Despite the availability of more than 20 antiseizure medications (ASMs), there is no way at present to prevent epileptogenesis in TBI survivors, and many cases of PTE become drug-resistant. Importantly, the adverse effects of ASMs can significantly affect patients' quality of life. Mammalian models are commonly used for studying refractory PTE, but are expensive and laborious. Zebrafish models have become popular for studying epilepsy, but most focus on larvae, and there have been no reports to date of pharmacological screening in an adult zebrafish model of acquired epilepsy. Valid animal models are critical for understanding PTE and for developing novel therapeutics. The aim of the present study was to characterize the cognitive impairments of a zebrafish model of TBI that leads to the development of PTE. Using combined behavioral and electrophysiological approaches, we also characterized the pharmacological effects of the most commonly used ASMs to manage PTE (valproate, carbamazepine, and phenytoin). Zebrafish with PTE exhibited impairments in learning and memory, difficulty in decision making, and reduced social preference. Valproate and carbamazepine had a limited protective effect against behavioral seizures, and all three drugs failed to significantly reduce electrographical seizures. The negative impacts of TBI and ASMs in zebrafish parallel those observed in other animals, making the zebrafish model of PTE a promising high-throughput model of refractory and drug-resistant epilepsy.<\/jats:p>","DOI":"10.1089\/neu.2021.0156","type":"journal-article","created":{"date-parts":[[2021,8,19]],"date-time":"2021-08-19T06:13:31Z","timestamp":1629353611000},"page":"3174-3183","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Post-Traumatic Epilepsy in Zebrafish Is Drug-Resistant and Impairs Cognitive Function"],"prefix":"10.1177","volume":"38","author":[{"given":"Sung-Joon","family":"Cho","sequence":"first","affiliation":[{"name":"Division of Fundamental Neurobiology, Krembil Research Institute, University Health Network, Toronto, Ontario, Canada."},{"name":"Collaborative Program in Neuroscience, Departments of University of Toronto, Toronto, Ontario, Canada."},{"name":"Keenan Research Center, Li Ka Shing Knowledge Institute, St. Michael's Hospital, Toronto, Ontario, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eugene","family":"Park","sequence":"additional","affiliation":[{"name":"Keenan Research Center, Li Ka Shing Knowledge Institute, St. Michael's Hospital, Toronto, Ontario, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Baker","sequence":"additional","affiliation":[{"name":"Keenan Research Center, Li Ka Shing Knowledge Institute, St. Michael's Hospital, Toronto, Ontario, Canada."},{"name":"Anesthesia and Surgery, University of Toronto, Toronto, Ontario, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aylin Y.","family":"Reid","sequence":"additional","affiliation":[{"name":"Division of Fundamental Neurobiology, Krembil Research Institute, University Health Network, Toronto, Ontario, Canada."},{"name":"Medicine, University of Toronto, Toronto, Ontario, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,11,2]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.nbd.2018.08.007"},{"key":"e_1_3_3_3_2","article-title":"Migraine and traumatic brain injury: a cohort study in Taiwan","volume":"9","author":"Wang Q.","year":"2019","unstructured":"Wang Q., , Lu Y., , Su Y., , Qin H., , Zhang L., , Wu M.K., , Zhang C.L., , and Wu C.H.
