Changes of brain volume and pulse amplitude in the frontal area were determined in 31 children with nephrotic syndrome and 30 in a control group. For the investigations a set for intensive neurological care was used SINN-700 recording brain volume by the method used in hydrocephalometry, and pulse amplitude by photoplethysmography. Brain volume changes were read from the changes of the space between the brain and the skull, and pulse amplitude gave an approximate understanding of the cerebral blood flow. In 77% of children with nephrotic syndrome excessive brain volume was found at the onset of the disease with its reduction with clinical improvement. Excessive pulse amplitude fluctuations were present in 35% of cases, but they were rarely associated with excessive fluctuations of brain volume.
