[Update on diagnosis and treatment of normotensive hydrocephalus (chronic hydrocephalus of the adult)].
Normal pressure hydrocephalus, or adult chronic hydrocephalus, is a relatively unknown entity. Classically, this disease is characterized by progressive dementia, gait disturbance, and urinary incontinence. Despite an increase in the prevalence of this type of dementia due to longer life expectancy, its diagnosis and treatment remain controversial. Recent studies have reported that the percentage of patients who show clinical improvement after shunting is still low and that the complication rate is excessively high. However, our experience and that of other authors indicates that the percentage of improvement after shunting can be greater than 80% and the complication rate can be low if a strict diagnostic protocol is applied and if the most appropriate valve is selected, based on the hydrodynamic characteristics of the shunt. The aim of this review is to provide an update of the clinical features, diagnosis and treatment of adult chronic hydrocephalus. We also discuss the diagnostic and treatment protocols applied in our centre in patients with suspected adult chronic hydrocephalus.
