When Blood Pressure Talks to the Brain: How Hypertension Shapes Pain Perception
Recent studies reveal that baroreceptor signals linking blood pressure to the brain also modulate pain perception. Higher arterial pressure activates baroreflex pathways that dampen acute pain, while chronic pain conditions appear to exhaust this protective mechanism. Experiments using artificial baroreflex stimulation and lower‑body negative pressure show divergent responses in healthy versus chronic‑pain participants. The findings suggest new diagnostic and therapeutic avenues, from screening for silent myocardial events to neuromodulation‑based pain relief.
