Can birth asphyxia causes autism?
Summary: Children who were exposed to complications shortly before or during birth, including birth asphyxia and preeclampsia, were more likely to develop autism spectrum disorder, according to a study.
Can autism be caused by trauma at birth?
Birth injury or trauma increased autism risk fivefold. Babies with blood types incompatible with their mother’s had nearly four times the risk. Very low birth weight infants, or infants weighing less than 3.3 pounds at birth, faced triple the risk. Maternal hemorrhage more than doubled the odds.
Can prenatal stress cause autism?
There is preliminary evidence that prenatal maternal stress (PNMS) is a risk factor for both autism and attention deficit hyperactivity disorder (ADHD), however most studies do not control for confounding factors and no study has investigated PNMS as a risk factor for behaviors characteristic of these disorders in …
Can too much iron cause autism?

How long do people with autism live?
One of the most important investigations of recent years revealed that average life expectancy of a person with severe autism is 39.5 years, rising to only 58 years for those with high-functioning autism, or Asperger syndrome.
Is there an association between perinatal and neonatal factors and autism risk?
BACKGROUND: The etiology of autism is unknown, although perinatal and neonatal exposures have been the focus of epidemiologic research for over 40 years. OBJECTIVE: To provide the first review and meta-analysis of the association between perinatal and neonatal factors and autism risk. METHODS:
Does prenatal environmental stress increase risk for autism?
This paper reviews several converging lines of research that suggest that prenatal exposure to environmental stress may increase risk for Autistic Disorder (AD).
Is low birth weight associated with autism risk?
The positive association between low birth weight and risk of autism was also driven by 10 of 14 studies that assessed birth weight prospectively, suggesting that differential recall may have resulted in bias toward the null.
Is preterm birth associated with the risk of autism?
Overall, preterm birth was not associated with the risk of autism, although there was significant heterogeneity across studies. In 5 studies with broad diagnostic criteria, preterm birth was associated with a 76% increased risk, and in 10 prospective studies preterm birth conferred a 54% increase in risk.
