Exposure to even low levels of common chemicals called organophosphate esters can harm IQ, memory, learning, and brain development overall in young children.
Cognitive flexibility, an ability to switch between different concepts, or adapt behavior to achieve goals in a novel or changing environment, is a key player in both learning and creativity.
Prescribing SSRIs during late childhood to those with genetic risk factors for psychosis can reduce the deterioration of intellectual abilities, a new study reveals. SSRIs appear to have a neuroprotective effect for certain brain areas associated with the onset of psychosis if provided early.
Average IQ was significantly lower for adults who were born with either a very low birth weight or born very prematurely, a new study reports.
Independent of IQ, decision acuity predicted performance in decision-making tasks. This factored higher in older adults and increased in light of parental education.
A new computational model can identify genes linked to autism and predict the level of intellectual disability in people with ASD by only using rare mutations in genes already associated with the condition.
Verbal IQ, overall IQ, and brain volume are lower in children with type 1 diabetes than in their peers without the disorder. Researchers believe the cognitive and brain development differences are associated with hyperglycemia.
Frequent cannabis use was associated with a two point decline in IQ. The decline was primarily related to verbal IQ.
Children with autism show a significant increase in IQ scores between the ages of 12 and 23. Those with the greatest increases in IQ scores had early regressions in language and communication skills by the age of 12.
Higher levels of vitamin D during pregnancy were linked to increased IQ in children.
Study links diabetic ketoacidosis to lower IQ scores and worse memory in children with type 1 diabetes.
Severe adversity experienced in childhood increases the risk of being diagnosed with ADHD later in life.
