Bethan Burnside recently started her PhD in Biomedical Sciences with Professor Frank Kooy in the Cognitive Genetics Lab at the UAntwerp Center of Medical Genetics. She aims to explore the epigenetics of ADHD in adult women. Until recently, attention deficit hyperactivity disorder (ADHD) was thought of as a neurodevelopmental condition that occurs in young boys. In fact, even Bethan believed this to be the case – until she was diagnosed with ADHD herself at the age of 25! Unfortunately, due to these misconceptions, ADHD in girls and women is often diagnosed too late or misdiagnosed as something else.
