For a diagnosis of Post-Traumatic Stress Disorder (PTSD), what symptom is commonly observed?

The presence of markedly decreased interest or anhedonia is an important symptom observed in individuals diagnosed with Post-Traumatic Stress Disorder (PTSD). This symptom reflects the emotional numbness and disconnection that can occur following a traumatic event. Individuals with PTSD may experience a significant reduction in their ability to feel pleasure in activities they once enjoyed, contributing to a sense of detachment from their surroundings and relationships.

This symptom aligns with the broader diagnostic criteria of PTSD, which include avoidance of reminders of the trauma, negative alterations in cognition and mood, and heightened arousal and reactivity. In addition, the emotional symptoms often lead to challenges in personal, social, and occupational functioning, which are critical components to consider in a PTSD diagnosis.

The other symptoms detailed in the choices represent conditions that are more characteristic of different psychiatric disorders, such as obsessive-compulsive disorder and generalized anxiety disorder, rather than PTSD. Thus, the identification of markedly decreased interest or anhedonia as a common symptom in PTSD is consistent with the established diagnostic framework.
