I just spent three days in the other Washington at the national Alzheimer’s Association’s Advocacy Forum. I was one of a thousand volunteers. We were loaded up with all kinds of facts and figures to use in conversations with all 12 of o ur Washington state senators and representatives and their super-smart aides. But that factoid about diagnosis is the one that stuck with me. Really? Really: 55 percent of seniors diagnosed with Alzheimer’s and their caregivers are not told.
