Which dementia medication is listed as used for dementia?

• A. Memantine
• B. SSRIs
• C. Vitamin K
• D. Donepezil

Answer: (D)

Dementia medications often target neurotransmitter systems to help improve cognitive symptoms. Donepezil is a cholinesterase inhibitor that increases acetylcholine levels in the brain, which are reduced in Alzheimer's disease. This makes donepezil a classic, widely used medication for dementia, helping with memory, thinking, and daily function. Memantine is another dementia medication, an NMDA receptor antagonist, used mainly in moderate to severe stages, but the question highlights donepezil as the listed option. SSRIs are antidepressants and may help with mood or behavioral symptoms but aren’t dementia-directed treatments. Vitamin K has no established role in treating dementia.
