ADHD, autism, learning disorders: what are we actually talking about?

The main profiles

ADHD: difficulties with attention, impulse control and activity level, driven mainly by executive functions — starting, sustaining, organising, perceiving time.

Autism: differences in social communication and interaction, restricted or intense interests, repetitive behaviours and sensory particularities.

Specific learning disorders (dyslexia, dysgraphia, dyscalculia, developmental language disorder) and developmental coordination disorder: a targeted skill develops atypically while overall ability is unaffected.

Intellectual disability: a broader limitation of intellectual functioning and adaptive skills, with wide variation in support needs.

Why they overlap so often

Co-occurrence is the rule rather than the exception: many autistic people also meet criteria for ADHD, and learning disorders frequently appear alongside both. They share developmental mechanisms, so a single label rarely describes a whole person.

Practical consequence: assessing one condition without looking for the others usually leads to partial support.

What matters more than the label

A diagnosis names a profile; it does not describe a person. What changes daily life is the list of concrete needs — noise, written instructions, visible time, predictability — and those can be addressed before, during and regardless of any assessment.

Frequently asked questions

Are neurodevelopmental conditions caused by parenting or screens?

No. They are developmental differences with a strong genetic component. Environment influences how difficulties show up, not whether the condition exists.

Can several conditions be diagnosed at once?

Yes, and it is very common. Diagnostic manuals have allowed combined ADHD and autism diagnoses since 2013.
