A call for mainstreaming people with Alzheimer's; 'what's the harm in that?'

As soon as a person is diagnosed with dementia, friends often disappear--even quite early on when the person is just a bit forgetful.

"They think it might all be a bit too awkward," Julian Hughes says of the friends.

"But attitudes must change. Those friends can adjust, let the conversation go with the flow, accept the person with dementia may be living within a few minutes of experience, so you may have to repeat your stories. But what's the harm in that? If they are enjoying it, then it's still a meaningful experience."

Hughes is a British psychiatrist who specializes in aging--his academic interest is the notion of personhood--and recently he spoke throughout Australia, calling for mainstreaming of those with Alzheimer's and other dementias and for governments to recognize this significant health issue. He also made the point that research funding for Alzheimer's lags hugely behind other areas, such as cancer. "As the numbers (of diagnosed) rise, funding will need to increase by a factor of six to eight times to keep pace," Hughes points out.

Dementia is the third-leading cause of death in Australia, behind heart disease and stroke. About 257,000 Australians have dementia today, and that's expected to rise to more than a million by 2050.

In America, deaths from Alzheimer's disease are almost equal to those from diabetes, and both rank below heart disease, cancer, respiratory disorders and accidents. But that's expected to change in the coming years, as Baby Boomers begin hitting age 65. Today, 5.1 million Americans have Alzheimer's disease; that number will climb to 13.5 million by 2050, says a report from the Alzheimer's Association, which says the costs of care will inevitably rise, too, from $172 million today to more than $1 trillion by 2050.

Apple juice found helpful for those with Alzheimer's disease

Behavioral and psychotic symptoms related to dementia seem to improve when people with moderate-to-late stage Alzheimer's disease regularly drink apple juice.

That's what researchers from the University of Massachusetts found in a study published in the June 2010 issue of American Journal of Alzheimer's Disease and Other Dementias.

For their study, the researchers assigned 21 individuals with moderate to severe Alzheimer's disease to drink a 4-oz glass of apple juice twice a day for one month.

Though caregivers reported reduction in anxiety, agitation and delusion, the individuals with dementia showed no changes in the Dementia Rating Scale.

Previous studies have suggested that apple juice may provide health benefits including reduction of central nervous system oxidative damage, suppression of Alzhiemer's symptoms, improved cognitive performance and more organized synaptic signaling. Thomas Shea says other researchers have shown similar effects with blueberries. "We have also shown similar effects with purified vitamins and nutriceuticals." Shea is professor of biological sciences and Director of the Center for Cellular Neurobiology & Neurodegeneration Research at Massachusetts.

Would apple juice be helpful in people with other dementias?

"We saw in mice that apple juice boosted neurotransmitter production, so it might help us all with mood, and the major effect would be seen on those individuals, disease or not, that had behavioral issues," he says. "However, it is certainly worth a try."

Shea says he would like to compare apple juice with apple cider in another study because "cider has the potential benefit of being fresher, and less processed."

Donate for Memory Walk through DementiAwareness, get your loved one on this blog

While I'd love to have a huge group of people walking together at Long Branch Park Oct. 2 for the Alzheimer's Association's Memory Walk, I know that life sometimes gets in the way!

If you'd like to join us, but can't, let DementiAwareness walk in honor or memory of your loved one. Make a donation of $50 or more through our team, and we'll post your loved one's photo on this blog through the end of October. (See my example at left.)

Now, if this recession is hitting you like it's hitting me, you may appreciate this reminder: participation in the Memory Walk is free. You can raise awareness regarding Alzheimer's and other dementias just by showing up--and that costs only your time.

Honoring Dads who are being stolen by dementias

Since I really could not have said it better myself, I'm turning my blog over to Loren B. Shook in honor of Father's Day. He is president and chief executive officer of Silverado Senior Living. My Dad residents in one of Silverado's 34 facilities. Here's Mr. Shook:

All of us fortunate enough to grow up with loving fathers are who we are today thanks to the lessons they taught us. Whether it was how to fish, ride a bike, or throw a baseball, or the values of hard work, integrity, kindness and strength, what Dad showed us decades ago remains at our core.

