From what reference did Dungeons and Dragons use to describe ability score loss to zero in wisdom and charisma?

In the internet manual it describes ability score loss to zero as:

 Wisdom 0 means that the character is withdrawn into a deep sleep filled with nightmares, helpless.
 Charisma 0 means that the character is withdrawn into a catatonic, coma-like stupor, helpless.

I’ve felt like this at times and I wonder if there is any basis in reality for these descriptions? Can you guide me to a book or site to where I can learn more on both sides of these subjects on the game side and the psychiatric side?
