Methods: We analyzed prospectively collected data of 12 patients referred to our department from 2004 to 2019. All patients underwent a thorough diagnostic work up, including extensive clinical, neuroradiological, and neurocognitive assessment. Results: Our study population consisted of 7 females and the median age at the time of the diagnosis was 43.5 years. No patient had a positive family history of the disease and roughly 50% were hypertensives. Ten patients presented with transient or permanent cerebrovascular ischemia and two patients suffered from hemorrhagic complications. The median NIHSS was 7.5 (0\u201323) and clinical status remained stable during follow-up with conservative treatment in most of the patients. The majority (83.3%) had bilateral disease confirmed by DSA. All lesions exclusively affected the anterior circulation, with 50% of patients presenting with stenoocclusive changes. No aneurysm or AVM were revealed. The most common neurocognitive deficits were in the executive and language domains. Conclusions: Our MMD patients had a later onset of the disease and an absence of familial occurrence. The most common manifestation was ischemia, transient or permanent, and all lesions affected the anterior circulation, whereas no vascular malformations (AVM, aneurysms) were demonstrated in brain imaging. These findings in Greek patients imply a probable different, Mediterranean phenotype.<\/jats:p>","DOI":"10.3390\/jcm12185951","type":"journal-article","created":{"date-parts":[[2023,9,14]],"date-time":"2023-09-14T10:09:22Z","timestamp":1694686162000},"page":"5951","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Moyamoya Disease: Clinical and Radiological Characteristics in Adult Greek Patients"],"prefix":"10.3390","volume":"12","author":[{"given":"Sofia","family":"Vassilopoulou","sequence":"first","affiliation":[{"name":"Stroke Unit, 1st Department of Neurology, Eginition Hospital, National and Kapodistrian University of Athens, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3276-588X","authenticated-orcid":false,"given":"Argyro","family":"Tountopoulou","sequence":"additional","affiliation":[{"name":"Stroke Unit, 1st Department of Neurology, Eginition Hospital, National and Kapodistrian University of Athens, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eleni","family":"Korompoki","sequence":"additional","affiliation":[{"name":"Stroke Unit, 1st Department of Neurology, Eginition Hospital, National and Kapodistrian University of Athens, 11528 Athens, Greece"},{"name":"Department of Clinical Therapeutics, National and Kapodistrian University of Athens, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgios","family":"Papageorgiou","sequence":"additional","affiliation":[{"name":"Neuropsychology and Language Disorders Unit, Eginition Hospital, National and Kapodistrian University of Athens, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6324-0384","authenticated-orcid":false,"given":"Dimitrios","family":"Kasselimis","sequence":"additional","affiliation":[{"name":"Neuropsychology and Language Disorders Unit, Eginition Hospital, National and Kapodistrian University of Athens, 11528 Athens, Greece"},{"name":"Department of Psychology, Panteion University of Social and Political Sciences, 17671 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0050-284X","authenticated-orcid":false,"given":"Georgios","family":"Velonakis","sequence":"additional","affiliation":[{"name":"2nd Department of Radiology, National and Kapodistrian University of Athens, 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Achilles","family":"Chatziioannou","sequence":"additional","affiliation":[{"name":"1st Department of Radiology, National and Kapodistrian University of Athens, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Constantin","family":"Potagas","sequence":"additional","affiliation":[{"name":"Neuropsychology and Language Disorders Unit, Eginition Hospital, National and Kapodistrian University of Athens, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantinos","family":"Spengos","sequence":"additional","affiliation":[{"name":"Department of Neurology, Hygeia Hospital, 15123 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"826","DOI":"10.1161\/01.STR.19.7.826","article-title":"Cerebral infarction due to moyamoya disease in young adults","volume":"19","author":"Bruno","year":"1988","journal-title":"Stroke"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"53","DOI":"10.1161\/01.STR.19.1.53","article-title":"Moyamoya disease in Taiwan","volume":"19","author":"Chen","year":"1988","journal-title":"Stroke"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"52","DOI":"10.1016\/j.clineuro.2016.11.017","article-title":"Movement symptoms in European Moyamoya angiopathy\u2014First systematic questionnaire study","volume":"152","author":"Kraemer","year":"2017","journal-title":"Clin.
