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 […]
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 […]
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 […]
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.
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?
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?

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?
A Compromised Gut and Aging
Suppose we throw out the acetaldehyde-in-the-blood-and-brain hypothesis. Even if the liver can keep up with the load, the process of breaking down acetaldehyde into a harmless acetate itself will upset the NADH/NAD balance.
NAD (nicotinamide adenoid dinucleotide) is the most important co-enzyme in the body. Aldehyde dehydrogenase depends on it to break down toxic aldehydes. SIRT1 depends on it to keep cells from committing suicide. It is the key to glucose metabolism. Etc.
A shortage of NAD is a normal part of aging:
Once pancreatic β cells and neurons start having functional problems due to inadequate NAD biosynthesis, other peripheral tissues/organs would also be affected through insulin secretion and central metabolic regulation so that the metabolic robustness would gradually deteriorate over age at a systemic level. This cascade of robustness breakdown triggered by a decrease in
It's just one doctor after another these days…
We barely got to the clinic and we were both already exhausted: Dad from getting dressed, fed, squeezed into a jacket, compressed into the car, ejected from the car, and hung in a wheelchair. Me from doing all that to him without the cooperation of his muscles. We didn’t even want to go into the clinic. I told Dad that what we should do is write a children's book about aging and how fun it is. Dad laughed. I said we could describe how you get to ride around in a cool scooter—even inside the house. And how you get to have cool leopard print all over your skin without paying a cent for it. And how if you get skin cancer on your ear, you have to have a chunk cut off (like Dad) and then you can fit right in with the folks at Rivendell or Lothlorien.
I really see some potential there.
Might as well take this big old lemon and make lemonade.
(P.S. If you have any more ideas for the book, let me know)
My last post on niacinamide and Alzheimer’s (it’s supposed to reverse Alzheimer’s de-mentiaThe Coenzyme nicotinamide adenine dinucleotide (NADH) has been used as medication in 17 patients suffering from de-mentia of the Alzheimer type in an open label trial. In all patients evaluated so far, an improvement in their cognitive dysfunction was observed. Based on the minimental state examination, the minimum improvement was 6 points and the maximum improvement 14 points with a mean value of 8.35 points. The improvement on the basis of the global deterioration scale (GDS) was a minimum of 1 point and a maximum of 2 points with a mean value of 1.82. The duration of therapy was between 8 and 12 weeks. No side effects or adverse effects have been reported from the patients or their caregivers during the observation period which is, in some patients, more than a year. This open label trial represents a pilot study from which no definitive conclusion can be drawn. A double-blind placebo controlled study is necessary
In my research on Alzheimer’s and glucose metabolism, I ran across a fascinating article about the brain’s default system–that part of the brain that is affected in Alzheimer’s Disease; that part of the brain that hogs glucose like no other part of the brain.
In The Secret Life of the Brain, Douglas Fox brings together research on the default network beginning with Dr. Sokoloff who, in his attempt to find out why the brain uses so much glucose (20% of the body’s supply), discovered that the brain uses as much energy while “at rest” as it does while performing tasks.
Later, a neuroscientist named Marcus Reichle discovered a kind of “brain within the brain” that works its butt off when it’s supposedly in “idle mode.”
Raichle and Shulman published a paper in 2001 suggesting that they had stumbled onto a previously unrecognised “default mode” – a sort of internal game of solitaire which the brain turns to when unoccupied and sets aside when called on to do something else. This brain activity occurred largely in a cluster of regions arching through the midline of the brain, from front to back, which Raichle and Shulman dubbed the default network (Proceedings of the National Academy of Sciences, vol 98, p 676).
It was found that some parts of this network devoured 30 per cent more calories, gram for gram, than nearly any other area of the brain. Since part of this default system is in constant communication with the hippocampus (which records every day memories), Reichler speculated that its function was to sort, evaluate, and categorize memories in such a way that would allow the brain to use the past as an “inner rehearsal” for considering future actions and choices.
