Started with mild dementia. Could converse like they had all their life, drive a car, go shopping, etc.. Then within 2 or so weeks of having a simple outpatient procedure (maybe with anesthesia) went fast into full blown mania with crying, anxiousness, discomfort, not sleeping for days, became 500% more frail. Within days after the anti-psychotic medication (given about 3 weeks after mania started) symptoms mostly went away and patient was 90% like normal. Now over a year later having mania again but not as severe.
