The exact cause of autism is still not fully understood, but it is believed to be the result of a combination of genetic and environmental factors that influence brain development. Below are some factors that may contribute to the development of Autism Spectrum Disorder (ASD):

• Genetic factors: There are several genes that have been linked to autism, and it is believed that variations or mutations in these genes may increase a person’s susceptibility to developing the disorder. In some cases, autism can be hereditary and present in multiple family members.

• Environmental factors: Although no specific environmental causes have been identified for autism, certain factors during pregnancy and birth are believed to increase the risk of developing the disorder. These factors may include exposure to toxins, infections during pregnancy, advanced parental age, complications during childbirth, and low birth weight, among others.

• Brain changes: It has been observed that individuals with autism have differences in brain structure and function compared to neurotypical individuals. These differences may be the result of the interaction between genetic and environmental factors affecting brain development.

It is important to note that there is no single cause for autism, and the factors contributing to the development of the disorder may vary between individuals. Research into the causes of autism is an active and evolving area, and studies are being conducted continuously to better understand the underlying factors that contribute to autism.
