The study focused on understanding the prevalence and clinical characteristics of ADHD in adult patients at a hospital in Oman over a 5-year period.
Out of nearly 40,000 hospital visits, 1.77% were by adults with ADHD, with the highest prevalence observed in 2021 and more cases among men, particularly those under 20.
The findings highlight that inattention was the most common subtype of ADHD, and the study adds valuable insights into how ADHD manifests in adult populations compared to other psychiatric conditions.
