Seizures after intracerebral hemorrhage; risk factor, recurrence, efficacy of antiepileptic drug

Objective: This study aimed to determine the risk factors for recurrent post stroke seizure (PSS) and the efficacy of anti-epileptic drugs (AED) in patients having intracerebral hemorrhage (ICH) with initial seizure. Methods/subjects: A total of 1920 consecutive patients with ICH from 2004 to 2012 were investigated retrospectively. The relationships among the baseline clinical and radiological data, administration of AED, and incidence of initial and recurrent PSS were evaluated using multiple logistic regression analysis. Results: Seizures occurred in 127(6.6%) of the 1920 patients, displaying statistically significant relationships with cortical involvement of a cerebral lesion (P <0.001), non-hypertensive ICH (P <0.001), younger age (P <0.001), and severe neurological deficits (P <0.001). Early (4.3%) and late seizure (2.3%) had no significant relationship with the development of recurrent PSS. Larger volume of hematoma was the only independent factor associated with recurrence of PSS (OR 1.03; 95% CI 1.00-1.05; P = 0.027). A Kaplan Meier survival analysis revealed that AED treatment had a poor association with recurrence of PSS (P = 0.750). Conclusions: Larger volume of hematoma was predictive of recurrence of PSS. AED therapy had poor association with preventing the recurrence of PSS. (C) 2015 Published by Elsevier B.V.
