According to the Alzheimer’s Association, normal pressure hydrocephalus (NPH) is “a brain disorder in which excess cerebrospinal fluid accumulates in the brain’s ventricles,” causing dementia and other symptoms.
It is a fairly rare condition, affecting approximately 700,000 people in the United States, most of whom are over the age of 60. Although, many more people may have NPH and go undiagnosed, as its symptoms are similar to other neurological diseases. Let’s get to know the specifics of this disorder by exploring these five facts about NPH—including causes, symptoms and available treatment options.
1. Risk Factors and Causes
As with many medical conditions, the risk of developing NPH increases as a person gets older, particularly after they reach the age of 60. But that isn’t the only risk factor that can increase a person’s likelihood of developing the condition. According to Healthline.com, other factors include cerebrovascular disease, vascular disorders, hypertension, and Alzheimer’s disease.
Unfortunately, the exact cause of NPH is rarely ever known. However, there are certain conditions that may cause it to occur, including a head injury, stroke, meningitis, brain tumor, or surgery on the brain, although WebMD says that it is not clear how they lead to NPH.
