ADHD, or attention deficit hyperactivity disorder, is a common neurobehavioral developmental disorder. The hallmarks of ADHD are problems with inattention, hyperactivity, and impulsivity. ADHD usually occurs in childhood and can continue into adulthood. It is estimated that three to five percent of the children in the U.S have ADHD, according to the National Institutes of Health.
The predominant symptoms or behaviors of ADHD are inattention, hyperactivity, and impulsivity. These behaviors result in further symptoms, including difficulties with concentration, controlling behavior, and remaining focused on a task or activity. People with ADHD may also experience hyperactivity or over-activity. For more information about symptoms, refer to symptoms of ADHD.
ADHD does not directly cause complications, but people with the condition are more likely to have or develop such conditions as Tourette syndrome, anxiety disorder, depression, conduct disorder, and learning disabilities.
The cause or causes of ADHD are not yet known, although researchers believe that genes may be one factor in its development. It is most likely that the disorder is the result of a combination of elements, including environmental factors, exposure to toxins, traumatic head injury, nutrition, and/or social influences.
A common misnomer about the cause of ADHD is that children with the disorder are "spoiled" or that they consume too much sugar and caffeine. Although caffeine may have some impact on energy levels, ADHD is a true medical disorder and is not cause purely by "bad parenting" or too much candy. Current studies have not linked the use of sugar to a difference in behavior.
There is no single test for ADHD, and a diagnosis of the condition is based partly on symptoms. Only a full evaluation by a licensed health care professional can truly diagnose or rule out ADHD. It is generally accepted that person must exhibit symptoms to an extent greater than the average person of the same age for six months or more.
It is important that a person who is exhibiting symptoms of ADHD be evaluated for other medical conditions that might be affecting their behavior. These include petit mal seizures, diabetes, learning disabilities, depression, anxiety, and conditions that can affect hearing or vision, such as ear infections or a need for glasses.
Although there is no cure, ADHD is treatable and can be successfully controlled to effectively reduce symptoms and allow a person with the condition to live a normal, productive life. This can be achieved by developing an individualized treatment plan that may include the use of a combination of medication and psychotherapy.
This is no way to directly prevent ADHD, but there are ways to help ensure that a person is as healthy as possible and best able to live effectively with ADHD. These include not smoking, avoiding toxins, and keeping a daily routine. For more information on treatment, refer to treatment of ADHD. ...more »
