This story attempts to explain some of the on-going research to understand the increased risk of Alzheimer’s disease seen in people with type II diabetes. Utilization of sugar by the brain appears to be altered in Alzheimer’s disease patients, though whether this is a cause or a result of Alzheimer’s disease is not known. The experts quoted in the story think that this problem with sugar utilization in Alzheimer’s disease may be similar to what happens with type II diabetes. They propose that treatment of early Alzheimer’s disease with drugs currently used to improve sugar uptake in type II diabetics will help. This article does not report on results of such study, only the start of a study.
Several people quoted in this story are either directly or indirectly connected to the company that manufactures the medication under study or are currently funded to test this proposed mechanism associating type II diabetes and Alzheimer’s disease. The story could have included the perspective of some expert(s) less directly vested in this work.
Costs are not mentioned. This article paints a disease mongering picture when it says: “It’s a scary scenario: Alzheimer’s already is expected to skyrocket as the population grays, rising from 4.5 million sufferers today to a staggering 14 million by 2050. If the new theory is right, the nation’s current obesity-fueled epidemic of Type 2 diabetes could worsen that toll.”
None of the side effects or potential harms associated with rosiglitazone (Avandia) was mentioned in the article. And the story doesn’t quantify the benefits obtained in the specific subset of patients that showed improvement.
This drug is currently on the market for diabetes so the story could have at least included information about its current cost for its current approved use.
The story doesn’t quantify the benefits obtained in the specific subset of patients with the genotype that showed improvement.
None of the side effects or potential harms associated with rosiglitazone (Avandia) was mentioned in the article.
The evidence comes from an article published in the journal Pharmacogenomics (though not clearly mentioned in the article). The evidence points toward a possible improvement in the subset of mild to moderate Alzheimer’s patients with a particular apolipoprotein E variant in the group given the highest dose of rosiglitazone. It is a preliminary study and additional clinical studies will be required to confirm the results. While this caveat is presented in the abstract of the study, the news story presents the study results as more definitive than the researchers did.

Several people quoted in this story are either directly (Allen Roses) or indirectly (Sam Gandy) connected to the company that manufactures the medication under study or are currently funded (Yadong Huang, Suzanne Craft) to test this proposed mechanism associating type II diabetes and Alzheimer’s disease. The story could have included the perspective of some expert(s) less directly vested in this work.
The story doesn’t mention any other treatments for Alzheimer’s disease. The article did mention a second drug, Actos, used to treat type II diabetes.
Although a researcher at GlaxoSmithKline, makers of rosiglitazone, is quoted as saying “Don’t use Avandia for Alzheimer’s until that question has been settled,” the article does not make clear that rosiglitazone is not FDA approved for the purpose of treating or delaying onset of Alzheimer’s disease.
Rather than an association between type II diabetes and Alzheimer’s disease being “a provocative new theory” – the contention presented in this article – the clinical relation between these two diseases has been discussed for at least 10 years.
We can’t be sure if the story relied solely or largely on a news release.
Systematic, Criteria-Driven
Take all the issues enmeshed in any cancer screening story and amplify it with the liquid biopsy issue. @AP's @CarlaKJohnson. did a solid job here. https://apnews.com/article/science-business-health-hodgkin-lymphoma-oregon-ca899bb9c4c7f1859d4e9ce16a1cf78d
Come on, NY Times; you must do better than this. Important research doesn’t need hype and the “breaking news” BS doesn’t help readers or patients. https://www.healthnewsreview.org/2022/03/nyt-proclaims-breaking-news/
