Some symptoms arrive with names and checklists. Others you only learn by living them. For me, one of those has been a persistent, watery runny nose—present for years, yet rarely mentioned in discussions of Lewy body dementia. When paired with unpredictable night sweating, a pattern begins to emerge: not random nuisances, but signs of an autonomic system that no longer regulates quietly in the background. Sometimes the body is speaking clearly. It is the categories that are still catching up.
