In recent months, we've been looking at the "Longest Journey": reports on the impact of Alzheimer's disease on a growing number of older Americans. This morning, our story comes from Dr. Jon LaPook. It's about a woman whose name you may recognize -- and whose age may surprise you:
B. Smith and her husband, Dan Gasby, do a lot of cooking together at their Hamptons home in Sag Harbor, N.Y.
Cooking stirs up wonderful memories.
"You know, when I was growing up, olive oil went in the hair, it went on the skin, and it still goes on the skin," said Smith. "And it's good for you!"
The restaurateur, designer and decorator has spent a lot of time in kitchens.
LaPook asked, "Do you remember the first dish you made?"
"Uhm, pineapple upside-down cake," Smith said. "I was probably about ten years old."
It was a recipe she learned more than 50 years ago.
B. Smith was a sought-after expert for her knowledge of food and style. Some even thought she was on her way to becoming another Martha Stewart.
But even though she treasures her distant past, the present can be out of reach.
LaPook asked her, "Do you know the date today?" She responded "no."
"Do you know the month?" No.
"How about the year?" No.
"And what does that feel like?"
"It feels like crying," Smith said. "Things like that make me very sad."
Barbara Smith was born in western Pennsylvania, and became one of the first African-American models on the cover of Mademoiselle.
In 1986, she opened a restaurant in New York City, others followed. She hosted a TV program, and put her name on home products. (She and Dan, married 22 years, are also business partners.)
She knew something was wrong, but it would be years before she got a diagnosis: early Alzheimer's.
"I don't know how long it was, but I guess I would say it was maybe two or three years," she said. "And I would sing sad songs: 'You've abandoned me. Love don't live here.'"
Whom did she think was abandoning her? "Well, I would think maybe [Dan] was."
"She was just turnin' me totally off, because of the responses I would get," Gasby said.
For nearly four years, B. was repeating things, or not being responsive to a question. There were misunderstandings. Fact is, she told her doctor how severe it was before she told Dan.
Eventually, she saw a team of experts at Mount Sinai Hospital in New York, including neurologist Dr. Martin Goldstein. Brain scans and tests of her ability to think and remember were abnormal.
"There seems to be a greater degree of atrophy, shrinkage of the hippocampus here," said Dr. Goldstein.
Then, last October, a special scan was done to look for amyloid, a sticky protein that damages nerves. Dr. Goldstein showed LaPook the scans: "It's everywhere," he said.
Of the more than five million Americans with this illness, only about 200,000 are under the age of 65.
LaPook asked Gasby, "When you heard the word Alzheimer's, what went through your head?"
"Shock," he replied. "I mean, she's got the blood pressure of an athlete. You know, she's 64 years old. I mean, she can wear a bikini.
"And you curse God. You get angry. You say, 'Well, how could this happen?'"
