The Alzheimer’s Research Paradigm If you’ve every studied philosophy of science, you’ll recognize that current research in the field of Alzheimer’s Disease is battling paradigms. The funny thing is, the Alzheimer’s field hasn’t even reached the level of robust theory, yet there is strife in the ranks of researchers fighting over the direction inquiry should […]
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 […]
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 any unusual mental hyperabilities and went on to explain how she seems to have gained a fantastic ability to call up words she didn’t even know she knew.
Funny, I told her. I had this post saved as a draft when she asked me the question. The answer is yes, I’m experiencing this very same thing, and am curious to know if there is a name for it.
Is there such a thing as hyperphasia—the flip side of aphasia? The term hyperphasia exists, and it’s defined as an uncontrolled impulse to talk. But that’s not what I’m referring to. I’m referring to the mind’s sudden ability to pull up obscure words when common words won’t present themselves. Words so obscure that we had no idea we knew them.
I’m well acquainted with aphasia—the “tip of the tongue but it just won’t come” nature of language loss. I’m also familiar with another embarrassing result of gradual mental decline: the mind’s tendency to call up words similar in shape, but wholly different in meaning from the one the user wants. Try Googling “fairy schedule” next time you want to cross the Puget Sound to see what I mean.
But what is it called when the mind calls up unknown words that perfectly fit the context they were intended for? Does neurology study mental surfeits as well as deficits?
I told my sister that I’ve had arguments in my head over this new ability. One night, for example, I went to bed, and as I lay my head on the pillow a picture of our living room doorway came to mind, and with it the word “transom.” I immediately questioned myself:
“Transom? What’s that?”
“It’s the big piece that spans the top of the doorway, dummy.”
“How’d you know that?”
“I don’t know. I just know that it is.”
“You’re probably thinking of Hansom. And I think that’s a horse carriage, not a doorway.”
“No, I know hansom is a carriage. Transom is the door thingy.”
With that, I got out of bed and looked the word up in the dictionary: a horizontal crossbar in a window, over a door, or between a door and a window or fanlight above it
“OK, you were right.”
My sister laughed and said, yes, that’s exactly what goes through her brain.
So my question is, what is this newly acquired hyper-phasia called? And is it common to everyone as their minds begin to deteriorate?
The topic of fasting and Alzheimer’s has been on my mind lately because, well, Alzheimer’s is always on my mind and because recently a friend of mine got on this diet where you’re supposed to eat six small meals a day to trick your body into not storing fat.
Since intermittent fasting has been shown to slow body and brain aging, I wonder (the fat part aside) what this continual eating is doing to the brain.
From Psychology Today (2003):
It has been known for years that sharply restricting the calorie intake of laboratory animals increases their life span. But a new study by researchers from the National Institute on Aging found
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.
I don’t know how much I’ll be able to write about Parkinson’s here. If I write about Parkinson’s, it’ll be about how it’s affecting Dad. And if I tell you the things this disease makes Dad do, you won’t have a pretty picture of Dad. And that ain’t fair.
Here’s just a little, white example. A couple days ago Dad had to go to the bathroom. He asked what direction the bathroom was, and I pointed it out. He walked to the bathroom door, then asked me again where the bathroom was. I told him he was standing at the bathroom door. He said, “And now what?” I explained that he had to walk over to the toilet. He was standing four feet from the toilet and asked, “Where?” I put pressure on his back and gently led him to the toilet. He said, “And now?”
I had to help him through the whole process.
The concept “how to back up” seems to be the biggest obstacle his brain has to overcome. He can’t figure out how to back up to the toilet before sitting, or once he’s in a chair, how to back up from the edge. The same when he goes to bed.
My sister and I try “scoot back, Dad.” He scoots forward even though he’s already on the edge of whatever. We try changing the cue. “Put your back here” (while patting the back of the chair). Nothing. “Lift your bottom and move it back.” Nothing. Yesterday I tried switching languages. I said, “Put your butt in reverse” in Portuguese. He couldn’t do it, but he did double over laughing. And that’s a huge gift.
But these gifts are hard to come by. So I probably won’t write much about Dad and his Parkinson’s. I’d rather you see the adventurous man who loaded up his wife and eight kids in a van and drove from New York to Bolivia in 1966. This man taught us all kinds of good things about nature and God, and I’d rather not leave you with a highly unbalanced picture of who he is.
