What is ADHD?

ADHD is an acronym for attention deficit hyperactivity disorder. This is a set of chronic conditions marked by an inability to pay attention, hyperactivity and impulsive acts. It begins in childhood and can affect all areas of a child's life. In recent years, the National Institute of Mental Health has declared definitively that ADHD is a mental health condition.

How common is ADHD?

Between 3 and 5 percent of school-aged children - or about 2 million children in the United States - have ADHD, according to the National Institute of Mental Health. Boys outnumber girls by at least a three to one ratio, according to National Mental Health Association. About 80 percent of children who take medications for their ADHD continue to need the drugs during their teen years, according to the National Institute of Mental Health.

Do head injuries or poor parenting cause ADHD?

No. Earlier theories suggested that minor head injuries or brain damage caused by infections or birthing complications might be responsible for ADHD. However, experts have not found evidence to support this hypothesis. Theories that too much or too little sugar may cause ADHD also appear to be unfounded.

Poor parenting skills do not cause a child's ADHD. Nonetheless, problems in the home or difficulties in school or community environments can exacerbate ADHD.
