A revival of the claims in an earlier research study that over-the-counter anticholinergic medications (which includes Benadryl and many of the PM versions of acetaminophen and ibuprofen) causes an increased risk of developing dementia is making its way around social media.
As I strongly urge on a continual basis, we must be aware and intelligent about the context of all research and the tendency among humans to extrapolate generalizations and make them absolute truths from very specific research studies, as well as to perpetuate misinformation, disinformation, and out-and-out lies.
We have the responsibility to thoroughly educate ourselves about these diseases and get all the facts – if there actually are any (many of the more outrageous things I’ve seen have little to no factual basis and yet they are the very things that people widely distribute as truth) before believing anything you see and hear (or read).
The more you learn and know about these neurological diseases, the better able you will be able to distinguish between what is true and what is not (there is a lot of garbage and there are a lot of garbage claims out in cyberspace – when we fall for it, 
we, frankly, show our ignorance and unwillingness to do the work required to get any kind of comprehensive and knowledgeable understanding of these diseases).
The facts about this study, its context, and over-the-counter anticholinergic medications are in this clinical report.
Going Gentle Into That Good Night 
Find the truth about what you put in your body. Find the truth about the disease you have. When I read side effects of over the counter or prescription drugs and see the warnings, I do not take them. The internet provides any view you wish to belive, if you get the website that supports what you want to believe. Just like the facts on medication or food we need to know the true facts about each disease we deal with. If you want to learn about dementia, go to the real experts. Very good post.
If only people were knowledgeable instead of gullible and were willing to learn instead of just accepting whatever comes their way as truth without any proof or investigation on their own to confirm or deny what comes at them.
We, as a society, have become the proles that George Orwell described in “1984.” The few of us who seek the truth in every part of our lives, being able to discern between credible and rock-solid sources and those who are not have become more like the Winston Smiths (Orwell’s protagonist in the same novel) and it doesn’t bode well for us in the end (ignored now and destroyed later because we refuse to accept, say, or do anything but what is true, no matter what the cost). Thanks for reading, as always, Liz.
Sticking your head in the sand and ignoring things seems to be what most people do anymore. I have so often heard, “Well, I do not care what you say, I am going with the majority, whether they are right or not.”
Never follow the crowd because you’ll always end up some place that you don’t recognize and you never meant to be. Turning our backs on truth and facts seems to be another affliction of society. We don’t care, and that is the heart of the problem.
