Depression linked to memory problems and brain aging

Depression in older adults may be linked to memory problems, according to new research. The study also showed that older people with greater symptoms of depression may have structural differences in the brain compared to people without symptoms.

Breakdown of brain’s visual networks linked to mental illness

Brain regions that help process what we see may play a key role in mental health. Researchers used brain imaging to identify patterns of brain connectivity — the ability of brain regions to talk to each other — that affect a person’s likelihood for d…

Stress helps unlearn fear

Stress can have a positive effect on extinction learning, which causes previously learned associations to dissolve. According to the findings of cognitive psychologists, stress causes extinction learning to occur independent of context. This might prov…
