Mom With Alzheimer's Surprised Every Time She Learns She'll Be A Grandma

A pregnant woman captured her Alzheimer's-stricken mother clapping with excitement each time she is told she is going to be a grandmother.

Mother-to-be Christine Stone, from Florence, South Carolina, filmed her mother Setsuko Harmon as she told her she was expecting on ten different occasions.

Each time Mrs Harmon, 77, smiles and clasps her hands before asking Christine, 38, when the baby is due.
