Progressive dialysis encephalopathy ("dialysis dementia").

H C Chui, A R Damasio

    Journal of Neurology
    |January 1, 1980
    PubMed
    Summary

    A progressive encephalopathy affects long-term hemodialysis patients, causing severe neurological deficits and death within months. This fatal condition, possibly metabolic, currently lacks effective treatment.

    Area of Science:

    • Nephrology
    • Neurology
    • Metabolic Disorders

    Background:

    • Progressive and fatal encephalopathy is a distinct neurological condition.
    • It has been observed in patients undergoing long-term hemodialysis.

    Purpose of the Study:

    • To analyze the clinical characteristics and outcomes of this specific encephalopathy.
    • To identify potential causes and effective therapies for this condition.

    Main Methods:

    • Retrospective analysis of medical records from sixty affected patients.
    • Review of clinical manifestations, duration of hemodialysis, and clinical course.

    Main Results:

    • Onset occurred after a mean of 2.5 years of hemodialysis.
    • Clinical course to death averaged 6.3 months.
    • Common symptoms include communication (87%), cognition (66%), and movement (93%) disturbances.
    • All cases showed nonspecific electroencephalographic abnormalities.

    Conclusions:

    • The condition is a severe, progressive encephalopathy in long-term hemodialysis patients.
    • It is potentially linked to an unidentified metabolic disorder.
    • Currently, no effective therapeutic interventions are available.