Brilliant. Just when you think daydreaming is a waste of time, it turns out it’s crucial for living.
Raichle now believes that the default network is involved, selectively storing and updating memories based on their importance from a personal perspective – whether they’re good, threatening, emotionally painful, and so on. To prevent a backlog of unstored memories building up, the network returns to its duties whenever it can.
In support of this idea, Raichle points out that the default network constantly chatters with the hippocampus. It also devours huge amounts of glucose, way out of proportion to the amount of oxygen it uses. Raichle believes that rather than burning this extra glucose for energy it uses it as a raw material for making the amino acids and neurotransmitters it needs to build and maintain synapses, the very stuff of memory. “It’s in those connections where most of the cost of running the brain is,” says Raichle.
Reichler later attented a lecture by an Alzheimer’s specialist and was shown a map of beta amyloid plaques (those clumps found in Alzheimer’s autopsies) in the brain. The picture looked exactly like the default network!
Raichle, Greicius and Buckner have since found that the default network’s pattern of activity is disrupted in patients with Alzheimer’s disease. They have also begun to monitor default network activity in people with mild memory problems to see if they can learn to predict who will go on to develop Alzheimer’s. Half of people with memory problems go on to develop the disease, but which half? “Can we use what we’ve learned to provide insight into who’s at risk for Alzheimer’s?” says Buckner.
That got me thinking…
Maybe one reason we lose memories is that our lifestyle doesn’t allow for much rich idle time like when we would sit on the porch sipping sweet tea on a hot afternoon. So the default network can never do its work of sorting and categorizing memories, and consequently we lose them.
And if this is a problem with the present generation, how much moreso for the upcoming generation. We are consumed with having something to pay attention to all the time. Just look at TV screens these days: not only do you have the main screen, but there’s the pop-up ad for the “next show,” a caption for what’s going on on the screen, and a ticker at the bottom of the screen for what’s happening elsewhere.
Maybe part of the solution for AD is the “quiet space” to be incorporated in school, at work, and at home. Hmm, come to think of it, I offered this very solution in a comment to an article in Time Magazine back in 09 (Turn Off, Tune In, Log Out):
I predict that the twitterification of our society is going to lead to an exponential increase in early-onset Alzheimer’s. We’re increasing the rate of input to our brains and decreasing the time for processing information, and our brains are going to revolt. That, in turn, will lead to the next big industry: de-twitterification rooms where you can sit alone and unconnected, with nothing but a giant aquarium and a beanbag. -Marty
Eleanor Cooney’s Death in Slow Motion: a Memoir of a Daughter, Her Mother, and the Beast Called Alzheimer’s is not just one book. This is two tales in one: a memoir of desperate caregiving and a biography. The memoir part follows Eleanor’s hyperventilated, drug and alcohol-sustained trek through the five stages of Alzheimer’s caregiving for her mother, Mary Durant, and the biography chapters relate the story of her mother prior to Alzheimer’s (think Dorothy Parker with abundant sex and alcohol) ending with a very rare love story between Mary Durant and Michael Harwood (her third husband). Having the story weave through these two windows makes the reader feel the compounded tragedy of the beast called Alzheimer’s.
You will laugh, clench, oggle, envy, and cry as you read this literary gem.
As a bonus, Cooney includes a previously unpublished short story written by her mother (in a style I would call Flannery O’Connor cum wicked smirk).
Buy it. Read it. Pass it on.
P.S. People who read this book will probably also buy and read Mary Durant and Michael Harwood’s On the Road with John James Audubon. Mine is already in the mail.
Like the title of this blog says, there are things to be learned from all kinds of dementias. Here is a particularly astounding thing to learn: severe autism does not necessarily mean the sufferer is mentally retarded. This video will shock you into looking beyond the outward appearance of those who cannot communicate and into the soul.
Sometimes I wonder how much like this girl my mother is. How much does she really know about what’s going on around her?
