Fortunately, I happened to come across this fantastic documentary on Alzheimer’s disease. It was an HBO special, and after visiting the website, I found they had posted many videos on Alzheimer’s.
I’ve posted the link to the website which has many videos of families experiencing Alzheimer’s disease, families who are participating in studies of Alzheimer’s disease, as well as educational videos with information on what Alzheimer's is and how it occurs.
There are two main videos: The Alzheimer’s Project: Part 1 and Part 2. You can find these two videos (approximately 2 hours in length) under “Momentum in Science”. Be sure to check out the other videos listed under the HBO Special.
