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

As near as I can figure, these are the five stages of elder caregiving that correspond to the Kubler-Ross states of grief:

1. DELUSION. This is where you have boundless energy and think two lives are possible: one with you as caregiver, and one with you as successful entrepreneur.

2. FRUSTRATION. This is where you realize you have been delusional and have to make a choice between the two yous. The results are tress and guilt. Stress because your intentions are still lofty, but your body is getting tired. And guilt because you know you have to give up your own agenda, but want to keep it.

3. ANGER. This stage starts with resentment. You may start thinking part of what’s going on is on purpose—that your loved one is intentionally “pretending” some of the sickness. Or you think they’re not trying hard enough to cooperate with your care. You are in constant correction mode here, and getting angrier because your [barely] loved one keeps repeating the same frustrating behaviors (see Elder Rage).

4. DESPAIR. You finally get it that it’s not their fault. You accept that the disease is controlling your loved one and getting worse. You stop blaming them, and instead heap all the blame on yourself because you still think you ought to gain control over this caregiving business but can’t. Along with despair you have increased guilt and exhaustion.

5. RELEASE. In this stage you finally give up control. You realize you cannot do this entirely by yourself. You delegate care (maybe for a day or two of day care, maybe institutionalization). The result is considerably less stress; even joy; and certainly wisdom.

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?

This week I started wearing the monovision contact lens that I got three years ago. This is the lens that you wear in one eye to correct for reading while leaving the other eye free to focus on things in the distance.
I tried this lens years ago but found it unacceptable. Everything was at once blurry and sharp, and I couldn’t tolerate the tiniest bit of blur in my vision.
I realized it was a mental adjustment—I would have to learn to choose the sharpness of one eye over the blurriness of the other at any distance until all I saw was sharpness. But I was impatient and gave up on the adjustment period, resorting instead to donning and doffing reading glasses when in need.
Now my close-up vision has gotten so bad that when I tried the monovision lens this time, my mind was quite happy to accept the gift of semi-sharpness without the need to scout around for glasses. It took a very short time, in fact, for my brain to adjust and see all things in focus at all distances.
Remarkable how the brain can do that.
I learned a similar lesson in life with the attitude of gratitude. I was going through a very stressful, heart-rending period when nothing seemed to be “working” for me. One day I plopped down on the floor and began to say “thank you” for every part of my life. It was a turning point in my stress level. I began to see not problems but challenges; not curses but blessings. And what a difference it made!
Alzheimer’s and other devastating diseases, I’m noticing, can be lenses that change the way we see life; they change what we think is important; they bring into focal clarity the gift of family, friends, community, connection. I’m amazed as I surf the blogs written by sufferers and caregivers to see the softness that takes over when anger ends. I’m amazed, for example, with Michael J. Fox’s attitude toward his Parkinson’s, calling it a “liberating” gift. I’m touched by the may bloggers who share of the immense struggle of caregiving and the eventual gratitude it produces in them.
It’s always a choice the person makes to see disease differently. Or rather, to see the value of the person despite the disease.
In this season of Thanksgiving, it is good to see the change that Alzheimer’s and other diseases have brought to our self-centered culture.
So, thank you to all of you who write and share of your struggles, forming a new community that chooses to rise above bitterness and embrace even the bleakest, darkest days of life for the goodness they produce.

Here’s a fascinating animation superimposed over a lecture by psychiatrist and writer Iain McGilchrist on the two hemispheres of the brain. You may have to watch it 15 times to really get it.

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 even as he battles the attachment he has to that self.
In this book, Helmut Dubiel analyses his response to the personal and social implications of his Parkinson’s disease. He does not blame or excuse. Rather, he tries to put his and other’s reactions in context of the overarching laws of social interaction.
There is pain in this book. There are lies and pity and anger and judgment. But mostly, there is acceptance of the facts of disease and an acknowledgement of man’s irrepressible will to live and to thrive.

Yesterday as I read this book to Dad, I noticed him fidgeting more than usual. I stopped and asked him what was the matter. He said, “It seems like you’re reading about me.” I explained that this was a philosophy professor writing about himself. Dad calmed back down and listened with interest. Dad doesn’t talk about his inner battles much, so this would logically be painful for him. But good. I think this was one of Professor Dubiel’s hopes-that through his honest self-examination, others would feel released from the need to hide from their disease and, in so doing, find relief.

I’ve often asked people, “Which would you prefer: to lose your body or to lose your mind?” Given that I live with one parent with Alzheimer’s and the other with Parkinson’s, this question has personal weight. In his book, Professor Dubiel clearly expresses his preference for holding onto the self despite the ostracism brought on by the physical distortions of Parkinson’s. Knowing you are being unfairly rejected is still preferable to knowing nothing at all. On the other side, in Still Alice the protagonist affirms this appreciation for the self when-in a lucid moment-she acknowledges “I didn’t meant to get this way. I miss myself.” The mind is a far greater gift than the body.

Of course, in the end, Parkinson’s takes the mind as well.

My take-away? Pray for a cure for both diseases; forgive my and others’ shortcomings; enjoy today.

