What are the Cause Of Autism?
Autism Spectrum Disorder is a neuro-developmental disorder, that can affect behavior, memory, communication, and learning.
Autism is complex disorder, and no two autistic people are similar. Due to this, experts believe there are probably many causes of autism, including genetic and environmental causes.
Many autistic people see autism as part of their identity , not as a condition to be treated or prevented, but some of themare centered around prevention.Other autistic people and advocates suggest research and resources to support autistic people.
Genetic cause of Autism Spectrum Disorder (ASD)
Many researchers believe genes play the biggest role in causing autism. While study suggests that many autistic people have small mutations in a lot of their genes, it’s not always clear how big or small of a role these mutations play.It means various mutations probably play different roles in causing autism.
Such as, some mutations or combinations of mutations could:
- play a role in causing definite behaviors
- contribute to requirement of minimal or significant support
- increase a person’s probability of having autism
Other genetic risk factors that may increase the chances of developing autism include:
- assigned male child at birth
- Child with autistic sibling
- a chromosomal condition such as fragile X syndrome.
Environmental causes for ASD
Some experts suggests that the most influential factors that increase a child’s chances of developing autism are related to what happens before and during birth, like if:
- the child is exposed to air pollution or certain pesticides before birth
- the pregnant mother has diabetes or any other immune system disorder
- the child is born before 36 weeks old
- Any birth complications like the baby was breech, in fetal distress, or had a low birth weight baby
- If any issues during birth that caused a limited amount of oxygen to the baby’s brain
These risk factors don’t cause autism by themselves. For instance, many children are born before 36 weeks, with and without autism.

Biological causes of ASD
Experts have also considered other biological factors connected to autism. These factors are involved with:
- Brain Connectivity
- Undergrowth or over growth in some areas of the brain
- Metabolism (the way body produces energy)
Some experts suggests that some infections during pregnancy could increase the child’s risk of having autism. Several other immune issues may also increase risks, including:
- Challenges with how the immune system works
- Developing antibodies to a situation where they haven’t been exposed to
Experts have found that there may be a link between mitochondrial function and autism.
Some other causes for ASD?
Other risk factors for developing ASD include:
- The frontal cortex of the baby’s brain overgrows shortly after birth
- Autism is 4 times more common in boys than girls
- Increased parents age
- If the parents had hypertension or diabetes
- Mother has given birth to more than 4 children
- Mother had pre-eclampsia
Do vaccines cause of Autism Spectrum Disorder (ASD)?
Some people say that vaccines cause autism, but it isn’t true.
According to Centers for Disease Control & Prevention, there’s no evidence that vaccines cause autism.
This assumption comes from a study published in the British medical journal, Lancet, in 1998. It tells that the measles, mumps, and rubella (MMR) vaccine caused autism.
But the study wasn’t properly conducted, and it was later disproven. But it got a lot of publicity, and some people still believe that these false findings are true.
Other risk factors, like smoking during pregnancy, exposure to mercury, or fertility treatments are also supposed to cause autism. None of these causes have been proven.
Causes of ASD are not known that is why prevention of Autism not possible,But if you’re facing challenges related to being autistic, there are many ways to find support, depending on your requirement.
