The evaluation of cerebral atrophy in renal dialysis patients by computerized tomography.

Thirty nine patients undergoing chronic hemodialysis, were submitted to brain computerized tomography in order to investigate the probable existence of brain atrophy. Evaluation was done by measuring the size of brain ventricles by means of a planimeter. An enlargement of the ventricles ranging from 1.43 to 3.13 times the normal was found in all patients. No relation was observed between the degree of the ventricular enlargement and the EEG findings, the clinical neurological picture and the duration of hemodialysis.
