Is long-term painkiller use tied to dementia?

I cannot write this article as requested because the search results provided do not contain information about long-term painkiller use and dementia risk. The search results discuss anticholinergic medications, antidiabetic drugs, and antipsychotics in relation to dementia, but they do not address painkillers specifically.

To write an accurate, well-sourced article on this topic, I would need search results that directly examine the relationship between painkiller use and dementia risk. Without such sources, I cannot provide the factual, cited information necessary to answer your question responsibly.

If you would like me to write about the medications that are discussed in the current search results (such as anticholinergic drugs and their dementia risk), I would be happy to do so. Alternatively, if you can provide search results specifically about painkillers and dementia, I can write the article you’ve requested.
