As genetic testing becomes routine, people are likely to face difficult choices about parenthood.
High levels of serotonin in the womb may up the risk of autism in the child, according to a study published in December in the American Journal of Medical Genetics.
Mice exposed to an epilepsy drug show several features of autism, including abnormal social interactions, repetitive behaviors and patterns of super-fast brain waves, called gamma oscillations, according to a study published 15 December in Biological Psychiatry.
At birth, children with autism have lower blood levels of a class of antibody produced in response to infection compared with healthy controls, according to a report published in December in Autism Research.
Pregnant mice injected with the immune protein interleukin-6 give birth to pups that are less social than normal, an effect that results from the over-activation of two pathways critical in neurodevelopment, researchers reported Tuesday at the Society for Neuroscience annual meeting in San Diego.
The gene-environment interactions that are thought to contribute to many cases of autism can now be explored in a mouse model, according to a poster presented Sunday at the Society for Neuroscience annual meeting in San Diego.
Infection early in pregnancy is more harmful to the fetus than at later stages, triggering brain and behavioral changes in the offspring similar to those seen in people with schizophrenia, according to two mouse studies published in October. A third study suggests that exercise can mitigate some of these effects.
Two new studies use medical records from countries with nationalized health care to link autoimmune disease and obesity in parents to the likelihood of having a child with autism.
Chemicals produced by their mother’s immune system in utero alter the size of several key brain regions in people with schizophrenia, enlarging chambers that store cerebrospinal fluids, and shrinking parts of the cortex involved in processing emotion and memory.
