title: Does NDPH exist? Some clinical considerations.
abstract: The analysis of case series of new daily persistent headache (NDPH) reported so far in the literature and the clinical evaluation of affected patients seen at headache clinics suggest that the current International Classification of Headache Disorders (ICHD-II) diagnostic criteria for NDPH are not adequate. In particular, in several instances headache features are not consistent with those of tension-type headache, as the ICHD-II expects. Before making a diagnosis of primary NDPH, it is imperative to rule out that it may be due to any underlying systemic disease. Just as importantly, the presence of psychiatric comorbidity and the possible role played by stressful life factors in triggering NDPH onset should also be searched for. Probably, it will only be through some future improvement in the classification of headache attributed to psychiatric disorder (chapter 12 of the ICHD-II) on the one hand, and through a careful psychological evaluation of patients currently diagnosed as NDPH sufferers on the other, that we will finally know whether primary NDPH actually exists.
