orine Reed had worked at a Portland apparel
company for two years when she noticed
something strange happening. She'd start a
routine task and forget what came next, as
if she had driven into a mental fogbank.
Her primary care doctor chalked up Norine's memory
problems to stress and told her not to worry; we all forget
things as we get older.
But Norine's problem just seemed to grow. Her large,
boisterous family (her son-in-law affectionately calls them "the
loud family") noticed that Norine was telling the same stories
over and over, as often as three times in a single evening.
She started gerting lost, even in heLown neighborhood in Troutdale, Ore. "
Her grown daughter, Christine, remembers when her mother
was driving them to Target just a few blocks away from Norine's
home. "She went to turn left at the light when we were supposed
to turn right," Christine says. "I said, 'Where are you going?' She
said, 'I don't know.' She forgot where we were going. She forgot
where she was."
Norine's memory problems began to take a toll on her 33-year
marriage to Todd, a friendly security system salesman.
"She'd ask me something about my job, then completely forget
what I told her," he says. "I thought she was just not paying
artention to me. That she didn't care."
But it was a routine medical appointment that sounded the
final alarm. On the day of her checkup, Norine arrived at the
clinic to find a sign on the door directing patientS to a new
address. When she found the new location, she told her doctor,
"You moved and didn't tell me!"
"Norine," the doctor said. "We moved a long time ago.
You've been here since then."
The physiciarl referred Norine to neurologist Michael
Mega, M .D., Ph.D ., medical director of Providence Cognitive
www.providence.org/toget her
Assessment Clinic at Providence Brain Institute. After a series
of tests, ranging from pencil-and-paper quizzes to sophisticated
brain scans, Dr. Mega delivered the diagnosis on Feb. 9, 2009.
As orine sat with Todd, Dr. Mega showed them a scan of
a healthy middle-aged brain, then a brain of an 80-year-old.
Norine's brain looked more like the 80-year-old's. Her
hippocampus, the center in the brain where memory is formed,
was shrinking. Norine had rare early onset of Alzheimer's disease,
a degenerative disease that destroys memory, reasoning, thinking
and eventually the body's ability to function . It strikes the vast
majority of its sufferers after age 65, and the average life
expectancy after diagnosis is 10 years.
Norine and Todd were in shock, then in tears.
Norine's thoughtS immediately turned to her grandmother, who
has dementia and requires 24-hour help. "I don't want to live like
that," she told Todd, "where somebody has to take care of me."
Aiming to cure the cause What the Reeds didn't know then is that researchers at Providence
Brain Institute had begun testing a new treatment for people in the
early stages of Alzheimer's disease - a treatment that, if successful,
would reverse some of the disease's devastating symptoms and
delay itS progression.
The research is the latest in a growing understanding of the
condition, which got itS name in 1906 when German neurologist
and psychiatrist Alois Alzheimer identified a progressive,
degenerative brain disease that had no known cause or cure.
Until then, Alzheimer's was lumped in with the broader category
of dementia, and was considered a natural part of aging. "Many people think that dementia and Alzheimer's disease are
equal," Dr. Mega says. "It's not true. There are about 50 different
causes of dementia - Parkinson's disease, stroke, vitamin B-12
deficiency, hypothyroidism, some types of infections. Some are
reversible; some are not." > > >

