Abstract

Highlights: A retrospective study of 234 stroke patients, 141 of which treated with r-tPA. Post stroke seizures rate was 5% vs. 12.6% in the r-tPA treated vs. non treated. 65% decrease in risk found when treated with r-tPA vs other treatments (p < 0.05). Abstract: Purpose: Post stroke seizures are a complication that occur in 5-20% of acute ischemic stroke (AIS) patients, cause a reduction in quality of life and a greater burden on the health system. There is not enough data regarding an association between today's standard of care treatment in AIS: recombinant tissue plasminogen activator (r-tPA) and the risk for post stroke seizures. Our aim in this work is to reveal such a connection. Method: A non-randomized retrospective cohort-controlled study of 234 patients, who were hospitalized with acute ischemic stroke at Kaplan Medical Center in the years 2009-2015 and were divided into two different treatment groups: r-tPA and antiaggregant therapy(n = 141) and antiaggregant therapy only (n = 95) was conducted by us. Information regarding demographics, medical history, nature of the event, including NIHSS values on admission, discharge, and post stroke seizures, were obtained for each group. Follow-up was done for one year. Results: During the year of follow-up, 19 patients (8.1%) of the overall cohort, developed seizures: 12 of them (12.6%) belonged to the control group and 7 (5%) to the study group p < 0.05). Results showed a decrease in the risk for developing seizure when treated with r-tpA, comparing to antiaggregants (odds ratio = 0.64). Conclusion: This study suggests there is an association between r-tPA treatment and reduction of the risk for post stroke seizures.
