As of September 16, 2026, lecanemab and donanemab are FDA-approved and shown in trials to clear amyloid plaque and slow cognitive decline. The discussion has since moved from the drugs themselves to access: a 12-month wait on a treatment list leaves 25 percent of MCI and 50 percent of mild dementia patients ineligible, and in the U.S. a PET scan or CSF is still required to qualify. Falsely reassuring a patient that memory loss is normal can delay diagnosis by a year and a half or more. The Alzheimer's Association's $100 million push into a possible GLP-1 link remains open.

## Segments

- [Today, Explained](https://boilpoints.com/u/todayexplained), 2026-09-16, 14:32 to 25:41: **Delivers the good news on amyloid and tau drugs**. Delivers the promised good news: lecanemab and donanemab clear amyloid and slow decline, tau drugs and blood tests are coming, and the Alzheimer's Association is putting $100 million into a possible GLP-1 link. Also covers an experimental Chinese brain-drain surgery whose pioneer was arrested on insurance fraud charges. New angle: The Alzheimer's Association is putting $100 million behind research into a possible GLP-1 link to Alzheimer's risk.
- [The Podcast by KevinMD](https://boilpoints.com/u/thepodcastbykevinmd), 2026-10-20, 1:11 to 4:50: **Retells the approved-drugs story with a patient anecdote**. A physician explains why early diagnosis matters now that two treatments can slow Alzheimer's, arguing biomarker testing is required and comparing Alzheimer's to cancer. It retells the approved-drugs story already on the record, adding only a patient anecdote.
- [The Podcast by KevinMD](https://boilpoints.com/u/thepodcastbykevinmd), 2026-10-20, 4:42 to 9:22: **Argues the blood test is the accessible route**. Walks through the three Alzheimer's biomarkers - amyloid PET, CSF from lumbar puncture, and the P-tau-217 blood test - and argues the blood test is the cheap, accessible route to the approved drugs. Adds a waiting-list figure: a year's delay costs eligibility for a quarter of MCI patients and half of mild AD dementia patients. New angle: A 12-month wait on a treatment list leaves 25 percent of MCI and 50 percent of mild AD dementia patients ineligible.
- [The Podcast by KevinMD](https://boilpoints.com/u/thepodcastbykevinmd), 2026-10-20, 9:28 to 12:31: **Finds the gap between the blood test and access**. Walks through the P-tau-217 result bands and finds a gap between the blood test and access: in the U.S. a PET scan or CSF is still required to qualify for the licensed drugs, while the U.K. treats on a high blood result alone. New angle: In the U.S., a PET scan or CSF is still required to qualify for the licensed Alzheimer's drugs.
- [The Podcast by KevinMD](https://boilpoints.com/u/thepodcastbykevinmd), 2026-10-20, 12:31 to 15:14: **Explains the biology behind the narrow window**. MacSweeney walks through the biology behind the narrow window: amyloid builds for about 20 years, triggers microgliosis, and tau then spreads exponentially, so the drugs must come before tau takes off. It explains the mechanism behind a claim already on the record rather than adding a development.
- [The Podcast by KevinMD](https://boilpoints.com/u/thepodcastbykevinmd), 2026-10-20, 15:19 to 20:04: **Lists the early signs that should trigger a test**. MacSweeney lists the early signs that should trigger a biomarker test in primary care and warns that falsely reassuring a patient can delay diagnosis by a year and a half or more, past the treatment window. New angle: Falsely reassuring a patient that memory loss is normal can delay diagnosis by a year and a half or more.