As one who works with the memory-impaired, I believe the growing number of now-elderly fathers whose memories are disordered are teaching us a new kind of lesson. Understanding this lesson can resolve the anguish many of us so-called "adult children" of those with Alzheimer's disease are feeling as Dad's recognition of us and his ability to communicate slip away.

It's the lesson of selfless love.

Time and again, I hear the same question from sons and daughters: "Why should I visit Dad if he doesn't know who I am and if he won't remember I was there?" Written out, it sounds shocking, but when spoken, it's always tinged with profound sorrow and hurt. It's understandable. When a father is so much a part of your own being, who are you if he no longer knows you?

My answer is always this: Your father needs you now more than ever, and what he needs from you is simpler than ever, too. Because the greatest pleasure you can give your father now is the gift of your time and your presence. You see, the worst pain suffered by the memory-impaired comes from their sense of loneliness and worthlessness. Just as you may feel that your father's condition has come between the two of you, he feels increasingly isolated from the world and from the things that have always mattered. It's no wonder that depression goes hand-in-hand with memory impairment, and sadly, it further aggravates health, both emotionally and physically.

While your dad might no longer realize who you are or greet you by name, it's more important than ever for you to spend time with him. Just being at his side brings him greater joy than you can likely even imagine. He may not be able to express this pleasure in a way that you understand, or that the world at large comprehends, but without a doubt, he feels it and he feels that he is loved. In this way, you are nourishing his spirit, and the value of this is indescribable.

So I encourage you to take the occasion on Father's Day to honor your dad in this way. Whether he resides in a senior care community or is receiving care in his own home, visit him and stay by his side for a while. Even if you can't have the kind of conversation you used to have, there are still ways to make the time together meaningful.

The great thing is that they're simple. If he has always loved a certain kind of music, bring a CD of it and listen to it with him. Those fishing trips and baseball games Dad took you to when you were a child? If you have pictures of them, go through them. Long-term memories are more durable than short-term in the memory-impaired, and I am certain he will enjoy looking through those photos with you. Even a box of candies that he has always fancied can brighten his day.

Yes, I know, after you leave you will have no assurance that he will remember that you were there.

But understand that it doesn't matter.

What matters is that during the time you spent with him, he knew he was loved, and that intangible emotion will definitely have a lasting positive impact on him.

The longer that I work with those with memory-impairment, the more clearly I understand the importance of something that I once heard: that it's when you give a gift selflessly that you will get the most in return. When you give your love selflessly to your father, not only will he benefit, but you will, too. You strengthen his spirit and your own.

So you see, your dad is still teaching all of us a very important lesson.

Thank you, Mr. Shook.

Make a $250 Memory Walk donation, and your busienss gets an ad on this blog

If your company makes a donation of at least $250 to the Alzheimer's Association 2010 Memory Walk through my DementiAwareness team, here's the deal: I'll give your company an ad on my blog from now to the end of the year -- free.

This is the primary fundraiser for the Alzheiemer's Association, with a series of Memory Walks taking place throughout the country. Ours here in the Syracuse area is a 3-mile walk starting at 9:30 a.m. Saturday, Oct. 2, at Long Branch Park.

I'm honored to be asked to serve as honorary chair.

If you don't know someone with Alzheiemer's disease or another dementia, or someone caring for a person who is afflicted, chances are very good that you will in your lifetime. And more than one.

A growing number of people are dealing with a dementia, either as patients or caregivers. More than 5.3 million Americans have Alzheimer's, which is thought to only represent 60 to 80 percent of all dementias. It's a disease that affects primarily older people. And with the first of the Baby Boomers turning 65 in 2011, many health experts are saying we are not adequately prepared.