On Saturday, August 21, 2010, God took Dad home. God did not wait until we were ready for this. He waited until Heaven couldn’t stand Dad’s absence any longer.
I’m posting this video about how we deal with death in our current culture because I think our attitude of denial in the face of death needs to change. Considering my family’s immediate reaction of trying to revive Dad–even though he requested a DNR–I’m speaking from experience. Our natural tendency is to hold on as long as possible. But this isn’t necessarily the best for those we love.
Letting go is so stinking hard!!
All the more reason to think and plan ahead for the death of those you love.
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.
I took Dad for a walk tonight. It wasn’t a long walk. Dad was tired and didn’t really want to go. But he acquiesced to my prompting, and we walked to the end of the 50-yard driveway.
The whole time we walked, I supported Dad’s right arm. And the whole time we walked, Dad’s arm shook violently. By the time we got back, my arm was buzzed and aching.
Then it occurred to me that if Dad’s energy gets passed onto me in this bad way, perhaps we could harvest the energy in a good way. I suggested to him that we design something like the soccer ball recently invented by those Harvard girls—you know, the ball that stores the energy of a game’s worth of kicking into a battery that can then be used to light up the Third World.
But hey, why not harvest the energy generated by Parkinson’s tremors? Maybe we could even wire the energy back into the brain for deep brain stimulation therapy.
There’s got to be an up side to the down side of this energy-depleting disease!
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.”
If you click on the picture at left, you'll hear the loveliest little story about a nursing home in Germany that decided to install a fake bus stop in front of their facility for patients to go to and "de-stress." Folks would go out to the bus stop thinking they'd get on a bus and go home. But after a few minutes of waiting, they'd forget why they were there and go back inside, no longer agitated and afraid.
So, if lying achieves a good end, is it OK?
Looking at it another way, is the aim of interaction to be correct or to be kind?
In the bus stop story, think about what it is the patient really wants when he waits for the bus. He wants home and family. But why? He wants these things because they mean acceptance and love.
So if the bus stop allows a patient to calm down enough for a staff member to have a soothing, friendly visit with them, is it not giving them what they were after in the first place? And is this not Truth?
This is the same rationale for communicating with Alzheimer's patients even when they are home with family. The point isn’t to constantly correct your loved one ("no, it’s not morning, it’s evening;" or, "no, my name isn’t Mary, it’s Marty"). We’re not here to elicit factual correctness from each other, but to honor each other as full-fledged beings created in the image of God—regardless to what extent we are broken.
And, no, I'm not a post-modernist saying there are no facts, or that facts are what we want them to be.
Just saying, facts aren't the point. Love is.
Trying to follow Alzheimer’s research sometimes feels like walking through an Escher exhibit: the contradictions can border on the absurd.
Take the new findings on SIRT1 and its relation to Alzheimer’s. Research after research shows that SIRT1 apparently protects against Alzheimer’s:
25 July 2010. The sirtuin protein SIRT1 is emerging as an important player in learning and memory, and may have potential as a therapeutic target in Alzheimer disease. Fresh on the heels of a July 11 Nature paper that demonstrated a crucial role for SIRT1 in memory (see ARF related news story on Gao et al., 2010), two new papers add to the growing body of evidence that SIRT1 helps keep brains healthy. In a paper appearing July 21 in the Journal of Neuroscience, researchers led by Valter Longo at the University of Southern California, Los Angeles, show that a SIRT1 knockout mouse has numerous defects in learning and memory. This finding implies that SIRT1 could have a protective role in AD, and indeed, in a July 23 Cell paper, researchers led by Leonard Guarente at the Massachusetts Institute of Technology, Cambridge, report that overexpression of SIRT1 can decrease Aβ production and the number of amyloid plaques in a mouse model of AD.
You’d think, then, that more SIRT1 is better for Alzheimer’s and less is worse. But:
Michán and colleagues also examined a transgenic mouse that overexpressed SIRT1 16-fold in the brain. On this normal mouse background, the authors found that this massive SIRT1 overexpression conferred no improvements in learning or memory, and that synaptic function was unchanged except for a slight increase in neuronal excitability.
