[Multi-stage method for the diagnosis of low-pressure hydrocephalus]

Multistage method of low-pressure hydrocephalus diagnosis, elaborated in our department, is discussed. The method consists of four stages: I Clinical and neuropsychological examinations, standard computerized tomography. II Somatosensory evoked potentials. III Determination of water concentration and distribution in fluid compartments of the brain by utilising new mathematical formula. IV Three-phase complementary test. The application of this method allows to eliminate many false diagnoses and may contribute to lower costs of treatment.
