There is ample evidence that autistic students have nothing to do with family background and parents' parenting attitude, nor are they caused by acquired environment. Autism may be caused by physiological factors, such as neural development, biochemical development, genetic factors or brain injury. Autism may be caused by physiological factors, such as neural development, biochemical development, genetic factors or brain injury. Possible causes of autism include:
heritage
From the research of family and twin children, it is found that about 10% to 20% of autistic twin brothers and sisters may have a slight autism tendency.

Be infected by a disease
During pregnancy, women may suffer from German measles or rubella, which may damage the brain development of the fetus and lead to autism.

In addition, metabolic diseases can also cause brain cell dysfunction, affect the function of brain nerve to transmit information, and thus lead to autism.

In addition, infant brain hypoplasia caused by embarrassing abortion during pregnancy, premature delivery, dystocia and neonatal brain injury, as well as brain injury caused by diseases such as encephalitis and meningitis in infancy, may increase the chance of autism.
Most autistic children don't speak much, even when they are serious, and they don't respond even if others call him loudly. I hope parents and friends will pay more attention to children's health problems.
