ADHD Causes & Treatments

Attention deficit hyperactivity disorder (ADHD) is a common childhood behavioral disorder. ADHD is characterized by inattention, hyperactivity and impulsive behavior. This informative video animation shows possible causes and treatments.

ADHD stands for attention deficit hyperactivity disorder. ADHD used to be known as attention deficit disorder, or ADD. In 1994, it was renamed ADHD. The term ADD is sometimes still used, though, to describe a type of ADHD that doesn't involve hyperactivity.

ADHD is a medical condition that affects how well someone can sit still, focus, and pay attention. People with ADHD have differences in the parts of their brains that control attention and activity. This means that they may have trouble focusing on certain tasks and subjects, or they may seem "wired," act impulsively, and get into trouble.

Symptoms and Signs of ADHD
Although ADHD begins in childhood, sometimes it's not diagnosed until a person is a teen — and occasionally not even until someone reaches adulthood.

Because ADHD is a broad category covering different things — attention, activity, and impulsivity — it can show up in different ways in different people. Some of the signs of ADHD are when someone:

  • has difficulty paying attention or staying focused on a task or activity
  • has problems finishing assignments at school or home and jumps from one activity to another
  • has trouble focusing on instructions and difficulty following through
  • loses or forgets things such as homework
  • is easily distracted, even when doing something fun
  • has problems paying close attention to details or makes careless mistakes
  • has trouble organizing tasks and activities
  • has difficulty waiting one's turn
  • interrupts or intrudes on other people
  • blurts out answers before questions have been completed
  • fidgets with hands or feet or squirms about when seated
  • feels restless
  • talks excessively and has trouble engaging in activities quietly

Of course, it's normal for everyone to zone out in a boring class, jump into a conversation, or leave their homework on the kitchen table once in a while. But people with ADHD have so much trouble staying focused and controlling their behavior that it affects their emotions and how well they do in school or other areas of their lives. In fact, ADHD is often viewed as a learning disorder because it can interfere so much with a person's ability to study and learn.

Sometimes the symptoms of ADHD become less severe as a person grows older. For example, experts believe that the hyperactivity part of the disorder can diminish with age, although the problems with organization and attention often remain. Although some people may "grow out of" their symptoms, more than half of all kids who have ADHD will continue to show signs of the condition as young adults.

What Causes ADHD?
Doctors and researchers still aren't exactly sure why some people have ADHD. Research shows that ADHD is probably genetic and that it may be inherited in some cases. Scientists are also exploring other things that may be associated with ADHD: For example, ADHD may be more prevalent in kids who are born prematurely. It is also more common in guys than it is in girls.

Doctors do know that ADHD is caused by changes in brain chemicals called neurotransmitters (pronounced: nur-oh-trans-mih-terz). These chemicals help send messages between nerve cells in the brain. The neurotransmitter dopamine (pronounced: doe-puh-meen), for example, stimulates the brain's attention centers. So a person with low amounts of this chemical may show symptoms of ADHD.

How Is ADHD Treated?
Because there's no cure for ADHD, doctors treat people by helping them to manage the symptoms most effectively. Because some people have more trouble with the attention side of the disorder and others have more problems with the activity side, doctors tailor their treatment to the person's symptoms. So different people with ADHD may have different treatments.

Doctors usually follow a multimodal (pronounced: mul-tee-moe-dul) approach to ADHD treatment. This means that they use several different treatment methods for one patient, such as medication, family and individual counseling, and changes at school to address particular learning styles.

Certain medicines can help people with ADHD by improving their focus and attention and reducing the impulsiveness and hyperactivity associated with ADHD. People with ADHD used to have to take medicine several times a day, but now there are some that can be taken at home once a day in the morning. Scientists are constantly working to develop new medications to treat ADHD.

You can discuss treatment options with your doctor, but always follow the doctor's instructions about medication dosages. If you have been taking medicine for ADHD since you were a kid, your doctor will probably adjust your medication for changes in your symptoms as you get older.

Family counseling helps treat ADHD because it keeps parents informed and also shows them ways they can work with their kids to help. It also helps to improve communication within the family and to solve problems that come up between teens and their parents at home. Individual counseling helps teens with ADHD to better understand their behavior and to learn coping skills. Sometimes lots of teens with ADHD work together in group therapy, which helps them work on coping skills and getting along better with others, if that's been a problem.

Schools are also involved in helping students with ADHD — most will develop a plan that's right for each teen and make changes that allow learning in ways that work best for them.

People with ADHD may also have other problems, such as depression, anxiety, or learning disabilities like dyslexia, that require treatment. They also may be at greater risk for smoking and using drugs, especially if the ADHD is not appropriately treated. That's why proper diagnosis and treatment are critical.

If You or Someone You Know Has ADHD
Most teens with ADHD are diagnosed as kids, but some people aren't diagnosed until they're in their teens or even older. It's normal to feel overwhelmed, scared, or even angry if you've been diagnosed with ADHD. That's one thing counseling can help with. Talking about those feelings and dealing with them often makes the process much easier.

If you have ADHD, you may not be aware that you're behaving in a way that's different from others; you're just doing what comes naturally. This can sometimes cause problems with people who don't understand or know about your condition. For example, you might speak your mind to someone only to get the feeling that you've shocked or offended that person. You may not understand why people get mad at you.

Learning all you can about your condition can be a huge help. The more you understand, the more involved you can be in your own treatment. Here are some of the things you might try to help with school and relationships:
