In older adults, which parameter is generally increased?

Aging tends to blunt sensory detection, so the threshold at which pain is perceived usually rises. Structural and functional changes in the nervous system—fewer small-diameter nociceptors, slower nerve conduction, and altered central processing—mean a higher intensity stimulus is required to evoke a pain signal. This higher pain threshold is the reason it’s identified as the parameter that tends to increase in older adults. In contrast, visual acuity commonly worsens, thermoregulation becomes less precise, and dopamine receptor density decreases, not increases. Keep in mind that older adults may still experience significant pain, but their threshold for sensing it is typically higher, which underscores the importance of thorough, multimodal pain assessment.
