Purpose Of ReviewThe current article aims to provide an overview of new daily persistent headache (NDPH), with a particular emphasis on its pathophysiology, evaluation, and current treatment options.Recent FindingsNDPH is an uncommon and heterogeneous condition associated with various comorbidities and is of great significance due to its prolonged duration and high severity. Variable causes and clinical aspects of NDPH may reflect differences in its underlying pathophysiological mechanisms, including genetics, environmental triggers, neuroinflammation, and brain changes. When assessing a patient with NDPH, potential triggers, past medical history, and differential diagnosis should be carefully considered. Non-pharmacological interventions aimed to improve diet, sleep patterns, and reduce consumption of caffeine and alcohol are recommended for all patients. Nerve blockade and nerve stimulation seem to be more efficacious in children than adults. Antiviral medications and neuroinflammation-targeting treatments may be helpful, particularly, when an infectious disease or severe inflammation is suspected. NDPH patients with concurrent affective disorders may benefit from treatment with serotonin reuptake inhibitors, serotonin/norepinephrine reuptake inhibitors, or benzodiazepines. Cerebrospinal-fluid-lowering medications may be useful for headaches started with a thunderclap or a Valsalva maneuver. Possible treatments for refractory NDPH include intravenous ketamine or lidocaine, onabotulinumtoxinA, and calcitonin gene-related peptide antibodies. Considering the variety of NDPH, it is critical to properly screen patients for correct diagnosis. Proper identification of potential mimics may enable precise therapy opportunities, yet there is no gold standard treatment for NDPH. Further well-designed studies are needed to elucidate the underlying mechanisms and develop effective treatment strategies for NDPH.© 2024.
