What are the Likely Causes of Autism?

Autism Kid

Having received numerous interests on the subject ‘autism’, I decided to write a follow-up on my previous article titled “Living with autistic children.” Autism is one of the ailments that affect millions of children worldwide. Whereas there are no known causes for autism, doctors believe that the disorder is triggered by genetic factors. Recent studies into likely autism causes convincingly imply that particular individuals are genetically predisposed to the condition. Other likely triggers entail irregular levels of neurotransmitters inside the brain. Environmental factors have also been thought to play a role in autism causes and symptoms.

Family factors

In families that have an autistic child, the danger of having second autistic child with the syndrome is roughly 5%. This translates to 1 in every 20 children. Scientists are searching for clues regarding the genes that influence increased vulnerability. In a number of instances, parents and relatives with an autistic child display trivial impairments not only in social, but also communication skills. If you are keen, you will notice that such people have repetitive behaviors. Testimonies also imply that a number of emotional disorders, for example, maniac depression, appears more often in families with autistic children.

Scientists have also been able to disapprove the age old theory that parental practices are accountable for autism.


Certain studies imply that persons suffering from autism tend to have unusual amounts of serotonin in their brains. These anomalies imply that autism can be caused as a result of disturbance of normal brain growth during the initial stages of fetal development triggered by flaws in the genes responsible for controlling brain development as well as the genes that control how neurons correspond with one another. Whereas these revelations are interesting, it is important to point out that they are preliminary and still need further research.