One of my roles as honorary chair of the Memory Walk is to make sure businesses understand the impact this disease has on their workers. It's profound. Sure, there are signs and symptoms of Alzheimer's, but often it sneaks up before a family realizes their matriarch or patriarch is so afflicted. One day, a dutiful daughter is a hard-charging career woman, and the next, she's struggling to take the car keys away. Caregivers are thrust into a role that is, quite simply, overwhelming. The stress is constant and can be debilitating. (Read more of my blog for multiple posts by and about caregiver issues.)

This disease is not just a personal medical issue. It is already making a huge impact on our nation's health care system and the insurance industry--the cost of the disease is estimated at $20.4 trillion over the next 40 years, by the way. Businesses large and small are impacted not only in increasing health costs, but in worker absenteeism when one must care for a loved one.

Donations to the Alzheimer's Association go toward care, support and research. Dollars raised at the Syracuse Memory Walk stay right here in Central New York. Remember, if you donate through DementiAwareness, I'll put your ad on my blog through the end of the year. (The sooner you donate, the longer your ad appears!)

Finding a link between PTSD and dementia raises the question of why

Male military veterans with PTSD were found to have a nearly 2-fold-higher risk of developing dementia, compared to those without post-traumatic stress disorder, an anxiety disorder that is highly prevalent because of combat. Results of a study into this link are published in this month's Archives of General Psychiatry.

The study involved 181,093 veterans 55 years or older without dementia from 1997 through 2000. Between 2000 and 2007, researchers discovered 17 percent of the men developed dementia, according to the abstract by Dr. Kristine Yaffe and colleagues at the University of California, San Francisco, and San Francisco Veterans Affairs Medical Center. They presented their work last year in Vienna at the International Conference on Alzheimer's Disease.

"Mechanisms linking these important disorders need to be identified with the hope of finding ways to reduce the increased risk of dementia associated with PTSD," they write. Some theories: that PTSD contributes to the cause of dementia, that chronic stress plays a role, or that stress damages the hippocampus or cause alterations in neurotransmitter and hormone levels that could precipitate dementia.

Finding a link between PTSD and dementia was not entirely surprising. "We already know that traumatic brain injury and certainly chronic stress increase the risk of cognitive decline and what this paper refers to as 'accelerated aging,' which may in turn lead to early dementia. So it makes sense that PTSD would increase the risk for dementia in the long run," Maria C. Carrillo, a senior director for the Alzheimer's Association, told Medscape.

New York's new 'gold alert' is like 'Amber alert' for adults with dementia

New York has a new "gold alert" alert system for vulnerable and elderly adults, with passage by the Senate of legislation sponsored by Senator David J. Valesky (D-Oneida.)

“Too many lives have been lost as a result of adults with cognitive impairment wandering from home,” the senator says in a news release. “The Gold Alert puts their safety, and the peace of mind of their families, at the forefront.”

Searching for lost adults with dementia is nothing like searching for lost children.

The legislation builds on the existing statewide Amber Alert system used by law enforcement to alert the public to missing children.

The Alzheimer’s Association says more than 60 percent of people with dementia will wander away from home at some point. Studies have shown that 50 percent of those who are not found within 24 hours are at serious risk for injury or death.

In order to prepare local officers for gold alerts, the new program will develop training for law enforcement that helps investigators identify and manage cognitively disabled adults. In addition it creates a toll-free 24-hour hotline that residents can use to report a missing loved one.


Read about the legislation, which included other quality of life measures for seniors.

Locating genes for clues to Alzheimer's risk, cause, diagnosis


Neuroscientists have zeroed in on some target genes that may be tied to the development of Alzheimer's disease, and they've shown what abnormalities appear on brain scans of people with these genetic variations.

Both bits of scientific progress are incremental steps toward understanding what causes the disease that afflicts more than 5 millon Americans. The study, lead by researchers in Boston and Cambridge, Mass., England and Wales, appears in this month's Archives of Neurology.

