Аннотация
BACKGROUND: Cluster headache (CH) is the most common of the trigeminal autonomic cephalalgias (TAC), presenting with excruciatingly severe, short-lasting, unilateral headache accompanied by cranial autonomic symptoms. Chronic CH occurs in 10-15% of patients. Deep brain stimulation in the posterior hypothalamic region (hDBS) is successful in treating about 60% of patients otherwise refractory to medical treatment.
CASE: A 28-year-old man had hDBS for medically refractory left-sided chronic CH, with a resultant reduction in frequency and severity of his attacks. He developed recurrent paroxysms of sneezing soon after the stimulation was started that have reduced after increasing the pulse width from 60 to 90 µs.
DISCUSSION: Stimulation of the brain in the region of the posterior hypothalamus could produce sneezing from activation of facial nerve parasympathetic or trigeminal afferent pathway activation through the trigeminohypothalamic tract, or through other central mechanisms. DBS in general offers the opportunity to illuminate our understanding of brain function and for CH offers particular opportunities to understand a devastating primary headache syndrome.
