Final answer:
Alzheimer's disease medications increase the activity of acetylcholine by preventing its breakdown and improving neurotransmitter levels, which may help in managing symptoms of the disease.
Step-by-step explanation:
Medications prescribed to reduce the symptoms of Alzheimer's disease boost acetylcholine activity. These medications, such as donepezil, rivastigmine, and galantamine, are known as cholinesterase inhibitors. They work by preventing the breakdown of acetylcholine, thereby enhancing cholinergic neurotransmission. This increase in neurotransmitter levels can potentially improve neuron communication and help maintain cognitive functions affected by Alzheimer's disease.
