Glen Campbell Opens Up About His Battle With Alzheimer’s [VIDEO]

Campbell and his wife of nearly 30 years, Kim Woollen, spoke with ABC News in their Malibu home for their first television interview since sharing the news that he had been diagnosed with Alzheimer's.

It's very sad to see Campbell in such a confused state. He trails off several times and even forgets how old he is at one point.

For anyone who has ever had to deal with a loved one suffering from the disease, it's heartbreaking to watch.
