Which of the following is NOT a symptom of PTSD?

The choice indicating enhanced mood stability is not a symptom of PTSD, making it the correct answer to this question. PTSD is characterized by a range of symptoms that can significantly disrupt a person's emotional and psychological well-being.

Individuals with PTSD often experience emotional numbing, flashbacks, and severe anxiety related to their traumatic memories. Emotional numbness can lead to a lack of responsiveness to feelings and difficulty in experiencing positive emotions. Flashbacks involve reliving the traumatic event as if it were happening in the present, which can be very distressing. Severe anxiety manifests in a heightened state of distress and fear, often leading to hypervigilance and avoidance behaviors.

In contrast, enhanced mood stability would imply a sense of emotional resilience and control, which is typically contrary to the experience of someone suffering from PTSD.
