Core Tip
Core Tip: Idiopathic normal pressure hydrocephalus (iNPH) presents with gait disturbance, dementia, and urinary incontinence. Improvement in these symptoms by tap testing, and imaging studies showing characteristic ventricular enlargement, are important for the diagnosis. iNPH is a dementia that is treatable by shunt surgery. This review describes recent pathophysiology, diagnosis, and treatment in iNPH.
