Dementia smells anxiety like a cat smells a dog.
She can survive a loud noise, a door bell. Noisy visitors in the kitchen bring her forward in her living room chair. With a frown on her face she asks “What the hell?” (More about language later.) This is a sudden, acute anxious reaction.
But chronic anxiety that never becomes obvious enough to transition into a feeling is too much continual stimulation. Without knowing why, Dementia becomes angry.
When Dementia begins to vibrate, everyone suffers.