I found this short documentary film yesterday while browsing another blog about Alzheimer’s. It’s in French with English subtitles and you can watch it for one euro online. Worth the euro and then some (you can click on the picture to go to the website). The film is done by the son of an artist with Alzheimer’s, and the documentary marries his own artistic and filial sensitivity well.
As an artist whose artistic mother also has Alzheimer’s, this movie hit home for me. It was like watching my own mother lose all her nouns, then her knowledge of interpreting nouns on a canvas, and finally her knowledge of self.
In this film, the mother’s sorrow and fear are mitigated by the son’s desire to hang out with her. I only hope his desire lasted beyond the making of the film. For the sake of all those with Alzheimer’s, I hope love lasts beyond the time the disease is an interesting artistic or scientific curiosity. I hope it lasts beyond the time a diseased person has anything at all to offer.

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.

Another thing I got from Oliver Sacks’ book was a new notion of the power of music in dealing with dementia. My previous post on music and Alzheimer’s dealt exclusively with the notion of music as a memory stimulant. But Sacks’ book made me realize that music can be used as a tool to organize thought and action in the present—in the midst of neurological damage.

Yesterday as I lay down for a recuperative nap, I listened to a Scarlatti sonata in the background, and immediately got a visual sense of what goes on in the brain when music is played. The first picture that came to mind was an animation of DNA transcription: that funny little zipper head that makes a perfect copy of your DNA as it unzips the double helix. Nibble, nibble, nibble, copy, copy, copy. Then I saw Scarlatti’s sonata as doing the opposite with my thoughts: grabbing all the randomness in my mind and knitting it into a useful strand, or, if you want to be more esoteric, turning it into functional narrative.

In Sacks’ The Man Who Mistook His Wife for a Hat, the first clinical case is of a man who had lost all “sense of familiarity:” he could not recognize faces, body parts, food, clothing. Sacks wondered how the man (also a music professor) could function with this neurological deficit, so he went to visit him in his own home. It turned out the man had a very musical brain, and he functioned by humming a tune as he went about his daily business. He could eat as long as he sang, but if interrupted, would no longer recognize his food and would stop eating. He could dress by the same means. His wife would set out his clothes for the day, and he would only recognize them as clothes and dress himself once he started singing! His musical brain was compensating for his lost sense of recognition.

And now I remember a funny little entry by Bob Demarco on the Alzheimer’s Reading Room that is seriously brilliant. He talks about using music to stimulate his mother into action:

My sister was shocked when I told her on the phone that I finally “convinced” my mother to drink prune juice after years of trying and failure. Joanne was here and saw my mother refusing to drink and calling the prune juice poison. It was only after I introduced the “prune juice song” that my mother starting drinking the juice every day and the dreaded Poop-E problem was solved.
I also have the pee song, the poop song, and a long list of songs soon to be number one hits.

This is exactly what Oliver Sacks would have recommended! Music and Alzheimer’s (and Parkinson’s and most other dementias): stimulating the mind into action.

I’ve had water on my mind lately (which is not the same as, but does not preclude, water on the brain).
Anyway, ever since my sister-in-law’s mother was taken to the doctor with signs of Alzheimer’s and discovered to have nothing but dehydration, I’ve been meaning to read up on how exactly the lack of water hinders brain function.

Here’s what I found about dehydration and the aging brain:
Not much—unless you count articles on websites trying to sell water filtration systems.
The fact that water makes up 70-80% of a nerve cell and transports both nutrients and wastes from neurons means it is essential for proper brain function all through life. That’s a given. What’s not a given is how much a brain has to be depleted of water to affect cognition.
Rigorous research on the topic of the brain and dehydration is limited. Even the “standard facts” about the body and water are all over the place: babies come out of the womb composed of 90% water; no, 78%; no, make that 70%. In adults, the proportion is 60% water for males and 55% for females. The consensus is 50-60% for adults in general. The brain is 60% water; nay, 90%. Whatever.
As for how much water you need to drink on a daily basis to be properly hydrated, oy, there is no consensus. For years I’ve been hearing “8 cups a day.” No allowance for a sedentary life or for someone with a diet of fruits and vegetables (which are high in water content); no penalty for eating junk food (which would increase the need for the detoxifying properties of water) or for spending days cooped up near a wood stove.
One article quoted the Mayo Clinic as saying that “the average adult loses more than 80 ounces of water every day through sweating, breathing, and eliminating wastes,” and therefore you’d have to drink 10 cups of water/day to rehydrate. I searched for the quote on the Mayo Clinic site and didn’t find it. Instead, I found a recommendation for 6-8 cups of water per day.
Suppose you take the most conservative recommendation of 6 cups per day-do you follow that? I don’t think I’ve ever gone one whole week drinking that much per day.
It has been estimated that 75% of Americans are chronically dehydrated. OK, that figure is questioned. But it seems to be a fairly hard fact that “among people over 65, dehydration is one of the most frequent causes of hospitalization.”* Understandable: throw in a bit of incontinence, and fear of hydration soars. Also, some medications are diuretics, and after 50, the body loses kidney function and is less able to conserve fluids.*
But how bad is dehydration for your brain?
According to Lumosity, when your body lacks water,

brain cells and other neurons shrink and biochemical processes involved in cellular communication slow. A drop of as little as 1 to 2% of fluid levels can result in slower processing speeds, impaired short-term memory, tweaked visual tracking and deficits in attention. With proper hydration however, neurons work best and are capable of reacting faster.

