Severe alcoholics often get to a point where they will buy a drink or bottle rather than a meal. Over time they become malnourished, not getting enough of all the necessary vitamins. A deficiency in a certain B vitamin will lead to the permanent destruction of their ability to form new memories. This is called "Korsakov's Syndrome."
Oliver Sacks describes just such a patient in his book The Man Who Mistook His Wife For A Hat in chapter 2: The Lost Mariner. The man couldn't remember anything that happened more than ten minutes previously.
No but like earlier I was talking to someone about one brain connecting to another brain and they said the information wouldn't accumulate it would conflict. I was wondering is there a drug or something that would cause amneisa so that the information wouldn't conflict
Well I was just wondering about amnesia out of curiousity too
but you never answered the original question, so...whatever. at least the hare-brained/spare brained thing was kinda funny insulting too but oh well
Drugs like Vicodin have amnesic properties. They don't cause loss of older memories, but prevent the formation of new memories while you're under the influence of them, so you don't remember anything that happened while you were taking the drug. It doesn't work for everyone though.
