"An enhanced state of sensory sensitivity accompanied by an exaggerated intensity of behaviors whose purpose is to detect threats. Hypervigilance is also accompanied
by a state of increased anxiety which can cause exhaustion. Other symptoms include abnormally increased arousal, a high responsiveness to stimuli, and a continual scanning of the environment for threats.
In hypervigilance, there is a perpetual scanning of the environment to search for sights, sounds, people, behaviors, smells, or anything else that is reminiscent
of threat or trauma. The individual is placed on high alert in order to be certain danger is not near.
Hypervigilance can lead to a variety of obsessive behavior patterns, as well as producing difficulties with social interaction and relationships."