What distinguishes Alzheimer's disease from other forms of
dementia is the presence of clumps of toxic proteins in the brain,
believed to be the cause of the disease. O ne of these proteins is
the sticky "beta-amyloid which binds together to form plaque
between nerve cells. Another protein creates tangles rather than
plaques. Researchers suspect that both tangles and plaques play
important roles in the formation of Alzheimer's disease.
In the 1980s Alzheimer's research made a giant leap fOlWard
when scientiStS discovered a gene mutation in some families that
causes carriers to produce excessive amounts of the amyloid
protein. Arlasr researchers could isolate that defective gene,
inject it into mice, and study the effects of the beta-amyloid
protein and plaques on a living creature.
As research progressed in human trials, scientists discovered that
aearments to eliminate beta-amyloid protein and plaques didn't
have much effect on people with late-srageAlzheimer's. By then the
damage to the brain had been done and couldn't be reversed. Anti
amyloid treatments might, however, benefit people in the early stages.
Fortunately, better diagnostic testing now allows doctors to detect
Alzheimer's earlier, when the toxic proteins are just beginning to have
an effect. The research trials at Providence Brain Institute are targeted
for people with very early Alzheimer's disease and its precursor,
mild cognitive impairment. Support for this research comes from
Providence St. Vincent Medical Foundation. If successful, these
treatments can be given long before toxic proteins and plaques cause
irreparable damage - a potential breakthrough in treating Alzheimer's.
"If these new agents delay the decline from m ild cognitive
impairment to Alzheimer's disease by merely five years,"
Dr. Mega says, "then the prevalence of Alzheimer's disease
in our society will be cut in half' - .
"1 was losing my best friend" In the weeks afrer her diagnosis, Norine hadn't yet enrolled in a
clinical trial at Providence. She was still reeling from the news,
which hit her husband as hard as it did her.
"I was losing my best friend," Todd says quietly. "It seemed like
the end of the world at that point. She was going to fade away
and forget who I was."
The couple met when they were both 20. Norine worked as a
computer operator at the University of California, Los Angeles.
She was on her way home one night when she decided to Stop by
the Air National G uard base to visit a young man she had a crush
on. Instead, a new guy was working the shift - Todd Reed.
"She acrually laughed at my jokes," he recalls. "I just said, 'H ey, if you have nothing to do, why don't you just stay around and talk?'"
The pair was inseparable from then on. They were engaged a
month later and married within six months.
They had four children, Christine, Mindy, Marthew and Eric.
They built a life together and watched as their own parents and
grandparents aged. Even as Norine's grandmother developed a
non-Alzheimer's dementia, Norine never thought she'd develop
a similar illness, and certainly not at age 51 .
By the time she was diagnosed, Norine's ability to work had
deteriorated to the point that she took a voluntary layoff. Although
she didn't suffer the visual or spatial misperceptions common with
Alzheimer's disease, she stopped driving for fear of gerting lost.
Now she and Todd threw themselves into batding the disease
in whatever way they could. orine bought every vitamin and
supplement that Dr. Mega suggested. She worked on lowering
her stress, which has a damaging effect on the brain. She did
brain teasers to help grow new neural networks to replace those
killed by beta-amyloid protein. And she began taking Aricept, an
Alzheimer's medication that sometimes sharpens mental acuity.
The couple joined an Alzheimer's support group for patients
and their families, but found the experience unnerving.
"It was hard listening to the people who were further along
than I was," Norine says.
"You see your future, and you're heading toward it," Todd adds.
"You can't stop it," Norine says, "It's like a train."

The brain of someone with Alzheimer'S disease has fewer nerve cells, and is clouded by abnormal proteins.
Likewise, twisted fibers found inside the brain's cells (the dark areas inside the cell, pictured lower right) prevent nutrients
In a healthy brain, beta-amyloid protein is broken down and eliminated. In Alzheimer'S disease, protein fragments accumulate to form hard, insoluble plaques that block synapses from firing.

and other important substances from traveling between nerve cells.

"It's normal to be forgetful as we get older," says neurologist Michael Mega, M.D., Ph.D., from the donor-supported Providence Cognitive Assessment Clinic. "The question is, what is abnormal?"
It's a question that comes up when we lose our car keys, or even our car. But the degenerative disease of Alzheimer's encompasses far more than typical memory loss, and symptoms often come much earlier than the diagnosis.
If someone is showing signs of cognitive impairment, this simple test can be a reliable indicator: How many animals can you name in one minute?
"When you score fewer than 15 animals in one minute, that imparts perhaps a 20-fold increased risk of going on to develop Alzheimer's disease," Dr. Mega says. "A normal 75-year-old will name about 18 animals in a minute. Most 40-, 50- and 60-year-olds will name in the mid-20s."
Dr. Mega and the national Alzheimer's Association share some other early warning signs:
• . . . .. Typical: Forgetting names or appointments, but remembering them later Unusual: Forgetting information recently learned; repeatedly asking for the same information; using memory aids such as notes for routine events
Typical: Making a mistake balancing your checkbook or forgetting how to program a VCR Unusual: Having trouble following a familiar recipe or keeping track of monthly bills; getting lost going to a familiar place; forgetting the rules of a favorite game

