[Methods of evaluation of disorders of the cerebrospinal fluid outflow resistance].

Diagnostic methods for estimating the disturbances of the intracranial fluid resorption process were presented. The following tests are described: constant rate infusion test, boluses, perfusion test, constant pressure infusion test. The methods were compared in the face of the concept of nonlinear outflow resistance--pressure relationship. The author presents his concept of the test for complex examination of outflow resistance--pressure relationship.
