title: Spontaneous improvement in "normal" pressure hydrocephalus.
abstract: A patient is presented with "normal" pressure hydrocephalus including dementia, incontinence, and apraxic gait. He had a normal lumbar CSF pressure, hydrocephalus with lack of air over the convexities on pneumoencephalography, and ventricular filling with prolonged retention on cisternography. He did not receive a shunt and, nevertheless, showed spontaneous improvement in his mental function over the next few years. This cases emphasizes the necessity for a controlled study of shunting for "normal" pressure hydrocephalus.
