Scientists find molecular player in Angelman syndrome

by  /  27 April 2010

Two independent teams have discovered key molecular steps in the way a single gene disrupts the connections between neurons in individuals with Angelman syndrome. Because the gene, UBE3A, has also been linked to autism, the findings could help scientists understand and treat a range of neurodevelopmental disorders.

Autism symptoms emerge in infancy, sibling study finds

by  /  6 April 2010

At 6 months of age, babies who will later develop autism begin to lose some of their social skills and continue to regress until age 3, according to a study published in the Journal of the American Academy of Child & Adolescent Psychiatry.

Delay found in development of fragile X brains

by  /  26 March 2010

Young mouse models of fragile X syndrome show a significant lag in the development of synapses, the connections between neurons, according to a study published in Neuron. The findings suggest that a similar mistiming may be responsible for the sensory problems — such as hypersensitivity to touch and sound — sometimes seen in people with fragile X syndrome.

Virtual games teach real-world skills to kids with autism

by  /  21 December 2009

Astropolis, a dynamic video game, allows for the unprecedented testing of children with autism on a variety of cognitive skills, all at once, without the artificial, boring and anxiety-ridden setup of a typical psychology lab.

Autism shares features with cerebellar syndromes

by  /  3 December 2009

There are clinical, anatomical and genetic overlaps between autism and certain rare developmental disorders of the cerebellum, and these disorders may help scientists understand autism, according to several studies published in the past year.

Baby sib studies reveal differences in brain response

by  /  30 November 2009

Studies on younger siblings of children with autism are finding that during tests of sensory or perceptual processing, these baby sibs show abnormally fast brain responses, rather than a delay.

Loss of inhibitory neurons marks autism mouse models

by  /  24 November 2009

Autism may be the result of faulty wiring that occurs during early brain development, according to two independent studies that looked at the origins of circuit disruption.

Neuroligin mutation triggers oxidative stress

by  /  20 October 2009

Deleting a neuronal protein associated with autism causes oxidative stress — characterized by an excess of free radicals — which has been linked to diseases such as diabetes and Alzheimer’s, according to new research in worms. The results were presented yesterday at a poster session at the Society for Neuroscience meeting in Chicago.

Beyond mirror neurons

by  /  20 November 2008

High-functioning children with autism may understand another personʼs intention when, for example, that person reaches for a glass of water ― a simple, goal-directed task ― without help from the mirror neuron system, according to research reported Tuesday at the Society for Neuroscience meeting.

GAP43 mutant mice mimic autism

by  /  17 November 2008

Mice missing a copy of GAP43, a gene involved in the development of axons ― the thin strands that conduct electrical signals between nerve cells ― show biological and behavioral parallels to autism, according to unpublished research presented in a poster session today at the Society for Neuroscience conference.
