Cluster Headache and Deep Brain Stimulation: How’s it going?
It’s been over 15 years (!) since I first wrote about the benefits of deep brain stimulation for cluster headache. It wasn’t a brand-new treatment at that time. However since cluster is fairly rare, it takes a lot longer to collect useful information.
A recent publication in BMC Neurology had a review of studies of DBS, both older and newer. And their findings were positive.
You can read the report for yourself (Exploring the potential of deep brain stimulation in managing cluster headache: a systematic review), but here are some important points:
- Not every patient benefited. This is important to say from the start. One of the current and future goals of researchers is to understand why DBS is helpful for some patients and not for others, so that no one has surgery that won’t really help.
- That being said, many patients did benefit significantly. The study notes: “Patients who responded positively to DBS often experienced long-term benefits, with sustained reductions in CH symptoms even after several months to years of follow-up. Quality of life measures consistently showed improvements among responders, suggesting that DBS not only reduces pain but also enhances overall well-being.”
- Adverse effects were usually temporary and not serious. A common one was double vision (diplopia), but again it was usually only a temporary issue, compared to the long-lasting effects benefits of the treatment.
- As mentioned above, “overall well-being” was improved. One notable reason for this was that DBS sometimes seems to cut down on nighttime cluster attacks, improving sleep. That’s a huge benefit.
Research will continue, but in answer to the question “how’s it going?” – it’s going well. Deep brain stimulation is still beneficial to many cluster headache patients.
