DNA markers in low IQ autism suggest heredity – ASD

DNA markers in low-IQ autism suggest heredity – Researchers are striving to understand the different genetic structures that underlie at least a subset of autism spectrum disorders. In cases where the genetic code is in error, did that happen anew in the patient, perhaps through mutation or copying error, or was it inherited? A new study in the American Journal of Human Genetics finds evidence that there may often be a recessive, inherited genetic contribution in autism with significant intellectual disability.

Prenatal exposure to insecticide linked to decreases in cognitive functioning at age 7

Prenatal exposure to common insecticide linked to decreases in cognitive functioning at age 7 — Deficits in IQ and working memory suggest longer-term educational implications – Researchers from the Columbia Center for Children’s Environmental Health at the Mailman School of Public Health report evidence of a link between prenatal exposure to the insecticide chlorpyrifos and deficits in IQ and working memory at age seven.

Reducing diet in pregnancy may affect brain growth in fetus

Reducing diet early in pregnancy stunts fetal brain development — Study shows that the fetal brain is vulnerable to moderate decreases in maternal nutrition – Eating less during early pregnancy impaired fetal brain development in a nonhuman primate model, revealed by researchers from The University of Texas Health Science Center San Antonio.

Childhood lead exposure causes permanent brain damage

Childhood lead exposure causes permanent brain damage – A study using functional magnetic resonance imaging (fMRI) to evaluate brain function revealed that adults who were exposed to lead as children incur permanent brain injury. The results were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Spanked children may have lower IQs

Children who are spanked have lower IQs, new research finds – Children who are spanked have lower IQs worldwide, including in the United States, according to new groundbreaking research by University of New Hampshire professor Murray Straus.

Anesthesia during delivery does not affect learning in baby

Mayo researchers find anesthesia not harmful for babies during birth process – Children exposed to anesthesia during Cesarean section are not at any higher risk for learning disabilities later in life than children not delivered by C-section, revealed by researchers.

Epilepsy drug valproate during pregnancy lowers child’s IQ

Exposure to epilepsy medicine valproate during pregnancy can impair a child’s cognitive development and IQ. – Three-year-olds whose mothers took the antiepileptic drug valproate during pregnancy had average IQs six to nine points lower than children exposed to three other antiepileptic drugs, a landmark multi-center study has found.
