A report from the Cleveland Clinic and Case Western Reserve describes 22 patients with new daily persistent headaches (NDPH) who were treated with Botox injections.
NDPH is a condition in which the headache begins suddenly without an obvious trigger and persists continuously without a break. Because NDPH is relatively uncommon, there have been no large studies of this condition. Patients with NDPH usually do not exhibit symptoms of migraine, such as throbbing pain, nausea, sensitivity to light, noise or physical activity. Because of its sudden onset, we suspect that these headaches may be the result of a viral or another type of infection. There are no treatments that consistently relieve these headaches, but we usually try all of the drugs and approaches we use in migraines.
A group of doctors from Cleveland, Ohio discovered that while Botox seems to help, only 32% of patients with NDPH showed improvement, confirming the refractory nature of this type of headaches. Twenty one of the 22 patients underwent more than one treatment with Botox and most were given a standard migraine treatment protocol with 155 units injected into 31 sites. The improvement was modest but it did result in headache-free days, which were not observed prior to this treatment. The disability improved slightly and when the improvement did occur, it lasted about 8 weeks. Some of our chronic migraine patients also require Botox injections every 8 to 10 weeks, instead of the usual 12. Considering that we do not have any better treatments, Botox should be offered to patients with NDPH.
