Will You Get Dementia?

Dear Future Centenarian,

Conventional wisdom dictates that if you live to age 85, you™ll have a 50% chance of having Alzheimer™s by then. And I believed that until now.

You™ve probably see articles and reports from time-to-time that project high medical costs to take care of the increasing numbers of the aged, especially the ever-increasing costs to take care of the millions of projected new Alzheimer™s patients. I saw projections extending to 2050 and beyond.

None of these projections takes into account the exponential rate of growth of medical and aging technologies. Most people assume things will be pretty much the same in the future as they are now. I always discount these kind of projections extending decades in the future as pure nonsense, because they completely ignore the emerging technologies and their impact on turning the tide against dementia and other aging, medical and non-medical challenges facing mankind.

But that™s tomorrow, and this is today. And I just got some exciting news. A new study shows that the dementia problems facing us TODAY are not as gloomy as advertised. And it should get better, not worse. In other words, your chances of getting Alzheimer™s as you age are not as severe as we thought, even without new advances.

As published in a new Bloomberg article, œWhen it comes to brain power, 90 may be the new 80.

The article notes that those surviving past the age of 90 today are living longer and are mentally sharper than people in their 90s born a decade earlier. This was reported by Danish researchers.

Here are some excerpts from the article:

œPeople born in 1915 were almost a third more likely to reach 95 than those born a decade earlier and on average they performed better on mental tests and in daily living tasks, according to a study published {today} in The Lancet

œThe findings are the latest in a small but growing body of evidence that suggest improved nutrition, vaccinations, health care and intellectual stimulation are leading to a better quality of life for the elderly. Among the most intriguing findings of the Danish study is the notion that, should the trend continue, the care needs of very elderly people may be less than now anticipated.

œThere™s a fear that getting older means many years of living in bad shape with a rather gloomy outlook,Â Kaare Christensen, the lead study researcher from the University of Southern Denmark in Odense, Denmark, said in an interview. œI™m looking forward to living longer than 90 myself after this study.

Mental Agility


œIn the Danish study, stronger, sharper mental agility among today™s 90 year-olds was marked compared with the earlier group. That™s significant because improved cognition at very old age goes against expectations there will be a sharp rise in dementia among people over 80, Marcel Olde Rikkert and Rene Melis of Radboud University Nijmegen Medical Centre in Nijmegen, Netherlands, wrote in a commentary about the study.

œUsing the Danish Civil Register System to identify subjects, researchers surveyed 2,262 people born in Denmark in 1905 who were still living in 1998 and 1,584 Danes born in 1915 who were still alive in 2010, at ages of about 93 and 95, respectively.

œResearchers used physical and mental tests as well as interviews to measure mental impairment, depression and ability to perform daily tasks. While the two groups were about the same in terms of physical strength, those in the 1915 group had a better œdaily living score, which was based on being able to walk around the house, get upstairs or live alone.

œEven after adjusting for education levels, the 1915 group performed better on cognitive tests and had twice the rate of perfect scores.

œThe Danish study is the most conclusive evidence yet that the elderly may be in better health than ever.

Moreover, The chance of surviving from birth to age 93 years was 28% higher in the 1915 group than in the 1905 group, and the chance of reaching 95 years was 32% higher in 1915 group.

Less Frailty in GHRKO and Calorie Restricted Mice - Monday, July 8, 2013
Growth hormone receptor knockout (GHRKO) mice are smaller, age more slowly, and live considerably longer than their unaltered peers. Researchers have yet to create a longer-lived mouse lineage.

Interestingly, and perhaps unfortunately for the prospects of slowing aging in our species, similar human mutants do not appear to live longer than the rest of us. Much the same is true of the practice of calorie restriction: long-lived mice, tremendous health benefits in both mice and humans, but no signs of greatly extended life in humans.
Aging more slowly, either through disruption of growth hormone metabolism or through calorie restriction, means that all measures of degeneration are impacted - such as the frailty and muscular weakness examined by these researchers.

Working on Artificial Replacements for Nerve Grafts - Tuesday, July 9, 2013
Researchers are making progress on the construction of cell structures that look very much like naturally formed nerve tissue, and may thus be useful substitutes for the current practice of nerve grafting.

Correlating Rate of Aging With Metabolism in Infancy - Tuesday, July 9, 2013
Reliability theory can be used to model aging in terms of progressive failure of component subsystem, just as occurs in electronic equipment and other systems prone to complex forms of decay.

