Perinatal Environment
Autism is associated with some perinatal and obstetric conditions. A 2007 review of risk factors found associated obstetric conditions that included low birth weight and gestation duration, and hypoxia during childbirth. This association does not demonstrate a causal relationship. As a result, an underlying cause could explain both autism and these associated conditions. A 2007 study of premature infants found that those who survived cerebellar hemorrhagic injury (bleeding in the brain that injures the cerebellum) were significantly more likely to show symptoms of autism than controls without the injury.
