A study published today in medical journal The Lancet proves that ADHD is a genetic disorder.
Anita Thapar, professor at Cardiff University, says, “Too often, people dismiss ADHD as being down to bad parenting or poor diet. As a clinician, it was clear to me that this was unlikely to be the case. Now we can say with confidence that ADHD is a genetic disease and that the brains of children with this condition develop differently to those of other children.”
Dr. Nigel Williams, also of Cardiff, says, “Children with ADHD have a significantly higher rate of missing or duplicated DNA segments compared to other children and we have seen a clear genetic link between these segments and other brain disorders.”
The research also shows that there is “some overlap between ADHD and autism in terms of symptoms and learning difficulties.” The most significant of which was found on chromosome 16 “which has been previously implicated in schizophrenia and other major psychiatric disorders.”
