Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Chronic pain is a serious public health problem with estimates as high as nearly half of the adult population experiencing some form of pain that lasts for more than 6 months. Chronic use of opiates is a rapidly escalating crisis in the United States, with over 4.3 million Americans dependent on opiate analgesics, an escalating rate of opiate overdose deaths, and a resurgence of intravenous heroin use leading to total societal cost exceeding $55 billion. While opiates are effective at treating acute pain, tolerance to the analgesic effects develops quickly, leading to high abuse liability and dependence potential. Consequently, the development of a new, non-pharmacologic intervention to treat pain, such as repetitive transcranial magnetic stimulation (rTMS), which would provide analgesic benefit while also directly remodeling the neural circuitry responsible for cognitive control over opiate craving, would fill an increasingly urgent public health need.
