common causes of acquired epilepsy, and posttraumatic epilepsy (PTE) results in significant somatic and psychosocial morbidity. The risk of developing PTE relates directly to TBI severity, but the latency to first seizure can be decades after the inciting trauma. Given this "silent period," much work has focused on identification of molecular and radiographic biomarkers for risk stratification and on development of therapies to prevent epileptogenesis. Clinical management requires vigilant neurologic surveillance and recognition of the heterogeneous endophenotypes associated with PTE. Appropriate treatment of patients who have or are at risk for seizures varies as a function of time after TBI, and the clinician's armamentarium includes an ever-expanding diversity of pharmacological and surgical options. Most recently, neuromodulation with implantable devices has emerged as a promising therapeutic strategy for some patients with refractory PTE. Here, we review the epidemiology, diagnostic considerations, and treatment options for PTE and develop a roadmap for providers encountering this challenging clinical entity.
