It’s in their eyes
IN THEIR EYES: Some autistic individuals have eye movement deficits, and a new study show that a similar pattern can be found in some of their close relations–even those who don’t have other signs of the disorder.
Researchers working at the University of Illinois at Chicago’s (U.I.C.) Center for Cognitive Medicine have found a striking trend: those with autistic relatives are more likely to show disrupted eye movement similar to their afflicted relation.
Large-scale genetic studies have turned up nuanced and conflicting results about the genetic basis of autism and its myriad symptoms. Other research has discovered that many people with an autistic relative or child might themselves have some subtle behavior variant as well, such as obsessive-compulsive tendencies or communication problems.
What percentage of the population have these eye movements, and how many of them have autism? Maybe the eye movements are not related to autism at all.
