Discussion on the unethical practices related to a photoshopped scientific paper on Alzheimer's, the importance of early intervention, challenges in late-stage diagnosis, and the urgent need for a biomarker for early detection. The chapter also explores risk factors for Alzheimer's, including non-modifiable factors like age and genes, as well as modifiable factors such as obesity, hypertension, and type 2 diabetes, and the concept of Alzheimer's as a brain form of diabetes due to insulin resistance.
