Hydrocephalus can be caused by an overproduction of cerebrospinal fluid, or more frequently by a reduction in the ability to drain the spinal fluid. This reduction in the ability to drain cerebrospinal fluid may be caused by a blockage in the drainage pathway such as a tumor or infection.
Other causes of hydrocephalus include:
Traumatic injury
Diseases such as meningitis, cancer or hemorrhage
Brain surgery and other nervous system infections
Hydrocephalus can be present in babies at birth, though it should be noted that Dr. Ahuja does not accept pediatric patients at this time.
