I have heard that a very hardened alcoholic can get alzheimers and never know they were a drunk and don’t feel withdrawals from it. Is this true? If it is then that would mean a certain portion of our brain or body can ignore the withdrawal symptoms. What part of the brain is it, and how come they don’t feel the serotonin release anymore like when they were drinking. Or is it a lot or small amount of serotonin or dopamine? With that said then is the complete opposite true? Can a person trick his or her brain into getting drunk without ever touching a drop of it? Do the same parts of the brain then function like it would a person who get;s “high”. Can try to explain further if any questions.
