Scientists are deep in the trenches discovering the factors involved in developing autism and how to effectively "retrain" the brain through intensive interventions. Director of Neuroscience Education and Adjunct Associate Professor at Northwestern University, Martha S. Burns, Ph.D., recently presented a webinar that provides the very latest information about the brain’s role in autism and how to intervene for favorable results. The FACTS: 1. Autism is Highly Heritable This means that autism is frequently, but not always, passed down from one generation to another. Because of the complexity of the human genome (DNA set), gene mutations can also be responsible for a child developing autism even if autism does not run in his or her family. 2. Autism is Not Caused by IQ Deficiency Two-thirds of those diagnosed with autism possess average or above-average intellectual ability. 3. Genes Overlap We see a genetic correlation of autism with other disordered traits such as depression and ADHD. 4. Brain Connectivity Problems Precede Autism Autism does not create brain connectivity problems. Instead, autism stems from an underdeveloped cerebral cortex, the part of the brain responsible for relaying and interpreting messages. There may be other causes as well, such as protein synthesis issues or core brain area dysfunction. For example, a dysfunctional hypothalamus, which regulates sleep, may play a role in the development of autism. 5. There is Still Much to Learn About How and Why Autism Develops Since every child’s DNA is unique and complex, the causes of autism are difficult to pinpoint. The INTERVENTION: 1. The Earlier the Diagnosis, the Better Autism Spectrum Disorder begins to develop in utero. Auditory scans performed on infants show that auditory brain stem response is slower in those with Autism Spectrum Disorder. We may be able to use this information to start early, intensive intervention, which benefits children […]
