Triggers May Guide Treatment of New Daily Persistent Headache

Triggers Suggest Treatments

Goadsby proposed in 2011 that new daily persistent headache is a syndrome rather than a single disorder. “I’m completely in agreement,” said Dr. Rozen. “However, I do believe that individuals who have the same triggering event have the same pathogenesis.” Identifying the triggering event and understanding the temporal profile of the first headache can enable the choice of appropriate therapy, he added.

A patient whose persistent headache begins with a thunderclap onset likely has a prolonged cerebral artery vasospasm. Dr. Rozen treated a patient whose initial headache was a thunderclap; imaging ultimately revealed that she had a vasospasm. Her headache responded to nimodipine within days. Nimodipine generally provides relief within three to five days, said Dr. Rozen. If it worsens the headache, then the patient does not have vasospasm, he added.

Many patients with new daily persistent headache have a physical presentation that suggests Marfan syndrome. This observation led Dr. Rozen to hypothesize that cervical hypermobility is a risk factor for new daily persistent headache. Hypermobile patients may put significant stress on the C1, C2, and C3 joints, which are “where the trigeminal–cervical complex comes together,” said Dr. Rozen. A long plane ride or appointment with the dentist could trigger new daily persistent headache. Treatment with onabotulinumtoxinA often helps these patients. High cervical blocks also can bring relief, said Dr. Rozen.

He and his colleagues recently identified a new subset of patients with new daily persistent headache. They were older female patients with a mean age of 57 who suddenly developed the disorder. Most of them reported that the pain was worst before they got out of bed in the morning. Within seconds of assuming the Trendelenburg position, these patients had intensified pain and nausea, suggesting CSF hypertension. The patients all responded to acetazolamide or spironolactone, which lowered CSF pressure. “I think these individuals developed cerebral vein insufficiency because of estrogen withdrawal based on their age. Plus, the majority were overweight, which can also raise baseline CSF pressure.”

Examination Should Incorporate Imaging

All patients with new daily persistent headache should undergo imaging, including a brain MRI with and without gadolinium, plus an MR venogram, which can identify CSF leaks and a cerebral vein thrombosis, which are leading secondary causes of the disorder. Neurologists could examine patients’ viral titers in addition if the history suggests a post infectious trigger. A lumbar puncture and measurement of opening CSF pressure are appropriate for patients who have not responded to medication.

Evidence From the Literature

The literature possibly supports the efficacy of several treatments in new daily persistent headache, but includes no placebo-controlled trials for them. Dr. Rozen found doxycycline to be helpful for several patients with elevated CSF tumor necrosis factor alpha.

Marmura and colleagues found that mexiletine reduced the severity of pain in patients with refractory new daily persistent headache. The treatment did not reduce headache frequency, however, and side effects were common.

In a retrospective study, Prakash et al followed 63 patients with new daily persistent headache for five years. They found that patients who received IV methyl prednisolone and sodium valproate had a better response than patients who received other therapies. They called for prospective and controlled studies to confirm this observation.

In general, aggressive initial therapy is warranted, “especially if you meet an individual within one year of headache onset,” said Dr. Rozen. The likelihood of response to therapy appears to decline with the duration of the headache. “Infusion therapy or inpatient therapy with IV medications, even with standard migraine protocols, may help break the cycle,” Dr. Rozen concluded.
