Higher levels of vitamin D during pregnancy were linked to increased IQ in children. Read More
Study links diabetic ketoacidosis to lower IQ scores and worse memory in children with type 1 diabetes. Read More
Severe adversity experienced in childhood increases the risk of being diagnosed with ADHD later in life. Read More
Efficient connection pathways across the entire brain provide a neural network that supports general cognitive function and ability. Higher fractional anisotropy is associated with higher IQ. Read More
Exposure to flame retardants and pesticides resulted in more than a million cases of intellectual disability in children between 2001 and 2016. However, adverse outcomes from exposure to mercury and lead fell significantly during the same period. Read More
Young adults who faced extreme deprivation as children had, on average, an 8.6% smaller brain size than their peers who did not suffer from deprivation. The deprivation related changes in brain volume were associated with lower IQ and increased ADHD symptoms. Read More
Obesity during pregnancy was associated with lower IQ among boys, but not girls, at age 7. The findings suggest maternal obesity has long=term implications for early cognitive development. Read More
The ability to select specific traits, such as height or IQ, brought about by multiple genes is more complicated than most people realize. Read More
Higher intelligence was associated with higher temporal stability of brain network modularity. Brain regions of the dorsal attention network contributed most to the observed effect. Read More
Study finds an association between acetaminophen use during mid-to-late pregnancy and increased risk of hyperactivity, attention problems, and other behavioral deficits in young children. Boys appear to be more susceptible to the adverse effects acetaminophen use during pregnancy. However, the negative effects only seem to persist during the early years of life. Read More
Maternal exposure to higher levels of air pollution is associated with lower IQ scores in their children. For those whose mothers were in the highest 10% of exposure had IQ score that were, on average, 2.5 points lower than those whose mothers were in the lowest 10%. However, higher maternal folate levels appear to neurtralize the effect of high pollution exposure on offspring. Read More
Children with the APOE E4 gene perform lower on verbal and general IQ tests than their peers without the genetic risk factor. APOE E4 is a genetic risk factor for Alzheimer's disease. The study suggests the effects of the gene manifests before adulthood and could be the earliest biomarker for later vulnerability to Alzheimer's disease. Read More
