[Changes in the nervous system in kidney diseases].

A total of 150 patients with renal pathology (chronic glomerulonephritis, pyelonephritis, urolithiasis, etc.) accompanied by the development of psychoneurological disturbances were examined. In the initial stage of the renal insufficiency the authors observed neurasthenic, radicular, polyneuritic, renovisceral syndromes, in a more remote stage--encephalopathies and disturbances of the brain circulation. The important part in the above-mentioned disturbances is played by azotemia, metabolic acidosis, disturbances of fluid-electrolyte and albumine balance, as well as arterial hypertension.
