UTSW study explores link between high school IQ and alcohol use

A person’s IQ during high school is predictive of alcohol consumption later in life, according to a study by UT Southwestern Medical Center researchers published in Alcohol and Alcoholism. Participants with higher IQ levels were significantly more likely to be moderate or heavy drinkers, as opposed to abstaining.

EARLY-LIFE AIRBORNE LEAD EXPOSURE ASSOCIATED WITH LOWER IQ AND SELF-CONTROL IN NIH STUDY

Children who lived in areas with higher levels of airborne lead in their first five years of life appeared to have slightly lower IQs and less self-control, with boys showing more sensitivity to lead exposure, according to a new study from the NIH Environmental influences on Child Health Outcomes (ECHO) Program.

Complications from diabetes linked to worse memory, IQ in children

A study led by UC Davis Health researchers uncovered that even one severe episode of diabetic ketoacidosis (DKA) in children newly diagnosed with type 1 diabetes is linked to cognitive problems; and among children with a previous diagnosis, repeated DKA exposure predicted lower cognitive performance after accounting for glycemic control.

Autism severity can change substantially during early childhood

A UC Davis MIND Institute study found that around 30% of young children with autism have less severe autism symptoms at age 6 than they did at age 3, with some losing their autism diagnoses entirely. It also found that girls tend to show greater reduction and less rise in their autism symptom severity than boys with autism. Children with higher IQs were more likely to show a reduction in their symptoms.
