Researchers from the national psychiatric project iPSYCH have found that autism and ADHD share changes in the same genes. The new knowledge relates directly to the biological causes of the two child psychiatric disorders.
In Denmark, approximately one per cent of schoolchildren have autism and two to three per cent are diagnosed with ADHD. Autism and ADHD are different developmental disorders, but they can have certain common symptoms. For example, children with autism can demonstrate violent or aggressive behaviour, be impulsive, and have problems in school and with social relations — and these same symptoms can be shared by children with ADHD.
