Summary

Obtaining informed consent for dementia research is complex. This study argues against mandatory written advance consent, favoring an informal process using subject assent and proxy consent for vulnerable populations.

Area of Science:

  • Bioethics
  • Neuroscience Research Ethics

Background:

  • Informed consent is crucial for ethical dementia research involving human subjects.
  • A key challenge is securing consent from individuals with declining decision-making capacity while protecting this vulnerable group.

Purpose of the Study:

  • To examine the model of obtaining informed consent in advance for dementia research.
  • To contrast advance consent for dementia research with its use in life-sustaining treatment decisions.
  • To propose an alternative to written advance consent for dementia research.

Main Methods:

  • Literature review and ethical analysis.
  • Comparison of advance consent models in clinical treatment and research settings.
  • Argumentative analysis of existing consent practices in dementia research.

Main Results:

  • Written advance consent, while used for life-sustaining treatments, may not be suitable or required for dementia research.
  • An informal advance consent process is proposed as a viable alternative.
  • The proposed model integrates subject assent with proxy consent.

Conclusions:

  • Mandatory written advance consent is not necessary for conducting ethical dementia research.
  • An informal advance consent process, incorporating assent and proxy consent, offers adequate protection for participants.
  • This approach respects autonomy while facilitating research participation for individuals with cognitive impairment.
