Dual Diagnosis - today possible and meaningful
In the past, Attention-Deficit / Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) were not diagnosed at the same time.
Today we know:
- Both are distinct clinical conditions
- They can co-occur
- A combined diagnosis allows for more targeted and individualized support
Prevalence
- 20–50% of individuals with ADHD also meet criteria for ASD
- 30–80% of individuals with ASD also meet criteria for ADHD
- ADHD only: approx. 50–80%
- ASD only: approx. 20–70%
Heritability
There is no single “autism gene” or “ADHD gene”—both conditions are influenced by many genes.
ADHD is highly heritable > approx. 70–80% of the variation is explained by genetic factors
This means: genetics play a major role.
Autism is also strongly genetically influenced > approx. 70–90% of the variation is explained by genetic factors
This means: autism often runs in families, although environmental factors also play a contributing—though smaller—role.
What does this mean for parents?
If your child receives a diagnosis, the likelihood increases that you may recognize similar patterns or traits in yourself.
This is meant to be relieving—not an indication that you did something wrong, “raised your child incorrectly,” or are to blame.
Self-assessment
A personal diagnostic evaluation can help to:
- Better understand your child’s behaviour
- Identify your own strengths and challenges
- Enable more targeted support for the entire family
