PAINscape—Exploring patient experiences with ketamine for chronic neuropathic pain: A qualitative study

Canadian Journal of Pain March 4, 2026 Nandana D. Parakh, Danielle Lessor, Kevin Dang et al.

Although pain experiences differed among participants, all participants reported decreased pain with ketamine infusions. Addressing the stigma associated with ketamine infusions, further research around augmenting durability of ketamine, and providing a safe treatment environment can all improve ketamine's benefit for chronic neuropathic pain. Understanding the barriers and facilitators, as...

Individuals with tension and migraine headaches exhibit increased heart rate variability during post-stress mindfulness meditation practice but a decrease during a post-stress control condition - A randomized, controlled experiment.

International Journal of Psychophysiology December 2016 Muhammad Abid Azam, Joel Katz, Vina Mohabir et al.

Current research suggests that associations between headache conditions (migraine, tension) and imbalances in the autonomic nervous system (ANS) are due to stress-related dysregulation in the activity of the parasympathetic-sympathetic branches. Mindfulness meditation has demonstrated effectiveness in reducing pain-related distress, and in enhancing heart rate variability-a vagal-mediated...
