Man scratching his head wondering how stress impairs memoryStress is the main culprit behind Adrenal Fatigue Syndrome (AFS), and it affects every component of the NeuroEndoMetabolic (NEM) Stress Response system that runs through our body. Slowly but surely, stress will shut down bodily functions until one's quality of life diminishes and it eventually results in death. It is truly deserving of its name as the “silent killer”. But what many people do not know is that stress impairs memory as well. Studies have found that chronic stress affects both working memory and response inhibition.

The Science Behind Why Stress Impairs Memory

If you’ve found yourself under stress and feel as though you’ve become rather forgetful, you are not alone. Although memory loss could be caused by a wide variety of ailments, a new US rat study by Zhen Yan, PhD, at the State University of New York at Buffalo, discovered that stress impairs memory. When the rats were exposed to repeated stress, they had significant impairment of memory and cognitive processing.

The stress in the lab rats caused a deficit in the glutamate receptors found in the prefrontal cortex that controlled high-level functions like decision-making, working memory, and memory loss.

In humans, the prefrontal cortex is also associated with risk-assessment and reward, decision-making, compulsive behavior, and self-awareness. It is a highly sensitive area in response to repeated stressors.
