Abnormal auditory evoked potentials in early infancy malnutrition

A B Barnet, I P Weiss, M V Sotillo

    Science (New York, N.Y.)
    |August 4, 1978
    PubMed
    Summary

    Severe malnutrition in infants can cause lasting brain function abnormalities, as shown by abnormal auditory evoked potentials. These brain function indicators improved with nutritional rehabilitation but remained abnormal post-discharge.

    Area of Science:

    • Neuroscience
    • Pediatrics
    • Nutritional Science

    Background:

    • Severe malnutrition, specifically marasmus, significantly impacts infant health and development.
    • Auditory evoked potentials (AEPs) are objective measures of auditory pathway and brainstem function.

    Purpose of the Study:

    • To investigate auditory evoked potentials in infants with severe malnutrition.
    • To assess the impact of nutritional rehabilitation on AEPs in these infants.

    Main Methods:

    • Computer-averaged auditory evoked potentials were recorded in infants hospitalized for severe malnutrition.
    • AEPs were monitored during nutritional treatment and follow-up assessments.

    Main Results:

    • Infants with severe malnutrition exhibited abnormal auditory evoked potentials.

  • AEPs showed improvement correlating with somatic growth during treatment.
  • Abnormalities persisted at hospital discharge and during outpatient follow-up.

    • Conclusions:

    • Malnutrition-induced AEP abnormalities suggest a potentially long-lasting effect on infant brain function.
    • Continued monitoring and intervention may be necessary for infants recovering from severe malnutrition.
