#leakweek is a week spent raising awareness for Spinal CSF Leak.
Cerebrospinal fluid (CSF) is a special fluid that bathes and supports the brain and spinal cord. When the tough layer called the dura mater (often abbreviated as dura) that holds this special fluid in around the brain and spinal cord has a hole or tear, this results in fluid leak through the defect. Spinal cerebrospinal fluid (CSF) leak is an important and under-diagnosed cause of disabling daily headache that is curable. (spinalcsfleak.org)
