Cerebrospinal Fluid (CSF) Leak

A cerebrospinal fluid (CSF) leak occurs when the protective fluid surrounding the brain and spinal cord escapes through a tear or hole in the membranes, often due to injury or surgery. This fluid helps cushion the brain and spinal cord, maintaining pressure and providing nutrients. When it leaks, symptoms can include headaches, dizziness, clear nasal drainage, or a feeling of pressure. Treatment typically involves bed rest, medication, or sometimes surgical repair to seal the leak. Prompt diagnosis and management are important to prevent complications such as infections or persistent symptoms.