"The drought of genetic findings in Alzheimer's disease has lasted a long time," write scientists based in London and Wales in an editorial accompanying the Archives study. "These findings, and the genome-wide studies that presaged them, mark a new period of optimism for those of us who study the etiologies of complex diseases of the nervous system."

The study explains the association researchers made between genetic loci that are related to Alzheimer's disease and neuorimaging measures that are related to disease risk. (These measures include the volume of the hippocampus, amygdala and other brain structures.) They identify B1N1 and CNTN5 as additional specific locations of genetic variants on chromosomes, but say their findings warrant further study.

Just one genetic variant, known as APOE, has been shown to influence Alzheiemer's disease risk and age at onset, lead authors Drs. Alessandro Biffi and Christopher Anderson write in their background information.

Study participants included 168 people with probable Alzheimer's, 357 people with mild cognitive impairment, a precursor to Alzheimer's, and 215 people who were cognitively normal. "Our results indicate that APOE and other previously validated loci for Alzheimer's disease affect clinical diagnosis of Alzheimer's disease and neuroimaging measures associated with the disease," they write.

Will that bring us closer to genetic tests for Alzheimer's?

Somewhat, John Hardy, of the University College London Institute of Neurology, says in an email, "but I think this genetic determinism argument is oversold, frankly.

"About 5 percent of the population are at high risk. About 30 percent of the population are at a moderate risk, and about 65 percent are at lower risk. These numbers are little changed by the new data. And, this is not really so useful for genetic testing."

What is it like to have dementia?

What's it like for Dad, I've often wondered. Is he frustrated, trapped in a body with a malfunctioning mind? Does he understand that he is deteriorating? Did he, at the beginning?

Would I know, at the beginning, if I were to develop Alzheimer's? I don't want to suffer with a dementia; could I create a way out for myself now, in the event I lose my mind later?

That was one of the main character's thoughts in Lisa Genova's heartbreaking/inspiring/terrifying novel, "Still Alice." A neuroscientist, Alice Howland develops early-onset Alzheimer's disease. (The paperback, published by Pocket Books, sells for $15.)

It's a compelling question: What is it like to have dementia?

So when I got an email from WebMD with that subject line, I had to read more.

Writer R. Morgan Griffin does a good job of explaining how caregivers help themselves, and their loved one, by understanding what the disease is like for the person who has it. An excerpt:


Some people think of memory loss superficially, as merely forgetting words or names. But it’s much more profound than that. Everything we do is premised on memory. When you walk into the kitchen to make dinner, your actions are almost unconscious. You grab food from the fridge, turn on the oven, take out plates and silverware – your memories are a foundation, and they give you a context for what you’re supposed to do in a given situation.

For a person with dementia, that context is ripped away. A woman with Alzheimer’s disease may walk into a kitchen and have no idea why she’s there or what she’s supposed to be doing. She might still be able to make dinner – especially in the early stages of the disease – but it’s a struggle. Each step has to be reasoned out and thought through. That’s why people with dementia tend to act more slowly than they once did.


The rest of the article is full of additional observations and explanations. Read it, and you'll find yourself saying, "so that's why my Mom does..." or "that explains why Dad did..."

Understanding dementia from a patient's point of view can make caregiving less frustrating. Knowing the patient personally is important, too.

We fretted over how to convince Dad that he needed to live in a memory care facility. Stubborn and independent, he was unlikely to admit he needed help, that it was for his safety. Tell him he had dementia and he'd appear quietly stunned--and you could not tell if he was processing the information, angry about it, or considering what those words meant. But he was still Dad.

