Which PTSD symptom is most readily controlled with medication?

• A. Increased arousal
• B. Dissociations
• C. Avoidance behaviors
• D. Negative memories

Answer: (A)

The key idea is that medications for PTSD most reliably dampen physiological arousal rather than the cognitive-behavioral or memory aspects. Medications like SSRIs or SNRIs tend to reduce signs of hyperarousal—sleep disturbance, irritability, hypervigilance, and an exaggerated startle response—by calming the body's stress system. In some cases, drugs like prazosin can help with nightmares, a specific arousal-related symptom, but the core arousal symptoms are the ones most consistently improved with pharmacology. Dissociation and avoidance are more about how a person processes trauma and avoids reminders, which are behavioral and cognitive responses. These tend to respond better to psychotherapy, such as exposure-based or trauma-focused treatments, rather than meds alone. Negative memories, or intrusive re-experiencing, involve vivid, distressing recollections that meds can ease in terms of associated distress or sleep, but they’re not typically eliminated by medication alone; trauma-focused therapy often yields more substantial improvement in those symptoms.
