PTSD symptoms include recurrent distressing recollections and flashbacks. What does "hyper-vigilant" signify in this context?

In the context of PTSD, "hyper-vigilant" signifies a heightened state of awareness. This term refers to an individual’s increased sensitivity to their surroundings and a constant state of alertness, often resulting from the need to anticipate danger or threats based on past traumatic experiences.

Individuals with PTSD may be easily startled, have difficulty relaxing, or feel as though they are always on guard. This hyper-vigilance can lead to an overwhelming sense of anxiety and can impact their ability to engage in everyday activities. In contrast, the other choices describe states that do not align with the hyper-alertness associated with hyper-vigilance. For example, a lack of emotional response would indicate numbness rather than increased awareness, while a focused state of calm reflects relaxation, and an inability to concentrate indicates distraction, both of which are not characteristics of hyper-vigilance.
