New Daily Persistent Headache

Abstract

Objective: This article describes the clinical features, etiology, differential diagnosis, management, and prognosis of new daily persistent headache.

Latest developments: New daily persistent headache has attracted renewed attention as it may arise in the setting of a COVID-19 infection. Spontaneous intracranial hypotension, particularly from CSF-venous fistulas, remains an important secondary headache disorder to consider before diagnosing new daily persistent headache. Symptomatic treatment for new daily persistent headache may include acute and preventive therapies used for migraine and tension-type headache, such as triptans, oral preventive agents, onabotulinumtoxinA, and agents that target calcitonin gene-related peptide.

Essential points: New daily persistent headache is a daily headache syndrome that starts acutely and can only be diagnosed after 3 months have elapsed and other secondary and primary headache diagnoses have been excluded. The clinical manifestations largely resemble either chronic migraine or chronic tension-type headache. The underlying cause is unknown, but it is plausible that multiple etiologies exist and that it is not a single disease entity. The prognosis is variable but often poor, and the treatment approach is largely extrapolated from the management of chronic migraine and chronic tension-type headache.
