A couple days ago we had a March Babies birthday party here at the house. It’s a tradition my sister started a few years ago because so many of her friends have birthdays in March, and this is a great way to kill a bunch of birds with one shotgun. As I was sitting listening […]
More on the brain’s default network: The default network in the brain is considered a “second brain” because it turns on when the rest of the brain is at rest, and turns off when the rest of the brain is at work. Normally, that is. As people age, the default network is less and less […]
Yesterday I asked my sister—who is visiting from abroad—what signs of Alzheimer’s she sees in herself. She rattled off some memory problems such as forgetting names of acquaintances or not being able to place someone’s face when out of context. Nothing particularly Alzheimersy, just decreased mental sharpness. She then asked me if I was experiencing […]

Deep In The Brain is a cerebral self-examination written by a philosophy professor who was riding the top of a success wave when he was diagnosed with Parkinson’s. Talk about the relationship between mind and brain! Here is one who, thanks to his training, steps outside himself to make an objective assessment of his behavior […]
Yesterday I finished reading Still Alice. I think the title is meant to be a loaded question. Can I, after losing all memory of others and self, still be considered to be myself? Am I still “me” if I don’t have a clue what that me is or was?
The fictional book answers the question affirmatively.
I found myself examining my perceptions of Mom–who obviously no longer knows herself–and thinking the conclusion was absolutely true. I still recognize Mom in this shell of a person. She still has the same mannerisms, exudes the same kind affection, displays the same funny reactions. She’s still Mom down to the core.
But not so much with Dad–a victim of Parkinson’s. It seems I recognize him less and less. But then, I suppose I’m holding a higher standard of “self” to Dad, giving that I’m assuming he’s more “there” than mom. If I were to strip him down to mannerisms alone, I would probably find him to be his old self too. It’s a tricky question.
At the very end of the novel, Alice has a moment of lucidy and says, “I miss myself.”
That statement struck me to the core. You know why? Because I miss being me too! There is this incredible longing inside me to be “more” or “better” or “fuller” or something. I fall way short of the me I want to be, and I long for (or miss) that. Yet I still want to be treated as though I were fully “me” even though I don’t meet my own standard for myself.
Why not, then, treat the Alzheimer’s victim as though they were fully themselves, regardless of how short they fall from the perfect version of that self?
Ultimately, our longing is for acceptance, love, safety. Let’s just make a pact to offer it unconditionally to each other regardless of where we are on this journey toward the perfect self.
Alzheimer’s and the Ego: the Power of No
As I was sitting listening to our various conversations around the table, something struck me as different this year. We’re all hovering around 50—give or take a couple years—and the aging process is beginning to take a more prominent seat at the table. Not only do conversation topics start with the premise of aging: declining health, the cost of health insurance, etc, but it seems that no matter what the topic, it eventually touches on something to do with aging.
A curious thing happened to me on my way to finding the cure for Alzheimer’s all on my own: I gained more respect for drug research companies, for neurologists, for folks who are obsessed with theories and practically live in their labs trying to prove their theories. More specifically, I gained greater respect for drug companies that fail colossally, then dust themselves off and try again.
After Eli Lilly revealed that their latest trials of the Alzheimer’s drug semagacestat resulted in greater dementia in their subjects, the response from the public was overwhelmingly angry. Adding to Lilly’s revelation, a recent report on Alzheimer’s drug company stocks by NeuroInvestment painted a bleak picture of the effectiveness of Alzheimer’s drug development across the board, giving the impression that research in the field is pretty much a crap shoot.
If you follow the very well-attended Alzheimer’s Reading Room online, you will see an interesting reaction to these reports. Richard Taylor (who suffers from Alzheimer’s) is one of many who feel crushed and devalued by the repeated failures of Alzheimer’s drug trials. Imagine trying to live with hope, then seeing over and over again that no matter how much money and time is spent on Alzheimer’s research, reality refuses to sustain any hope.
No matter the good intentions, Alzheimer’s research seems a recipe for failure.
