I'm caring for an alzheimer's patient. We were standing by the sink while I shaved him. He became agitated, said he needed to lie down. Walked a couple of steps and started to fall. I lowered him to the floor -- no chance he banged his head. Face got beet red, and he had a series of heaving gasps for air. I don't think he lost consciousness, although he didn't answer my questions for a few seconds. Entire "attack" was over in perhaps five minutes, then he seemed fine.
