"...his 80-year-old wife, Lorna McCadden, had been diagnosed with early onset Alzheimers disease the previous week..."
How can the diagnoses of ANYTHING at age 80 be considered "early onset"?
That's what I was thinking. My sister died 2 years ago from Alzheimer's at the age of 59 after living for 18 years with it. It's a horrible way to go, but 80 yoa is not early onset.
