SUBCLINICAL RENAL DYSFUNCTION AS AN ULTRASOUND PREDICTOR OF COGNITIVE IMPAIRMENT

Аннотация

Subclinical renal dysfunction is increasingly recognized as a systemic condition associated not only with cardiovascular morbidity but also with cognitive decline. Structural and hemodynamic changes  in  the  kidneys  may  precede  overt  laboratory  abnormalities  and  can  be  detected  using ultrasound and Doppler techniques. Growing evidence suggests a close kidney–brain interaction mediated by shared microvascular pathology. This study reviews the role of renal ultrasound markers as early predictors of cognitive impairment, emphasizing their value in risk stratification before clinical manifestation of chronic kidney disease or dementia.
