brain damage from alcohol poisoning
I am wondering about brain damage resulting from isolated heavy drinking nights. I have read that if you drink a ridiculous amount and narrowly escape death you may have irreversibly damaged your brain. I can't find anywhere on the internet information about this that could help me figure out whether I have brain damage from alcohol. The other night I drank a fifth of 70 proof liquor in no more than 4 hours, though I can't be certain about how long it took me because I don't remember anything after I had taken the water level in the bottle down about 4 inches. I weigh 165 pounds. I blacked out quickly and the next thing I knew I was in my bed the next day with a little bit of vomit on my pillow and sheets. I was conscious enough to navigate my driver to my home, which was after I finished off the bottle, and I threw up in the car on the way home. And people said that had a good time with me that night so I don't think I was lying down in the corner unconscious. I have a weak stomach and I have always considered that my safety net from alcohol poisoning. I always thought that I would start throwing up long before alcohol poisoning could even become an issue, since throwing up would make me stop drinking that night. But in my reading, I have learned that drinking hard liquor really quickly can actually dangerously slow down your gag reflexes so you aren't guaranteed to throw up efficiently. I have never been one to drink very often.... I have never had addiction... but sometimes, with the right type of liquor, I just end up drinking it too fast, maybe because I don't give my body enough time to absorb it before drinking more, and my decision making process is a little messed up when I'm drinking liquor, to say the least. The night I just described is an example of one of only a handful of major blackout nights I have had in my life. I'm 23 years old. In fact, the night I just described might even be the closest I have ever come to alcohol poisoning, based on how much I drank and how fast. My hangover wasn't terrible since I slept through much of the next day. I didn't throw up at all after I woke up. I usually throw up when I'm hungover. My concern is not alcoholism, or the sort of brain damage that results from a long drinking history.... my concern is with the type of brain damage that can occur when you drink too much just one time. I have read that when you have a high enough BAL you don't take enough breaths and starve your brain of oxygen.... I don't know if I have done that. I have always seemed to recover fine from my black out nights... certainly no symptoms of any "brain damage." But then again, what would be symptoms of brain damage? All I can find on the internet about this matter is: "alcohol poisoning can cause irreversible brain damage." Nothing more. How exactly does lack of oxygen damage the brain? what part of the brain does it damage? And what would a person who got brain damage be like afterwards? Would they have a different personality? Would they be slower witted? I just really want to know the likelihood of me having a damged brain, even if it's just a little tiny bit of damage. I certainly don't feel like I have a damaged brain, but if you ask me if I have ever had alcohol poisining... I would have to say that yes I probably have.
And I don't plan to ever drink heavily again. I would appreciate any thoughts on how exactly acute alcohol poisoning damages the brain. Thank you.
