I have someone who is very close to me is going through a rough time right now with some type of mental illness .And here is what happen one day she was fine and acting normal the very next day she was all confused could not remember anything and got worse as the days and weeks went on .she is to the point where she is not sleeping and walking around like she is in a zone and very very agitated want even speak and not eating much and also just barley keeping her eyes open.She had a ct scan and no sign of a stroke or anything there was a urine infection and the doctors cleared it up that was a mounth ago and she still is acting very confused and very very agitated and walking around mumbling to her self its like she is in a different world very scary . what could this be and what you think might of happened she is now in a mental facility
