The Study
Physiology and neurobiology of stress and adaptation: central role of the brain.
This article is like a teacher summarizing what lots of other scientists have found about how stress affects the brain. It doesn't do new experiments, so it can't say for sure that stress causes brain changes—it just says many studies have noticed a connection.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
When you're stressed a lot, your brain changes: the part that helps you remember gets smaller, the part that makes you scared gets bigger, and this can make you forget things more easily or feel anxious.

People who went through tough experiences like abuse or neglect as kids are more likely to struggle with mood problems, memory issues, and stress as adults because their brains and bodies may have changed in lasting ways.
When your body releases a little bit of the stress hormone cortisol, it can help you remember things better. But if you're under stress for too long and have too much of it, it can actually damage your brain cells and make it harder to think clearly.
People who exercise regularly and have strong social connections tend to feel less stressed and handle life’s challenges better, maybe because their brains grow new cells, their bodies fight inflammation better, and their stress hormones work more smoothly.
When people are under long-term stress, parts of their brain that control memory and emotions can change shape—some areas shrink while others grow—which might make it harder to remember things, cause more anxiety, and make it tougher to control emotions.
When people are under long-term stress, it makes it harder for them to remember things and learn new stuff, but it makes them more prone to feeling scared or anxious—because stress changes the brain in opposite ways in two different areas.
