The evaluation of cerebral atrophy in renal dialysis patients by computerized tomography
Insights
Chronic hemodialysis patients often show brain atrophy, indicated by enlarged brain ventricles. This study found ventricular enlargement in all participants, regardless of EEG, neurological status, or dialysis duration.
Area of Science:
- Nephrology
- Neurology
- Radiology
Background:
- Chronic hemodialysis is a life-sustaining treatment for kidney failure.
- Potential neurological complications associated with chronic hemodialysis require investigation.
- Brain atrophy is a concern in patients with chronic diseases.
Purpose of the Study:
- To investigate the prevalence of brain atrophy in patients undergoing chronic hemodialysis.
- To assess the relationship between ventricular size and clinical/electrophysiological parameters.
Main Methods:
- Brain computerized tomography (CT) was performed on 39 patients undergoing chronic hemodialysis.
- Brain ventricle size was quantitatively evaluated using a planimeter.
- Patients' EEG findings, clinical neurological status, and hemodialysis duration were recorded.
Main Results:
- All 39 patients exhibited enlarged brain ventricles, with enlargement ranging from 1.43 to 3.13 times the normal size.
- No significant correlation was found between the degree of ventricular enlargement and EEG findings.
- No significant correlation was found between ventricular enlargement and the clinical neurological picture or duration of hemodialysis.
Conclusions:
- Chronic hemodialysis patients frequently present with brain atrophy, evidenced by enlarged brain ventricles.
- Ventricular enlargement in this cohort appears independent of EEG, neurological status, and hemodialysis duration.
- Further research is needed to elucidate the mechanisms and clinical implications of brain atrophy in hemodialysis patients.
Abstract:
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.
