 What is dementia? Is it the same as Alzheimer's? What is vascular dementia, Lewy body, FTD, TBI, and CTE? If someone has memory loss, does that mean they have dementia? Millions of Americans ask these questions every day. I did too, and I learned. My wife, Ginny, developed dementia. I didn't know what to do or what was coming next. I'm Kevin Jamison, volunteer and president of the Dementia Society of America. I'm excited to offer you a free guide to understanding dementia.
