Yes Nicotine has been theoretically shown to slow, “slow” dementia and Alzheimer’s progression for a period of time depending on person. But it is still a highly addictive substance to almost every person on Earth. Also it certainly can be lethal in large or uncontrolled doses, or to someone using a wrong patch dose size that has never used it before.

Interesting to bring up, but I personally would avoid this theoretical approach as there are safer treatments being worked on in the medication/treatment world; and just in removing fluoride and other poisons from food and water.
