    Tylenol/ diphenhydramine?
    An_267546 posted:
    My husband has been on a regular program of diphenhydramine for years, taking many a day due to allergies and allergy-related skin outbreaks. We both take Tylenol PM on a regular basis at night to help with insomina. His brother has been diagnosed with dementia after an initial misdiagnosis of Alzheimers Disease at only 62. I am seeing on-line concerns about use of both of these meds contributing to dementia and/ or Alzheimers Disease. Are there any real concerns here, or are these internet rumors? Thank you for your help!

    This article explains a little bit about the online concerns you are referring to:

    The study in question showed an association between certain drugs (some for allergies and sleeping problems) and an increased risk of dementia, but it cannot prove that they do cause it. The above article has a link in it that outlines all of the drugs the researchers studied.

    The best thing to do would be to share your concerns with your primary physician. As the article states, many different lifestyle factors could explain the link found in the study, and it is important to weigh all of these and speak with your doctor about the pros and cons of either continuing or stopping your medication before making any changes.
