Abstract

Cognitive and emotional impairment are a serious consequence of stress exposure and are core features ofneurological and psychiatric conditions that involve memory disorders. Indeed, acute and chronic stress arehigh-risk factors for the onset of post-traumatic stress disorder (PTSD) and Alzheimer’s disease (AD), two de-vastating brain disorders associated with memory dysfunction. Besides the sympathetic nervous system and thehypothalamic–pituitary–adrenal (HPA) axis, stress response also involves the activation of the opioid system inbrain regions associated with stress regulation and memory processing. In this context, it is possible that stress-induced memory disorders may be attributed to alterations in the interaction between the neuroendocrine stresssystem and the opioid system. In this review, we: (1) describe the effects of acute and chronic stress on memory,and the modulatory role of the opioid system, (2) discuss the contribution of the opioid system to the patho-physiology of PTSD and AD, and (3) present evidence of current and potential therapies that target the opioidreceptors to treat PTSD- and AD-associated symptoms.
