Sometimes it's hard to believe people's strength in dealing with the changing behavior of a loved one who has Alzheimer's.
I was blown away after hearing about the concept of mistaken attachments -- where the Alzheimer's patient forgets about his or her spouse and falls in love with someone else.
That's exactly what happened to Sandra Day O'Connor, the retired Supreme Court Justice from Arizona who stepped down when her husband was in the early stages of Alzheimer's.
He fell in love with another woman -- much to the Justice's relief -- because his newfound love apparently helped him relax and he appeared happier. You can read more about their story here.
The mistaken attachment phenomenon is relatively common in Alzheimer's patients and about 5 million reportedly have the disease.
