Researchers find new signs of stress damage in the brain, plus hope for prevention

Researchers find new signs of stress damage in the brain, plus hope for preventionNew research shows that when mice experience chronic stress, neurons within part of their brain’s fear and anxiety center, the amygdala, retract. It also suggests how such changes could be prevented. More »

An experimental Alzheimer’s drug reverses genetic changes thought to spur the disease

An experimental Alzheimer’s drug reverses genetic changes thought to spur the diseaseWhen given to old rats, riluzole reversed many age-related changes that occur in a brain region key to learning and memory. This drug also produced effects opposing those seen in the brains of Alzheimer’s patients. More »

Newly discovered windows of brain plasticity may help with treatment of stress-related disorders

Newly discovered windows of brain plasticity may help with treatment of stress-related disordersEven under repeated stress, the brain maintains the potential to adapt and recover. Researchers have shown how changes in gene expression cause these transitory opportunities to open up. Their results suggest well-timed treatment could change the trajectory of a brain suffering from depression or other disorder. More »
