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.
Podcast: Here’s to understanding why people with autism have anxiety in adolescence
On this week’s podcast, highlights of a new study led by Dr. Amy Kalkbrenner of the University of Wisconsin Milwaukee published in Environmental Health Perspectives—certain air pollutants from cars and coal burning plants were associated with autism risk and severity. This scientific evidence supports policies which keep U.S. Environmental Protection Agency infrastructure intact to monitor air quality.
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.
The Moyer family was recently featured in the Sag Harbor Express for their participation in the Autism Sisters Project. The advances made through this research would not be possible without the contribution of families like theirs. Read about them here.
A new study by the CDC, including Dr. Matthew Maenner, ASF Grantee ’10, found that 95% of children with autism have at least one psychiatric or medical comorbidity, which may have a role in age of first evaluation—the more comorbid conditions, the earlier the first evaluation for ASD. Read the study here.
On this week’s podcast, Dr. Alycia Halladay overviews three recent studies, including one done in collaboration with the Autism Treatment Network, looking at how sleep problems impact the behavior and functioning of individuals with autism across the spectrum.
SETD5 is a master regulator of gene activity that controls the activity of potentially thousands of other downstream genes in the same cell. Researchers, supported in part by ASF, found that this gene is associated with a subtype of autism that is seen mostly in males and includes intellectual disability and facial dysmorphology. This is further support of different genes and gene combinations contributing to different features of autism, rather than the entire spectrum. The UC San Diego investigators, including Dr. Isabella Rodrigues Fernandes, ASF Grantee ’17, in this study will continue to investigate this gene and how it affects brain development, which may lead to therapeutic interventions for those who carry this mutation. Read the study here.
On this week’s podcast, Dr. Alycia Halladay overviews three new studies looking at commonly used drugs that may help autism not just by improving behavior, but also by how they impact the brain. Plus, a fun study about social media.
On this week’s podcast, a study led by Elizabeth Berg in the lab of Dr. Jill Silverman at UC Davis published in the journal Autism Research demonstrated SHANK3’s role in core social communication deficits in a rat model of autism. Rats exhibit both receptive and expressive communication. SHANK3 mutations are seen in those with Phelan-McDermid Syndrome as well as in 1% of people with autism. This new study opens up new ways to understand autism symptoms in an animal model, and moves autism research using animals forward significantly.
On this week’s podcast, Dr. Katherine Stavropoulos (ASF Grantee ’14) highlights her research with her UC Riverside colleague Dr. Leslie Carver on brain patterns that may explain the social communication deficits present in ASD. Plus, recent research from the Study to Explore Early Development led by Dr. Eric Rubenstein of UNC presented findings that demonstrated increased odds of autism symptoms for children of at least one parent with broader autism phenotype.
This week’s ASF podcast explores differences in sexuality and sexual relationships between those with autism and without, and also differences between males and females with autism. While this is not a new topic, the number of publications and research has exploded this year. Learn more here.
