One patient in a severe depressive episode describes each hour feeling as though it drags on endlessly, yet when asked directly she correctly states the date, the day of the week, and her current location. A second patient, acutely unwell following a urinary infection, cannot say what day it is, believes he is still at home rather than in hospital, and is unsure how long he has been unwell. Are both of these best understood as a distortion of the experience of time?
No — only the first patient fits. The phenomenon's own text draws this distinction directly: it differs from temporal disorientation in an acute confusional state, which is a failure to know the actual date or time, rather than a distorted subjective sense of its pace. The first patient's felt sense of time dragging, alongside fully accurate orientation when tested directly, is exactly a distortion of the experience of time. The second patient's genuine failure to know the date, place, and duration of his illness instead describes disorientation, most likely arising from an acute confusional state.
