Dr. Nigg’s research focuses on the underlying mechanisms and causes in attention deficit hyperactivity disorder (ADHD) across the lifespan. The primary focus is on cognitive and neuropsychological mechanisms. However, studies of genetics, family dynamics, personality and temperament, environmental toxins, and neuroimaging of ADHD are also ongoing.
