Autism is a disorder of the human nervous system that occurs because of brain abnormalities. Scholars found out that the parts of the brain responsible for the processing of the emotions don’t develop in the brains of the autistic people in the same way they do in the brains of non-autistic people. Additional evidence suggests that some of the connections between different areas of the brain may also not connect when a person has autism. For example, one autistic person may be extra-sensitive to fluorescent lights while someone else may be getting sick because of a strong smell. All of this depends on what circuits connect in their brains in which ways.
Autism is a very broad spectrum. On one end of it is severe autism. A child with severe autism will never learn to speak. On the other end is Asperger Syndrome, where children have no obvious speech impairments. Doctors and parents often don’t even recognize the syndrome unless a child has issues socializing with other kids. Some people with Asperger Syndrome are highly intelligent. Some famous scientists and musicians probably had the disorder.
The extensive variability of the autism spectrum happens because of all the different types of abnormalities that can occur in a human brain.
Many pediatricians don’t have any experience with autism, which is why they are clueless about its symptoms and don’t know what to look for. Uninformed doctors may tell parents that they are overreacting and that their children are just fine.
Autism is a condition. It does come with many challenges, but it’s not a mental illness or a result of bad parenting. Many people who have autism are able to live fulfilling and productive lives. Many autistic people have made great contributions to science, music, and art, including contributions to the understanding of the condition. Some people with autism are college professors who have doctorate degrees and are fully capable of fulfilling all the requirements of their jobs.
