Answer

Major neurocognitive disorder due to Alzheimer's disease Explanation The patient's gradual memory loss and cognitive decline over six months, along with her alertness during the exam, suggest a neurocognitive disorder rather than delirium. The absence of acute changes points towards Alzheimer's disease as the most likely cause.