But pinning down the exact link between hydration and cognitive function is tricky in the lab. From Hydration and Human Cognition:

Although adequate hydration is essential for optimal brain function, research addressing relationships between hydration status and human behavior and cognitive function is limited. The few published studies in this area are inconclusive and contradictory. The impact of variations in hydration status, which can be substantial as humans go about their daily activities, on brain function and behavior is not known and may impact quality of life.

From PubMed’s Hydration and Cognition: a Critical Review and Recommendations for Future Research: “The limited literature on the effects of dehydration on human cognitive function is contradictory and inconsistent.” The monkey wrench in research here is given as confounding factors:

Confounding factors, such as caffeine intake and the methods used to produce dehydration, need to be considered in the design and conduct of such studies. Inclusion of a positive control condition, such as alcohol intake, a hypnotic drug, or other treatments known to produce adverse changes in cognitive performance should be included in such studies. To the extent possible, efforts to blind both volunteers and investigators should be an important consideration in study design.

On the Mayo Clinic site, a Dr. Lette finds that “there’s no scientific evidence that drinking large amounts of water is good for one’s health.” The recommendation in this article is to drink when you’re thirsty, and that’s enough.
My question is, does the lack of scientific evidence mean there is no scientific proof or merely that there is no motivation to research the topic to obtain the evidencef? Who, after all, would fund research into water being fundamental to the health of the aging brain? Not the pharmaceutical industry. If you could avoid dementia by being continually hydrated, you wouldn’t need pills to fix dementia. Why would any self-respecting drug company fund that finding? And if it takes a lot of money to work through all the confounding factors, who’s going to pay for it?

The thing is, when the anecdote about my sister-in-law’s mother is not even rare, it makes me wonder how many cases of Alzheimer’s are checked for a history of dehydration. I don’t mean just the over-the-weekend kind of dehydration, but long-term, chronic shortage of water.
As with Mom. The list of things Mom was doing “right” for her aging brain is stellar: she was highly educated, spoke multiple languages, was given to prayer and meditation, was active in the community, etc., etc. Yet she succumbed to complete dementia in her early seventies! Could it all have been due to her severe distaste for water? I mean, she hated water-would gag if she drank it straight from the tap. Could her present dementia have been prevented by a regimen of 4+ cups of plain ole water daily?
I hate to look at the “what if” from Mom’s point of view, but for our generation and beyond, it needs a good deal more consideration than we’re giving it.
What do you think? Am I grasping at straws? (I suppose that’s OK as long as the straw is propped inside a nice glass of water, right?).

Yesterday Bloomberg Businessweek published an article titled Mouse Study Suggests Alzheimer’s-Linked Protein Can Migrate Into Brain.
The story is this: researchers took brain matter from mice that had beta amyloid plaque (were genetically modified to have such plaque), injected it into the stomachs of normal mice, and months later found beta amyloid plaque in the brains of the normal mice.
If all you read is the headline of this story, the conclusion is that the beta amyloid from the sick mice got into the bloodstream of the healthy mice and passed through the blood brain barrier to take up residence in the healthy brains.
But if you read to the end of this article, it is suggested that there could be all kinds of reasons the healthy mice ended up with beta amyloid plaque in their brains, such as maybe there is some chemical in the plaque brain sample that passes through the blood brain barrier and causes a chain reaction that produces beta amyloid plaque—which would negate the headline altogether.
Now, watch the news and see how many people with take only the headline of this story and pass it off as scientific fact.

The moral of the story: be careful what you read and how you read it.

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.

Say, what?

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.

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 capable of shutting down when the mind is concentrating on some difficult cognitive task as it would do in a younger adult’s brain. Since the default network uses 30% more resources than the rest of the brain, you can see how the resources available for cognitively challenging tasks decreases as we age.

In Alzheimer’s, you get the extreme case of this aging effect: the default network doesn’t shut down at all when it’s supposed to (same as in Schizophrenia-which is probably why they use antipsychotic drugs meant for Schizophrenia in Alzheimer’s patients) until that part of the brain eventually dies.

The default network is not very developed in children. It gets more active as we grow into adulthood. That makes me wonder if language is the software that runs the default network. Think about it: the default network is the part of the brain that sorts, categorizes, and edits/deletes memories, and language is the software that sorts, categorizes, and edits/deletes meaning. With language also comes prejudice, and prejudice does not exist in the very young. Also, in Alzheimer’s the default network eventually atrophies, and language ceases (just further argument that the default network is inextricably tied to language).

All of which brings me to the point of this post. Last week there were articles all over the news saying that having more than one language guards you against the worst of Alzheimer’s. Mom spoke four languages and fell prey to Alzheimer’s in her sixties-with no family history of early Alzheimer’s. Dad spoke three
