Alzheimer's Sleep Loss Reversed Without Removing Brain Plaques
Alzheimer's breakthrough: 2 hrs of sleep restored without clearing brain plaques
University of Kentucky researchers found that microglia, the brain's immune cells, drive Alzheimer's sleep disruption by triggering inflammation in response to amyloid plaques. Temporarily eliminating about 87% of these cells in mice restored over two hours of daily sleep and boosted restorative NREM sleep—without reducing plaques. The team is now exploring drugs like Metformin and Stiripentol to calm overactive microglia rather than remove them.
Basically, we showed that it is not the plaques themselves, or solely dysfunctional neurons, that cause sleep loss but actually microglia.

So does this help alleviate the dementia symptoms? Or do those remain but at least the patients get better sleep?

From what I know about terminal lucidity in alzheimer's patients it seems to me that these plaques act like electrical resistors that increase the impedance for neurotransmission. But chemically of course. So if you push more current through the system, such as when you're dying, you can suddenly access memories that were locked off. Is my understanding correct?

...in mice.
Not knocking the research, cure it already! I just think it should be in the title to avoid false hope.