This week I got a wee taste of what things might look like from the inside of these drug companies. For the past few years, I’ve been building a theory of Alzheimer’s of my own and keeping my eyes peeled for evidence that would support my suspicions. More recently, I decided to take a serious look at my hunch and see if a) I could gather legitimate scientific data that would shed light on my “theory,” and, b) see if this data had any kind of flow to it—if it had a “storyboard.”
My motives were twofold: I like to discover truths; and I very much want to avoid getting Alzheimer’s (like my mother). Curiosity and Fear fed my research. When I finally thought I had an airtight storyboard, excitement at the implications led to action: I shot off my “storyboard” to a leading researcher in the field.
Sobriety set in the next day. I took another look at what I’d written, then re-checked my sources and found not just one, but several really weak extrapolations in my thinking, and one particularly week substantiation of the evidence. I should have waited. I should have spent another eight weeks (I know, right?) researching before putting it out there and risking embarrassment.
But think about it: the possibility of being right on something so devastatingly urgent will make people take risks. And I’m not talking only about the drug companies; people signing up for drug trials are equally taking risks, knowing that the outcome is not certain at all. When you consider that it takes years and years and years to move inches in the direction of a safe and effective drug release (such as the six years it took to find how a fine-tuned alternate to semagacestat About a decade ago, Dr. Greengard and his postdocoral students made their first discovery on the path to finding the new protein. They got a hint that certain types of pharmaceuticals might block beta amyloid. So they did an extensive screen of pharmaceuticals that met their criteria and found that one of them, Gleevec, worked. It completely stopped beta amyloid production. That was exciting, until Dr. Greengard discovered that Gleevec was pumped out of the brain. Still, he found that if he infused Gleevec directly into the brains of mice with Alzheimer’s genes, beta amyloid went away. ‘We spent the next six years or so trying to figure out how Gleevec worked’ on gamma secretase, Dr. Greengard said. He knew, though, that he was on to something important.functioned in mice), the urgency for a cure leads all sides to gamble on a shortcut. And we’re not interested in companies that aim to keep the Alzheimer’s victim home “three months longer.” We want a cure.
Colossal goals risk colossal failures.
Can you just imagine what went through the minds and guts of Lilly’s leaders when they realized they’d failed? When they had to go out there and tell their shareholders of their failure?
“Well, there’s good news, and there’s bad news. The good news is that our drug was more effective than the placebo…”
Of course drug companies are going to be motivated by the excitement of financial gain. But they’re also going to be motivated by the fear of getting it wrong. They know what failure can do to their reputations and their ability to fund further research.
Today, Indystar.com published a very thoughtful article on Eli Lilly’s semagacestat trial failure. You won’t have to wonder what it was like behind the scenes at Eli Lilly—the article gives you a pretty well-rounded look. You also won’t have to wonder what someone’s response would be after being given the drug and having it backfire. From the wife of one participant:
“I just hope the researchers dig their heels in and keep trying to find a cure,” Dianne said. “That’s the important thing.”
I know there’s the whole layer of marketing that plants diseases into people’s conciousness so drug companies can make money off their fears. For this there is a solution: TiVo (and the advice of a good doctor).
But we shouldn’t assume that everyone researching Alzheimer’s has only one goal in mind—to get into our pockets with random, pointless medications. Any rational company would avoid this particular field: the risk of failure is pretty much guaranteed.
I hope we can learn from Eli Lilly and other Alzheimer’s research companies to risk failure; to work even harder; to join forces in finding a cure.
The other night I attended an author’s reading of a first-time novel.
The main character in the novel is an immigrant computer programmer with terrible social skills trying to navigate his way around the American culture. His mistakes are endearing and a good mirror into the idiosyncrasies of American culture.
In the question and answer period of this reading, someone shot up their hand and asked if the main character suffered from Asperger’s Disease because of his mental brilliance and social ineptitude.
