Cerebrospinal fluid pressure refers to the physiological pressure exerted by the clear, colorless fluid found within the ventricles of the brain and the subarachnoid space surrounding the brain and spinal cord. This fluid, known as cerebrospinal fluid (CSF), serves to protect the brain and spinal cord by providing cushioning and support.
The pressure of cerebrospinal fluid is essential for maintaining proper brain function and ensuring adequate blood supply to the brain. It is typically measured in millimeters of mercury (mmHg) using an invasive procedure known as lumbar puncture or spinal tap.
Normal CSF pressure ranges are around 5-15 mmHg when measured in the lying position. Abnormal or elevated CSF pressure, also known as intracranial hypertension, can have detrimental effects on brain function and can be indicative of underlying medical conditions, such as brain tumors, hydrocephalus, or certain infections.
Pathological conditions resulting in increased cerebrospinal fluid pressure may lead to symptoms like headaches, nausea, vomiting, visual disturbances, and in severe cases, can cause brain herniation.
Measuring cerebrospinal fluid pressure is an important diagnostic tool used by healthcare professionals to assess the function of the central nervous system and to aid in the diagnosis of various neurological disorders. Treatment for elevated CSF pressure may involve medical management, interventions to reduce fluid production or improve drainage, or surgical procedures, depending on the underlying cause.
