This week, Dr. Mark Shen from The University of North Carolina at Chapel Hill explains new findings looking at the fluid around the brain. It’s now seen in families even without a family history of ASD, the finding has now been seen in different independent studies, including those at the UC Davis MIND Institute in California, it might be a diagnostic biomarker of ASD, and it also might help explain sleep problems. Hear more on this week’s podcast.
On this week’s ASF podcast: By looking directly at the brains of people with autism, researchers at UC Davis MIND Institute, led by Dr. Thomas Avino and Dr. Cyndi Schumann, show a disruption of neuron number in the amygdala in autism. The amygdala is important because it is linked to emotion, fear and anxiety in people with autism. The shift in too many vs. too few neurons that occurs in adolescence may help explain anxiety in people with ASD. Read the full open-access article here.
Researchers at Autism BrainNet node UC Davis MIND Institute found that while typically-developing children gain more neurons in a region of the brain that governs social and emotional behavior, the amygdala, as they become adults, people with ASD do not. The open access research published in PNAS studied 52 postmortem human brains, both neurotypical and ASD, ranging from 2 to 48 years of age. There were more neurons in young children with ASD, but as they got older, those numbers went down. The press release on this article can be read here.
