Age and Stress Can Lead to Short-Term Memory Loss
binära optioner nordea A new study by the University of Iowa (UI) has found that prolonged stress causes a surge in the hormone cortisol, which can result in short-term memory loss in older adults.
köpa Viagra på postförskott Short-term increases in cortisol are critical for survival, as they help to promote coping and help us respond to life’s challenges by making us more alert.1 However, abnormally high or prolonged spikes in cortisol, such as that which accompanies long-term stress, can lead to negative consequences, such as digestion problems, anxiety, weight gain, and high blood pressure.1