One of the predictions that results from this method is that we are born with a preexisting level of damage, and so we should expect to see correlations between aspects of newborn biology and later aging. On a similar note it has been determined in recent years that at least some species adjust the metabolism of their descendants in reaction to environmental factors such as availability of food.

Calorie restriction, for example, doesn't just change the metabolism of the individuals that are living on fewer calories, but also results in different patterns of gene expression that show up in their offspring. Here is an example of a correlation between early life metabolism and later life progression of aging in humans, which might be considered in the context provided by the above points.

IGF-1 Induced Longevity Accompanied by Reduced Protein Translation and Increased Autophagy - Wednesday, July 10, 2013
Enhanced longevity associated with changes in the insulin/IGF-1 pathway is one of the most studied areas of the genetics of longevity in laboratory animals. Metabolism is complex enough that researchers are still building the picture of how alterations like this work to extend life.

The open access research quoted below suggests that broad reductions in rate of creation of proteins from DNA blueprints are involved, and thus a related boost in the level of autophagy as the body seeks to recycle more proteins.

This shows up elsewhere in processes related to longevity - for example in dietary methionine restriction, as methionine is required for the assembly of all proteins. Increased levels of the housekeeping processes of autophagy appear in many forms of metabolic alteration that extend life, and most likely work by consistently reducing the levels of cellular damage that contribute to degenerative aging over the long term.

Examining the Mechanisms Behind Loss of Insulin Sensitivity in Sedentary Individuals - Wednesday, July 10, 2013
Being sedentary has a cost: your health will most likely be worse, and your life expectancy shorter.

One of the metabolic dysfunctions that arises with increasing age is a reduction in insulin sensitivity, most often associated with excess fat tissue and the descent into type 2 diabetes, but lack of exercise is also an important contributing factor. Here researchers look into some of the low-level biological mechanisms involved in the relationship between exercise and insulin metabolism.

Thoughts on Maintaining the Self While Upgrading the Brain to Machinery - Thursday, July 11, 2013
It would be a good thing to have a brain that is a robust collection of artificial machinery when such a thing becomes possible, as the present evolved biological human brain is short-lived and frail in comparison to what could be achieved with a mature nanorobotics industry, capable of producing robust nanomachines that replicate cell functions.

But how do you move from a biological to a machine brain without destroying or merely copying yourself?

The first order of business is to develop the means to repair aging in our biology, to give us enough time to live into a future in which things like brain upgrades are possible.
Later in the piece quoted below the half-brain methodology is discussed. The safest approach is to scale down the replacement to the level of individual cells, proceeding at a pace similar to the natural processes of cell replacement in the brain.

Surf1 Knockout Mice Live Longer, Have Better Memories - Thursday, July 11, 2013
The effort to understand how exactly metabolic processes determine longevity is a frustrating business. Researchers are at the stage in the game where they can increase or reduce longevity in many different ways through various genetic and epigenetic manipulations in mice, worms, flies, and other laboratory species.

They can obtain mountains of data from these longer-lived or shorter-lived animals: gene expression patterns and any number of different measures of metabolism and the operation of organs and cells. Making sense out of all this data is the challenge. For example, some interventions boost the free radical output of mitochondria and extend life. Others raise that free radical output and reduce life span.

Here is an example of a life-extending and memory-improving genetic alteration in mice that reduces mitochondrial function (generally thought to be a bad thing) and increases the output of damaging free radicals from the mitochondria (also generally thought to be a bad thing).

Creating Inner Ear Structures from Stem Cells - Friday, July 12, 2013
Scientists demonstrate the ability to make stem cells assemble into small inner ear structures in this research. This is a long way from building tissue masses that are easy to see with the naked eye, but it is progress nonetheless.

Improved Outcomes for Long-Lived Individuals Born in 1915 Versus Those Born in 1905 - Friday, July 12, 2013
If asked yesterday, I'd have guessed that there wasn't a great deal of difference in the majority of the life history of people born ten years apart in the early 1900s in Europe: a small incremental improvement in adult life expectancy for those born later and a larger improvement in life expectancy at birth due to lowered infant mortality. Advances in medicine are weighted towards the recent past: progress is speeding up and practical improvements in medical technology - and patient outcomes - are presently arriving far more rapidly than, say, fifty or a hundred years ago. So the study noted below may be largely measuring improvements in medical care for the elderly that have taken place across the past few decades rather than anything that happened prior to that.