I think the author’s answer was something along the lines of “uh…” which mirrored my own reaction to the question. I’d smiled at the word Asperger’s and felt my stomach lurch at the word Disease. I’ve always thought of Asperger’s more as a cool color to be rather than a disease. Besides, why the need to label?
Why can’t we just accept a different package of assets and challenges in a person and enjoy their uniqueness rather than feel the need to cubbyhole folks into categories?
I just looked up the number of brain-related disorder labels and found a list of 50, among them “intermittent explosive disorder” which is basically the display of temper tantrums. Get real, folks!
What are labels & diagnoses? Something to shield other people from us as well as something to hide behind?
My recommendation for anyone suffering from excessive labeling (both giving and taking) is to read the book “You are Special” by Max Lucado. The interesting notion in this book is that positive labeling can be as harmful as negative labeling because it enslaves us to other people’s opinions. Freedom comes in checking in constantly with our Maker and knowing He loves us as we are.
Read and re-read and practice what you read.
Dare to be yourself.
Yesterday a social worker came to the house to evaluate Dad for possible in-home care assistance. It was a thoroughly humiliating experience for Dad.
The list of questions issued were designed to find out exactly what Dad can and cannot do for himself. The fact that Dad can’t do much at all for himself is something we try not to throw in his face even as it happens. Every time Dad can’t sit in the chair correctly and a struggle ensues to find the right verbal or physical cue to help him do so, Dad’s self-esteem takes a dive. Every time he can’t find a certain room in the house… can’t tell time… etc. So when a list of questions comes along and lays out each and every one of his deficiencies in one sitting, piling them up in front of him like so much garbage to be hauled around, well, it would be an understatement to say it was humiliating.
The further we got into the questionnaire, the more Dad’s countenance fell. It got to the point that I let Dad tell the social worker that he had no problem doing x or y or z, even though I knew the truth.
We ended up somewhere between the truth and Dad’s dignity, honoring neither.
At the very end, this wise social worker asked a question that was clearly not on the list. She asked, “Do you like to fish?”
You could see the dark cloud lift from over Dad’s beaten-down self! A tiny bit of affirmation in the midst of all that pummeling! Never mind that Dad can’t do it anymore; the question at least allowed him the pleasure of showing a positive side of himself. For once, he got to answer a very truthful “yes!”
And that made me wonder: why can’t we–in the pursuit of scientific correctness–remember the spirit of a man? Why can’t we sprinkle questionnaires with bits of affirmation for the sake of dignity alone? Would it hurt science or government to ask “what’s one of your favorite books?” to a woman applying for food stamps? Or “what superpowers would you most like to have?” to a veteran seeking disability assistance? Shoot, while I’m at it, can we change the the category from “seniors and people with disabilties” to “seniors and people with abilities”? There are always things we can still do; things we still like; things we still dream about.
Just stuff I wonder.
And you? Do you have any beef with questionnaires?
We already know that a Mediterranean diet helps stave off signs of dementia, but who wants to eat flavorless vegetables all the time?
If you think you have to sacrifice that deeply satisfying taste of butter and meat that you don’t typically get in a vegetable-rich diet, you don’t know Yum Sauce! This sauce is of Japanese origin and is full of protein, B-complex vitamins (B1, B3, B6, B12), and antioxidants—and best of all, it rounds out the flavor of anything you put it on with a “meatiness” that will satisfy the carnivore in you.
The dish pictured here is a prime example of a Mediterranean diet with a Japanese twist: a bed of baby spinach leaves with sauteed butternut squash, topped with Yum Sauce. Use this sauce on any steamed vegetable, over rice, or even on salad, and you’ll be on your way to fighting memory loss!
1/2 cup olive oil
1/2 cup water
1/2 cup nutritional yeast
3 packets of lemon or orange-flavored vitamin C
2 Tbsp soy sauce
4 Tbsp almond butter or peanut butter
2 cloves crushed garlic
1/2 cup black beans with juice
1 tsp cumin powder or curry powder
1 tsp white pepper
Throw everything in a blender and puree until smooth. Store in a refrigerator for up to one week.
