The Saudi National Mental Health Survey revealed that 80% of Saudis with severe mental health disorders do not seek treatment. Considering the strong evidence set out in Saudi national study and the recommendations for future research, this systematic literature review was initiated to examine the most studied neurodevelopmental disorders reported in the Kingdom of Saudi Arabia to explore public knowledge, attitudes, and behaviors. Findings have shown that attention deficit hyperactivity disorder and autism spectrum disorder have been the most studied neurodevelopmental disorders in Saudi Arabia since 2010. However, various groups in Saudi society, including healthcare professionals, medical students, and the general public, lacked knowledge about these health conditions, often leading to stigmatized attitudes and behaviors toward people with attention deficit hyperactivity disorder and autism spectrum disorder. However, demographic data showed that most of the studies were carried out in the Central and Western provinces. More research is needed in all regions of the Kingdom of Saudi Arabia to contribute to the knowledge about mental health conditions of attention deficit hyperactivity disorder and autism spectrum disorder children and their parents to increase knowledge about neurodevelopmental disorders and mental health disorders in the Kingdom of Saudi Arabia, thereby enabling people to rethink their attitudes and behavior.
