“She’s lying to me.”
It’s one of the most common and heartbreaking things families say when caring for someone with dementia.
But here’s what I want you to understand:
In dementia care, “truth” can be a very tricky concept.
Often, what sounds like lying is not intentional at all. The brain may no longer be processing or storing information correctly. A loved one may forget what was said, remember events differently, or become embarrassed and try to fill in the gaps.
This can happen in Alzheimer’s disease, vascular dementia, frontotemporal dementia (FTD), and other forms of cognitive decline.
And if we challenge or correct them too forcefully? We often meet resistance, frustration, or fear.
The question becomes not “Are they telling the truth?” But rather… “What is their brain able to understand right now?”
This is just one of the many difficult and deeply human topics I explore in my book:
Living in the Moment: A Guide to Overcoming Challenges and Finding Moments of Joy in Alzheimer’s Disease and Other Dementias.
If you’re caring for a loved one and trying to make sense of behaviors that leave you confused or overwhelmed, this book was written for you.
