Reversible long-standing severe disability in idiopathic normal pressure hydrocephalus

Idiopathic normal pressure hydrocephalus (iNPH) presents with the triad of impaired gait, impaired cognition, and urinary incontinence, with enlarged ventricles and normal CSF pressure.1 Reports of CSF shunting and outcome after prolonged severe disability are few. We report a patient who responded dramatically to shunting despite severe motor and cognitive impairment and incontinence for more than a year.
