ADHD gene doesn't predict response to drugs

Canadian researchers report that a gene variant that seems to affect the severity of attention-deficit hyperactivity disorder did not help them predict which patients are likely to respond to a class of drugs widely used to treat the disorder. The research was published Wednesday in Neuropsychopharmacology and conducted by McGill's Ridha Joober, associate professor psychiatry & human genetics and his team from the Douglas Mental Health University Institute.
