Dementia does not erase the brain evenly. Some abilities fade early, and others stay remarkably intact, sometimes until very late in the disease.
Fades early: recent memories and conversations, planning and organizing, finding the right words, and the ability to reason in a stressful moment.
Stays much longer: memories from long ago, lifelong habits and skills, music, and the felt sense of being loved or threatened. This is why a person who cannot recall lunch can still sing a song from their youth, fold laundry, or light up at a warm voice.
Here is the single most useful fact in this entire course: your person will forget what you said and forget what you did, but they will not forget how you made them feel. The part of the brain that stores facts fails early. The part that stores feelings lasts far longer. A rushed, tense moment leaves fear behind. A calm, warm one leaves safety, and that feeling makes the next moment easier.
This changes your whole strategy. Stop fighting the abilities that are fading. Build everything on what remains: emotion, connection, old memories, music, and routine. When you lead with the parts of the brain that still work well, you meet your person where they actually are.
