BackgroundNew daily persistent headache (NDPH) is a type of chronic daily headache. NDPH can have migrainous (NDPH-CM) or tension-type character (NDPH-CTTH). Recently, NDPH patients have shown to have associated anxiety and depression. We compared anxiety, depressive symptoms, somatization and pain catastrophization among NDPH, healthy controls and patients with chronic low-back pain and between NDPH-CM and NDPH-CTTH.MethodsWe assessed the study population for depressive symptoms by Patient Health Questionnaire-9, anxiety by Generalized Anxiety Disorder Scale - 7, somatoform disorder using DSM IV (TR) criteria and pain catastrophizing by using Pain Catastrophizing Scale.ResultsFifty-five patients each with NDPH (mean age 28.24 ± 12.05 years, 45.5% females) and age/sex matched healthy individuals and patients with chronic low-back pain were enrolled. Among NDPH patients, somatoform disorder was seen in 32.7%, severe anxiety in 65.5%, severe depressive symptoms in 40%, significant pain catastrophization in 85.5%. NDPH patients had significantly higher frequency of all psychiatric co-morbidities as compared to healthy controls and patients with chronic low-back pain. NDPH-CM patients had significantly higher frequency of depression and pain catastrophizing behaviour as compared to NDPH-CTTH.ConclusionAnxiety, depressive symptoms, somatization and pain catastrophizing were significantly more prevalent in NDPH when compared to healthy individuals and patients with chronic low back pain. Such effects should be sought for, as they might contribute to refractoriness to treatment.SignificanceAnxiety, depressive symptoms, somatization and pain catastrophizing were significantly more prevalent in new daily persistent headache when compared to healthy individuals and patients with chronic low back pain. Such effects should be sought for, as they might contribute to refractoriness to treatment.© 2017 European Pain Federation - EFIC®.
