Autism is a neurodevelopmental disorder that affects communication, social interaction, and behavior, with a prevalence of one in 54 children in the United States. While there is no cure for autism, there are several therapies that can help children with autism improve their communication, social skills, and behavior. However, autism is often discussed in ways that suggest that autistic people are subjects who cannot actively participate in their own treatment, and this has led to autism treatments that do not benefit autistic people being promoted.
What is Autism?
The complexities of the human brain and its underlying genetic and biological mechanisms are truly fascinating. A recent study by scientists at Aarhus University sheds new light on the genetic factors underlying attention-deficit/hyperactivity disorder (ADHD), a common neurodevelopmental disorder affecting millions of people worldwide. 
By studying over six million genetic variants in nearly 40,000 people with ADHD and almost 187,000 without ADHD, the researchers identified 27 genetic risk variants for the disorder. These risk genes are expressed in the brain and neurons, particularly dopaminergic neurons, which play a role in reward response and the concentration of dopamine in different brain regions.
