Science News About Autism

High levels of maternal inflammation during pregnancy have been linked to effects in children, including reduced brain circuit communications and altered long-distance brain wiring at birth, poorer cognitive function at one year – and to reduced impulse control and working memory at two years.

Young people with autism unknowingly tuned up flagging neural connections by playing a picture puzzle game that was rigged by their own brain activity.

A new study has identified an association between paternally-inherited rare structural variants in noncoding segments of genes and the development of autism spectrum disorder (ASD). The study adds to a growing body of research describing genetic contributors to ASD.

Depression, schizophrenia and autism spectrum disorder share some of the same patterns of suspect gene expression – molecular signatures.

NIMH’s Dr. Ann Wagner has been designed as the National Autism Coordinator. In this role, she will play a vital role in ensuring the implementation of national autism spectrum disorder research, services, and support activities across federal agencies.

Researchers have produced the first direct evidence that parts of our brains implicated in mental disorders may be shaped by a “residual echo” from our ancient past. The more a person’s genome carries genetic vestiges of Neanderthals, the more certain parts of his or her brain and skull resemble those of humans’ evolutionary cousins that went extinct 40,000 years ago.

Functional connectivity magnetic resonance imaging (fcMRI) may predict which high-risk, 6-month old infants will develop autism spectrum disorder (ASD) by age 2 years.

For the first time, neuroscientists have boosted a female rodent’s partnering with a male by stimulating connectivity of a brain reward circuit. Understanding the circuitry of such affiliative behaviors may lead to improved treatments for social impairment in severe mental disorders, such as autism spectrum disorder.

Neuroscientists have created a 3D window into the human brain’s budding executive hub assembling itself during a critical period in prenatal development.

Researchers have discovered a pattern of genetic glitches and behavioral features, such as delayed walking, in some cases of autism spectrum disorder (ASD) that could ultimately lead to identification of subgroups and improved treatment.

Researchers have narrowed suspected genetic causes of autism and related developmental disabilities by ruling out what they call the “noise of benign variation.”

Schizophrenia, autism risk gene trajectories point to shared causes

Two of the world’s largest brain tissue banks unify efforts to collect and distribute a critical number of brain donations for important autism research.

James McPartland, Ph.D. of Yale University will lead a new four-year $28 million Biomarkers Consortium project that aims to improve clinical evaluation of treatments for social impairment in children with autism.

Dr. Insel describes recent accomplishments related to autism spectrum disorder over the past year—from the reauthorization of the Interagency Autism Coordinating Committee to promising therapeutic results from clinical trials.

Many patients with psychosis develop health risks associated with premature death early in the course of their mental illness, researchers have found.

NIH-funded projects aim at improving access, timeliness of interventions.

Most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches.

The architecture of the autistic brain is speckled with patches of abnormal neurons, according to research partially funded by the National Institute of Mental Health, published in the New England Journal of Medicine on March 27, 2014.

The hippocampus houses learning and memory—specifically the storage of knowledge of who, what, where, and when. Using a special transgenic mouse, researchers have now pinpointed a hippocampal region called CA2 that is important for social memory, the ability of animal to recognize another of the same species. Understanding this region could be useful in understanding and treating disorders characterized by altered social behaviors such as schizophrenia, bipolar disorder, and autism.
