Early and late seizures after cryptogenic ischemic stroke in young adults (original) (raw)

Neurology, 2003

Abstract

Objectives: To assess the incidence and predictive factors of early and late seizures after ischemic stroke in young adults.Methods: A total of 581 patients (aged 18 to 55 years) with recent cryptogenic ischemic stroke were prospectively enrolled at 30 neurology departments and followed for 37.8 ± 9.7 months. Early seizures (occurring within 7 days of stroke) were assessed by chart review and late seizures were prospectively recorded at each follow-up visit. Clinical and brain imaging findings were reviewed by two neurologists and two neuroradiologists who were blinded to the occurrence of seizures.Results: Fourteen of the 581 patients (2.4%) developed early seizures, 71% of which occurred within the first 24 hours. Rankin scale ≥3 (odds ratio [OR] 3.9, 95% CI 1.2 to 12.7) and cortical involvement (OR 7.7, 95% CI 1.0 to 61.1) were independently associated with early seizures. Late seizures occurred only in patients with hemispheric stroke (n = 20). The risk of first late seizure was...
