Summary
Chronic pain afflicts an estimated 1.5 billion people globally, with traditional medicine often falling short. Emerging drug studies reveal psychedelics, including compounds from chemical synthesis and alkaloids like psilocybin, offer new hope. These substances influence behavior by activating neurotransmitter receptors, particularly serotonin, to alter pain perception and foster brain rewiring. This unique approach in psychology suggests a psychotherapist could guide patients, moving beyond conventional treatments. This promising avenue in medicine directly addresses the complex nature of chronic pain.
Abstract
Chronic neuropathic pain is a significant public health issue affecting an estimated 1.5 billion individuals worldwide. The mechanisms underlying chronic pain are multifaceted and not fully understood. Chronic pain amplifies specific neural pathways through peripheral and central sensitization triggered by repeated exposure to noxious stimuli, ultimately resulting in physical and emotional pain. Traditional treatment options targeting these mechanisms, such as opioid and non-opioid analgesics, are associated with adverse effects, addiction, and suboptimal pain relief. Using psychedelics to treat chronic pain is an area of growing interest. While psychedelic substances, such as psilocybin, lysergic acid diethylamide, mescaline, and 3,4-methylenedioxymethamphetamine are primarily associated with recreational use or spiritual practices, emerging evidence suggests their potential therapeutic benefits for various mental health disorders, including chronic pain. Psychedelics alter pain perception by directly activating serotonin receptors, exerting anti-inflammatory effects, enhancing descending inhibition, opening a window of neuroplasticity, and facilitating synaptic remodeling. This review mainly elucidates the ongoing research regarding the psychedelic mechanisms of action, pharmacology, clinical applications, and therapeutic potential in treating neuropathic pain.
