Children with autism tend to engage in certain behaviors differently than those without the disorder, and they do not display some critical development behaviors. According to the American Academy of Child and Adolescent Psychiatry, or the AACAP, autism is usually identified in children at around the age of 3 months, when parents bring them to the doctor to voice concern about possible developmental delays. When asked, parents are usually able to trace the symptoms of autism back to the child's infancy, notes the AACAP.
Step 1
Look for problems with social interaction. According to MayoClinic.com, there are several signs of social interaction problems to look for when recognizing autism. Pay attention to whether or not the child is responding to his name. Make note of whether or not he makes eye contact with you or others. Be aware of whether or not he enjoys cuddling or holding. Determine whether or not he is aware of and understands the feelings others are experiencing. Watch to see if he prefers to play alone and seems to be in his own world. MayoClinic.com notes that if a child displays some of these social problems, he may be experiencing symptoms of autism.
Step 2
Pay attention to strange movements of the child's body. According to the AACAP, children who display body movements such as constant rocking, whirling, teeth-grinding and head-banging may be engaging in behaviors associated with autism.
Step 3
Develop an understanding of the child's language skills. According to MayoClinic.com, it is important to pay attention when the child begins to talk. Children should begin talking no later than the age of 2; also be aware of any other delays in development by 30 months. If a child loses any previously acquired skills, speaks in an abnormal tone or rhythm--such as in a singsong voice or using robotic speech--or can repeat words and phrases exactly as they were said but has no idea how to use them, she may be displaying early signs of autism, reports MayoClinic.com.
Step 4
Get to know the child's routines. Children with autism tend to feel comfortable with routines and can become very upset if even the slightest change is made, notes MayoClinic.com. Watch the child; see if he always goes through the same steps to accomplish something. Pay attention to the child's reaction when normal family routines are adjusted. If he seems to focus on his routines and be calmed by them, he may be experiencing autism.
Tips and Warnings
- If you think your child is displaying any signs of autism, it is important to contact the doctor immediately in order to voice your concerns and the symptoms. Early detection of autism can lead to earlier treatments and a better prognosis for the child.
