Surrogate decision making for genetic testing for Alzheimer disease.

Area of Science:

• Neurology
• Genetics
• Bioethics

Background:

• Commercially available genetic tests aid in Alzheimer disease differential diagnosis.
• Patients with dementia often lack the mental capacity for informed consent regarding genetic testing.

Purpose of the Study:

• To address the legal and ethical considerations surrounding genetic testing decisions for patients with dementia.
• To identify appropriate surrogate decision-makers for genetic testing in Alzheimer disease diagnosis.

Main Methods:

• Review of legal and ethical principles governing medical decision-making for incapacitated patients.
• Analysis of state laws pertaining to surrogate consent and advance directives.
• Consideration of family dynamics and the role of assent in decision-making.

Main Results:

• State law and the patient's prior expressed wishes are paramount in designating a surrogate decision-maker.
• Inclusion of other family members in discussions and seeking their assent to the surrogate's decision is ethically recommended.

Conclusions:

• Establishing a clear legal and ethical framework is essential for genetic testing in dementia patients.
• A collaborative approach involving legal directives, surrogate decision-makers, and family input ensures patient-centered care.