The following describes the knowledge gained by Sharlene in the course of caring for both her parents with Alzheimer’s. It is not necessarily a reflection of my views, but I thought it good to publish the research of someone who has an insider’s view of Alzheimer’s dementia.
Sharlene Spalding is a naturopathic consultant in the village of Casco, ME. She is a former primary caregiver for two parents with AD. She holds a master’s degree in natural wellness. Sharlene is an excellent resource in natural healing and a hound dog when it comes to research. Because of what she knows now, she is committed to a pharmaceutical-free home that revolves around organic foods and herbs. You can visit her website at The Village Naturopath.
Now that’s what I mean. You read something about Alzheimer’s, and all of a sudden you see evidence everywhere that you’ve got it and that your life is over.
I’ve avoided reading Still Alice for years precisely because I knew it would send me reeling with the truth of my own “probable” early-onset Alzheimer’s. But I did finally pick it up, and, sure enough, suffered a major breakdown right about chapter three. Yikes! I do have it. Just like Alice, I forgot I was supposed to work on Friday, and when my sister called to remind me, I crumbled. It’s not just that I forgot. It’s that I forgot and didn’t have that nagging feeling telling me that I was forgetting something eating away at me. It was the peaceful forgetting that terrified me. Surely this doesn’t happen to a person unless they have Alzheimer’s. Ever. Right?
Is this forgetting normal or something more sinister? Is it stress from caring for Mom with Alzheimer’s and Dad with Parkinson’s (with a touch of menopause for me), or am I following in my mother’s footsteps?
The lucky thing for me is that I don’t have medical insurance–which means I can’t go to a doctor for a diagnosis. I say I’m lucky because, as we all know, it’s not so much the disease that hurts people, it’s the diagnosis. And it’s not just any diagnosis. Cancer, people rally around you. Alzheimer’s or any kind of mental illness, and the room empties out.
Shoot, you can have the disease for years, but as soon as you get diagnosed, that’s when the tazing starts. People just automatically take out their stigma-tazers and start shooting. And they think they have it set on stun, but really those stigma-tazers are always set on kill.
So my question is, what do you do when you read or hear about terrifying conditions to keep yourself from assuming yourself into that condition and absorbing the fear that is often marketed with it? How do you “keep your head, when all about are losing theirs”? (Kippling)
And once you’re diagnosed, how do you overcome all that tazing?
Chuck’s blog on early onset Alzheimer’s is, I think, a courageous way of dealing with one such diagnosis.
What is your way of dealing with the fear of Alzheimer’s–whether it’s diagnosed or imagined?
If you’re like me and need a visual representation of the brain’s anatomy to understand Alzheimer’s and Parkinson’s research better, here are a few good slide shows and videos for your educational pleasure:
How The Brain Works
From the Mayo Clinic. This is a good starter slide show of the brain’s main functions. In eight slides you get a basic outline of the lobes of the brain and their purposes.
Dementia Pictures Slideshow: Disorders of the Brain
From MedicineNet. These 31 slides show what happens to the brain in cortical, subcortical, progressive, primary, and secondary dementias.
From the Alzheimer’s Association. In 17 slides you will learn about the brain’s basic functions, then how the brain is affected in Alzheimer’s by amyloid beta plaques and tau tangles.
Zoom In and Search for a Cure
From Emergent Universe. This is a fun, artsy, and very interactive show depicting what happens in the brain affected by Alzheimer’s Disease. Among other things, you will discover why ab42 is more toxic than ab40.
Inside the Brain: Unraveling the Mystery of Alzheimer’s Disease
This is a video put out by several government organizations (the NIH, NIA…) showing the pathology of Alzheimer’s in the brain.
The Secret Life of the Brain
From PBS. Here are three interactive shows (requires Shockwave), including, History of the Brain, 3-D Brain Anatomy, Mind Illusions, and Scanning the Brain.
Brain Rules: Sleep
Now that findings show beta amyloid buildup is cleared during sleep, this slide show will be of special interest, as it shows the role of sleep in brain function.
