Normal-pressure hydrocephalus

G6_HCNP

normal pressure hydrocephalus: A form of compensated hydrocephalus characterized clinically by a slowly progressive gait disorder (see gait disorders, neurologic), progressive intellectual decline, and urinary incontinence. Spinal fluid pressure tends to be in the high normal range. This condition may result from processes which interfere with the absorption of csf including subarachnoid hemorrhage, chronic meningitis, and other conditions. (From Adams et al., Principles of Neurology, 6th ed, pp631-3)
