The exact cause of
autism is not known, but research has pointed to several factors: genetics (heredity); metabolic or neurological factors, certain types of infections, and problems occurring at birth.
In your child, environmental factors may also play a role.
Studies of scientists have found abnormalities in several regions of the brain, which suggest that autism results from a disruption of early brain development while still developing in the mother's womb.
Other autism theories suggest:
- immune theory -
antibodies that attack the brains , causing autism.
- abnormalities in brain structures cause autistic behavi
- abnormal timing of the growth of their brains.
