In 1998, Zeman et al. proposed the following diagnostic criteria for TEA: (1) recurrent, witnessed episodes of amnesia (TEA attacks); (2) other cognitive functions remain intact during attacks; and (3) evidence of epilepsy. It was also reported that patients with TEA often demonstrate two other types of memory symptoms: accelerated long\u2010term forgetting (ALF) and autobiographical amnesia (AbA). Both ALF and AbA are persistent memory disorders, but transient epileptic seizures are not.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We encountered two cases of TEA associated with two types of amnesia attacks. Therefore, we reviewed TEA cases in the literature to clarify the type of TEA attacks that occurred.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Based on the extracted TEA cases, including our two cases, we found that there are two main types of TEA attacks, and we discussed their clinical features.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We propose two main types of TEA attacks; that is, pure amnesia\u2010type and partial amnesia\u2010type seizures. Furthermore, we also propose that topographical amnesia mainly manifests as a type of amnesia attack, rather than as a chronic memory disturbance, such as ALF or AbA.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pcn5.114","type":"journal-article","created":{"date-parts":[[2023,6,24]],"date-time":"2023-06-24T23:34:57Z","timestamp":1687649697000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Classification of transient epileptic amnesia attacks: Two types of amnestic seizures, the pure amnesia type and partial amnesia type"],"prefix":"10.1002","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7649-2238","authenticated-orcid":false,"given":"Katsuyuki","family":"Ukai","sequence":"first","affiliation":[{"name":"Department of Psychogeriatrics Kamiiida Daiichi General Hospital Nagoya Japan"},{"name":"Department of Psychiatry Nagoya University Graduate School of Medicine Nagoya Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masumi","family":"Ito","sequence":"additional","affiliation":[{"name":"Jozen Neuro Clinic Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masako","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Shinjuku Neuro Clinic Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,6,23]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.53.10.834"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.56.11.1184"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.64.4.435"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2004.036582"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.21111"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/psyg.12753"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/115.3.749"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1053\/seiz.2001.0587"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1528-1167.2006.00704.x"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocn.2010.03.005"},{"key":"e_1_2_13_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/epi.12565"},{"key":"e_1_2_13_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.yebeh.2014.04.014"},{"key":"e_1_2_13_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.seizure.2014.07.008"},{"key":"e_1_2_13_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.seizure.2016.10.022"},{"key":"e_1_2_13_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cortex.2017.09.007"},{"key":"e_1_2_13_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/epi.17214"},{"key":"e_1_2_13_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/epi4.12040"},{"key":"e_1_2_13_19_1","first-page":"189","article-title":"Elderly\u2010onset epilepsy in memory clinic: discrimination and association with dementia","volume":"21","author":"Shiozaki K","year":"2019","journal-title":"Ninchi Shinkei Kagaku"},{"key":"e_1_2_13_20_1","first-page":"165","article-title":"Epileptic amnesia","volume":"31","author":"Shiozaki K","year":"2020","journal-title":"Rounen Seishin Igaku Zasshi"},{"key":"e_1_2_13_21_1","doi-asserted-by":"publisher","DOI":"10.1093\/braincomms\/fcab038"}],"container-title":["Psychiatry and Clinical Neurosciences Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/pcn5.114","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,20]],"date-time":"2024-01-20T13:50:27Z","timestamp":1705758627000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/pcn5.114"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,6]]},"references-count":20,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2023,6]]}},"alternative-id":["10.1002\/pcn5.114"],"URL":"https:\/\/doi.org\/10.1002\/pcn5.114","archive":["Portico"],"relation":{},"ISSN":["2769-2558","2769-2558"],"issn-type":[{"value":"2769-2558","type":"print"},{"value":"2769-2558","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,6]]},"assertion":[{"value":"2023-03-30","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-06-05","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-06-23","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e114"}}
