Idiopathic normal-pressure hydrocephalus (iNPH) is a neurological disorder in which patients experience enlargement of the cerebral ventricles without an increase in cerebrospinal fluid pressure. Typical symptoms include gait disturbances, dementia and urinary cilia problems. The diagnosis is based on clinical symptoms, imaging methods (e.g. MRI) and cerebrospinal fluid examination. The treatment consists in the surgical removal of cerebrospinal fluid through a special drainage system (shunt). Studies show that about 70-90% of patients experience improvement in symptoms, especially walking, after surgery. Risks of treatment include infections, bleeding, or CSF spillage. Early diagnosis is important, as delay in treatment can lead to permanent consequences.
