Abstract: 

Babies born to women with gestational diabetes tend to be large and go through spells of low blood sugar within their first few days of life. They may also be at an increased risk for autism, reports a study published in the Journal of Autism and Developmental Disorders. The study also found that the risk extends to children born to women who had diabetes prior to pregnancy.

Abstract: 

About one-third of people with autism suffer from epilepsy. This overlap suggests that the two disorders may have a common origin — a theory borne out by examples of shared genetics. Mutations in GABRB3, a brain receptor linked to autism, are prevalent in severe childhood epilepsy, according to a study published in Nature. The study also found that many of the spontaneous mutations found in children with epilepsy overlap with those linked to autism and fragile X syndrome.

AUTISM SCIENCE FOUNDATION MARKS 5TH ANNIVERSARY
with a DAY OF LEARNING & EVENING OF CELEBRATION

Day of Learning will feature the Autism Community’s First
TED-Style Scientific Conference

 

(October 21, 2013—New York, NY)  Today the Autism Science Foundation announced plans to celebrate the organization’s fifth anniversary with a full day of events at the Yale Club of New York City on April 10, 2014.

On the afternoon of April 10, ASF will host a festive luncheon, followed by the autism community’s first TED-style conference, featuring talks from NIMH Director Dr. Thomas Insel, Dr. David Amaral, Dr. Joseph Buxbaum, Dr. David Mandell, Dr. Paul Offit, Dr. Matt State, and other prominent scientists, as well as individuals with autism, including Paul Morris, an adult on the autism spectrum. These TED-style talks will be thoughtful, 15-minute distillations of critical issues in autism.  “This event, geared toward all stakeholders, will be our gift back to the autism community,” said Alison Singer, president of the Autism Science Foundation. “Our speakers will focus on the real issues facing families, such as gender differences in diagnosis and treatment, the value of genetics testing, the effectiveness of school-based interventions, and the challenges of finding meaningful employment.”  

The highlight of ASF’s anniversary celebration will be its Fifth Anniversary Gala in the evening of April 10, during which the foundation will honor two leaders in autism science: Dr. Gerald Fischbach, Chief Science Officer of the Simons Foundation, and Dr. Paul Offit, Chief of Infectious Diseases at Children’s Hospital of Philadelphia and author of Autism’s False Prophets.  Dr. Richard Besser, Chief Medical Correspondent for ABC News, will serve as emcee for the evening, which will feature a cocktail reception and dinner, as well as a silent auction and entertainment by teens and adults with autism, including singer Izzie Piwnicki and pianist Josh Frelich.

Proceeds from the day’s events will benefit ASF’s pre- and postdoctoral fellowship programs, which support early career research conducted by the nation’s most promising young autism scientists. For more information about the event, click here

Autism Rates Rise in US, but Level Off in UK

Date Published: 
October 16, 2013
Abstract: 

Autism rates in the United Kingdom appear to have leveled off between the years 2000 and 2010 after a five-fold rate increase in the 1990s. The report, published in the journal BMJ Open, does not have any conclusive answers as to why there was such a dramatic increase in autism diagnosis in the 1990s, but it does state that any link between autism and vaccines has been ruled out. This BMJ Open report is being compared to a report released by the CDC last year that found rates of autism diagnosis in the United States increased 78 percent between 2004 and 2008.

ASF Grantee Publishes Paper in Nature that Brings Insight to Study of Phelan-McDermid Syndrome and Autism

Abstract: 

A new study brings important insights about the cellular and molecular mechanisms involved in the loss and gain of synaptic function in human neurons from patients with Phelan-McDermid syndrome and autism. It also provides encouragement that neurons derived from induced pluripotent stem cells of patients will be useful in understanding and developing treatments for neurodevelopmental and psychiatric disorders.

By Dr. Oleksandr Shcheglovitov
 
22q13.3 deletion syndrome (also known as Phelan-McDermid syndrome) is a genetic neurodevelopmental disorder characterized by global developmental delay, severely impaired speech, intellectual disability, and autism. The syndrome is caused by the heterozygous microdeletions in the terminal region of chromosome 22. Although, a candidate gene responsible for the neurological abnormalities in patients has been suggested (SHANK3, which encodes a scaffolding protein of excitatory synapses), cellular and molecular defects associated with this syndrome were unknown. In the study published in Nature today, researchers from Stanford University reported that human neurons derived from induced pluripotent stem cells of patients with Phelan-McDermid syndrome and autism have deficits in excitatory synaptic transmission due to reduced number of excitatory synapses. The authors demonstrated that SHANK3 is primarily responsible for these deficits, as neurons from patients had reduced SHANK3 expression and increasing the levels of SHANK3 expression rescued synaptic deficits in patient cells.
 
The authors also tested several drugs for their ability to increase the number of excitatory synapses in neurons derived from patients and found that prolonged treatment with Insulin Growth Factor 1 (IGF1) completely restores excitatory synaptic transmission in patient cells. Interestingly, IGF1 produced its action by increasing the number of different type of excitatory synapses that express scaffolding protein PSD95 and lack SHANK3 expression.
 
In summary, this study brings important insights about the cellular and molecular mechanisms involved in the loss and gain of synaptic function in human neurons from patients with Phelan-McDermid syndrome and autism. It also provides encouragement that neurons derived from induced pluripotent stem cells of patients will be useful in understanding and developing treatments for neurodevelopmental and psychiatric disorders.

Abstract: 

Researchers have optimized the production from stem cells of large numbers of a subtype of neurons involved in cognitive function. These neurons express the chemical messenger glutamate and are implicated in cognitive disorders such as autism. This technique, published in Translational Psychiatry, could generate enough neurons for large-scale screening of drugs.

New Behavioral Test Uncovers Autism Mouse's Stubbornness

Abstract: 

Researchers have developed a new test that reveals complex repetitive behaviors in BTBR mice, a mouse strain with features resembling those of autism, according to a study published in the Journal of Neuroscience Methods. Repetitive behavior is common in autism, and usually comes in two forms: repetitive actions, such as hand flapping or rocking, and higher-order symptoms, such as an insistence on sameness, or restricted interests. This second form is difficult to produce in mice, but these researchers believe they have been able to do it.

Abstract: 

New research from the CDC and published in the journal Developmental Medicine & Child Neurology found significantly high rates of autism among children diagnosed with cerebral palsy. Of the 147,000 children studied, seven percent of the children with cerebral palsy were also diagnosed with autism, compared to a little greater than one percent of kids who have autism in the general population.

Deleted Genes Offer Autism Clues

Date Published:

Abstract: 

Research published in the American Journal of Human Genetics found that people with ASDs often have just one copy of certain genes, when typically-developing people have two. This "mis-wiring" could alter the activity of nerve cells in the brain. The study found that the most commonly missing genes were linked to autophagy - a kind of waste-disposal and renewal process for cells. This study was led by Dr. Joseph Buxbaum, who is on ASF's Scientific Advisory Board.

Abstract: 

Some children with autism show unique patterns of brain activation while solving math problems, particularly in a brain region normally used for face processing, suggests a study in Biological Psychiatry. They also seem to use more sophisticated mental strategies to solve these problems than do their typically developing peers, the researchers found.
