Katie’s grandmother has Alzheimer’s disease. Katie’s grandfather brings her a list of sources he found. Which source is most likely reliable?

A neurobiologist is a relevant expert, and citations let readers check the evidence behind the article. The social media link does not by itself make the source unreliable, though the article’s claims and citations should still be checked. The other sources make an unsupported-sounding connection, may have a financial interest in promoting a treatment, or share personal experiences rather than expert evidence.

AI-written and checked against the verified answer.
