[header] How to study intracranial pressure in humans [title] Define intracranial pressure. [step] Intracranial pressure can be high or low. Low intracranial pressure can be caused due to low volume of the cerebrospinal fluid inside the ventricles. 
This can happen due to a leakage of the cerebrospinal fluid from the ventricles through the meningeal membrane. [title] Study the causes of intracranial pressure.
