Study outcome was the occurrence of drug resistance defined as failure of adequate trials of two tolerated and appropriately chosen and used antiseizure medication schedules to achieve sustained seizure freedom.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred fifty\u2010nine patients with PSE and a median follow\u2010up of 5 (interquartile range [IQR]\u00a0=\u00a03\u20139) years were included. In the study cohort, 29 (18.2%) participants were drug resistant. The median length of the time interval between stroke and PSE onset was 13 (IQR\u00a0=\u00a07\u201315) months in drug\u2010resistant patients and 19 (IQR\u00a0=\u00a014\u201342) months (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.001) in patients with seizure control. According to multivariable regression analysis, the time from stroke to PSE was an independent predictor of drug resistance (<jats:italic>p<\/jats:italic>\u00a0&lt;\u20090.001). The risk of drug resistance was highest when the onset of PSE occurred within the first months from stroke and decreased progressively with a steeper decline over the first
