Objective: No systematic reviews could be identified in the literature that address ADHD research in Arab countries. In an attempt to help fill this gap, this systematic review was undertaken. Method: An electronic literature search of ADHD studies carried out in Arab countries was done by using Google Scholar, PsycINFO, PubMed, Education Resources Information Center (ERIC), and Arabpsynet. Results: The search yielded 58 studies (10 studies on psychoeducational and social aspects of ADHD, 26 prevalence studies and two reviews of epidemiology of ADHD, and 22 studies on risk factors and comorbidities in ADHD). Conclusion: Although there has been an increase in ADHD research in Arab countries in recent years, this research remains relatively sparse and used methods and procedures that limit the generalizability of the findings.
