What does the research about autism provide?
Researchers believe that gene studies will help unlock the mystery of autism. In a study done by National Institutes of Health, the National Alliance of Autism Research, the Hussman Foundation and the Autism Genetic Resource Exchange analyzed 54 African American families and 557 Caucasian families in which a member had autism. Researchers studied the genes that regulate a brain chemical or neurotransmitter called GABA along chromosome 15. Chromosome 15 has been linked to autism. According to the researchers, GABA slows down nerve cells once their message has been transmitted to the brain acting as an information filter that prevents the brain from becoming over-stimulated. If the GABA system fails, the brain can be flooded with sensory information that overpowers the brain’s processing capabilities, leading to some of the characteristic behaviors of autism. The largest research for autism genes to date, funded by the National Institutes of Health (NIH), has implicated components of the
