[Features of the cognitive activity of end-stage chronic renal failure patients]

Under examination there were 27 patients with chronic renal insufficiency at various stages of hemodialysis treatment. The results obtained point to an impairment of the cognitive activity that manifested in exhaustability, apathy, working capacity fluctuations and memory deterioration due to a greater retroactive inhibition. An impairment of the operational aspect of the cognitive activity manifested in a lowering of the level of generalization and appearance (in cases of difficulties) of morbid philosophizing of the "operational weakness compensation" type. The disturbance of the motivation component of the psychic activity manifested in both distortion of the generalization processes and an inadequate position of the patient during the examination. It is concluded that the disturbances of the cognitive activity observed in the patients with chronic renal insufficiency should be considered in indissoluble connection with their personality changes.
