<s>[INST] Hello, I have been noticing many symptoms in my cognitive ability lately, and I am unable to identify the source. I started forgetting a lot, lack of focus, impaired cognitive abitlity. This has been going on for years, but before that, I was on top of my class. So I was just wondering, could this be a physical damage to the brain due to years of sleep deprivation and prolonged exposure to stress? And if it is, is it a permanent damage, or is there anything that I can do about it? I have been working on staying healthy, but I don t notice any difference. [/INST] Hello Dear.
