What Causes Nph

What causes normal pressure hydrocephalus? The cause of excess fluid in the ventricles of the brain may be due to injury, bleeding, infection, brain tumor, or surgery on the brain. However, the cause is often not known. When excess fluid builds up in the ventricles, they enlarge and press against nearby brain tissue.

What are the three causes of hydrocephalus?

Lesions or tumors of the brain or spinal cord. Central nervous system infections, such as bacterial meningitis or mumps. Bleeding in the brain from a stroke or head injury. Other traumatic injury to the brain.

What happens if NPH is left untreated?

The symptoms of NPH usually get worse over time if the condition is left untreated. Patients with untreated, advanced NPH may experience seizures, which can get progressively worse. Dementia and/or bladder control problems usually appear after gait disturbances as the condition progresses.
