Final answer:
The patient with amnesia may have had an issue with the episodic memory area of their brain. Medication administration would be based on the underlying cause, which has not yet been clarified.
Step-by-step explanation:
The patient in the question experienced an episode of amnesia and bewilderment which resulted in a temporary inability to form new episodic memories. Upon ruling out a cerebrovascular accident (CVA) or stroke, it is important to consider other causes of acute confusion and memory loss. The provided scenarios suggest that regions of the brain typically associated with memory and learning, such as the hippocampus, may be affected by antibodies or other pathological processes. Memory loss that spares procedural memory but impairs the ability to recall specific events or facts usually indicates a problem with the establishment of new episodic or semantic memories. Administering medication would depend on the underlying diagnosis, which could range from transient ischemic attacks (TIA) to neurological conditions such as encephalitis or possibly a malignancy such as Hodgkin's lymphoma that affects the nervous system.
