Document Summary
This brings about the fight or flight response that helps prepare our bodies to deal with an immediate threat. The symptoms of anxiety and fear can overlap to varying degrees, and in practice they are very difficult to tell apart. Apprehension/worry about real or perceived future threats. Emotional and physiological reaction to real or perceived immediate threats. Fear is an immediate alarm reaction to present danger, characterized largely by a strong motivation to escape. The fear response activates the sympathetic nervous system and the sympatho-adrenomedullary (sam) axis (see the stress lecture for a reminder). Anxiety and fear are not the same thing, but they are inter-related in some interesting ways. Disorders such as generalized anxiety disorder (gad) consist mostly of anxiety. On the one hand, anxiety is an emotional state that is a fundamental component of nearly every mental illness in the dsm. On the other hand, anxiety can be its own disorder, neatly separated from the others.
