Am I at Risk?


Between 1990 and 2004, the number of diagnosed cases of ADHD increased from 950,000 to 4.5 million among children aged 3 to 17. ADHD is seen to be more often diagnosed in boys, and, though it is primarily diagnosed in children, the condition can be diagnosed in adults as well. Theories exist that ADHD is caused by second-hand smoke, coloring in food, a particular diet and genetics, among countless others.
