Occipital neurostimulation in primary headaches: update

Area of Science:

• Neurology
• Neurosurgery
• Pain Medicine

Background:

• Chronic headache disorders, including migraine and cluster headache, often prove refractory to standard medical treatments.
• Patients may experience dissatisfaction or intolerance to medication side effects, necessitating alternative therapeutic strategies.
• Migraine is increasingly recognized as a chronic, potentially progressive condition warranting more aggressive management in refractory cases.

Purpose of the Study:

• To explore the potential of device-based therapies for drug-refractory chronic headache disorders.
• To evaluate the application and experience with peripheral occipital neurostimulation (ONS) in patients with chronic cluster headache and chronic migraine.
• To highlight ONS as a less invasive therapeutic opportunity for affecting brain function in difficult-to-treat headache populations.

Main Methods:

• Prospective evaluation of peripheral occipital neurostimulation (ONS).
• Focus on patients with drug-refractory chronic cluster headache and chronic migraine.
• Review of existing trials and case reports on ONS for various headache and craniofacial pain disorders.

Main Results:

• Peripheral occipital neurostimulation (ONS) has demonstrated benefits in diverse headache and craniofacial pain conditions.
• Chronic primary headache disorders have been the most extensively studied application for ONS.
• The study comments on the authors' specific experience applying ONS in challenging patient cohorts.

Conclusions:

• Device-based therapies like ONS represent a significant therapeutic opportunity for intractable headache disorders.
• Peripheral occipital neurostimulation is a viable, less invasive approach for managing drug-refractory chronic migraine and cluster headache.
• Further investigation and application of ONS are warranted for patients unresponsive to conventional treatments.
