Risk of first-time cardiovascular disease may be increased by vital exhaustion

Fatigue, increased irritability and feeling demoralized — a combination known as vital exhaustion — may raise the risk of first-time cardiovascular disease in otherwise healthy men and women…

Scientists prevent memory problems caused by sleep deprivation

Scientists have found that a particular set of cells in a small region of the brain are responsible for memory problems after sleep loss. By selectively increasing levels of a signaling molecule in these cells, the researchers prevented mice from havin…

Seniors draw on extra brainpower for shopping

Holiday shopping can be mentally exhausting for anyone. But a new study finds that older adults seem to need extra brainpower to make shopping decisions — especially ones that rely on memory. The study suggests that older shoppers draw on resources fr…

Songbirds help scientists develop cooling technique to safely map human brain

A new diagnostic technique — resulting from monitoring thousands of courtship calls from songbirds — can be used to safely map the human brain during complex neurosurgery, according to research.

Chronic alcohol intake can damage white matter pathways across entire brain

Chronic misuse of alcohol results in measurable damage to the brain. A new study uses high-resolution structural magnetic resonance scans to compare the brains of individuals with a history of alcoholism versus those of healthy light drinkers. The abst…

Youths with a family history of substance use disorders have less efficient forebrain

Youths with a family history of alcohol and other drug use disorders have a greater risk of developing substance-use disorders (SUDs) themselves than their peers with no such family histories. A new study examines forebrain activity in youths with and …

High-fructose diet in adolescence may exacerbate depressive-like behavior

When animals consume a diet high in fructose throughout adolescence, it can worsen depressive- and anxiety-like behavior and alter how the brain responds to stress. “Our results offer new insights into the ways in which diet can alter brain health and …

Mothers comforting babies in pain actually changes the gene activity in infants’ brains

Study on rats show that hundreds of genes in baby rats’ brains were more or less active, depending on whether the mothers were present while the babies were in pain.
