New Research Suggests the Eyes Can Reveal ADHD or Autism

Diagnosing autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD) can be difficult, particularly in kids with high functioning autism or ADHD. A new study out of Australia used an electroretinogram to look at the electrical activity of the retinas in the eyes to detect differences in people with autism or ADHD. The idea is that children with ADHD have higher levels of energy in the retina in response to light. Children with autism have lower levels of energy in the retina. "This kind of test would help me differentiate them," said Dilip Karnik, pediatric neurologist at Pediatrix® Child Neurology Consultants of Austin. While he finds the research interesting, Dr. Karnik said more data are needed. "It's a good start. If a lot of other people would do it and come to a better conclusion, then it will be a good diagnostic tool."