I just finished reading Peter Whitehouse and Daniel George’s book The Myth of Alzheimer’s.
How dare you! you want to say when you first see the title. My mother went through hell with this disease, and you’re saying it’s all imaginary? HOW DARE YOU!
Then you read the book and understand.
I’m not sure I agree with the entire revision of the story of Alzheimer’s, but I did like the tenor of the book. It’s compassionate toward those who suffer from dementia and even more so toward those who suffer from the stigma of dementia. It is angry at Big Pharma—the machine that markets fear of dementia so they can sell their mostly ineffective drugs. And it is angry at the medical establishment that succumbs to that marketing—toward doctors who accept gifts (in disguise) in exchange for prescribing Big Pharma drugs to their patients.
Dr. Whitehouse stresses that he was one of the cogs in that machine. His research helped write the story of Alzheimer’s as a disease, and his advice was sought after by pharmaceutical companies as they worked to develop drugs like Aricept and Namenda.
He was part of the machine until he realized he had helped create a monster that now feeds on the stigma of dementia such that no one is allowed to age with dignity if aging includes any level of dementia. The stigma of dementia has been blown up so large that anyone with a tinge of it is considered finished. People are no longer a mixed bag of assets and deficits. Once a person’s memory starts to go, he has no value unless the “deficit” is “fixed.”
Dr. Whitehouse points out instead that even with cognitive deficits, human beings still have plenty of assets to draw from in living fully satisfying lives.
So what is the myth?
How much time is enough time? We know we are mortals and we know life is but a breath. In light of eternity, we calculate that 100 years passes as quickly as twenty. Yet, given anything less than 100, and we say we’ve been “cut off.”
My big, strapping brother-in-law lays in the hospital right now, fighting for each new minute after a two-year battle with brain cancer. He is tired, and he is ready to rest. We would prefer the doctors find a cure and make him bounce back, but we want to let him go.
Throughout this whole battle, Ken’s mind worked around his brain to bring humor and gratitude to his situation. He firmly believes God’s purposes can be worked through the worst tragedies, and it is amazing to hear how his concerns were always for the eternal perspective he could bring to the waiting room, the surgery room, the recovery room.
Ken’s life may be cut short in our view, but it has been a life well-lived, and that’s more than a lot folks can say. Socrates said that an unexamined life is not worth living; an anonymous person added that an unlived life is not worth examining. I can vouch for Ken that he’s had a life worth examining.
April 26, a.m.: Ken had a brain hemorrage last night and is on life support. Awaiting a family gathering to let him go.
April 26, 7 p.m. Goodbye Kenny. From someone who was present at his bedside: ” just wanted to write and let you know that Ken’s passing was beautiful in the midst of family and hymns and Scripture. The more that Daniel read and Ruth recited the easier his respirations…and soon he just passed on.”
We already miss your booming laugh, your exhuberant living, and your unwavering faith. Save us a place at the banquet table, and we’ll see you in the morning.
Here’s a short section of a CNN interview of Michael J Fox done by Sanjay Gupta—about living with Parkinson’s:
“Liberating” is what Michael calls his Parkinson’s! A chance to do something significant with his life! The turning point? The diagnosis. The act of giving a name to his symptoms allowed him to take back control of his life. Wow!
I cried throughout, of course, because Dad’s Parkinson’s was nothing liberating. But the reason it was such a cage, I think, is that it went undiagnosed until the very end. His shaking was written off as “familial tremors” (like his father and brothers who likewise had hand tremors without Parkinson’s) for twenty years, so all his other symptoms—an expressionless face, shuffling gait, forward tilt, drooling, even dementia—weren’t blamed on a disease: Dad had to take the blame himself.
I’m sorry, Daddy. How freeing it would have been to know your body was beyond your control. I think it would have helped your mind to gain control over your brain.
