The etiology of U-MMD is unknown, it accounts for 9.7\u201317.8% of all moyamoya disease, and the family incidence is 5.5\u201313.3%. The clinical characteristics are similar to those of typical moyamoya disease, but there are some differences. U-MMD can progress to bilateral moyamoya disease with a median probability of 29.01% (ranging from 6.3 to 58.8%), and there are many risk factors that promote its development. Surgical treatment can effectively reduce the incidence of ischemic stroke and improve prognosis. However, the timing and indications for surgery require further investigation. This article reviews the latest research progress on the etiology, epidemiology, clinical and radiological characteristics, progression, treatment, and prognosis of U-MMD.<\/jats:p>","DOI":"10.3389\/fnhum.2025.1503639","type":"journal-article","created":{"date-parts":[[2025,1,27]],"date-time":"2025-01-27T06:42:18Z","timestamp":1737960138000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Research progress in unilateral moyamoya disease"],"prefix":"10.3389","volume":"19","author":[{"given":"Xiaokuan","family":"Hao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cunxin","family":"Tan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziqi","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Tie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanru","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shihao","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ran","family":"Duan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,1,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1012","DOI":"10.1111\/ene.12702","article-title":"Distinct clinical and radiographic characteristics of moyamoya disease amongst European Caucasians","volume":"22","author":"Acker","year":"2015","journal-title":"Eur.
