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...

Prospective preference assessment for the Ecstasy for Alleviating Severe Chronic Neuropathic Pain (EASE-Pain) trial.

Canadian journal of anaesthesia = Journal canadien d'anesthesie September 1, 2025 Mindy Lu, Victoria Tucci, Nandana D. Parakh et al.

Emerging evidence suggests that 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy may be a promising intervention for chronic pain. We designed the Ecstasy for Alleviating Severe Chronic Neuropathic Pain (EASE-Pain) trial, a randomized controlled trial comparing MDMA with an active placebo (methylphenidate) for pain relief. We sought to conduct a prospective preference assessment...

This study, based on a secondary evaluation of two randomized controlled trials (RCTs) with student participants, was aimed at...

Prospective Preference Assessment for the Psilocybin for Enhanced Analgesia in Chronic nEuropathic PAIN (PEACE-PAIN) Trial

Canadian Journal of Pain November 8, 2024 Jiwon Lee, Kaylyssa Philip, Hance Clarke et al. 3 citations

The PEACE-PAIN trial study design is supported by patient survey responses but may benefit from modifications, namely incorporating thorough discussions of the current evidence for efficacy, safety, tolerability, and approaches to address adverse effects of psilocybin. Additionally, the interest in participation by individuals with prior psychedelic use holds important methodological...

Internet-based cognitive behavioral therapy (CBT) and stand-alone mindfulness meditation interventions are gaining empirical support for a wide variety of mental health conditions. In this study, we test the efficacy of web-based therapist-guided mindfulness-based cognitive behavioral therapy (CBT-M) for body dysmorphic disorder (BDD), a psychiatric disorder characterized by preoccupations with...

Chronic pain affects approximately 8 million Canadians (~20%), impacting their physical and mental health while burdening the health care system with costs of upwards of US $60 billion a year. Indeed, patients are often trialed on numerous medications over several years without reductions to their symptoms. Therefore, there is an urgent need to identify new therapies for chronic pain to improve...
