Attention deficit/hyperactivity disorder (ADHD)

Research Focus

My research focuses on attention-deficit/hyperactivity disorder (ADHD). Today, effective medication treatments relieve many symptoms of ADHD. Yet medication alone does not resolve the social, academic and emotional challenges of children, adolescents, and adults with ADHD. I have been involved in a joint study with the Université de Montréal to help children with ADHD who fall between the cracks in the transition from elementary to high school. The program involves parental training, and organizational/study-skills training for the children. A cognitive-behaviour therapy program that focuses on these areas for adolescents and adults with ADHD has also been developed. In terms of functional outcomes, two large-scale studies in which I participated clearly showed the benefit of combining medication with psychosocial treatment for children with ADHD, as opposed to either treatment alone. However, these benefits do not last without ongoing treatment and follow-up. Another of my current studies aims to determine the optimal follow-up needed to maintain treatment gains.
