Know your CSF

Know your CSF: Did you know that our bodies produce approximately a pint (500 ml) of CSF daily, continuously replacing CSF as it is absorbed? 

Under normal conditions there is a delicate balance between the rate at which CSF is produced and the rate at which it is absorbed. Hydrocephalus occurs when this balance is disrupted and the rate of absorption is less than the rate of production.
