Brain CT shows central and less peripheral atrophy of brain, and diagnosis of normal pressure hydrocephalus was raised; however, removal of 30 cc of cerebrospinal fluid (CSF) by lumbar puncture in order to amend walking did not lead to gait improvement. After excluding metabolic, vascular, infection, inflammatory and other reasons explaining his status. Thinking that may be any correlation between LEV added in the last months and his clinical condition, we stopped LEV. Several days after that, there is marked improvement in his general sensation, alertness and cognitive status and there is marked improvement in walking balance to the point of being able to walk without the use of walker or cane or help from other person. Certain cognitive impairment and gait difficulties are not known as side effects of LEV treatment.<\/jats:p>","DOI":"10.1136\/bcr-2021-242496","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T03:10:04Z","timestamp":1619493004000},"page":"e242496","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Unusual side effects of levetiracetam"],"prefix":"10.1136","volume":"14","author":[{"given":"Samih","family":"Badarny","sequence":"first","affiliation":[{"name":"Department of Neurology, Galilee Medical Center, Nahariya, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"yazid","family":"Badarny","sequence":"additional","affiliation":[{"name":"Neurosurgery Department, Rambam Medical Center, Haifa, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatima","family":"Mihilia","sequence":"additional","affiliation":[{"name":"Department of Neurology, Galilee Medical Center, Nahariya, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,4,26]]},"reference":[{"key":"2025082800522526000_14.4.e242496.1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(06)70678-0"},{"key":"2025082800522526000_14.4.e242496.2","doi-asserted-by":"publisher","DOI":"10.1212\/CPJ.0b013e31825a7823"},{"key":"2025082800522526000_14.4.e242496.3","doi-asserted-by":"crossref","first-page":"E27","DOI":"10.1212\/01.wnl.0000296051.34044.07","article-title":"Seizure medications and their side effects","volume":"69","author":"Karceski","year":"2007","journal-title":"Neurology"},{"key":"2025082800522526000_14.4.e242496.4","doi-asserted-by":"publisher","DOI":"10.1177\/1756285611417920"},{"key":"2025082800522526000_14.4.e242496.5","doi-asserted-by":"publisher","DOI":"10.1177\/2042098611411127"},{"key":"2025082800522526000_14.4.e242496.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1528-1167.2009.02397.x"},{"key":"2025082800522526000_14.4.e242496.7","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0308208101"},{"key":"2025082800522526000_14.4.e242496.8","doi-asserted-by":"crossref","first-page":"1266","DOI":"10.4103\/0028-3886.193801","article-title":"Levetiracetam as an antiepileptic, neuroprotective, and hyperalgesic drug","volume":"64","author":"Cortes-Altamirano","year":"2016","journal-title":"Neurol India"},{"key":"2025082800522526000_14.4.e242496.9","doi-asserted-by":"publisher","DOI":"10.1111\/epi.13849"},{"key":"2025082800522526000_14.4.e242496.10","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000281104.55418.60"},{"key":"2025082800522526000_14.4.e242496.11","first-page":"1351","article-title":"The KEEPER\u2122 1 trial: levetiracetam adjunctive treatment of partial-onset seizures in an open-label community-based study","volume":"28","author":"Morrell","year":"2003","journal-title":"Epilepsy res"},{"key":"2025082800522526000_14.4.e242496.12","doi-asserted-by":"crossref","first-page":"1772","DOI":"10.1212\/WNL.56.12.1772","article-title":"Long-term continuation of levetiracetam in patients with refractory epilepsy","volume":"56","author":"Krakow","year":"2001","journal-title":"Neurology"},{"key":"2025082800522526000_14.4.e242496.13","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1016\/j.ebcr.2015.07.004","article-title":"Levetiracetam-induced RAGE and suicidality: two case reports and review of literature","volume":"4","author":"Molokwu","year":"2015","journal-title":"Epilepsy Behav Case Rep"},{"key":"2025082800522526000_14.4.e242496.14","doi-asserted-by":"crossref","unstructured":"Ogunsakin O , Tumenta T , Louis-Jean S .
