Abstract

PURPOSE: Patients with epilepsy have a higher risk of accidental injuries. The aim of this study was to determine the incidence of accidental injuries and quality of life in patients with epilepsy and generalized tonic-clonic seizures and their association with patient-related factors.
METHODS: This is an observational, cross-sectional, multicenter study of patients with epilepsy and primary generalized tonic-clonic seizures and/or focal to bilateral tonic-clonic seizures in the routine clinical practice of epilepsy clinics. In a single visit, demographic and clinical data and information on the type and severity of injuries were collected, and patients' quality of life was evaluated with the QOLIE-10 questionnaire.
RESULTS: In total, 406 patients with a median age of 41.1 years (range: 13-87) were included; 47.5% were women. Age at onset of tonic-clonic seizures was 25.4 (range: 0-83) years. Epileptic seizures were primary tonic-clonic (67.2%), focal to bilateral tonic-clonic (32.8%), focal with impairment of awareness (23.6%), focal without impairment of awareness (13.5%), absences (14.8%), and myoclonic (9.6%). Etiology was symptomatic or with unknown etiology focal (42.9%), genetic generalized (36.9%), symptomatic or with unknown etiology generalized (18.0%), and others (2.2%). The number of generalized tonic-clonic seizures in the last 12 months was as follows: 1 (41.9%), 2-5 (42.4%), and >5 (15.8%). Antiepileptic treatment at the time of the visit was monotherapy in 44.1% of the patients. The most commonly used drugs were levetiracetam (45.1%), valproate (20.7%), lamotrigine (20.0%), and perampanel (18.7%). In total, 59.6% of the patients had experienced at least one accidental injury associated with tonic-clonic seizures in the last 12 months, the most common being head injuries (35.5%), dental injuries (4.9%), burns (4.9%), and fractures (3.9%). A total of 25.1% had suffered at least one serious injury. The multiple logistic regression model showed that the factors associated with suffering an injury were the following: etiology (symptomatic or with unknown etiology focal and genetic generalized vs. symptomatic or with unknown etiology generalized, p = 0.0008 and p = 0.0077, respectively), number of seizures in the last year (2-5 vs. 1, p = 0.0115; >5 vs. 1, p = 0.0004), and psychiatric comorbidities (p = 0.0151). Patients with injuries had a worse quality of life than patients without injuries, according to the overall QOLIE-10 score (p = 0.0003).
CONCLUSIONS: More than half of the patients had accidental injuries related with seizures. Symptomatic or with unknown etiology focal epilepsy and genetic generalized epilepsy, >1 seizure in the last year, and concomitant psychiatric disease are the risk factors associated with accidental injuries in patients with tonic-clonic seizures, with the consequent worsening of quality of life.
