Subtitled in English. This 47 year-old woman required emergency admission after a psychotic episode where she was fleeing imaginary attackers: "the Gauls"

The character and content of a delirium or psychosis can help determine it's etiology (although of course not specific enough to be diagnostic on it's own). In this alcoholic, the psychosis possesses a story like quality, albeit with a lack of continuity. Cause and effect, before and after, are loose concepts.
