Summary
Deep brain stimulation (DBS) can cause new chronic headaches in some patients. These headaches may be linked to changes in serotonin neurotransmission following DBS electrode implantation for pain relief.
Area of Science:
- Neurology
- Neurosurgery
- Pain Management
Background:
- Deep brain stimulation (DBS) is a therapeutic option for chronic pain syndromes.
- Headaches are a potential, yet not fully understood, side effect of neurosurgical interventions.
Purpose of the Study:
- To investigate the incidence and characteristics of headaches developing after deep brain stimulation (DBS) for chronic pain.
- To explore potential mechanisms underlying DBS-associated headaches.
Main Methods:
- Retrospective analysis of 64 patients undergoing DBS for chronic pain.
- Identification of patients developing new-onset chronic headaches post-implantation.
- Review of headache characteristics and prior headache history.
Main Results:
- 15 out of 64 patients (23.4%) developed new chronic headaches after DBS.
- Headaches were distinct from prior headache history in all affected patients.
- Electrode locations included periaqueductal gray, sensory thalamus, and internal capsule.
Conclusions:
- Headache syndromes can emerge as a consequence of deep brain stimulation.
- Disturbance of serotonergic neurotransmission is a potential mechanism for DBS-induced headaches.
- Further research into neurotransmitter pathways is warranted to manage DBS-related side effects.
