Hello @anthonyvw1940 and welcome to Mayo Clinic Connect. I'm so sorry about your LO. I was able to find some information that may be helpful below.

"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 I ask what you've been giving your LO to help with the pain and/or what was initially recommended by your neurologist?
