CSF: What Is It and Why Would It Leak?
Q: What is CSF, and what could cause a CSF leak?
A: The brain is supported by cerebral spinal fluid (CSF), which essentially acts as a shock absorber for the brain and the spinal cord. It also delivers nutrients for the central nervous system.
This CSF is encased and enveloped by what we call the meninges, a complex layer of membranes, which protects the central nervous system and also serves as a barrier from the rest of the body. CSF is constantly being reproduced and replaced; it is actually replaced and turned over about three times a day.
In some cases, this system can become disrupted. There can be many causes of the disruption; here are some of the common ones:
- Trauma or injury, such as a fall
- Anatomical conditions, such as a bone spurs or degenerative disc disease
- Past medical procedures, such as a lumbar puncture or epidural anesthesia