I hope this will convince anyone out there who suspects they may have Parkinson’s to get a thorough neurological examination. Take control of your disease and don’t let it eat up the rest of your life.
Today the world has been given the very bad news that there is nothing that can help prevent or slow the progression of Alzheimer’s. The disease is a thief and a murderer, and nothing can stand in its way.
I say the folks who did these studies need to study Mom. Round out the evidence of all that hopeless progression with a little taste of surprising regression.
I wrote the rest of this post a week ago, but only got around to publishing it today:
Mom is going backwards. She’s regressing, it seems to us, and that’s a good thing when you have Alzheimer’s.
How? What? When? Where? Why? Is it wishful thinking that we’re seeing marked improvement in Mom’s cognition, or is this real?
Exactly what I’m asking myself these days. Granted, being a highly motivated observer may make my observations suspect, but I feel it would be irresponsible not to report what appears to be clear evidence of improvement in Mom’s condition. It would be irresponsible of you not to suspect my findings, but dumb not to take a look at all.
So here goes.
A few weeks ago, we who have been taking care of (or been around) Mom for the past three years noticed that we were telling people Mom was having a good month. We were used to telling people that Mom was “having a good day” every now and then. A good day once a week was a good thing. But the entire month of March of this year seemed to be “a good day.” It came to the point that we were scratching our heads saying, “Hmm. Maybe Mom doesn’t have Alzheimer’s. Maybe this was all stress, and now that she’s been de-stressed for three years, she’s coming back.”
So I decided to take inventory of the new signs of cognition (and physical improvement) coming from Mom these days. What exactly is she doing that she wasn’t doing before? This is what I have:
- Mom has gained weight. Exactly a year ago Mom weighed 85 pounds and was bed-ridden with pneumonia. Hospice pronounced her a week from the grave. Today Mom weighs 95.5 pounds. No sign of physical sickness (OK, an occasional night fever and drippy nose).
- Mom sucks from a straw. For the longest time, we were having to “prime the pump” to get Mom to suck from a straw. A year ago, when we put a straw in her mouth, nothing would happen. So we’d plug the straw with our finger, then release the contents into her mouth, and, voila, she’d start sucking. Now Mom sucks as soon as the straw hits her lips.
- Mom opens her mouth at the sight of food. Again, for the longest time we’d just get a pleasant stare when we lifted a fork to her mouth. Two years ago, it would take us a good hour and a half to get through breakfast because it was only one time out of ten that Mom’s lips would part when we brought food to her mouth. Now, six-seven times out of ten, her mouth opens like a baby bird’s. Breakfast time has been cut in half.
- Mom swallows. Up until (this is where I wish I’d kept an exact diary) about four months ago, Mom had a permanent sore on the right side of her mouth. This was caused by the fact that Mom leans to the right when she sleeps, and food that remained in her mouth (because she wasn’t aware enough to swallow) dribbled out and ate at her skin. No matter how well we brushed her teeth and how much Vaseline we slathered around her lips, the sore was there off and on for the last three years until–a few months ago. The sore has not returned.
- Mom watches TV now. Meaning, she actually turns to it, focuses on it, and laughs on cue–sometimes for a 10-15 minute stretch. This hasn’t happened at all in the past three years until this “awakening.”
- Mom stops at the photo gallery in the hallway, looks at individual family photos and “comments.” For the past three years we’ve been walking through the hallway with Mom–past a 4 foot x 4 foot photo gallery–occasionally stopping to show Mom the family photos in hopes of getting a response. She wouldn’t even look where we were pointing. And if she focused at all, it would just as likely be on a knot in the wood frame as on a photo. Now Mom takes the initiative to stop and look from frame to frame, pointing, jabbering, looking at us and back at the photos. Sometimes getting teary-eyed at our description of the photos.
