title: Chronic migraine - new treatment options.
abstract: Chronic migraine (CM) is defined as headache occurring more than fifteen days/month for at least three consecutive months, with headache having the clinical features of migraine without aura for at least eight days per month. Recently, new treatment options became available in chronic migraine patients. Topiramate is effective in chronic migraine, in the presence or absence of medication overuse, and/or other migraine prophylaxis. Efficacy of onabotulinumtoxin A as a preventive treatment of chronic migraine has been shown in the PREEMPT studies. Occipital nerve stimulation (ONS) is an invasive treatment for refractory chronic headaches. ONS has encouraging results in refractory chronic migraine patients in commercially funded, multi-centre randomized trials.
