What Does Autism Mean?

Autism (say: aw-tih-zum) causes kids to experience the world differently from the way most other kids do. It’s hard for kids with autism to talk with other people and express themselves using words. Kids who have autism usually keep to themselves and many can’t communicate without special help.

They also may react to what’s going on around them in unusual ways. Normal sounds may really bother someone with autism — so much so that the person covers his or her ears. Being touched, even in a gentle way, may feel uncomfortable.

Kids with autism often can’t make connections that other kids make easily. For example, when someone smiles, you know the smiling person is happy or being friendly. But a kid with autism may have trouble connecting that smile with the person’s happy feelings.

A kid who has autism also has trouble linking words to their meanings. Imagine trying to understand what your mom is saying if you didn’t know what her words really mean. It is doubly frustrating then if a kid can’t come up with the right words to express his or her own thoughts.

Autism causes kids to act in unusual ways. They might flap their hands, say certain words over and over, have temper tantrums, or play only with one particular toy. Most kids with autism don’t like changes in routines. They like to stay on a schedule that is always the same. They also may insist that their toys or other objects be arranged a certain way and get upset if these items are moved or disturbed.

If someone has autism, his or her brain has trouble with an important job: making sense of the world. Every day, your brain interprets the sights, sounds, smells, and other sensations that you experience. If your brain couldn’t help you understand these things, you would have trouble functioning, talking, going to school, and doing other everyday stuff. Kids can be mildly affected by autism, so that they only have a little trouble in life, or they can be very affected, so that they need a lot of help.

What Causes Autism?

Autism affects about 1 in every 150 kids, but no one knows what causes it. Some scientists think that some kids might be more likely to get autism because it or similar disorders run in their families. Knowing the exact cause of autism is hard because the human brain is very complicated.
The brain contains over 100 billion nerve cells called neurons (say: nur-ahns). Each neuron may have hundreds or thousands of connections that carry messages to other nerve cells in the brain and body. The connections and the chemical messengers they send (called neurotransmitters) let the neurons that help you see, feel, move, remember, and work together as they should.

For some reason, some of the cells and connections in the brain of a kid with autism — especially those that affect communication, emotions, and senses — don’t develop properly or get damaged. Scientists are still trying to understand how and why this happens.

What Do Doctors Do?

Figuring out if a kid has autism can be difficult. A parent is usually the first to suspect that something is wrong. Maybe the kid is old enough to speak but doesn’t, doesn’t seem interested in people, or behaves in other unusual ways. But autism isn’t the only problem that can cause these kinds of symptoms. For example, kids who have hearing problems might have trouble speaking, too.

Usually, the results of lab tests and other medical tests are normal in kids with autism, but doctors may do them to make sure the kid doesn’t have other problems. These medical tests can include blood and urine tests, a hearing exam, an EEG (a test to measure brain waves), and an MRI (a picture that shows the structure of the brain). Intelligence (IQ) tests also might be done.

Often, specialists work together as a team to figure out what is wrong. The team might include a pediatrician, a pediatric neurologist, a pediatric developmentalist, a child psychiatrist, a child psychologist, speech and language therapists, and others. The team members study how the child plays, learns, communicates, and behaves. The team listens carefully to what parents have noticed, too. Using the information they’ve gathered, doctors can decide whether a child has autism or another problem.