And though less is worse, vitamin B3 in the form of niacinamide has been shown to “cure” Alzheimer’s in mice by decreasing the expression of SIRT1: Nicotinamide Restores Cognition in Alzheimer’s Disease Transgenic Mice via a Mechanism Involving Sirtuin Inhibition and Selective Reduction of Thr231-PhosphotauWe evaluated the efficacy of nicotinamide, a competitive inhibitor of the sirtuins or class III NAD+-dependent HDACs in 3xTg-AD mice, and found that it restored cognitive deficits associated with pathology. Nicotinamide selectively reduces a specific phospho-species of tau (Thr231) that is associated with microtubule depolymerization, in a manner similar to inhibition of SirT1. Nicotinamide also dramatically increased acetylated -tubulin, a primary substrate of SirT2, and MAP2c, both of which are linked to increased microtubule stability. .
When asked about this contradiction, Dr. Greene, one of the researchers on this paper says,
You are correct – there are contradictions between the role of Sirt1 in AD. Regardless of these, nicotinamide has good effects in the preclinical models, and has been shown to now be effective for other neurodegenerative diseases as well. Sirt1 may be beneficial at some stages of the disease, and not others – we cannot [reconcile] these differences at this stage, but our research says that nicotinamide is highly effective in preclinical models and that inhibition of Sirt1 plays a role in these effects.
My mind wants to hyperventilate with the contradictions, but then I remember the story of the three blind men describing an elephant and realize the contradiction exists only because we do not yet fully understand.
And that’s what drives research onward.
The first thing you have to know about Mom is that she is the biggest sweetheart on the planet. She has always said “yes” to anyone who asked her for a favor or a meal or a ride or even cash. We used to berate her over some of these decisions. “Mom, you’re just enabling them to go get drunk,” or whatever. We’d rather keep our boundaries intact. Keep safe. Not Mom. She’d rather “do onto others” as Jesus wanted her to do–and let Jesus take care of punishment if the recipient abused the gift.
With that in mind, it puzzles me that these days, the word most frequently pulled out of her tiny residual vocabulary (5-10 words at present) is the word “no.”
“Mom, shall we get up?”
“Mom, isn’t this music pretty?”
“Do you want to go for a walk?”
Here’s the curious part. Her body language still says “yes.” So why the verbal “no”?
I’m thinking that this knee-jerk negation is her last recourse to individuality. Having lost most of what makes her a person, she is resorting to negation as a way to distinguish herself from others.
Think about it. “Yes” blends us into other people. It’s a unifying word. It accepts. It serves. It hugs and becomes one with the other.
“No” on the other hand, puts up a wall between the self and the other. It says, I am me and you are you and it’s going to stop there.
It’s Mom’s only way, I believe, to retain a feeling of self.
And that revelation changes how I look at the world. You wonder why some people just can’t play nice in the world arena; why they have to say “no” to constructive engagement; why they have to strap bombs around themselves and “no” themselves and other people into oblivion.
Perhaps it’s because those people feel that a “yes” will blend them into the will of the other–a will that is unacceptable to their idea of a healthy self. A “no,” they feel, is the only way they’ll be seen.
Do you see what I’m saying? The ego’s boundaries collapse under yes. “No” is the last bastion of the tormented ego.
Because it’s Fall and crisp out and a good time to sit down to a good movie, I’m posting one of my favorite suggestions for a movie that deals with Alzheimer’s.
How To Kill Your Neighbor’s Dog is an unfortunate title for a great movie about self-centeredness and the cure for immaturity. The story centers around a playwright with writer’s block who must exit himself in order to find inspiration. Alzheimer’s isn’t the main theme of the movie, but it is present in the background, and the most lucidly-spoken scene in the movie is between the mother-in-law with Alzheimer’s and her brilliant, unhappy son-in-law.
Thought I’d pass it on.
In continuation of Alzheimer’s and Glucose Metabolism: The Niacinamide Experiment Part 1
This post is simply me mulling over things I’ve read in light of Mom’s dementia and my own experience with stress and mental short-circuiting, with the conclusion that in some cases of Alzheimer’s, intestinal flora could be greatly to blame. My conclusion also points to the possible way niacinamide could function in correcting one of the malfunctions in the gut-brain axis.
