Deletions Within Certain Chromosome Can Lead to Autism Development

Follow-up studies will be able to predict long-term outcomes

Participants in the 22q deletions group, who were at risk for schizophrenia, revealed thicker gray matter and less brain surface area. On the contrary, participants in the 22q duplications group, who were at risk for autism, revealed thinner gray matter and larger brain surface area. “The next question is how does brain anatomy -- and brain function -- relate to psychiatric outcomes? These findings provide a snapshot. We are now conducting follow-up studies to track predictors of outcome over time. Those are the puzzle pieces that are next on our list to disentangle,” said Bearden.
