A small number of studies have reported that adult females who struggled with severe and relapsing AN experienced sustained remission of the illness following ketamine infusions. Two other reports showed that 30\u00a0mg\/kg IP ketamine can reduce vulnerability of adolescent mice to activity\u2010based anorexia (ABA), an animal model of AN. However, no study has tested the efficacy of ketamine on adult ABA mice. This study aimed to fill this gap in knowledge.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Forty\u2010one female mice underwent three cycles of ABA (ABA1, ABA2, and ABA3) to assess relapse vulnerability in adulthood. Of them, 13 received ketamine injections (30\u00a0mg\/kg, 3 doses) during ABA2 (KET) in adulthood to assess ketamine's acute effects during ABA2 and ketamine's potential for sustained efficacy during ABA3, 10\u201313 days later. The remaining 28 received vehicle or no injections during ABA2 (CON).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Severe weight loss (&gt;20% of baseline) during ABA3 was observed for 89% of CON but only 69% of KET. Overall wheel running per day was significantly less for KET than CON (<jats:italic>p<\/jats:italic> &lt; 0.01) throughout ABA2, including hours of food availability, and these reductions were sustained through ABA3. Food consumption was not altered significantly by ketamine.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>These findings suggest that ketamine may reduce adult females\u2019 vulnerability to ABA and may protect women from AN relapse by reducing hyperactivity.<\/jats:p><\/jats:sec>","DOI":"10.1002\/syn.70005","type":"journal-article","created":{"date-parts":[[2025,1,3]],"date-time":"2025-01-03T15:44:58Z","timestamp":1735919098000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Subanesthetic Ketamine Ameliorates Activity\u2010Based Anorexia of Adult Mice"],"prefix":"10.1002","volume":"79","author":[{"given":"Yiru","family":"Dong","sequence":"first","affiliation":[{"name":"Center for Neural Science New York University  New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4010-9425","authenticated-orcid":false,"given":"Chiye","family":"Aoki","sequence":"additional","affiliation":[{"name":"Center for Neural Science New York University  New York New York USA"},{"name":"Neuroscience Institute, NYU Langone Medical Center New York University  New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,3]]},"reference":[{"key":"e_1_2_11_2_1","volume-title":"Animal Models of Eating Disorders","author":"Aoki C.","year":"2020"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnbeh.2022.990354"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1001\/archgenpsychiatry.2011.74"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.4088\/JCP.v65n1106"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pscychresns.2014.10.013"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/1098-108X(199401)15:1<21::AID-EAT2260150104>3.0.CO;2-K"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.20164"},{"key":"e_1_2_11_10_1","volume-title":"Sequenced Ketogenic Diet and Ketamine Infusions for Chronic Anorexia: A Pilot Study","author":"Calabrese L.","year":"2022"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40519\u2010022\u201001455\u2010x"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/mp.2015.176"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0041851"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mcn.2018.04.008"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22937"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroscience.2013.03.020"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psc.2019.01.007"},{"key":"e_1_2_11_18_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyt.2014.00014"},{"key":"e_1_2_11_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0010-440X(97)90927-5"},{"key":"e_1_2_11_20_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005053-199906000-00002"},{"key":"e_1_2_11_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2009.09.009"},{"key":"e_1_2_11_22_1","doi-asserted-by":"publisher","DOI":"10.1523\/ENEURO.0025\u201018.2018"},{"key":"e_1_2_11_23_1","unstructured":"Dong Y. andC.Aoki.2024.Ketogenic Diet Reduces Activity\u2010Based Anorexia (ABA) Vulnerability of Adult Mice by Minimizing Wheel Activity and Weight Fluctuation.