- Mom is using sentences. I wrote in a previous post that Mom’s language consists almost entirely of two syllable experiments in sound with an occasional word thrown in. We used to get so excited when she uttered a word that we’d call a family member and share the big news. In the past couple weeks, Mom has used short sentences. Like three days ago when I put her to bed, I said, “Mom, I love you.” She nodded and said, “For me, for me, for me too too.” The next morning at breakfast I tried to give her some juice while she was still chewing on her eggs and she shoved my hand aside and said “Put it down down.” I put her down for a nap in the afternoon, put on some Vivaldi, and did a farcical ballet dance (a la BodyVox). She nodded and said, “Yes. I do too too too.” Then that evening when I tried to give her her Seroquel (ground up in some juice), she shook her head. I kept bringing the juice to her mouth, and in exasperation she said, “Tsk! What what what do you do?” (Translation, “cut it out!”).
Four sentences in two days! Yesterday was a quiet day for Mom. No miraculous signs of anything. I’m dying to report more on this healing process, but Mom is not a science project, and I have to remember that she is worth all my love no matter what direction her mind and body take.
But I do think it’s worth mentioning that something has happened to Mom that has sent this Alzheimer’s into some sort of retreat. There is more than death taking place in her brain. Somewhere, somehow, regeneration is taking place as well.
Have any of you had the experience of watching a loved one with Alzheimer’s have a good month? I know Bob DeMarco recently reported an extraordinary event with his mother Dotty. Huge “regressive” step.
Next question will be, what could be causing these amazing regressions? We may have to rely on each other–the caregivers–to find the answer rather than on lab tests alone.
So I re-listened to the Fresh Air segment today, then did some quick digging through articles I’ve seen online on the brain, stirred it all around, let it simmer some more, and here is the reduction I got.
Maybe our addiction to the pursuit of happiness is contributing to brain aging. It’s not an umbrella cause, of course. You would never have been able to say that Mom led a hedonistic lifestyle. And Ronald Reagan pursued a lot more things than happiness. But still… The connection between what Dr. Linden was saying and what I’ve read makes me suspicious.
In David Linden’s Compass of Pleasure, he talks about the pleasure area of the brain as being that part that–in response to certain activities or substances–produces dopamine. Dopamine is the “feel good” neurotransmitter in the brain. It is activated when we engage in certain activities or thought processes, but it is also activated when we injest/inject food, alcohol, narcotics.
Some things that produce dopamine are completely healthy. Like a good run, the enjoyment of friends, reading a stimulating book.
Some things are borderline good. Like food. Everybody needs it. The pleasure of good food produces dopamine. But when pleasure is sought after for pleasure’s sake, “the brain’s dopaminergic circuitry gets blunted. In all cases of producing pleasure in the brain, it takes increasing levels [of a thing] to produce the same level of pleasure” (quoting Dr. L). So with food, you eventually get overweightness if the pleasure of food is pursued beyond the body’s need for it. Obesity is contributing to an epidemic of Diabetes, which is strongly linked to brain aging. By indirect means, then, the pursuit of a happy palate can lead to brain aging.
Then there are things that produce dopamine (or cause its production) that are not healthy. Like alcohol, nicotine, cocaine. This falls in with the acetaldehyde hypothesis I wrote about in Does Alzheimer’s Take Guts. Alcohol, cocaine, and especially cigarette smoke have–at some point in their metabolic breakdown–the toxic aldehyde acetaldehyde. Very destructive to the brain. Dopamine is produced as the end-process of breaking down harmful aldehydes into harmless acids. It’s the brain’s “Yahoo!” after saving the day from the bad guys. That “Yahoo!” may be a good thing, but again, in order to get it a second, third, and nth time, you have to increase the attack on the body. [Interestingly, Disulfiram's use to treat alcohol and cocaine addiction works by inhibiting ALDH2 (aldehyde dehydrogenase) which is the enzyme that metabolizes acetaldehyde. It lets the toxin do its full work rather than disabling it by metabolizing it into a harmless acid. So the brain does not get its "yahoo!" And if you get no yahoo, you don't repeat the action.]
The problem with focusing on happiness above all else is that we may end up using the short-cut and more harmful methods of getting that dopamine high.
