Genetic testing for early-onset Alzheimer disease

Area of Science:

• Neurology
• Genetics
• Medical Ethics

Background:

• Genetic testing for Alzheimer disease (AD) risk genes is increasingly available for patients with probable AD and at-risk family members.
• The decision to pursue genetic testing presents complex challenges for neurologists and patients.
• Limited preventive and therapeutic options for AD necessitate a cautious approach to genetic testing.

Observation:

• Physicians must evaluate the appropriateness of genetic testing on a case-by-case basis due to varying potential benefits and risks.
• A structured decision-making process is crucial for guiding clinicians.
• Counseling and result disclosure are critical components of the genetic testing pathway.

Findings:

• The article provides a framework to assist clinicians in the genetic testing decision process for Alzheimer disease.
• It emphasizes the importance of individualized assessment, considering patient-specific factors.
• Guidance is offered for effective counseling and disclosure of genetic test results.

Implications:

• This guidance supports neurologists in making informed decisions about Alzheimer disease genetic testing.
• It aims to enhance patient care by addressing the unique challenges of genetic testing in clinical settings.
• Understanding these challenges is vital for the responsible integration of genetic testing into routine neurological practice.