. .. . . . . Typical: Occasionally feeling tired of family or social obligations; becoming irritable Unusual: Unexplained depression, particularly if you've never had a history of depression; lack of motivation; lax grooming; loss of interest in things you once enjoyed; unexplained anxiety and fearfulness
• • Typical: Forgetting the day of the week but remembering it later Unusual: Losing track of dates, seasons and the passage of time; forgetting where you are or how you got there
Typical: Occasionally losing a pair of glasses or a remote control Unusual: Putting things in unusual places, such as the remote in the refrigerator; an inability to retrace your steps to find what you lost
• • Typical: Sometimes struggling to f ind the right word Unusual: Forgetting the point of a conversation; calling things by the wrong name such as a "hand clock" instead of a watch
A remarkable change Six months afrer diagnosing Norine's condition and stabilizing
her medication, Dr. Mega suggested she enroll in a clinical trial
for an antibody called bapineuzumab (pronounced bap-ah-NEWzu-mab). Bappi, as it's called, is an antibody produced by rabbits
that binds to the beta-amyloid protein and removes it from the
brain. It's in the last phase of testing before possible approval by
the U.S. Food and Drug Administration.
As with many clinical trials, this one has a necessary catch:
Norine wouldn't know whether she was getting the antibody or a
placebo. The blind approach helps determine if a given treatment
is working.
She agreed without hesitation and began receiving infusions
evety 13 weeks. After her first infusion, she didn't notice any
change except for a migraine headache. It was possible that she
had been given an inert substance, the placebo. H er second
infusion seemed about the same at first.
Shortly afrerward, her daughter Christine asked her mother
how many infusions she'd had.
"Two," Norine replied.
The significance of that answer was almost imperceptible, but it
didn't escape Christine. Her mother had remembered the number.
After the third infusion, other positive signs began to emerge.
Norine would start to tell a story and stop herself. "Did I tell you
this?" she'd ask "That's right, I did."
Norine became aware that she wasn't getting lost as often. The
fatigue that had drained her during the months before the diagnosis
and forced her to nap before and afrer work was going away.
Her friends noticed that the shuffling gait she had developed
also was disappearing. By now it was irrefutable: the fog in
Norine's brain was beginning to lift. "I was able to read again," Norine recalls. "Before starting the
trial, it would take me months to even read a skinny paperback
because I couldn't remember what I'd just read." After the third
infusion, "I started realizing that I was able to understand. That's
how I knew I was getting better."
Dr. Mega doesn't know for certain ifNorine is getting the
antibody, but a battery of tests given every three months confirms
that Norine is regaining her cognitive ability.
Nearly two years afrer she began the clinical trial, Norine has
regained many of the abilities she had lost. She no longer relies
on the written reminders that used to guide her through each day.
And afrer some gentle prodding by Todd, she is driving again,
starting with shorr trips to the nearby coffee shop.
She's considering going back to school to get a master's degree
in apparel design, a project that would continue to exercise her
mind. In the meantime, she has taken a temporary job with
another apparel manufacturer.
"There's a possibility that the stress might be too much,"
Norine says of her new job. "lEI start to feel like it's too much,
I won't continue."
"We're taking it a day at a time," Todd says. "There are no
guarantees. But I'm so gratefUl for Providence, for Dr. Mega,
for the study. We got our life back Whether it lasts for 30 years,
or 10 years or 10 more months, we've gOt our life back" _
On the seem that heart disease and Alzheimer'S have little in common. It turns out, however, that they share many of the same risk factors.
To lower your risk, Dr. Mega suggests adopting these
ingnew things creates new networks in the brain, much like new growth shoots on a tree. This is a defense against the plaque-building beta-amyloid protein, which does the opposite by pruning
Foods containing omega-3 fatty acids, for instance, help brains function, while a diet high in saturated fats is believed to help beta-amyloid plaques grow.
