I read with great interest the article by Lahti et al. on the incidence of poststroke epilepsy (PSE) in 615 ICH survivors, out of whom 13% developed poststroke epilepsy during a median follow-up of 6.4 years. [1] The article is very interesting and in line with the emerging notion that PSE is more common than previously thought. However, the authors were mistaken in their statement that long-term incidence of PSE after ICH had not been previously investigated.
In 2016, we published a register-based cohort study on all patients with stroke in 2005-2015 Sweden. [2] The cohort included 10,195 patients with ICH, out of whom 12.4% developed PSE over a median follow-up time of 4.8 years. Since Lahti et al. used different methodology and arrived at a very similar result, the two studies--both performed in Nordic countries--seem to provide good estimates of long-term risk of PSE. In addition, Lahti et al. were able to provide valuable information on risk factors of PSE after ICH. [1]
