Stress affects the brain, particularly memory, but the effects differ significantly depending on whether the stress is acute or chronic.
Effect of Acute Stress on Memory and Concentration. Studies indicate that the immediate effect of acute stress impairs short-term memory, particularly verbal memory. On the plus side, high levels of stress hormone during acute stress have been associated with enhanced memory storage and greater concentration on immediate events. Cortisol, which is released by your pituitary gland, is particularly harmful to the brain. The question “How Does Stress Affect the Brain?” can be answered simply with one word – cortisol. This hormone is responsible for damaging brain cells after prolonged exposure. Studies have shown that cortisol can break down cells in the hippocampus, which controls your episodic memory. It has also been linked to premature brain aging. Although cortisol is important in helping your body overcome real threats, it should not be in the bloodstream as much as it is when you are under chronic stress.
