This systematic review and meta\u2010analysis examined dementia prevalence across MENA. Databases were searched up to October 2024. Analyses were stratified by country and sex. Pooled prevalence was estimated using a random\u2010effects model with a 95% confidence interval (CI). Fifty\u2010two studies on the selected countries met inclusion criteria, covering 87,219 individuals with dementia from a total population of 1,045,908. The pooled prevalence was 12.16% (95% CI: 9.61\u201314.96) for the region and the Israel had the highest prevalence (17.00%), followed by Iran (13.20%), Turkey (11.40%), Saudi Arabia (8.34%), and Egypt (6.86%). Dementia was more common in women than men (13.84%\u00a0vs. 8.69%). Dementia is prevalent in MENA, with significant variation across countries. The region's aging population highlights the need for ongoing monitoring of dementia trends.<\/jats:p>","DOI":"10.1002\/alz.71109","type":"journal-article","created":{"date-parts":[[2026,1,29]],"date-time":"2026-01-29T03:36:50Z","timestamp":1769657810000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Prevalence of dementia in selected Middle East and North Africa (MENA) countries: A systematic review and meta\u2010analysis"],"prefix":"10.1002","volume":"22","author":[{"given":"Mohsen","family":"Sedighi","sequence":"first","affiliation":[{"name":"Trauma and Injury Research Center Iran University of Medical Sciences  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Hasan","family":"Shahabi","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Psychotherapy University of Marburg  Marburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alireza","family":"Amanollahi","sequence":"additional","affiliation":[{"name":"Trauma and Injury Research Center Iran University of Medical Sciences  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khurshid","family":"Alam","sequence":"additional","affiliation":[{"name":"Murdoch Business School, Murdoch University  Murdoch WA Australia"},{"name":"Centre for Healthy Ageing Health Futures Institute Murdoch University Murdoch WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soudabeh","family":"Shemehsavar","sequence":"additional","affiliation":[{"name":"Centre for Healthy Ageing Health Futures Institute Murdoch University Murdoch WA Australia"},{"name":"College of Science Technology Engineering and Mathematics Murdoch University  Murdoch WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zahra","family":"Shirzadi","sequence":"additional","affiliation":[{"name":"Department of Neurology Massachusetts General Hospital, Harvard Medical School  Boston Massachusetts USA"},{"name":"Medical &amp; Scientific Relations, Alzheimer's Association  Chicago Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serena","family":"Sabatini","sequence":"additional","affiliation":[{"name":"Department of Clinical Psychology and Psychobiology University of Barcelona  Barcelona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmad R.","family":"Khatoonabadi","sequence":"additional","affiliation":[{"name":"School of Rehabilitation Speech Therapy Department Tehran University of Medical Sciences  Tehran Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Prina","sequence":"additional","affiliation":[{"name":"Population Health Sciences Institute Newcastle University  Newcastle UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akram A.","family":"Hosseini","sequence":"additional","affiliation":[{"name":"Department of Academic Neurology Queen's Medical Centre, Nottingham University Hospitals NHS Trust  Nottingham UK"},{"name":"Sir Peter Mansfield Imaging Centre University of Nottingham  Nottingham UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claire V.","family":"Burley","sequence":"additional","affiliation":[{"name":"Dementia Centre of Excellence, enAble Institute Curtin University  Perth WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Dunne","sequence":"additional","affiliation":[{"name":"Dementia Centre of Excellence, enAble Institute Curtin University  Perth WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simin","family":"Mahinrad","sequence":"additional","affiliation":[{"name":"Medical &amp; Scientific Relations, Alzheimer's Association  Chicago Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iman","family":"Dajani","sequence":"additional","affiliation":[{"name":"Weill Cornell Medicine Qatar Qatar Foundation  Education City Doha Qatar"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralph N.","family":"Martins","sequence":"additional","affiliation":[{"name":"Centre for Healthy Ageing Health Futures Institute Murdoch University Murdoch WA Australia"},{"name":"School of Medical and Health Sciences Edith Cowan University  Joondalup WA Australia"},{"name":"Macquarie Medical School Macquarie University  New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blossom C.
