The Claim
Chronic psychological stress is associated with structural remodeling in the hippocampus, amygdala, and prefrontal cortex, including dendritic atrophy in the hippocampus and prefrontal cortex and hypertrophy in the amygdala, which may contribute to impaired memory, increased anxiety, and reduced emotional regulation over time.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.

What the research says
1 studyStudy: Physiology and neurobiology of stress and adaptation: central role of the brain.
Chronic stress can change the shape and size of brain areas that control memory, fear, and emotions—making the hippocampus and prefrontal cortex shrink and the amygdala grow, which can make you forget things more easily, feel more anxious, and have a harder time staying calm.
