Week 4: Anxiety Disorders, PTSD, and OCD

Your own experiences might tell you that expectations from family, friends, and work—as well as your own expectations regarding achievement, success, and happiness—can create stress. Stressors are a normal part of life, and stress traditionally has been viewed as an adaptive function with a set of physiological responses to a stressor. In a situation where stress is perceived, the organism is physiologically prepared to attack or flee from the threat. Those with effective fight or flight responses tended to survive long enough to reproduce, so we are descended from those who are genetically hardwired for self-protection. When you experience stress, your biology, emotions, social support, motivation, environment, attitude, immune function, and wellness all feel the ripple effect.

This stress response is an adaptive response the human body has to threats; however, stress can also be difficult to handle and—depending upon the nature and intensity of the stress—can result in anxiety disorders, obsessive-compulsive disorders, or trauma- and stressor-related disorders. This week, you will focus on these disorders and explore strategies to accurately assess and diagnose them.
