Drug improves social deficits in fragile X syndrome
A drug called arbaclofen improves behavioral problems in people with fragile X syndrome, an inherited condition that can lead to mental retardation and autism, according to the results of a clinical trial published today in Science Translational Medicine. A second study published in the same journal showed that the drug restores normal brain function in a mouse model of the disorder.

IQ’s link to brain structure, function in children may be a mirage
A child’s socioeconomic status, screen time and amount of sleep all show stronger associations with measures of brain structure and function, according to an imaging study of nearly 12,000 9- to 10-year-olds.
