Brain Scans Detect Autism in Infants

A new study coordinated by the Montreal Neurological Institute and Hospital has used brain scans to identify brain changes associated with autism.

The researchers took 92 six-month old infants at high risk for autism and used a specialized MRI called diffusion tensor imaging. The babies were followed until the age of 24 months, at which time 30% has an autism diagnosis. The wiring differences were then identified from the original scans.

This news means children may be diagnosed before symptoms emerge. Their parents can then get early intervention, which is key to the best outcome possible.

Could Your Child Have Autism?

Although most children with autism are not identified until they are at least three years of age, there are some warning signs parents may observe earlier.

Dr. Rebecca Landa is the director of the Center for Autism and Related Disorders at the Kennedy Krieger Institute in Baltimore, Maryland. She has suggested parents of children six months of age and older look for the following ten signs during playtime:

1. The child smiles rarely when approached by familiar people.

2. The child does not imitate the sounds and movements of others (e.g. smiling and laughing), or this is rare.

3. Babbling is infrequent or delayed.

4. No response to his or her name from 6-12 months old.

5. No gesturing to communicate by 10 months of age.

6. Lack of eye contact.

7. Does not seek attention on a regular basis.

8. Stiffens up, has uncommon postures, or displays repetitive movements such as hand flapping.

9. Does not reach out to be picked up.

10. Motor delays such as in rolling over, pushing up, or crawling.
