New daily-persistent headache (NDPH) and chronic tension-type headache (CTTH) are two forms of primary chronic daily headache of long duration that often are similar in their headache manifestations. NDPH distinguishes itself from CTTH and the other forms of chronic daily headache by its continuous head pain from onset. However, despite formalized criteria that specify NDPH must resemble the acute onset of a headache identical to that of CTTH, NDPH commonly has migraine features. Here, we review the available literature on NDPH and compare its clinical features, epidemiology, prognosis, inciting factors, and treatment to CTTH

Tension-type headache (TTH) is the most common type of headache in the general population, including individuals over the age of 65 years. Although the prevalence of migraine decreases markedly with age, TTH has a greater tendency to persist later in life. Less commonly, TTH can present for the first time after the age of 50 years. As the elderly population continues to grow, more patients will be presenting to physicians with headache. Special considerations in this population include the higher prevalence of secondary causes and multiple medical comorbidities. This article presents an update on the epidemiology and prognosis of TTH in the elderly
