Even without problems with aspiration, he’d probably succumb to pneumonia or heart failure after months of being bedridden.
What medications should be avoided with Lewy body dementia?
If possible, avoid medications with anticholinergic properties, which can worsen cognition, or dopamine agonists, which can cause hallucinations. First-generation antipsychotic medications, such as haloperidol (Haldol), should not be used to treat Lewy body dementia.
Can Lewy body dementia come on suddenly?

Does Lewy body dementia progress more quickly than Alzheimer’s?

What is end-stage Lewy body dementia?
Cause and Effect of LBD. Lewy bodies are clumps of protein found in the nerve cells of the brain.
