I heard that sleep deprivation can damage the brain. Is this true? If so, in what ways? Can these damages be reversed or are they permanent?
the answer is absolutely YES. It can cause psychological disorders. Recent studies are backing this up. It can cause scary personality changes. After a day or so of no sleep, you are more relaxed about things you used to worry about. But as the days without any sleep or only light broken insufficient sleep go on, you get way too relaxed. you lose your morals. I noticed this while watching a movie that normally would seriously offend me and I would shut it off; after days without sleep, it had no effect on me at all. You don't have any emotions any more. Your voice becomes monotone permanently. You get very paranoid. Your iq lowers. Your body starts to age rapidly. You can't make decisions. You perceive things in a crazy way. Little noises get very loud- like clocks, etc. It increases your dopamine- sleep deprivation- when you stay up for an extreme amount of time- which causes symptoms of/or schitzophrenia. Severe sleep deprivation has very negative affects on your creativity, emotions, personality, overall mental health. I believe they are permanent. It can turn you into a totally different and awful person.