Dr. Linden’s solution? “Try to take your pleasures broadly: exercise, meditate, learn, have moderate consumption of alcohol, moderate consumption of food.”
I would add: pursue friendships, do charitable work, tend a garden, read a good book (get more ideas at Changing Aging).
As Captain Kirk once said, “There are a million things you can have and a million things you can’t have. Choose the million you can.”
The other day my sister saw a note I had written on a sticky pad. It was a list of things I needed to do, one of them being to order a refill of Mom’s Seroquel. Except my sister read “Mom’s sequel” and thought I had written a book about Mom and was now working on a sequel. Not a far-fetched idea, as I’m always writing some book or other under the covers with a flashlight (so to speak).
Turns out I’m not writing a sequel about Mom.
Unless I’m writing it with my life.
In my last post I expressed fear that I might be following in my mother’s footsteps. Who wants to inherit Alzheimer’s? But the more I think about it, the more I would be proud to be called my mother’s sequel. I’m certain that anyone who knew Mom would give their right arm to be compared positively to her. She was the most selfless person I’ve ever known. The prayingest person I’ve ever known. The best cook, the best artist, the most humble…
I can remember a couple tizzy fits Mom threw right in the middle of menopause. But dang, other than that it’s hard to think of anything bad coming from Mom.
So I have to say that it is with great pride that I would love to be able to say “I am my mother’s sequel.”
One thing Parkinson’s can’t take away from a man is all he has passed on in his lifetime. Here is Dad, rock-hounding Parkinson’s style. The fact that he can’t stand up on his own or kneel and claw through the dirt to get to the jasper or petrified wood doesn’t detract from the fact that he instilled the love of nature and science in his children. It’s in our blood now to visit all the national parks we can and to dig for fossils wherever there be beds.
He’s taught his children so many good things, and Parkinson’s can’t take that away from him.
Here is something frustrating about clinical trials of Alzheimer’s drugs: the FDA requires that such trials show an almost immediate improvement in memory tests of participants in order for the drug to get approval, disregarding improvement in other symptoms, and consequently derailing a possible cure for this dreaded disease.
Here is why I think there is an inherent problem with this guideline:
If you go the the Alzheimer’s Association website and take the interactive tour of a brain with Alzheimer’s (a fantastic tool!), you will notice that there is a general pattern to the progression of Alzheimer’s and its accompanying symptoms. Specifically, looking at slide 13 you will see that the first part of the brain to be affected by Alzheimer’s is the inner core where the hippocampus resides—that part of the brain responsible for short-term memory. From there, damage spreads outwards to the cortex of the various lobes. As the second image in slide 13 shows, the Frontal Cortex is affected in mid stages of Alzheimer’s. This area is responsible for attention, social skills and intelligence (or wit). It is associated with “personality.”
Now, if an effective drug for Alzheimer’s were to be developed, you would expect to see the least damaged areas respond first, followed by the most heavily damaged areas.
Such were the preliminary results of the clinical trial of Dimebon. In reading the various anecdotal accounts of the Dimebon trial (see Bob DeMarco’s piece on the Alzheimer’s Reading Room), the results seemed to show precisely this initial response: Alzheimer’s sufferers reported increased alertness, social skills, and wit. Here is a sample quote from the various testimonials:
The major drug companies are focusing on memory. Are they after the right target? I’ll tell you this, in weeks 6 through 18 in the Dimebon clinical trial my mother was more engaged with me, more aware of her surroundings, more interesting, and more like her “old” self then she had been in six years.
The least damaged areas of the brain were affected in the 12-week trial! Then the trial was stopped because the inner (most damaged) area of the brain showed no marked improvement.
Would it not make sense to glean from the trial that a logical reverse course of the disease was set in motion and to continue it to see if the pattern held?
Pfizer et al, could you give us another 12 weeks when studying Alzheimer’s please?!
[Note: this analysis is mine alone. It may not be true that the least affected areas would show improvement first]
