Cognitive and emotional effects of renal transplantation

Abstract

Background:Recent studies have shown a high prevalence of depression and cognitive changes in patients with end-stage renal disease (ERSD) and renal transplant recipients. There are few data available on the cognitive and emotional changes in patients undergoing renal transplantation in India.Aim:To evaluate the changes in cognitive profile and depression in renal transplant recipients.Methods:Thirty consecutive patients undergoing renal transplantation were evaluated 1 month before and 3 months after successful renal transplant with Beck Depression Inventory (BDI), Weschler Adult Performance Intelligence Scale (WAPIS), Luria Nebraska Neuropsychological battery (LNNB) and Life satisfaction scale.Results:Our study revealed an 86.7% prevalence of depression in ESRD patients as compared to 56.7% in post renal transplant patients. Analysis of neurocognitive functions on LNNB did not reveal any significant impairment. Furthermore, analysis of the Life satisfaction scale revealed most of the patients scored high satisfaction levels despite the stress of their disease. Results on WAPIS brought out significant improvement in intelligence quotient (IQ) after renal transplantation.Conclusion:Successful renal transplant is associated with improvement in depression, IQ and life satisfaction.