The facility we were considering, Silverado, had a calendar of events planned for the residents, and one of the outings was to the State Fair of Texas. Since Dad had run the midway there for years, we figured that would be an ideal day for Dad to visit Silverado. He knew Silverado was for people with various types of dementia, and he knew the residents would need help getting around the fairgrounds. He found a purpose in acting as their guide. Soon he began believing Silverado was where he worked--he returned home in the evenings to sleep at first--and the staff kept him busy stuffing envelopes and such. When I'd call, he answered the phone as he always had answered his work phone: "Cleveland Smith, may I help you?"

It broke my heart. But, I recognized Dad had found a way to cope with his diagnosis. So had we. We joined reality with his reality, and together we were understanding what it is like to have dementia.

Cases of doggy dementia go undiagnosed

Dogs get dementia, too.

It's called canine cognitive dysfunction.

And it's especially interesting, from a research point of view, because canine brains more closely resemble human brains than those of laboratory rats. Also, since so so many dogs are members of human families, they are subject to many of the same environmental factors as humans.

Most senior-age dogs with dementia go undiagnosed, according to a recent study in The Veterinary Journal. Veterinary scientists at the University of Sydney studied 1,000 dogs and found 14 perent had dementia. Only about 2 percent had been diagnosed. (Researchers found no appreciative difference among breeds, by the way.)

''Like dementia in humans, canine dementia often ruins the bond between the sufferer and their carer because the dog no longer seems to recognise the owner or may develop annoying habits,'' Hannah Salvin, a doctoral student at the university who led the study, told the Sydney Morning Herald.

As with humans, the disease is incurable.

Some treatments are emerging, though, and associate professor Paul McGreevy told the newspaper "their responses could provide us with pivotal information about the potential therapeutic effects in humans.''

Salvin and McGreevy are interested in studying more dogs in the greater Sydney area. Their website, maturedogs.com, provides details.

Symptoms

Pacing, circling, wandering.

Failure to recognise familiar people or pets.

Walking into walls or furniture.

Standing over water bowl, not drinking.

Avoiding being petted or touched.

House soiling.

Lynn Lazarus Serper brings 'Serper Method' to Syracuse

Lynn Lazarus Serper--involved in groundbreaking work on learning programs to maintain and improve brain health and vitality--presents "The Serper Method" with communication strategies and learning activities at a conference in Syracuse June 10 and 11.

Her appearance is part of Upstate Medical University's 22nd annual Alzheimer's Conference, designed for families, caregivers and health care professionals who care for people with Alzheimer's or other forms of dementia.

Registration for both days is $95 for caregivers, $115 for health care professionals and $140 for doctors.

The words my heart cannot express

I'm not someone who cries. Well, at least not unnecessarily.

Maybe I lost that propensity through paramedic training, an unspoken lesson in developing professional demeanor. Maybe the cynicism of a career in the news business did this to me. At any rate, it's unusual for me to cry.

But lately, unexpectedly, my eyes will fill with tears. I do not need to be thinking of my Dad for this to happen, though the tears immediately remind me of him and his existence/life at his memory care facility. I miss him so much, though he is not entirely gone. He is slipping away or fading, as I've heard it called. I say he is stuck between the here and the hereafter.

It was October 2008 when I toured the facility where he would move a few weeks later. The administrator was kind enough and spoke knowledgeably about long term care. He showed us around. Silverado's single-floor building was designed to allow for wandering safely. At meal times, residents could exit their rooms and turn left or right and either way, the hallway would eventually feed them into the dining room. Outdoors, the pathway terrain alternated from pavement to gravel, giving residents the perception of traveling further than reality. There were spots for gardening, a cage full of parakeets and canaries, a juke box, and, best of all, dogs who lived there.

The tour began to feel a little like the tours of day care centers I'd taken not too many years before when my children were babies. Directors of day cares similarly touted their centers' features, policies and various activities.

The Silverado administrator let us peek at some rooms, and then he pointed out the memory cases on the walls outside of each resident's room. These were glass-enclosed shelves similar to shadow boxes, but bigger, and they reminded me of the cubby space at daycare that parents are invited to personalize with photographs and mementos.

