Normal pressure hydrocephalus

Shunt surgery may reduce symtoms for patients with normal pressure hydrocephalus in about 60-80% of the affected individuals. It has been shown that there is a common comorbidity between normal pressure hydrocephalus and Alzheimer disease. Cerebrovascular disease is another common comorbidity in patients with NPH and if the quantity of cerebrovascular changes is widespread in the brain it may have a negative effect of shunt surgery.
