Normal pressure hydrocephalus (NPH) is a condition that happens when cerebrospinal fluid builds up inside your skull and presses on your brain. This condition is most likely in people over 65. It’s often treatable and sometimes even reversible.
Normal pressure hydrocephalus is a very rare condition—it occurs in fewer than 3% of adults aged 65 and over. It affects men and women equally; because it typically affects older adults, it may sometimes be confused with other types of dementia.
Normal pressure hydrocephalus (NPH) is a neurological disorder caused by too much fluid pressing on the brain. WebMD explains causes, symptoms, and treatment options.
Hydrocephalus can happen at any age, but it occurs more often among infants and among adults 60 and older. Surgery can restore and maintain healthy cerebrospinal fluid levels in the brain. Therapies can manage symptoms resulting from hydrocephalus.
What causes normal pressure hydrocephalus? NPH occurs if the normal flow of CSF throughout the brain and spinal cord is blocked in some way. This may be due to past injury, bleeding, infection, brain tumor, or surgery on the brain, or the cause is often not known.
Normal pressure hydrocephalus (NPH) refers to a condition of pathologically enlarged ventricular size with normal opening pressures on lumbar puncture.
When normal pressure hydrocephalus is treated with a shunt, it stops the condition from progressing and often alleviates symptoms. This improves the patient's quality of life. The outcome for most children with hydrocephalus is also very good.
The average age of onset is approximately 70 years, and men and women are affected in equal numbers. iNPH is thought to account for roughly 6% of all cases of dementia.
Normal pressure hydrocephalus (NPH): causes problems with walking, bladder control, and difficulties thinking and reasoning. The increase in cerebrospinal fluid in NPH happens slowly enough that the tissues around the ventricles compensate and the fluid pressure inside the head does not increase.
Normal pressure hydrocephalus is characterised by the clinical features of hydrocephalus (i.e., levodopa-unresponsive gait apraxia with or without cognitive impairment or urinary symptoms), but without significantly raised cerebrospinal fluid pressure. Cannot be reliably diagnosed using neuroimag...