Before I knew what was happening, I was sobbing, crushed by the thought of the memory case that would be my Dad's. He was 68 years old. How were we supposed to boil his life down to three shelves?

I cried, but I quickly composed myself. Just as I do now whenever my eyes start watering.

"There is a sacredness in tears.
They are not the mark of weakness, but of power.
They speak more eloquently than ten thousand tongues.
They are messengers of overwhelming grief...and unspeakable love.”
--Washington Irving

Research into cognition explains some age-related memory loss

You really can't teach an old dog new tricks. Well, not if you expect the dog to remember the trick.

Through research into cognitive decline, scientists have demonstrated that "there is a biological reason why people cannot learn new things at an older age, but can retain knowledge learned years before," says John Morrison, dean of basic sciences and the graduate school of biological sciences at Mount Sinai School of Medicine.

Certain types of specializations on nerve cells called "spines" are depleted as someone ages, causing cognitive decline in the part of the brain mediating the highest levels of learning, he explains in a study published June 2 in the Journal of Neuroscience.

We lose certain spines as we age, but this study explains which ones and how their loss impacts cognition--which may lead scientists to develop new therapies that target age-related cognitive decline.

The research team studied six young adult and nine older rhesus monkeys as they participated in a delayed response test. The monkeys watched as food was baited and hidden. Then a screen was put in front of them so they could no longer see the location of the hidden reward. At the beginning of the test, the screen was raised immediately, and the monkeys found the reward right away. The memory of the monkeys was tested by increasing the time the reward was blocked from view. The aged monkeys performed significantly worse on the tests than young monkeys, especially as the time intervals increased, researchers reported.

They then studied the microscopic changes in the nerve cells within the prefrontal cortex, an area of the brain that mediates high level learning. Nerve cells in this area contain both thin, dynamic spines which are key to learning new things, as well as large, mushroom-shaped spines that likely mediate long-term memories and expertise. The older monkeys lacked the thin spines but retained the larger spines, "indicating that the loss of the thin spines may be responsible for monkeys' inability to learn and retain information during the test," says a news release from Mount Sinai.

An extended family, a photographer's studio and a camera


We gathered for what we knew would be our last formal family portraits. It was Thanksgiving 2008, just after Dad had officially moved into a memory care facility. His wife, two children and six grandchildren donned clothing in matching shades of navy and khaki and directed him into a photographer's studio.

Dad was in decent spirits that day. He would generally sit where he was asked and smile when he was told. In the midst of the sitting, my then 11-year-old son held my point-and-shoot camera--and snapped this photo of his Grandpa.

It became my favorite after my son explained why he took it: because Grandpa looked as if he was looking for something and didn't know what.

A curious study of Agatha Christie and Alzheimer's -- and how our writings may one day be used for diagnosis


The language of people with Alzheimer's disease includes significantly more indefinite words and repetitions than the language of healthy people of similar age and level of education.

So, an English professor at the University of Toronto, Ian Lancashire, analyzed the writing of British mystery writer Agatha Christie.

Previously, the works of British novelist Iris Murdoch were analyzed for signs of the Alzheimer’s disease that was confirmed after her death. Science Blog reported in 2004 that "while the structure and grammar of Murdoch's writing remained roughly consistent throughout her career, her vocabulary had dwindled and her language simplified in her very last novel."

Christie was never diagnosed with Alzheimer's. She continued to write in her final years, though some people believed she suffered from dementia.

Lancashire says her 73rd book, "Elephants Can Remember" is universally dismissed by critics as being full of errors and poorly plotted. The main character is a female novelist who struggles with memory loss while trying to solve a crime that happened in the past.

The professor told National Public Radio that when he read the book, he felt Christie was sensing what was happening to her, and that she kept writing "struck me as heroic."

