Both psychological and physiological factors cause anxiety neurosis, and evidence of a genetic influence exists. Physiologically, the symptoms of anxiety are the direct manifestation of peripheral autonomic nervous system discharge often triggered by the arousal of frightening impulses, images and emotions. In the CNS, noradrenergic transmitters play a prominent role in the production of anxiety, and recent studies point to the locus ceruleus as an important mediating center. These symptoms include heart palpitations, sweating, fear, generalized motor weakness and dizziness, nausea and occasionally diarrhea. Treatment for anxiety includes finding the source of the anxiety and deciding on a course of management.
