A new study finds that eye exams may help physicians diagnose sub-types of autism, Autism spectrum disorders (ASD) vary in level of severity and in how they are expressed symptomatically. The unpredictable nature of ASD creates many challenges for physicians trying to diagnose the disorder and also for treatment plans, as each individual responds differently. Being able to identify which phenotype of the disorder is presenting in the individual is an inherent first step to providing effective treatment.
New research has revealed that in a certain phenotype of ASD, the cerebellum—the part of the brain known for playing a part in motor control, emotions, and cognitive functions—is structured differently than in individuals without the disorder. In particular, the cerebellum is responsible for controlling rapid eye movements and the connection between the two may be used as an important tool by practitioners when trying to diagnose ASD in patients….
