Final answer:
Donepezil, used to treat Alzheimer's disease, can cause bradycardia and heart block due to its effect on increasing acetylcholine neurotransmission.
Step-by-step explanation:
The medication used to manage Alzheimer's disease symptoms that can cause bradycardia and even heart block is Donepezil. Donepezil is a cholinesterase inhibitor that works by increasing acetylcholine neurotransmission to help prolong neural function in the brain. However, as it affects cholinergic neurons, it can lead to side effects such as bradycardia and potentially heart block, especially if over-prescribed or in the presence of certain cardiac vulnerabilities. Treatment for bradycardia includes establishing the underlying cause, which may involve addressing metabolic disorders, electrolyte imbalances, and ensuring the appropriate use of medications.
