From the Mayo Clinic
“Attention-deficit/hyperactivity disorder (ADHD) is a chronic condition that affects millions of children and often continues into adulthood. ADHD includes a combination of persistent problems such as difficulty sustaining attention, hyperactivity, and impulsive behavior.
Children with ADHD may also struggle with low self-esteem, troubled relationships, and poor performance in school. Although symptoms sometimes lessen with age, some people never completely outgrow their ADHD symptoms; however, they can learn strategies to be successful.”
