Understanding Dementia
You don't need to become a neurologist. You need about ten minutes of the right picture, because once you see what's actually happening, half the daily battles stop making sense to fight.
What dementia is, and isn't
Dementia isn't one disease; it's an umbrella word for what happens when brain diseases (Alzheimer's is the most common) progressively damage the machinery of memory, language, judgment, and self-control. Two things follow from that word progressively:
- It is physical. Brain cells and their connections are being lost. Nobody can try harder around missing wiring, any more than they could walk off a broken leg.
- It changes over time. What works this season may not work next season. You're not failing when a strategy stops working; the disease moved, and you'll move too.
The sentence that changes everything
Behavior is communication. When words fail, needs don't disappear. They come out as behavior. Pacing might be pain, boredom, or a needed bathroom. Anger might be fear wearing armor. "I want to go home" is usually "I want to feel safe." Every hard moment gets easier when you ask, quietly: what is this behavior trying to tell me?
What's lost, and what remains
The losses get all the attention. What remains is what you'll build on:
- Feelings outlast facts. They may forget your visit by dinnertime. The warmth of it stays into the evening. (The reverse is also true of an argument. This is why losing the battle to win the mood is usually right.)
- Old memories outlast new ones. 1965 may be crystal clear while this morning is gone. Meet them where the memories live.
- Rhythm, music, and habit live in deeper, tougher parts of the brain. A person who can't form a sentence may still sing every verse, fold towels perfectly, or sway to the song from their wedding.
- The need to be useful never leaves. Purpose is care. A job (stirring, sorting, holding the leash) often calms what no words can.
Good days and bad days are real
Abilities genuinely fluctuate: with sleep, infection, stress, time of day. Yesterday she buttoned her coat; today she can't. That's not stubbornness or "not trying." Meet each day where it actually is, and read one more thing into sudden big changes: a fast drop over hours or days is usually illness or medication, not dementia. Call the doctor. (More on this on the emergency page.)
Stop asking "how do I stop this behavior?" and start asking "what need is this behavior expressing?" You'll still have hard days. But you'll stop having the same fight twice a day, because you'll be answering the need instead of the noise.
“Even to your old age, I will be the same, and I will bear you up when you turn gray. I have made you, and I will carry you; I will sustain you and deliver you.”
Isaiah 46:4
