ADHD and autism 


Many people with ADHD also have autism. This combined condition is often referred to as AuDHD.

When the two neurodevelopmental conditions work well together you can get the best of both worlds – quick thinking creativity with deep focus and attention to detail.

However, when the conditions clash, it can feel like your brain is fighting itself.

Autism New Zealand has shared a series of resources written by autistic and AuDHD authors with us.

These documents explore the differences and similarities between autism and ADHD and how they present when combined, as well as providing tips and strategies to make the most of your unique brain.

We have made them available in both PDF and Word format.

Autism and ADHD

Autistic people often have differences in the way their senses process. They are often quite sensitive to noises, smells, textures, tastes and visual clutter or lights.

ADHDers have very busy brains. They may seek sensory input such as music, tastes, textures, and fidget items or they may find that sensory input distracts them.

AuDHDers can become distressed or overstimulated by the clash between the needs each condition has.

This resource provides tips for coping sensory overwhelm, emotional dysregulation and disappearing time, among other symtoms.
