Deep brain stimulation in headache.

Area of Science:

• Neurology
• Neurosurgery

Background:

• Deep brain stimulation (DBS) of the posterior hypothalamic area was introduced in 2000 for drug-refractory chronic cluster headache (CH).
• This neurosurgical intervention targets a key brain region implicated in headache pathophysiology.

Purpose of the Study:

• To evaluate the efficacy of posterior hypothalamic area deep brain stimulation for intractable short-lasting unilateral headache disorders.
• To assess the long-term outcomes and safety of this neuromodulation technique.

Main Methods:

• Posterior hypothalamic area deep brain stimulation was performed in 79 patients with various intractable short-lasting unilateral headaches.
• Follow-up duration averaged 2.2 years, with efficacy measured by symptom improvement.

Main Results:

• The majority of patients (88.6%) had chronic cluster headache (CH); others had SUNCT, paroxysmal hemicranias, or trigeminal neuralgia.
• Overall, 69.6% of patients achieved at least a 50% improvement in headache severity.
• The treatment appears effective across different forms of trigeminal autonomic cephalalgias.

Conclusions:

• Posterior hypothalamic stimulation shows promise for treating refractory unilateral short-lasting headaches.
• The posterior hypothalamic area may play a role in regulating headache duration.
• Further randomized controlled trials are needed to confirm these findings. Due to invasiveness, it's considered after less-invasive options fail.
