Childhood trauma may affect brain structure, predisposing adults to recurring major depressive disorder
by Lancet Credit: CC0 Public Domain Early life trauma may affect the structure of the brain in a way that makes clinical depression more likely to be severe and recurrent, according to a two-year observational study of 110 patients published in The Lancet Psychiatry journal. Previous studies have suggested an association between maltreatment and altered brain structure, while...

Immune profile two days after stroke predicts dementia a year later
Stanford researchers have found that transient changes in the numbers and activation levels of a handful of circulating immune cell types can predict the likelihood of dementia one year after a stroke. A pattern of inflammatory activity in circulating blood cells two days aftera stroke strongly predicts the likelihood of losing substantial mental acuity one year later, investigators at the Stanford University School of Medicine report in a new study. The findings, based...
