Signs

Children that have autism often are anti-social, show no emotion, and ignore noises. Lack of verbal communication and facial expression are very common signs of autism. Another sign is reoccurring seizures.

To diagnose autism, the child be physically examined using M-CHAT checklist. The M-CHAT checklist is a list with common autism symptoms that the doctor will check the child for. Some patients may be tested using the FISH genetic testing. The FISH (fluorescent in situ hybridization) test is DNA test that searches form gene abnormalities.

Treatment
