Final answer:
Chronic stress is linked to negative health outcomes such as cognitive decline, emotional disturbances, and impaired immune function, but not memory enhancement.
Step-by-step explanation:
Chronic stress may cause structural degeneration and impaired function of the brain, increasing the risk for several health issues. However, one effect it does not promote is memory enhancement. Instead, chronic stress is associated with a range of negative outcomes, including cognitive decline, emotional disturbances, and impaired immune function. The field of psychoneuroimmunology further explains how stress negatively affects health by illustrating the interconnectedness of the nervous, endocrine, and immune systems.
