Hypervigilance

Nervous system condition

Hypervigilance is a condition in which the nervous system is inaccurately filtering sensory information and the individual is in an enhanced state of sensory sensitivity. This appears to be linked to a dysregulated nervous system which can often be caused by traumatic events or PTSD. Normally, the nervous system releases stress signals in certain situations as a defense mechanism to protect one from perceived dangers. In some cases, the nervous system becomes chronically dysregulated, causing a release of stress signals that are inappropriate to the situation, creating inappropriate and exaggerated responses. Hypervigilance may bring about a state of increased anxiety which can cause exhaustion. Other symptoms include high responsiveness to stimuli and constant scanning of the environment.
