12. Glen Campbell
One of the most recent and well-known celebrities who suffered from Alzheimer’s was Glen Campbell (1936-2017). He announced to the world in 2011 he had Alzheimer’s. He completed his “Goodbye Tour” in Napa, California with a somewhat shaky performance, but a performance none the less. Alzheimer’s cut his life short in 2017.
