Autism spectrum
disorder (ASD)
What is autism
spectrum disorder?
Autism spectrum disorder (ASD) is a developmental disability
caused by differences in the brain. Scientists do not know yet exactly what
causes these differences for most people with ASD. However, some people with
ASD have a known difference, such as a genetic condition. There are multiple
causes of ASD, although most are not yet known.
There is usually nothing about how people with ASD look that
sets them apart from other people, but they 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
gifted to severely challenge.
Some people with ASD need a lot of help in their daily
lives; others need less.
A diagnosis of ASD now includes several conditions that used
to be diagnosed separately: autistic disorder, pervasive developmental disorder
not otherwise specified (PDD-NOS), and Asperger syndrome. These conditions are
now all called autism spectrum disorder.
What are some of the
signs of ASD?
People with ASD often have problems with social, emotional,
and communication skills. They might repeat certain behaviours and might not
want change in their daily activities. Many people with ASD also have different
ways of learning, paying attention, or reacting to things. Signs of ASD begin
during early childhood and last throughout a person’s life.
Children or adults with ASD might:
1. Not point at objects to show interest (for example, not
point at an airplane flying over)
2. Not look at objects when another person points at them
3. Have trouble relating to others or not have an interest
in other people at all
4. Avoid eye contact and want to be alone
5. Have trouble understanding other people’s feelings or
talking about their own feelings
6. Prefer not to be held or cuddled, or might cuddle only
when they want to
7. Appear to be unaware when people talk to them,but respond
to other sounds
8. Be very interested in people, but not know how to talk,
play, or relate to them
9. Repeat or echo words or phrases said to them, or repeat
words or phrases in place of normal language
10. Have trouble expressing their needs using typical words
or motions
11. Not play “pretend” games (for example, not pretend to
“feed” a doll)
12. Repeat actions over and over again
13. Have trouble adapting when a routine changes
14. Have unusual reactions to the way things smell, taste,
look, feel, or sound
15. Lose skills they once had learned (for example, stop
saying words they were using)
What can I do if I
think my child has ASD?
Talk with your child’s doctor or nurse. If you or your
doctor thinks there could be a problem, ask for a referral to see a
developmental pediatrician or other specialist.
Don’t wait. Acting
early can make a real difference!
