Yes, ADHD and stimming in autism are closely connected, and the co-occurrence of neurodivergence in both conditions can influence how, when, and why stimming happens. Many autistic individuals also have ADHD, and this combination often results in increased or more varied stimming behaviours.

When someone experiences both ADHD and stimming in autism, they may engage in more physical or frequent stims, driven by sensory needs, emotional regulation, or a need to release excess energy.

How ADHD Influences Stimming in Autism

Understanding this overlap helps explain the diversity in stimming behaviours:

Increased movement

People with ADHD tend to have high energy levels and restlessness. This hyperactivity and stimming connection can lead to more visible, frequent, or intense repetitive behaviours such as tapping, bouncing, or fidgeting.

Sensory and focus challenges

Both autism and ADHD can affect sensory processing and attention. Stimming may serve a dual purpose, calming the sensory system while also improving focus in noisy or overwhelming environments.

Shared traits, unique patterns

The ADHD-autism overlap means stimming isn’t just about autism alone. The blend of traits can produce complex behaviours that require personalised support and understanding.

Recognising how ADHD and stimming in autism interact allows for more tailored approaches in education, therapy, and daily life, especially for those navigating multiple neurodivergent experiences.
