Normal pressure hydrocephalus (NPH) is a form of hydrocephalus without an increase in the intracranial pressure. Hydrocephalus means that the spinal fluid containing ventricles inside the brain are enlarged. This condition presents with symptoms of urinary incontinence, abnormal gait, falls and dementia. About one third of cases are due to head trauma, intracranial bleeding or CNS infections, which lead to impaired cerebral-spinal fluid (CSF) absorption inside the brain. The remainder of the causes is still unknown.
