Low brain pressure, often leading to low-pressure headaches, primarily results from a reduction in cerebrospinal fluid (CSF) surrounding the brain. This fluid acts as a cushion, maintaining proper pressure within the skull.
Primary Causes of Reduced Cerebrospinal Fluid:
| Cause | Description |
|---|---|
| Spinal Tap (Lumbar Puncture) | Removal of cerebrospinal fluid during a medical procedure, such as a spinal tap, can directly lower the fluid pressure around the brain. |
| CSF Leak Due to Meningeal Issues | Cerebrospinal fluid may leak out due to cysts or tears in the meninges. The meninges are layers of tissue that cover the spinal cord and brain. |
How Loss of CSF Lowers Brain Pressure:
Loss of CSF reduces the overall fluid volume within the skull. Because this fluid provides a protective cushion and maintains pressure, a decrease in CSF results in a direct reduction of pressure around the brain.
Symptoms & Solutions
Low-pressure headaches often worsen when sitting or standing and improve when lying down. If you suspect you have low brain pressure due to a spinal tap or possible leak, consult with a medical professional for accurate diagnosis and treatment options.
