Normal Pressure Hydrocephalus in Children — The State of Hypercompensation
According to current knowledge, normal-pressure hydrocephalus (NPH) is characterized by the following biomechanical factors: normal or slightly elevated ICP level and increased resistance to absorption of cerebrospinal fluid (RCSF) (Bering and Sato 1963, Black 1980, Guidetti and Gagliardi 1972). However, little is known about the other biomechanical features of the cerebrospinal system which can also playa significant role in its pathomechanism. In some recent papers, suggestions that increased capability of CSF storage in the ventricular system may be a reason for its progressive enlargement despite normal ICP levels, have been presented (Kosteljanetz 1986).
