History of lesioning for pain
1Toronto Western Hospital, Toronto, Ont., Canada.
Abstract:
The history of open and subsequently stereotactic brain lesions for the relief of pain is traced. Important steps included recognition of the importance of the non-specific pain pathways and the differential effects of lesioning on nociceptive pain and on different elements of neuropathic pain. Although the advent of morphine infusion and deep brain stimulation has greatly eroded the number of destructive lesions made, new technical and conceptual advances must be carefully evaluated.
Insights
The history of brain lesioning for pain relief is traced, highlighting key discoveries about pain pathways. While newer treatments reduce lesioning, advances require careful evaluation.
Area of Science:
- Neurosurgery
- Pain Management
- Neurology
Background:

- Evolution of understanding non-specific pain pathways.
Observation:
- Differential effects of lesioning on nociceptive versus neuropathic pain elements.
- The advent of morphine infusion and deep brain stimulation.
Findings:
- Key historical steps in lesioning for pain.
- Recognition of distinct pain pathway roles.
Implications:
- Destructive lesioning is less common due to advanced therapies.
