Abstract PDF: Primary stabbing headache (PSH), characterized by sudden, localized stabbing headache pain, is a recognized primary headache disorder with evolving diagnostic criteria. Epidemiological studies show a wide range of prevalence, influenced by various factors. PSH is more common in females, frequently occurring in conjunction with migraine, and can manifest in children. Recent diagnostic criteria have changed the definition of sharp stabbing pain, which is no longer restricted to the first division of the trigeminal nerve. In addition, the criterion of “no accompanying symptoms” has been refined to “no cranial autonomic symptoms” specifically. These changes have increased the sensitivity for capturing PSH. Although it is generally considered benign, stabbing headache can be associated with secondary causes. Clinical red flag signs can be helpful in distinguishing secondary headaches from PSH. A recent prospective study has proposed the monophasic, intermittent, and chronic patterns as subtypes, and this division may be helpful for predicting the prognosis. Pharmacological treatment is typically not required for PSH, although indomethacin and other alternating agents can be used. The treatment should be selected based on individual clinical features and comorbidities. This review aims to highlight the necessity of recognizing the distinctive clinical profile of PSH and of tailoring treatment approaches to patients’ individual needs.
