Cradduck and aging well coach Katherine Ambrose are among the Aging Untold experts sharing ways to keep dignity intact, build cooperation and reset when a talk heats up. "You have to step away. You really do," Cradduck said. "You've got to let yourself calm down."

Ambrose said caregivers can step away by removing themselves or getting help. She listed warning signs, including fantasizing about escaping, getting hot and shaky, or feeling a tense jaw. Those mean a nervous system is at its limit, she said.

Cradduck also wants caregivers to treat communication as behavior. "You've got to figure out what's going on that's causing the frustration," she said. Unspoken expectations make it worse. A person can be cognitively whole and still have no idea what a caregiver wants if nobody has said it.

For anyone caring for someone they love, the advice gets practical fast. Aging expert Amy O'Rourke named words that can escalate a conversation: no, you, always, never, don't and you can't. Tone matters just as much. "It's not just what you say, it's how you say it," Cradduck said. Ambrose put it more bluntly: "If you want to have a better day, have a better tone."

Ambrose says all of it traces back to one root: "All drama and conflict comes from one thing, and that's miscommunication."
