1. A method of treating normal pressure hydrocephalus in a patient in need thereof, the method comprising:
placing the patient in a hyperbaric chamber under conditions effective to increase an intraparenchymal venous pressure of the patient from a sub-normally low value to a normal value or to a value higher than normal, and
venting cerebrospinal fluid (CSF) to an area with pressure lower than the hyperbaric chamber effective to control a CSF pressure in the patient to produce a pressure gradient having the intraparenchymal venous pressure above the CSF pressure.