The Gut-Brain Axis
In-depth studies of human intestinal microbes are just now coming into maturity. The Human Microbiome Project is fueled by the increasing belief that the population of bacteria and yeasts that inhabit the human digestive tract is greatly responsible for how the body and mind develop and how they continue to function or malfunction as we tinker with the balance of flora in our gut:
Visionaries are hoping for cures for some forms of obesity and anorexia along with various forms of cancer, asthma, multiple sclerosis, Alzheimer’s, lupus, and most of the major psychiatric diseases. In the future, Blaser [of the infectious-disease research lab at New York University] says, pediatricians could help prevent these diseases by infecting babies with a starter kit of friendly bacteria. “Bottom line, humans and our fellow animals have been colonized by microbes for a very long time, going back a billion years. The microbes that we carry have been selected because they are helpful to us. They participate in human physiology. They are a compartment of the body, like the liver or the heart.” (1)
When the BP oil spill happened in the Gulf of Mexico, we were all
A couple days ago a friend of mine called almost in tears: “I did such-and-such, and I’ve never done such-and-such before. Do I have early-onset Alzheimer’s?”
I laughed. “The thing about Alzheimer’s,” I said, “is that they say not to confuse normal aging with Alzheimer’s, and then they say Alzheimer’s hits long before any recognizable symptoms become evident, so you have to look for signs early on.”
So I want to know: are we to be concerned about Alzheimer’s as soon as we lose our keys for the first time, or should we just laugh it off and look at the bright side of life all through the aging process?
Recently, a new mini-test was developed for the easy detection of Alzheimer’s. It’s called the AD8. This 8-question test is supposed to bring a diagnostic tool into the hands of primary care doctors so that Alzheimer’s can be detected earlier and therefore treated more effectively.
The problem is, there is no effective treatment for Alzheimer’s yet. So what, pray tell, are we doing finding new ways to diagnose this disease when there is no treatment and when the disease itself is not even clearly defined?
When we first brought Dad to live with us, we set him up with a primary care doctor who ran him through the standard Alzheimer’s test: remember these three things; tell me the date; where do you live; what floor are you on; draw a clock that says three thirty; etc. Dad got every single question wrong, and the doctor proclaimed, “You don’t have Alzheimer’s.”
I wanted to laugh. I think it was relief that a doctor would buck the system and refrain from offering perhaps a true but useless diagnosis given the lack of any effective treatment.
Later, we took Dad to a neurologist who got through three of the standard questions and suggested he try Aricept.
We gave Dad the five-week trial supply. It profited him nothing.
I’m not saying that we should refrain from diagnosing diseases. From his neurologist Dad also got a diagnosis of Parkinson’s, and as I’ve pointed out in an earlier post, this diagnosis (though it came late in the progression of the disease) was tremendously helpful in understanding Dad’s behavior and in relieving his sense of guilt. The medication he took for Parkinson’s did him no good either, but the diagnosis itself was helpful—perhaps as much for us, his caregivers, as for him.
But Alzheimer’s is a tricky beast. There are some well-known Alzheimer’s victims like Richard Taylor and Dottie (of the Alzheimer’s Reading Room fame) who are now under fire as possible Alzheimer’s mis-diagnoses. How can anyone have Alzheimer’s for six or ten years and show no decline, or even show improvement over time? It is not the subject’s truthfulness that is questioned but the accuracy of the initial diagnosis (heaven forbid we should think Alzheimer’s can be stayed by sheer willpower—of the sufferer and/or caregiver. That would mean we don’t really need expensive meds).
Is diagnosis of value when there are so many causes of dementia that could result in a false positive? And are the statistics of any value when they are repeatedly misquoted? We keep using the phrase “there are 5.3 million Americans with Alzheimer’s” when the correct statistic is “5.3 million Americans with Alzheimer’s and other dementias“.
One last bit of datum against the usefulness of Alzheimer’s diagnoses: in the U.S., whites tend to get diagnosed and treated more frequently than Hispanics, African Americans, and Asians. Whites seek out professional medical care, while Latinos, African Americans and Asians with Alzheimer’s tend to stay home and be cared for by family. Yet whites with Alzheimer’s die sooner than their non-white counterparts.
If earlier diagnosis is helpful, where is the evidence?
