There may be an association between childhood infections and subsequent diagnoses of autism spectrum disorder (ASD) or intellectual disability (ID), according to a recent large-scale study.<\/p>\n<\/div>

H\u00e5kan Karlsson and colleagues analyzed data collected on 556,732 Swedish children born between 1987 and 2010, identifying all children with documented treatment for childhood infections. Their initial analysis showed a significant association between childhood infections and later
\nASD or ID, with the strongest association being for ID. When the researchers further analyzed their data by controlling for a wide range of variables, excluding children with congenital causes of ASD\/ID, and comparing the children with siblings to factor in both heritable and non-heritable factors, the
\nthe association was smaller but remained significant.<\/p>\n

The researchers conclude, \u201cBased on our analysis of the timing of infections and the diagnoses of ASD and ID in this study, including careful consideration of potential confounding by shared familial factors, we suggest that infections during early childhood contribute to risk of a later diagnosis of ID, including ID co-occurring with ASD.\u201d<\/p>\n
