Aggression. Forgetfulness. Boredom. These are among the signs of attention deficit hyperactivity disorder — which affects millions of Americans. ADHD Awareness Month, sponsored by the Attention Deficit Disorder Association and observed each October, highlights the latest research and clinical studies with the goal of bringing more effective treatments. Its guiding principle is that life can be better for those with ADHD and for those who love or work with someone with ADHD.
