Which of the following is NOT a possible cause factor of Autism?

The assertion that vaccinations are not a possible cause factor of autism is supported by extensive scientific research and evidence. Numerous large-scale studies have investigated the correlation between vaccinations, particularly the MMR (measles, mumps, and rubella) vaccine, and the incidence of autism. These studies consistently show no causal link between vaccinations and the development of autism spectrum disorders. The claim that vaccines may contribute to autism has been widely discredited and is considered a public health myth.

In contrast, genetics is a recognized factor, as there is considerable evidence indicating that autism tends to run in families, suggesting a hereditary component. Diet and the inability to metabolize certain foods have been explored as potential influences on autistic behaviors, particularly as some individuals may react negatively to specific diets or food components. Environmental factors, including exposure to certain toxins, have also been studied in relation to their potential impact on neurodevelopment, including autism.

By highlighting the lack of scientific support for the link between vaccinations and autism, it is clear why this is considered the option that does not represent a possible cause factor of autism.
