What is Normal Pressure Hydrocephalus?
Normal Pressure Hydrocephalus (NPH) is a condition that occurs when cerebrospinal fluid (CSF) accumulates in the brain without a significant increase in pressure. This accumulation may lead to the slow onset and progression of symptoms that may mimic other Neurodegenerative conditions such as Alzheimer’s or Parkinson’s disease.
CSF is produced in the Brain (Ventricles) and surrounds the brain and spinal cord before being reabsorbed into the vascular system. It serves to cushion, protect, provide nutrients to, and remove waste material from the Brain and Spinal Cord. Normally, the CSF is continuously absorbed from the brain to maintain a constant pressure, however it is commonly believed that in NPH, while CSF production seems to function normally, it (CSF) is not being absorbed properly. This problem creates a buildup of fluid in the brain which enlarges the brain’s ventricles (cavities), and puts tension on surrounding brain tissue – without a significant increase in pressure.
There are two types of NPH:
- Idiopathic NPH accounts for about half the cases and occurs without any known cause,
- Secondary NPH is associated with an identifiable cause such as a Head injury, Stroke, Hemorrhage, or infection.
Florida Hospital’s Normal Pressure Hydrocephalus (NPH) Program
At Florida Hospital, our primary goal is to identify those patients that will most likely benefit from the placement of a shunt to treat NPH. A secondary goal is to advance the knowledge base in this condition and contribute to the understanding and treatment of NPH. We continually strive to advance the diagnosis and treatment of NPH, as well as provide caring support for patients, friends, and family members.
