Medical experts discuss links between ADHD, autism, and family history

Medical professionals are highlighting the significant connection between neurodevelopmental disorders, such as Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD), and family history. Neurologist Dr. Matheus Trilico notes that parents often recognize similar behavioral patterns in themselves, such as social interaction difficulties or sensory sensitivities, after their children receive a diagnosis.

Scientific research supports these familial links. A 2024 study published in JAMA Psychiatry involving Swedish population data indicated high heritability for autism. Additionally, ADHD shows a higher occurrence among relatives of diagnosed individuals. The two conditions can also coexist in a single person, a phenomenon sometimes referred to as AuDHD.

Experts also warn that ADHD often goes undiagnosed in adults. Dr. Pablo Agüero Rabes, a neurologist at Fundación Jiménez Díaz University Hospital, explains that many individuals live for decades using compensation strategies to manage difficulties with organization, attention, and impulsivity. These challenges often become more apparent when personal or professional demands increase, affecting work, relationships, and self-esteem.
