How do they work? Are they safe?- Why do those with ADHD have additional emotional, cognitive, and learning disorders more often than most others?- What commonly-held assumptions about ADHD have now been proven wrong by scientific research?Psychiatrists, psychologists, social workers, and other medical and mental health professionals, as well as those affected by ADHD and their families, will find this to be am insightful and invaluable resource"--
