The "Personality Glitch":
Why Dementia Looks Like Bad Behavior (And How to Handle It)
🧠👇
Imagine waking up one day and losing your brain’s "delete" button. Every random impulse, every unfiltered thought, and every raw instinct bypasses your judgment completely and goes straight into action.
This isn't a hypothetical horror movie. It is the daily reality of behavioral variant
Frontotemporal Dementia (bvFTD), often described as a "Personality Glitch."
Unlike Alzheimer’s, FTD doesn’t start with memory loss. It starts by physically shrinking the frontal lobes—the exact region that controls our social filters, empathy, and impulse control.
When a loved one with FTD exhibits inappropriate sexual behavior (like public un******ng or crude remarks), it is deeply jarring.
Our gut reaction is shock, shame, or anger.
But here is the "aha" moment:
They aren't misbehaving; their brain filter is broken. They have lost the biological hardware required to realize what they are doing is wrong.
Arguing or lecturing will not work because the brain cells needed to process that lecture no longer exist.
How caregivers can manage this "glitch":
1️⃣ Stay Neutrally Calm: Treat it like a physical reflex, not a moral choice. A calm, matter-of-fact reaction prevents escalation.
2️⃣ Shift, Don't Shush: Don’t argue. Immediately redirect their attention to something else—a hands-on task, a favorite snack, or a change of scenery.
3️⃣ Adapt Clothes: If public un******ng is an issue, look into adaptive clothing that zips or fastens in the back.
Caregivers, give yourself grace. This is a disease of the brain, not a reflection of the person they chose to be. 💡❤️
