Which of the following is NOT a trait of PTSD?

A sense of extreme euphoria is not typically associated with post-traumatic stress disorder (PTSD). Instead, PTSD is characterized by symptoms that revolve around re-experiencing traumatic events, avoidance behaviors, negative changes in cognition and mood, and heightened arousal.

In contrast, sleep disturbance, hypervigilance, and aggression are recognized traits of PTSD. Individuals may struggle with insomnia or nightmares (sleep disturbance), exhibit an exaggerated startle response, or display persistent vigilance in their environment (hypervigilance) due to an ongoing sense of threat. Aggression can manifest as irritability or outbursts of anger, stemming from the heightened arousal and stress responses associated with PTSD. Thus, these traits directly correlate with the disorder, while a sense of extreme euphoria does not fit within the established symptomatology of PTSD.
