Which of the following is a category of PTSD?

• A. Delusion
• B. Intrusion
• C. Obsession
• D. Compulsion

Answer: (B)

Intrusion is one category of PTSD because it describes the re-experiencing cluster, where traumatic memories intrude into daily life. This includes distressing memories, nightmares, and flashbacks that feel as if the event is happening again. These involuntary experiences are a hallmark of PTSD and distinguish it from other conditions. Delusions are fixed false beliefs seen in psychotic disorders, not PTSD. Obsessions and compulsions are typical of OCD, not PTSD. PTSD is understood in clusters, with intrusion, avoidance, negative mood/cognition changes, and arousal/reactivity; intrusion specifically refers to those involuntary, distressing re-experiencing symptoms.
