Frequency of post-stroke electroencephalographic epileptiformactivity – a systematic review and meta-analysis of observationalstudies

Although electroencephalography is the gold standard epilepsy biomarker, it is rarely used in post-stroke studies, and the frequency of post-stroke epileptiform activity is still uncertain.
