The International Classification of Headache Disorders has indicated low cerebrospinal fluid pressure headache since the 1st edition (1988). The 3rd edition was stated that in patients with typical orthostatic headache and no an apparent cause, and after exclusion of postural orthostatic tachycardia syndrome, it is reasonable in clinical practice to provide autologous lumbar epidural blood patch. In 2007, the Guidelines for Cerebrospinal Fluid Leakage 2007, Cerebral Spinal Fluid Leakage Diagnostic Imaging Criteria and Diagnostic Imaging Criteria in 2011, and the Cerebral Spinal Fluid Leakage Clinical Guidelines in 2019 were issued. The item ``how to diagnose and treat headache due to low cerebrospinal fluid pressure'' was taken up in the Clinical Practice Guidelines for Headache 2021. Cerebrospinal fluid hypovolemia and cerebrospinal fluid leak are described in the guidelines as headache due to low cerebrospinal fluid pressure and a clinical condition characterized by orthostatic headache secondary to low cerebrospinal fluid pressure and/or cerebrospinal fluid leak. By defining it as such, a path was shown for advancing diagnosis and treatment.
