Final answer:
Patients often do not remember episodes of delirium which is an acute cognitive disturbance, making the statement True.
Step-by-step explanation:
The assertion that patients often do not have recollection of episodes of delirium is True. Delirium is an acute cognitive disturbance that can cause confusion, disorientation, and memory impairment. During delirious episodes, individuals may experience a range of symptoms including disruptions in attention, awareness, and cognition. The fluctuating nature of delirium often leads to difficulties in forming continuous memories, and as a result, once the episode resolves, the patient may have little to no memory of events that occurred while they were delirious. This is different from the concept of false memory syndrome, which involves the recall of false autobiographical memories, often without independent witnesses.
