The causes of autism disorder are still unknown, but some factors may be common causes of autism. Learn about them as follows:
Are there really common causes of autism? Let''s get to know the details below
Common causes of autism
The exact cause of autism is not yet clear, as there is no single factor known as the definitive cause of autism, but it is believed that there are risk factors that increase the possibility of autism, which include:
1. Genetic factor
Genetic factor can affect the risk of some forms of autism.
A person is more likely to develop autism if he or she has a brother, sister, twin, or parent who also has autism.
Families who have a child with autism have a greater chance of giving birth to another child with the disorder.

Because autism runs in families, most researchers believe that certain sets of genes can predispose a child to develop autism.
In addition, parents or relatives who have a child with autism usually suffer from certain disorders in some developmental or developmental skills or even from certain subjective behaviors.
2. Disorder of the brain and nervous system
Some researchers believe that damage to the amygdala, a part of the brain that detects danger situations, may be one of the factors that trigger the onset of autism.
Researchers believe that there are genes, some of which affect brain growth and development and the way brain cells communicate with each other.
3. Pregnancy and childbirth
There is a belief that the critical period for the development of autism occurs before, during, and immediately after birth. When a pregnant woman is exposed to certain drugs or chemicals, her child is more susceptible to autism.
Also, alcohol consumption, maternal health problems, such as diabetes and obesity, and the use of anticonvulsant medications during pregnancy may increase the possibility of the child contracting the disease.
Some medications that women take during pregnancy, such as thalidomide and valproic acid, have been linked to an increased risk of developing the condition.
Complications of pregnancy and childbirth, such as: premature birth before 26 weeks, low birth weight of the baby, and twin pregnancies may also increase the chances of infection.
4. Some diseases
In some cases, autism has been linked to certain diseases, such as
Phenylketonuria, which is one of the metabolic disorders.
rubella.
Fragile
The neurological disorder known as Tourette syndrome.
Seizures.
Tuberous sclerosis and tuberous sclerosis.
5. Environmental factors
Researchers also believe that certain environmental influences may increase or decrease the risk of autism in people with a genetic predisposition to the disorder.
For example, there is a possibility that a viral infection, air pollutants, or exposure to heavy metals and environmental toxins may be one of the factors motivating the emergence and emergence of autism.
6. Age of parents
The advanced age of the mother or father increases the likelihood of giving birth to a child with autism, as researchers tend to believe that parenthood at a late age may increase the likelihood of developing autism.
It has also been shown that children born to parents over the age of forty are more likely to develop autism compared to children born to parents under the age of thirty.
7. Some vaccines
Despite the condescending voices on the subject, there is no reliable evidence that vaccines cause autism.
A study that raised controversy about the existence of a relationship between autism and some vaccines given to children, such as the MMR Triple vaccine, was retracted years ago due to the lack of credibility of the research methods used in it.
