Definition
Attention deficit hyperactivity disorder, or AD/HD, is a disorder in which an individual consistently shows certain behaviors over time. The three categories for these behaviors are inattention, hyperactivity, and impulsivity.
What is going on in the body?
In people who have ADD, the parts of the brain areas that control attention use less glucose than in other individuals. This indicates that the areas are less active. The lower activity level seems to cause inattention. No one knows for sure why these brain areas are less active.
What are the signs and symptoms of the condition?
People with AD/HD may show the following signs of inattention:
- being easily distracted by sights, sounds, and other stimuli
- losing or forgetting tools and materials needed for a job
- making careless mistakes because of poor attention to details
Someone who has AD/HD may also show signs of impulsivity and hyperactivity, such as:
- feeling restless much of the time
- fidgeting or squirming
- having trouble waiting in line
- interrupting while another person is speaking
- moving around when quiet behavior is expected
What are the causes and risks of the condition?
No one knows the exact cause of AD/HD. Most experts believe that the following factors may play a role in causing AD/HD:
What can be done to prevent the condition?
Many times, AD/HD cannot be prevented. The following measures may be helpful:
How is the condition diagnosed?
Diagnosis of AD/HD begins with a medical history and physical exam. The healthcare provider will look for behaviors that are typical of AD/HD. In order to diagnose AD/HD, the provider must determine that the behaviors have certain characteristics:
- They are more frequent or severe than in other people of the same age group.
- They create significant disability in at least two areas such as school, home, work, or social settings.
- They started early in life, before the age of 7.
- They have been constant for at least 6 months.
The healthcare provider may order tests to rule out other disorders. These tests may include:
What are the long-term effects of the condition?
Without effective treatment, AD/HD can cause serious problems at school, home, work, and social settings.
What are the risks to others?
ADHD is not contagious. It poses no risk to others. There may be a genetic component to the disorder.
What are the treatments for the condition?
Treatment for AD/HD usually involves medicine along with one or more other strategies. The most common medicine for AD/HD is a stimulant called methylphenidate. This medicine is available in a number of name-brand products, such as Ritalin, Concerta, or Metadate.
Other medicines used to treat AD/HD include the following:
- amphetamines, such as Adderall, Dexedrine, or Dextrostat
- antidepressants, such as desipramine (i.e., Norpramin) or bupropion (i.e., Wellbutrin)
- medicines normally used to treat high blood pressure, such as clonidine (i.e., Catapres)
Medicines are often used together with other treatment strategies, such as:
What are the side effects of the treatments?
Side effects from medicines can include the following:
A person who is receiving any form of therapy may show an initial increase in negative behavior. This may last until new behaviors become routine.
What happens after treatment for the condition?
Treatment and monitoring of AD/HD can be lifelong for many patients, although for some, the symptoms seem to reduce or go away over time.
How is the condition monitored?
Any new or worsening symptoms should be reported to the healthcare provider.
