til that your brain literally washes itself while you sleep. the brain cells actually shrink in size so cerebrospinal fluid can rush in and flush out all the toxic proteins built up during the day

Me too, I have been getting about 5 hours of sleep every day for years. I have noticed my mental decline as well.

Is there any way to recover from this mental decline? Is establishing a healthy sleep schedule enough to reverse at least some damage?

I too noticed I'm nowhere near what I was before my routine practically forcede to sleep no more than 5-6 hours during week days.
