This is going to upset the anti-VAX crowd, they were sure the culprit causing Autism and ADHD was vaccines, but it looks like it might just be the commonly used painkiller Tylenol. If taken during pregnancy there is a far greater risk of having a baby that will eventually suffer from Autism or ADHD.

Given how Tylenol has essentially replaced Aspirin as the pain killer of choice for most of the Western world it is no wonder that ADHD and Autism rates have not increased even more.



NIH-funded study suggests acetaminophen exposure in pregnancy linked to higher risk of ADHD, autism

Exposure to acetaminophen in the womb may increase a child’s risk for attention deficit/hyperactivity disorder and autism spectrum disorder, suggests a study funded by the National Institutes of Health and the Agency for Health Care Research and Quality. The study was conducted by Xiaobing Wang, M.D., of the Johns Hopkins University Bloomberg School of Public Health, Baltimore, and colleagues. It appears in JAMA Psychiatry.
Attention deficit/hyperactivity disorder (ADHD) is marked by a pattern of hyperactivity and impulsive behavior. Autism spectrum disorder (ASD) is a complex developmental disorder that affects how a person behaves, interacts with others and learns.
Researchers analyzed data from the Boston Birth Cohort, a long-term study of factors influencing pregnancy and child development. They collected umbilical cord blood from 996 births and measured the amount of acetaminophen and two of its byproducts in each sample. By the time the children were an average of 8.9 years, 25.8% had been diagnosed with ADHD only, 6.6% with ASD only and 4.2% with ADHD and ASD. The researchers classified the amount of acetaminophen and its byproducts in the samples into thirds, from lowest to highest. Compared to the lowest third, the middle third of exposure was associated with about 2.26 times the risk for ADHD. The highest third of exposure was associated with 2.86 times the risk. Similarly, ASD risk was higher for those in the middle third (2.14 times) and highest third (3.62 times).

Prenatal exposure to acetaminophen associated with ADHD and autism

An epidemiological study of more than 70,000 children in six European cohorts has linked symptoms of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum conditions (ASC) to the mothers' use of paracetamol (acetaminophen) during pregnancy. The study, published in the European Journal of Epidemiology, was led by the Barcelona Institute for Global Health (ISGlobal), a center supported by the la Caixa Foundation.
In total, the researchers analyzed 73,881 children for whom data were available on prenatal or postnatal exposure to paracetamol, at least one symptom of ASC or ADHD, and main covariates. Depending on the cohort, 14% to 56% of the mothers reported taking paracetamol while pregnant.
The study found that children exposed to paracetamol before birth were 19% more likely to develop ASC symptoms and 21% more likely to develop ADHD symptoms than children who were not exposed.
"Our findings are consistent with previous research," explained ISGlobal researcher Sílvia Alemany, lead author of the study. "We also found that prenatal exposure to paracetamol affects boys and girls in a similar way, as we observed practically no differences."
