The term autism is often used to describe a condition that causes individuals to have difficulties communicating with others.
But it’s not an easy diagnosis to make and some people who have it don’t have it.
Autism spectrum disorder (ASD) can affect people of all ages, from those with mild symptoms to those with more severe symptoms.
The condition affects about 3.6 million people in the US and affects around 1 in every 300 children, according to the National Institutes of Health.
People who have autism may have difficulties in social interaction and other basic needs, including communication and learning.
They also may have trouble with communication and interaction with other people, according the American Academy of Autism Speaks.
People with ASD have some of the same problems as those with ADHD, but can also have difficulties with language, social interaction, repetitive behaviors, repetitive speech, and repetitive motor skills, according with the ASPCA.
Some people with ASD are more likely to have trouble controlling emotions, as well.
This is often because of the brain’s “fight or flight” response, which helps people fight against emotions they don’t like, said Dr. Jennifer R. Dufour, a neuropsychologist at the University of Florida in Gainesville.
Dr. Duscher added that some people with autism also have a greater tendency to have a lack of social skills, such as social withdrawal, and a harder time maintaining social relationships.
She said the social disconnect is also more common among people who are older than 40.
There are a few ways to look at autism and to figure out if you or someone you know has it, said Mark Gorman, a psychiatrist at Johns Hopkins Hospital in Baltimore, Maryland.
You can look at their behavior and how they act around you, which could indicate ASD, said Gorman.
You can look for symptoms that they have in the way they speak, and how that can be interpreted as being socially or language-impaired.
If they talk too much or are overly anxious or inattentive, it could be autism, he said.
You should also check with your child’s school to make sure they are doing well, said Ravi Kumar, a pediatrician and autism expert at Children’s Hospital of Philadelphia.
If your child seems fine at school, you should ask questions about what’s going on, Kumar said.
People should also discuss how their family can help, he added.
If there’s a family history of autism, you can also seek support from a psychologist, he suggested.
You also can talk with your pediatrician or child’s doctor to see if they can get you a special diagnosis for your child.
If you or a loved one has autism, it’s important to take the right steps to manage the condition, Gorman said.
The National Institutes for Health said it does not endorse the use of autism-related terms, such the term autism spectrum disorder, autism spectrum diagnosis, autism, autism diagnosis, and autism spectrum condition.
It’s not clear why people with the condition feel like autism is a negative thing.
Autism is an umbrella term for different conditions, said Katherine A. Smith, a professor of psychiatry at the Harvard Medical School and the author of the book, “Autism: A New Diagnosis.”
People with autism have different symptoms, and they may be different people with different backgrounds, Smith said.
People with ASD also may experience problems with social communication and communication skills.
Autistic people have more difficulty in communicating with people and with other groups of people, but they also may be more outgoing and social, Smith added.
You also may not always have the skills to manage emotional needs, Smith noted.
To find out if your son or daughter has autism or any other disability, your child or teen should have a parent or guardian who knows your child well, Dr. Daus said.
