The amygdala detects stress in the environment, while the prefrontal cortex regulates our reactions to stress.

What causes HPA axis dysfunction?

Usually the root cause of HPA axis dysfunction is inflammation due to a variety of stressors, including emotional stress (at home or work), undiagnosed infections, exposure to environmental toxins (such as toxic mold) and pollutants, and food sensitivities or poor diet.

What are stress triggers?

Main types of stress Stressors are events or conditions in your surroundings that may trigger stress. Your body responds to stressors differently depending on whether the stressor is new or short term — acute stress — or whether the stressor has been around for a longer time — chronic stress.

The sympathomedullary pathway (SAM pathway) is the route through which the brain directs the sympathetic branch of the autonomic nervous system (ANS) to activate in response to short-term stress.

What is HPA axis?

The hypothalamic-pituitary-adrenal axis (HPA axis) is an interactive neuroendocrine unit comprising of the hypothalamus, the pituitary gland, and the adrenal glands. … The HPA axis plays key roles in basal homeostasis and in the body’s response to stress.
