Signs & Symptoms
Autism’s core symptoms accompany a constellation of subtle signs that scientists are just beginning to unmask.
Adolescents with autism can gauge the direction of moving objects just as well as healthy controls can, but their confidence in their visual ability is sometimes misplaced, according to unpublished data presented yesterday at the IMFAR 2010 conference in Philadelphia.
Children with Williams syndrome — a rare genetic disorder that leads to mental retardation and overt friendliness — hold stereotypes based on gender, but not race, according to a report published in Current Biology. Because those with Williams syndrome don’t have social fear, the study suggests racial stereotypes are based partly on fear.
Variations in two genes needed to form connections between brain cells may be associated with autism spectrum disorder, according to a study published 25 March in Molecular Autism. Some variants in the genes seem to increase susceptibility to autism, whereas others protect children from developing the disorder.
Mirror neurons, which fire when someone either performs an action or observes it, are not defective in people with autism, scientists report today in Neuron. The findings dispute the theory that flaws in the mirror neuron system give rise to the disorder.
