About 11 percent of American children have been diagnosed with ADHD

ADHD is a medical condition characterized by differences in brain development and activity that can cause children to be inattentive, overactive, and impulsive. For example, a child may not listen when spoken to, have difficulty organizing tasks and activities, fidget and squirm while sitting, and talk excessively. While most children struggle with these problems occasionally, the struggle is more difficult and frequent for people with ADHD.

The condition usually begins in childhood but can extend into adolescence and adulthood, with symptoms often changing as the child ages. The researchers found that ADHD is more common in boys than in girls (14.5 versus 8 percent) and that young people aged 12 and older are more likely to be diagnosed with ADHD than young people under 12.

Although a single cause has not been identified for all cases of ADHD, medical experts often point to genetics, noting that children with ADHD often have a parent or family member with the condition. No cure has been found for ADHD, but treatment – ​​which may include medication, therapy (family, psychological, or behavioral), parental coaching, and classroom accommodations for the child – can reduce symptoms and improve the child’s ability to function.
