What condition results from interference with the circulation of cerebrospinal fluid?

Obstructive hydrocephalus, commonly called “water on the brain,” results from an imbalance of production, circulation, and reabsorption of cerebrospinal fluid. Since cerebrospinal fluid is being produced continually, once the balance is disrupted the volume of cerebrospinal fluid within the brain will continue to increase. The increased volume of fluid leads to compression and distortion of the brain. Left untreated, the intracranial pressure increases, often causing brain function to deteriorate. In infants, treatment often includes the installation of a shunt to either avoid the site of the blockage or drain the excess cerebrospinal fluid.
