A detailed study of four mouse models of autism challenges the most common assumption about what goes wrong in brain circuits to cause disease symptoms. The major hypothesis today — one supported by many animal studies — has been that neurons in the autistic brain receive too little inhibition or too much excitation, which causes…

Early adult general cognitive ability (GCA) — the diverse set of skills involved in thinking, such as reasoning, memory and perception — is a stronger predictor of cognitive function and reserve later in life than other factors, such as higher education, occupational complexity or engaging in late-life intellectual activities, report researchers in a new study…

The findings, which were published today in the…

New research indicates that cancer survivors carry greater financial burdens related to medical debt payments and bills compared with individuals without a cancer history, with the greatest hardships in younger survivors. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study also found that among privately insured survivors, those who…
