I would like to get as much information as I can on manic-depressiveness. I am looking for physiological as well as psychological reactions or symptoms that might be signs of having this disorder. I am specifically interested in if there are any differentiations between males and females, what the average age is of a person having the disorder, and what other medications besides Lithium are used today to treat it. Is there any research to the fact that some people may be treated with a drug and then be taken off of it, or does one have to stay on the drug for the rest of their life?
