Exercise may help slow cognitive decline in some people with Parkinson’s disease

And it turns out that this metabolic defense mechanism is triggered in many scenarios, not just concussion.

I became involved in a group of people who were interested in taking ISRIB. We engaged in an effort to synthesize it, and along the way we dredged the internet for any information we could find about other people who had taken ISRIB — the molecule has been known about for a long time. There are a handful of plausible stories, and it appeared that ISRIB would have no effect in one person and be life changing for another, both seemingly healthy. The common pattern was increased intelligence, an insatiable appetite for new and novel information and a marked reduction in the amount of sleep needed to function.

We eventually came into contact with a group of Russians. They had already synthesized it and taken it. They reported the same effects from the accounts we had found. They also reported, surprisingly, the development of a tolerance among those who took it repeatedly. One person had an episode of very realistic hallucinations, dreams that seemed real. Another person gave it to his grandmother who was sick with dementia. She became lucid again but died a day or two later. We speculated that one of the reasons cells turn themselves off is because they are too dysfunctional to operate — so turning them back on brings the benefit of having that signal again in the case of neurons but also revives any dangerous behavior that was being suppressed. We acquired ISRIB from the Russians and the first person to get it didn’t notice an effect although he didn’t take much. At this point I fell out of contact because I was having a medical emergency from experimenting with a totally unrelated compound. It nearly killed me, I spent weeks in the asylum and still have lingering effects. After that my shulgin itch became satisfied permanently.

One interesting thing about cognitive diseases that are metabolically rooted like schizophrenia, dementia, etc is that there are simple ways to coax the cells into metabolizing carbohydrates correctly again, as this article demonstrates. There is also another kind of chemical completely that can be used for energy, beta hydroxy butyrate, totally bypassing the problem. The field of metabolic restoration is the next big thing for sure.

Lucidity before death has been reported before for patients suffering from dementia and other neurological illnesses, so this might have been coincidence. The term is "Terminal Lucidity" if you want to search for it.