His study involved feeding the text of 16 of her novels into a computer program that analyzed the vocabulary for the frequency of different words and the number of different words in each novel. "The richness of the vocabulary of Christie’s novels declines with her age at composition. The three novels that she wrote in her 80s, (Nemesis, Elephants, and Postern of Fate,) have a smaller vocabulary than any of the analyzed works written by her between ages 28 to 63," he writes.

Christie was 81 when she wrote the Elephants novel. Her use spiked of what Lancashire called indefinite words--"thing," "anything," "something," "nothing." At the same time, the number of different words Christie used dropped by 20 percent. "That is astounding," Lancashire told NPR. "That is one-fifth of her vocabulary lost."

Most of us don't have large collections of writing done over the course of our lives. But Lancashire points out in his conclusion that "this will begin to change as more individuals begin to keep, if only by inertia, a lifetime archive of e-mail, blogs, professional documents, and the like.

"While the diversity of topics and genres in such an archive brings methodological problems to the analysis ... we can nonetheless foresee the possibility of automated textual analysis as a part of the early diagnosis of Alzheimer’s disease and similar dementias."

What's in a name?

Both my first-born and my brother's first-born children have the same middle name as their grandfather: Cleveland.

It's an old family name.

A paternal uncle with a few "greats" before his name was Grover Cleveland, who was the 22nd and 24th president of the United States. He died just over 100 years ago, in 1908. He spent part of his boyhood growing up in Fayetteville, NY, and I drive by Academy Street where his former home still stands almost every day.

Look at the pictures of Cleveland, the president, and compare the stately way with which he holds his head with the looks of Cleveland, my Dad in this picture taken at Silverado Senior Living where he has lived since October 2008.

President Cleveland was a lawyer and a long-time bachelor. He served as mayor of Buffalo and governor of New York before becoming president, and so far he is the only president to serve two nonconsecutive terms. Historians say he was known for his laser-sharp focus, and they say he was at first ill at ease with the niceties of life in the White House. He's described as "honest, fearless and hard working," in the 2006 Scholastic children's book, "Grover Cleveland."

One of the many Grover Cleveland biographies says much about the man with its title, "Grover Cleveland: A Study in Character," by Alyn Brodsky. The book quotes another biographer who calls Cleveland a paradigm of honesty, integrity and resolution who acheived greatness through strength of character; a man who, though flawed, exemplified "courage that never yields an inch in the cause of truth, and that never surrenders an iota of principle to expediency."

Of course, strength of character isn't necessarily handed down through generations, though I'd like to think it is. And I realize that many people hold their bodies square and firm for portraits, making them no more or less "stately" than either Cleveland. Still, I like to think we can trace some traits through our lineage.

Is/was my Dad honest and hard working and principled because his namesake was? Have my son and nephew inherited those traits, too? Sometimes I fret about what their genes hold: the same frontotemporal dementia that afflicts my Dad? Or something benign, like fearlessness or laser-sharp focus, even an aptitude for the law?

Factors that may increase risk

Four factors are associated with an increased risk for Alzheimer's disease and cognitive decline. They are not necessarily causes, but science has noticed some meaningful connection between these things and an increased risk for Alzheimer's and cognitive decline. They are:
* diabetes,
* the gene variation ApoE,
* current smoking, and
* depression.

Evidence is not as strong for a connection between estrogens or nonsteroidal anti-inflammatory drugs and an increased risk for Alzheimer's, and there's no evidence of a connection between estrogens or NSAIDS and cognitive decline.

There is also not a consistent association involving cholesterol-lowering medicine, obesity, high blood pressure or blood homocysteine levels for either Alzheimer's or cognitive decline.



state-of-the-science conference statement

Factors that may decrease risk

Three factors are associated with a decreased risk for Alzheimer's disease and cognitive decline. These are not necessarily causes, but meaningful connections. They are:
* cognitive engagement, through literacy and social enrichment,
* physical activity later in life, and
