This case series described 42 children diagnosed with SSPE and received treatment at a tertiary neurology hospital in Dhaka, Bangladesh, from the year 2019 to 2021. The median age at onset of was 4 years (range: 2.5-11 years), with a mean latent period of 2.68 \u00b1 0.97 (SD) years. While 30 cases (71.4%) were immunized, 23 of these children developed SSPE despite receiving immunization after 9 months of age. Additionally, a small proportion of cases (n = 7) had a history of measles infection prior to the scheduled age of vaccination. Males predominated (88.1%) in this cohort. Clinical presentation typically involved speech and motor regression alongside the myoclonic jerks. These findings point toward an earlier onset and shorter latency period of SSPE in this population which demands further evaluation.<\/jats:p>","DOI":"10.1177\/30502225261453521","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T12:17:05Z","timestamp":1780661825000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Earlier Onset of Subacute Sclerosing Panencephalitis in Bangladeshi Children: Insights from a Case Series"],"prefix":"10.1177","volume":"13","author":[{"given":"Sarah","family":"Alam","sequence":"first","affiliation":[{"name":"National Institute of Neurosciences &amp; Hospital, Dhaka, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yamin Shahriar","family":"Chowdhury","sequence":"additional","affiliation":[{"name":"National Institute of Neurosciences &amp; Hospital, Dhaka, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narayan","family":"Saha","sequence":"additional","affiliation":[{"name":"National Institute of Neurosciences &amp; Hospital, Dhaka, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samsun Nahar","family":"Sumi","sequence":"additional","affiliation":[{"name":"National Institute of Neurosciences &amp; Hospital, Dhaka, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sufia Khatun","family":"Sumi","sequence":"additional","affiliation":[{"name":"National Institute of Neurosciences &amp; Hospital, Dhaka, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4761-2365","authenticated-orcid":false,"given":"Tamanna","family":"Tabassum","sequence":"additional","affiliation":[{"name":"Pi Research &amp; Development Center, Dhaka, Bangladesh"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,5]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/rmv.2058"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.4103\/aian.aian_1112_24"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dym207"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/147323001103900228"},{"key":"e_1_3_3_6_2","first-page":"22","article-title":"Trends and treatment of sub-acute sclerosing panencephalitis: an updated review","volume":"8","author":"Memon SA","year":"2021","unstructured":"Memon SA, Afzal SS, Tukruna A, Khan AT, Tebha SS, Zaidi ZA.
