Low cranial pressure syndrome is a group of syndromes that occur when cerebrospinal fluid pressure is less than 60 mmH₂O in the lateral position. Low cranial pressure syndrome is usually caused by large amounts of cerebrospinal fluid leakage, cerebral vasospasm, and a variety of reasons for decreased production or excessive leakage of cerebrospinal fluid. It is often characterized by symptoms such as position-altering headache, tinnitus, nausea, vomiting, dizziness, neck pain, and in a few patients, hearing changes, photophobia, blurred vision, unsteady gait, convulsions, and decreased level of consciousness. The treatment of low cranial pressure syndrome is usually conservative, mainly general treatment and medication. If the patient still has severe headache symptoms after two weeks of conservative treatment, surgical treatment, such as epidural repair, can be performed. If the patient has the above symptoms, it is recommended to go to a professional hospital in a timely manner, and under the guidance of the doctor to carry out relevant medical examinations, such as cerebrospinal fluid examination, MRI examination, etc., to clarify the cause of the disease and then targeted treatment.
