Autism Spectrum Disorder(ASD)(孤独症）is a disability that can cause serious social,communication and behavioral problems.There is often nothing about how people with ASD look that makes them different from other people,but people with ASD may communicate,interact,behave,and learn in ways that are different from most other people.The learning,thinking,and problem-solving abilities of people with ASD can range from pretty good to extremely bad.Some people with ASD need a lot of help in their daily lives;others need less.

People with ASD often have problems with social,emotional,and communication skills.They might repeat certain behaviors and might not want change in their daily activities.Many people with ASD may also have difficulties learning,paying attention,or reacting to things.Signs of ASD begin during early childhood and probably last throughout a person's life.

Diagnosing(诊断）ASD can be difficult since there is no medical test,like a blood test,to assess the disorders.Doctors look at the child's behavior and development to make a judgement.ASD can sometimes be diagnosed at 18 months or younger.By age 2,an experienced doctor can be considered very reliable in diagnosing ASD.However,many children may not see a doctor until much older.

There is currently no cure for ASD.However,research shows that early treatment services can improve a child's development.Early treatment services help children from birth to 3 years old(36 months)learn important skills.Therefore,it is important to talk to your child's doctor as soon as possible if you think your child has ASD or other developmental problems.

We do not know all of the causes of ASD.However,most scientists agree that genes are one of the highest risk factors that can make a person more likely to develop ASD.

If you think your child might have ASD or you think there could be a problem with the way your child plays,learns,speaks,or acts,contact your child's doctor,and share your concerns.If you're not sure who to contact,call the Early Childhood Technical Assistance Center(ECTA)at 919-962-2001.Or visit the ECTA website:https://ectacenter.org.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.

Previous studies have linked high exposure to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can lead to heart attack or stroke(中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants(污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
