causes of attention deficit disorder

causes of attention deficit disorder Attention deficit hyperactivity disorder (ADHD) is developmentally inappropriate behavior in school-age children that results in the inability of the child to focus on the task at hand. More boys than girls are diagnosed with ADHD.
Some researchers believe a child can develop ADHD as early as 4 years of age.

The underlying cause of ADHD is not known; however, the neurotransmitters
dopamine and norepinephrine have been associated with hyperactivity deficits
and serotonin with impulsivity. Researchers have found a family link to ADHD
where a close family relation of a child diagnosed with ADHD also had been
diagnosed with ADHD. ADHD also correlates with a child being exposed to
complications at birth and low birth weight, lead poisoning, child abuse, drug use by the child’s mother when pregnant with the child, and frequent stressful
situations. Some children diagnosed with ADHD are also diagnosed with anxiety
disorder or depression.

Treatment helps children manage the disorder. Some children outgrow symptoms
of ADHD, whereas others continue to express symptoms as adults.
