Developing therapeutic strategies to target synaptic loss will require human studies that clarify their clinical relevance of these changes. In the current issue, Zakiniaeiz et al. demonstrate that AUD and alcohol consumption are associated with lower synaptic vesicle glycoprotein 2a (SV2A) expression, indexed by regional [\n                    <jats:sup>11<\/jats:sup>\n                    C]UCB-J PET. This is, to our knowledge, the first in vivo evidence of relationships between synaptic density and alcohol use, and, as such, it represents an important step toward understanding how AUD influences brain structure and function. Here, we describe two longstanding clinical issues in the AUD population \u2014 relapse and dementia risk \u2014 and how the results of the present study may guide future investigations of these issues.\n                  <\/jats:p>","DOI":"10.1172\/jci204460","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T18:00:57Z","timestamp":1774980057000},"source":"Crossref","is-referenced-by-count":1,"title":["Synaptic loss in alcohol use disorder: clinical and mechanistic insights from a PET imaging study"],"prefix":"10.1172","volume":"136","author":[{"given":"Sarah K.","family":"Royse","sequence":"first","affiliation":[{"name":"Departments of Radiology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajesh","family":"Narendran","sequence":"additional","affiliation":[{"name":"Departments of Radiology and"},{"name":"Department of Psychiatry, University of Pittsburgh, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"232","published-online":{"date-parts":[[2026,4,1]]},"reference":[{"issue":"2","key":"B1","article-title":"Alcohol and Alzheimer\u2019s Disease-Does Alcohol Dependence Contribute to Beta-Amyloid Deposition, Neuroinflammation and Neurodegeneration in Alzheimer\u2019s Disease?","volume":"52","author":"Venkataraman","year":"2017","journal-title":"Alcohol Alcohol"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2016.03.034"},{"issue":"7","key":"B3","doi-asserted-by":"crossref","DOI":"10.1172\/JCI199989","article-title":"Higher drinking frequency corresponds to lower synaptic density in people with alcohol use disorder","volume":"136","author":"Zakiniaeiz","year":"2026","journal-title":"J Clin Invest"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.3389\/fnins.2022.864514"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.3389\/fnmol.2017.00148"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1126\/scitranslmed.aaf6667"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1016\/j.neurobiolaging.2023.05.003"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1111\/acer.12893"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1159\/000051271"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1007\/BF00294379"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1097\/00005072-199802000-00001"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1177\/0271678X19879230"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1038\/s41398-022-01809-0"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1002\/jnr.23111"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1124\/pharmrev.120.000083"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1016\/j.alcohol.2022.07.005"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1016\/S2468-2667(18)30022-7"},{"issue":"9","key":"B18","first-page":"899","article-title":"Association of smoking and alcohol drinking with dementia risk among elderly men in China","volume":"11","author":"Zhou","year":"2014","journal-title":"Curr Alzheimer Res"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2022.54771"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.1136\/bmjebm-2025-113913"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1002\/jnr.22091"},{"key":"B22","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-190834"},{"key":"B23","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.1003022"},{"key":"B24","doi-asserted-by":"publisher","DOI":"10.1038\/s41398-021-01374-y"},{"key":"B25","doi-asserted-by":"publisher","DOI":"10.1038\/sj.npp.1301219"},{"key":"B26","doi-asserted-by":"publisher","DOI":"10.1016\/j.expneurol.2022.114061"},{"key":"B27","doi-asserted-by":"publisher","DOI":"10.1126\/scisignal.aba5754"}],"container-title":["Journal of Clinical Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.jci.org\/articles\/view\/204460\/files\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,19]],"date-time":"2026-05-19T16:41:59Z","timestamp":1779208919000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jci.org\/articles\/view\/204460"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,1]]},"references-count":27,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2026,2,17]]},"published-print":{"date-parts":[[2026,4,1]]}},"alternative-id":["10.1172\/JCI204460"],"URL":"https:\/\/doi.org\/10.1172\/jci204460","relation":{},"ISSN":["1558-8238"],"issn-type":[{"value":"1558-8238","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,1]]},"article-number":"e204460"}}
