Final answer:
Cholinesterase inhibitors slow the progression of Alzheimer's disease by enhancing cholinergic neurotransmission, helping to maintain neural function. Middle-stage Alzheimer's often involves disruptive memory loss and confusion.
Step-by-step explanation:
The class of medication that slows the progression of Alzheimer's disease is Cholinesterase inhibitors. These drugs, such as Aricept, inhibit the enzyme that breaks down the neurotransmitter acetylcholine, thereby enhancing cholinergic neurotransmission. This can help maintain neural function and potentially slow the progression of symptoms in patients with Alzheimer's disease. A common symptom seen in the middle stage of Alzheimer's disease is disruptive memory loss, along with confusion about time or place, difficulty planning or executing tasks, and changes in personality.
