Mere surgery will not cure cluster headache--implications for neurostimulation.
This case study concerns a patient with primary chronic cluster headache, who was unresponsive to all treatments and consecutively underwent hypothalamic deep brain stimulation (DBS). DBS had no effect on the cluster attacks, but cured an existing polydipsia as well as restlessness. However, hypothalamic DBS produced a constant, dull headache without concomitant symptoms and a high-frequent tremor. All of these effects were repeated when the stimulation was stopped and than started again. DBS had no effect on a pathological weight gain from 70 kg to 150 kg due to bulimia at night, usually during headache attacks. This case illustrates that cluster headache is, in some patients, only one symptom of a complex hypothalamic syndrome. This case also underlines that the stimulation parameters and anatomical target area for hypothalamic DBS may be too unspecific to do justice to the clinical variety of patients and concomitant symptoms. Hypothalamic DBS is an exquisite and potentially life-saving treatment method in otherwise intractable patients, but needs to be better characterised and should only be considered when other stimulation methods, such as stimulation of the greater occipital nerve, are unsuccessful.
