Seizure‐related injuries in people with epilepsy: A cohort study from Saudi Arabia

OBJECTIVES: Patients with epilepsy have a high risk of accidents and injuries, resulting in minimized physical activity and social withdrawal. Therefore, we surveyed the prevalence and the types of injuries that patients with epilepsy may endure, and the factors that may increase the risk of injuries. METHODS: In this cohort study, adult and pediatric patients diagnosed with epilepsy (age ≥ 7 years) and a close family member (parents/guardian) attending the outpatient epilepsy clinics at King Fahd Medical City (Riyadh, Saudi Arabia) were interviewed by neurologists. They reviewed the patients' medical records and administered a structured questionnaire to identify and compare several variables, including injury frequency versus seizure type and seizure frequency, number of antiseizure medications used, medication compliance, and work and social limitations. RESULTS: Out of 200 patients, 86 (43%) sustained injuries during an attack of their habitual seizures. Almost half of this group showed a tendency for recurrent injuries. The most common traumas were soft tissue injury (36.5%), head injury (32%), dental injury (8.5%), burns (7%), dislocation (7%), fractures (6.5%), and submersion (2%). Two‐thirds of the patients had their injury at home. 64% of patients who had seizures for more than 10 years sustained multiple injuries (P = .003). Injury frequency was higher among patients with daily or monthly seizures (P = .03). 76% of patients who suffered injuries more than twice had generalised tonic‐clonic seizures, and genetic generalised epilepsy was encountered more in injured patients (P = .02). Also, patients on polytherapy were more likely than those on monotherapy to have an injury (P = .003). SIGNIFICANCE: Two‐fifths of the patients reported seizure‐related injuries. The most common were soft‐tissue injuries and head traumas, while homes were the most frequent site. In addition, longer epilepsy duration, generalized tonic‐clonic seizures, and polytherapy were associated with a higher prevalence of injuries. Therefore, injury prevention strategies should be developed for PWE, especially for those at higher risk.
