[Expert consensus on diagnosis and treatment of spontaneous intracranial hypotension(2024)]

Spontaneous intracranial hypotension is a disease characterized by orthostatic headache caused by spinal cerebrospinal fluid leakage. Patients have to remain bedridden, which significantly affects their quality of life. In severe cases, complications such as subdural hematomas may occur. Clinical practice reveals a high rate of misdiagnosis and insufficient implementation of diagnostic and treatment measures. To improve clinical physicians' understanding of spontaneous intracranial hypotension and to standardize the diagnosis and treatment, the Neurologist Branch of the Chinese Medical Doctor Association and the Headache and Sensory Disorders Committee of the Chinese Research Hospital Association organized experts to develop a total of 30 recommendations on the clinical identification, examination processes, diagnostic criteria, treatment, and follow-up of spontaneous intracranial hypotension based on domestic and international clinical practices and recent literature evidence after extensive discussions.
