Impact of Deployment on Hypervigilance
Research conducted on military deployment has shed light on the connection between hypervigilance and deployment. The findings of this study reveal that deployment alone can trigger hypervigilance, irrespective of the presence of post-traumatic stress disorder (PTSD). Surprisingly, even veterans without PTSD reported experiencing hypervigilance at a similar frequency to individuals with PTSD resulting from trauma unrelated to deployment. Moreover, the level of hypervigilance reported by these veterans was significantly higher than that reported by civilians without PTSD. These observations strongly suggest that the experience of deployment in a war zone is sufficient to induce hypervigilance, which persists even after returning to civilian life.
Functional Impairment
Implications of Hypervigilance on Functional Abilities
Hypervigilance has been found to be a reliable predictor of post-traumatic functional impairment. Several studies have demonstrated that early symptoms of hyperarousal, including hypervigilance, are indicative of limited improvement over time. While the exact causal relationship between hypervigilance and functional impairment remains uncertain, some researchers propose that hypervigilance, whether associated with post-traumatic stress disorder (PTSD) or not, can significantly impact social, psychological, and occupational functioning, thereby increasing the likelihood of unfavorable outcomes.
