[Clinically suspected normal-pressure hydrocephalus diagnosis--current status of diagnosis and therapy].

Since the first description of the disease normal pressure hydrocephalus (NPH), there has been a great progress in the diagnosis of this disease. Taking into account that the age of the population is rising the incidence and social medical importance is increasing. Modern neuroradiological techniques are visualising a ventricular enlargement but a definitive diagnosis cannot be drawn. The intrathecal infusion tests represent a save and valid tool while measuring the cerebrospinal fluid dynamics. Shunting is the only possible therapy in NPH. Complications from shunting are still a great problem and therefore, a definite diagnosis must be gained in order to avoid a shunt induced morbidity and mortality.
