There is now a disorder/illness/ disease for everything under the sun.
I think it is a "disease". Alcoholism causes dis- ease in the alcoholic. Dis-ease with emotions, life and what have you.
As for the brain telling us to drink despite evidence that could fill a vault not to..... That is the "mental dis-ease" piping up and wanting to sing you the song of its people. Its a horrible song. No one wants to listen.
