Although country music legend Glen Campbell is working on an album of re-recorded hits, he struggles with Alzheimer's Disease daily. The singer's daughter, Ashley Campbell, gave an emotional plea for Alzheimer's research at a Senate hearing at Capitol Hill this week; her testimony is a grim reminder that this is a heartbreaking disease.

Campbell's daughter, who sat next to her dad and his wife Kim, began by stating, "I think a person's life is comprised of memories, and that's exactly what this disease takes away from you. Like a memory of my dad taking me fishing in Flagstaff when I was a little girl, or playing banjo with my dad while he plays guitar."

She continued, "Now, when I play banjo with my dad, it's getting harder for him to follow along, and it's getting harder for him to recall my name." Tears began running down her face as she paused to collect herself as she spoke these obviously devastating words to the lawmakers.

The singer's daughter concluded by saying, "It's hard to come to the realization that someday, my dad might look at me, and I will mean absolutely nothing to him." The gravity of Campbell's struggle with Alzheimer's is indeed heartbreaking, and it's clear that it's already made a huge impact on the entire Campbell family.
