Brain imaging links language delay to chromosome deletion in children with neuro disorders

Children born with a DNA abnormality on chromosome 16 already linked to neurodevelopmental problems show measurable delays in processing sound and language, says a study team of radiologists and psychologists.

By strengthening the case that the deleted gene disrupts a key biological pathway, the research may lay the foundation for future medical treatments for specific subtypes of autism, along with cognitive and language disabilities.

Parental obesity and autism risk in the child

“We were very surprised by these findings because we expected that maternal obesity would be the main risk factor for the development of ASD. It means that we have had too much focus on the mother and too little on the father. This probably reflects the fact that we have given greater focus to conditions in pregnancy, such as the growth environment for the foetus in the womb than both environmental and genetic factors before conception,” says Surén.
