Prevalence of Adult Attention Deficit Hyperactivity Disorder among Medical Students, King Faisal University

Background: The neurobehavioral disorder known as attention-deficit/hyperactivity disorder (ADHD) is typified by impulsivity, hyperactivity, and difficulty in maintaining focus. According to recent research, it can last into adulthood. Regarding identifying adult ADHD, the fifth edition of the "Diagnostic and Statistical Manual of Mental Disorders" has undergone major alteration. As far as we are aware, few research has been done in the Gulf region on adult ADHD among medical students.Method: A cross-sectional study was carried out on students of medicine from all academic years in King Faisal University, Hofuf, from December 2023 until June 2024. 279 medical students participated in the study. Self-reported English questionnaires with two sections—a sociodemographic section and a screening scale for adult ADHD based on the DSM5 version—were utilized for the investigation. Outcomes: (14. %) of pupils mentioned having signs of ADHD. Results: Of the sample, 14% of students exhibited ADHD symptoms, a rate higher than the global prevalence. Female students (13.1%) and first-year students (18.9%) showed significant ADHD symptoms. Psychological comorbidities were present in 28.6% of ADHD-affected students compared to 11.4% of non-affected students. The ADHD group demonstrated mild but notable challenges in concentration, relaxation, and impulsive behavior, with implications for academic performance and stress management.Conclusion: Our study shows a higher prevalence compared with a worldwide prevalence of i.e., 14%. This difference could be due to community interaction and way of living life style factors. Those individuals may have difficulty in communication and learning which can disturb students’ academic efficiency, lengthen their study, and even disturb their development.
