Quantitative Motor Examination in Normal Pressure Hydrocephalus Patients

1.1 Purpose Normal pressure hydrocephalus (NPH) is a neurologic disorder that causes three groups of progressive symptoms that are very disabling: gait and balance problems leading to falls, urinary incontinence, and dementia. This condition is in urgent need of clarification, because while the diagnosis of NPH is very difficult to make with confidence, the gait and postural instability caused by NPH can respond to neurosurgical treatment. The purpose of the present project is to develop methods to improve our ability to diagnose NPH and predict patients' response to neurosurgical treatment.
