Stress is a huge part of life. Our body responds to stress in different ways and most of the times the body overcomes the stress. There are a few incidents when the body is not capable of dealing with the stress and the toll it takes on the brain is undeniable. One result of intolerable stress is Dissociative Identity Disorder (DID) in which biopsychology comes to life, as we see how the body is affected by psychology, and vice versa. The mediators that help the body adapt to stressors become detrimental when a person faces trauma or chronic stress. Glucocorticoids, cortisol, and glutamate are all involved in either helping the body endure stress or causing plasticity in parts of the brain that are essential to being mentally healthy. This paper delves into the nature of DID, and how stress creates changes in the hippocampus and amygdala, the two parts of the limbic system that are smaller in patients with DID.
