Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Using a new and more detailed approach to diffusion tensor imaging (DTI) recently developed in our lab, the investigators hope to learn more about irregularities in the brain that are related to autism. The investigators are especially interested in brain regions that contribute to repetitive behaviors in children with autism. Repetitive behaviors include stereotyped motor movements (hand-flapping), self-injurious behaviors (head hitting), compulsions (lining up toys), insistence on things staying the same, and difficulty with change. These behaviors often interfere with learning, can disrupt daily functioning, and can lead to other behavioral problems. Two specific aims will be accomplished: Aim 1: To examine the integrity of white matter pathways in high functioning autistic children. The investigators hypothesize that autism is associated with specific white matter abnormalities in the cerebellum and other motor circuits. Additionally, the investigators expect to confirm and expand on previous reports of cerebral abnormalities by using newly developed DTI methods. Aim 2: To determine whether there is a relationship between white matter abnormalities and the occurrence of restricted repetitive behaviors in children with autism. The investigators hypothesize that differences in the occurrence and type of restricted repetitive behaviors between autistic individuals are correlated with specific regional white matter abnormalities. Results from the proposed experiments should contribute to current knowledge of brain abnormalities in autism and their relationship to restricted repetitive behaviors, and may be relevant to understanding the mechanisms underlying motor deficits in this disorder.
