I have read quite a few people describing the same symptoms that my friend has. A normal person whom has a personality change. Mostly in the evenings, but sometimes during the day, they exhibit symptoms of being drunk. There is slurred speech, loss of words, repeating themselves, an angry personality and there is no memory of this behavior the next day! This disease has to have a name? He has been to multiple doctors and they have found Nothing with the blood work, MRI, Etc... It has been 4 years of this! It is unbearable to watch as this man is smart and a great person. I am convinced it is a disease! The first doctors said it was stress- How can no one know what this is? His wife now says she is married to someone else, his children resent him... PLEASE someone help me!!!! I am desperate to know what this disease is and how we can help him!!!!
