Stress is a weapon of mass destruction against our ability to remember things

A University of Hamburg study found acute stress impairs the brain’s ability to connect new information with old memories.

In tests with 121 adults, stressed participants were much worse at inferring indirect links after learning related image pairs on two days.

fMRI showed stress reduced memory reactivation in the hippocampus and led to more separate, less integrated memory representations.

The findings suggest stress can hurt not just recall or mood, but everyday reasoning and learning.
