Task: Answer Verification
Input (English): Question: Does posttraumatic stress disorder influence the nociceptive and intrathecal cytokine response to a painful stimulus in combat veterans?
Answer: These findings show significant central nervous system (CNS) differences in the inflammatory response to a deep pain stimulus in combat veterans with and without PTSD. They support the concept that abnormally elevated neuroinflammatory response to pain stimuli may be one CNS mechanism accounting for the high co-occurrence of PTSD and pain.
Output (English): yes
