[Clinical signs and therapy of intermittent normotensive hydrocephalus (author's transl)].

Ventricular fluid pressure (VFP) has been continuously recorded for several days in a series of 9 patients with Intermittently Normotensive Hydrocephalus. This entity can be diagnosed with a reasonable degree of certainty by this method, due to the occurrence of periodic increases of VFP--mainly of ramp-waves as described in the paper. Thus, the designation Intermittently Normotensive Hydrocephalus appears to be more exact. Therapy by means of CSF-shunting procedures is more successful in cases with clearcut periodic rises in VFP.
