Communication and informed consent in clinical geriatrics.

R M Ratzan

    International Journal of Aging & Human Development
    |January 1, 1986
    PubMed
    Summary

    Obtaining informed consent from elderly individuals with Alzheimer's disease requires overcoming communication barriers. Addressing sensory impairments and simplifying language are crucial for effective communication and valid consent.

    Area of Science:

    • Gerontology
    • Neurology
    • Bioethics

    Background:

    • Effective communication is essential for obtaining informed consent, particularly from elderly individuals.
    • Elderly populations, especially those with senile dementia of the Alzheimer's type (SDAT), face unique communication challenges.
    • Sensory impairments and cognitive decline can significantly impede understanding and participation in research.

    Purpose of the Study:

    • To identify and discuss perceptual and communication impediments in obtaining informed consent from elderly individuals with SDAT.
    • To propose strategies for overcoming these barriers to ensure effective communication and valid consent.

    Main Methods:

    • Review of common auditory and visual constraints affecting communication in the elderly.
    • Analysis of speech, language, and vocabulary-related challenges.
    • Discussion of specific conditions like presbycusis, presbyopia, cataracts, and glaucoma.

    Main Results:

    • Auditory impairments (presbycusis) and visual deficits (presbyopia, cataracts, glaucoma) hinder information sharing.
    • Speech and language impediments, alongside the use of complex medical jargon ('medicalese'), create significant misunderstandings.
    • These barriers can make informed consent processes difficult or impossible without targeted interventions.

    Conclusions:

    • Overcoming sensory, speech, and language barriers is paramount for ethical informed consent in elderly populations with SDAT.
    • Researchers must adapt communication strategies to address individual needs and ensure comprehension.
    • Proactive measures to simplify language and accommodate sensory deficits are vital for ethical research participation.
