Alzheimers could be linked to a common virus (sciencealert.com)
The common cold sore virus, which is often caught in childhood, usually stays in the body for life – quietly dormant in the nerves. Now and then, things like stress, illness or injury can trigger it, bringing on a cold sore in some people.

Methylene Blue Address Vascular-Hypometabolism in Alzheimer's Disease (gethealthspan.com)
Alzheimer’s disease (AD) is often associated with amyloid plaques and neurofibrillary tangles, yet growing evidence supports a vascular-hypometabolism hypothesis in which cerebral hypoperfusion and mitochondrial dysfunction—particularly at the level of cytochrome c oxidase—drive early disease processes.

Review: Evidence expanding that 40Hz gamma stimulation promotes brain health (picower.mit.edu)
A decade after scientists in The Picower Institute for Learning and Memory at MIT first began testing whether sensory stimulation of the brain’s 40Hz “gamma” frequency rhythms could treat Alzheimer’s disease in mice, a growing evidence base supporting the idea that it can improve brain health—in humans as well as animals—has emerged from the work of labs all over the world.

Decades of Research Misconduct Stalled an Alzheimer's Cure (sciencefriday.com)
In December 2021, I fell into one of the biggest and most disturbing stories of my career. A credible whistleblower with strong credentials in dementia research tipped me to a major case of apparent misconduct in his field. He produced convincing evidence that lab studies at the heart of the dominant hypothesis for the cause of Alzheimer’s disease might have been based on bogus data.

Alzheimer's Disease as Type 3 Diabetes (gethealthspan.com)
Over the past several decades, Alzheimer’s disease (AD) has been predominantly explained through the lens of amyloid-beta plaques and neurofibrillary tangles, yet an emerging paradigm shift increasingly recognizes metabolic dysfunction—specifically, insulin resistance—as a key driver of AD.
