Abstract

New daily persistent headache (NDPH) is characterized by new onset headache which remains daily from onset for at least three months. So far only a few studies have been reported in this field. The aim of this study is to report on the phenotype and patient characteristics of NDPH as well as considering the strengths and limitations of the current International Classification of Headache Disorders, 3rd edition, beta version (ICHD-3).

In this retrospective study, we studied 216 patients who were seen at our headache clinic at the National Hospital for Neurology and Neurosurgery (from March 2005 to April 2015) and from Whipps Cross University Hospital (from April 2005 to December 2015). All patients fulfilled ICHD-3 criteria for NDPH. Each patients’ medical file was reviewed to record demographic and outcome parameters.

Overall, median age at onset was 37 (IQR 23) and male: female ratio was 0.56. It was found that 83.8% of this patient population had chronic migraine. Other clinical syndromes included tension type headache (6.9%) and primary stabbing headaches (2.8%).

This is one of the largest cohorts of NDPH to integrate ICHD-3, our findings amalgamate those previously reported and include phenotypes which had been previously been omitted.
