Are ADHD and Autism Spectrum Disorder Often Diagnosed Together? 

Yes, ADHD and autism are often diagnosed together, as they can share overlapping symptoms, particularly in areas such as social interaction, communication and behaviour. Children with both conditions may experience challenges in managing their attention, regulating their impulses and processing sensory information. This dual diagnosis is becoming more recognised as professionals gain a better understanding of how these neurodevelopmental disorders can co-occur. 

Having both ADHD and autism can make it more difficult for a child to function in everyday life, especially in school or social settings. While ADHD is typically characterised by hyperactivity, impulsivity and inattention, autism often involves challenges in social communication, rigid behaviours and sensory sensitivities. The combination of these traits can lead to more complex needs and greater support requirements. 

Common Symptoms 

Difficulty with focus 

Children with both ADHD and autism may struggle to maintain attention, which can impact their learning and social interactions. 

Social communication challenges 

They may have trouble understanding social cues, making conversations more difficult or awkward. 

Impulsivity and rigidity 

A combination of ADHD and autism may lead to both impulsive actions and a strong need for routine, creating conflicts in various environments. 

Recognising ADHD and autism as neurodevelopmental disorders that can occur together helps guide appropriate interventions, ensuring children receive the tailored support they need to thrive.
