title: Post-infectious new daily persistent headache may  respond to intravenous methylprednisolone.
abstract: New daily persistent headache (NDPH) is a subtype of chronic daily headache (CDH) that starts acutely and continues as a daily headache from the onset.It is considered as one of the most treatment refractory of all headache syndromes. The pathophysiology is largely unknown. Viral infections, extracranial surgery, and stressful life events are considered as triggers for the onset of NDPH. A few patients may have the onset of their symptoms during an infection. Here we report nine patients with NDPH like headache. All of them had a history suggestive of extracranial infections a few weeks prior to the onset of headache. All patients received intravenous methylprednisolone (IV MPS) for 5 days. Intravenous MPS was followed by Oral steroids for 2-3 weeks in six patients.The relief of headache started between the second and fifth days of infusion in all patients. The steady improvement in headache continued and seven patients experienced almost complete improvement within 2 weeks. Two other patients showed complete improvement between 6 and 8 weeks after initiation of IV MPS therapy. We conclude that NDPH-like headache may occur as a post infectious process following a recent infection. We also speculate on the possible mechanisms of headache in our patients.
