5 September 2014 | 7:00 am

Recent research has revealed that many children and adults with autism experience gastrointestinal symptoms and that such symptoms can impact the absorption and availability of medications.

Researchers find possible root of autism in early cerebellum injury

4 September 2014 | 8:00 am

A brain region largely known for coordinating motor control has a largely overlooked role in childhood development that could reveal information crucial to understanding the onset of autism...

Pilot study of socially-assistive robots that help children with autism to learn imitative behavior

2 September 2014 | 7:00 am

A team of researchers from the USC Viterbi School of Engineering share results from a pilot study on the effects of using humanoid robots to help children with autism practice imitation behavior in...

Changes in ADNP gene may be among the most common causes of autism

2 September 2014 | 7:00 am

A new study from Bradley Hospital has identified a genetic change in a recently identified autism-associated gene, which may provide further insight into the causes of autism.

Previously reported autism risk appears to be attributable to mother's prenatal antidepression, not medication

28 August 2014 | 8:00 am

Previous studies that have suggested an increased risk of autism among children of women who took antidepressants during pregnancy may actually reflect the known increased risk associated with severe...

In stress hormone regulation, maturing brain flips function of amygdala

23 August 2014 | 7:00 am

In contrast to evidence that the amygdala stimulates stress responses in adults, researchers at Yerkes National Primate Research Center, Emory University have found that the amygdala has an...

Children with autism 'have too many synapses in their brain'

22 August 2014 | 3:00 pm

Researchers from Columbia University Medical Center in New York, NY, find that children with autism have excess synapses in their brain, which impacts brain function.

Algorithm developed to uncover genomic insertions and deletions involved in autism, OCD

19 August 2014 | 8:00 am

With three billion letters in the human genome, it seems hard to believe that adding a DNA base here or removing a DNA base there could have much of an effect on our health.

Sexual victimization a greater risk for adults with autism

19 August 2014 | 7:00 am

Adults with autism are at a higher risk of sexual victimization than adults without, due to lack of sex education, but with improved interventions that focus on sexual knowledge and skill building...

How information flow in the brain is centrally regulated for sleep and wakefulness

19 August 2014 | 7:00 am

Ever wonder why it's hard to focus after a bad night's sleep? Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal...

In children with autism, blood-oxytocin levels found to be in normal range

6 August 2014 | 8:00 am
