normal-pressure hydrocephalus
normal-pressure occult hydrocephalus dementia, ataxia, and urinary incontinence with hydrocephalus, i.e., with enlarged ventricles associated with inadequacy of the subarachnoid spaces, occurring in middle-aged and older persons. The cerebrospinal and spinal fluid pressures are at the upper end of normal, but with the excess spinal fluid volume, that pressure is actually abnormally high. Called also occult normal-pressure h.
