Core Tip

Core Tip: This narrative review comprehensively explores the wide range of medical, psychiatric, neurological, and behavioral co-occurring conditions (CCs) in individuals with autism. Authored by experts in the field, it synthesizes current evidence and clinical insight to support early recognition and integrated care. Notably, such an extensive and multidisciplinary review of autism CCs has not been previously published, addressing a significant gap in the literature.
