Long Term care Insurance Expert Reports Low Vitamin B12 Linked To Cognitive Decline In Elderly

Older individuals who have low levels of vitamin B12 in their blood have a greater risk of brain shrinkage, losing cognitive skills and greater risk of needing long term health care.

"The number of U.S. adults aged 65 years and older is projected to nearly double over the next two decades," explains Jesse Slome, executive director of the American Association for Long Term Care Insurance, the national trade organization.  "As a result, the incidence of cognitive issues especially Alzheimer's disease and other dementias is also expected to rise as will the need for costly long term care."

According to Chicago researchers foods rich in vitamin B12 include those derived from animals and include, eggs, milk, liver, meat, and fish.  Vitamin B12 plays a key role in normal nervous system functioning and brain development. It is also involved in the formation of red blood cells.

Scientists undertook a study of individuals aged at least 65 years. They underwent blood tests to check for B12 and B12-related metabolites levels. They were also assessed for memory and other cognitive skills. Some five years later magnetic resonance imaging scans of their brains were taken to measure comparative brain size and to identify other signs of brain damage.

Those with four of five markers for vitamin B12 deficiency were found to have a higher risk of getting lower cognitive test scores and smaller total brain volumes.  The National Institute of Aging funded the study.

Vision Of Elderly Can Improve

Elderly adults can improve their vision with perceptual training.

According to a study from the University of California, Riverside and Boston University elderly adults can improve their vision with perceptual training.  This has positive implications for the health and mobility of senior citizens.

UCR researchers and Boston University psychology professors conducted a series of experiments to determine whether repeated performance of certain visual tasks that are at the limits that one can see can improve the vision of adults older than 65.

The researchers found that with just two days of training, in one-hour sessions, with difficult stimuli resulted in older subjects seeing as well as younger college-age subjects.  The improvement was maintained for up to three months and the results were dependent on the location in the visual field where the stimuli were located - suggesting that the brain changed in early levels of visual cortex.

Age-related changes in vision - such as contrast sensitivity, dark adaptation, visual acuity, spatial vision, orientation, depth perception and motion perception - have been substantiated in numerous previous studies. This is the first study that demonstrates that perceptual training can be used to improve vision among the elderly in the earliest levels of visual processing.

The researchers used a texture discrimination test in which the participants were presented with stimuli consisting of a letter embedded in the center of a field of horizontally oriented lines. In addition to the letter, an array of peripherally located lines was oriented diagonally and formed either a vertical or horizontal object, always presented in the same quadrant. That was followed quickly with the display of a masking pattern. The task was to identify the central letter and the peripheral object.

 After age 60 there is a steady increase in the incidence of falls and automobile crashes that are associated with changes in visual processing reports the American Association for Long-Term Care Insurance which tracks health related issues impacting aging Americans.

Hospitalized Patients With Sepsis Seniors More Likely To Get Alzheimer's

Older patients hospitalized for severe sepsis are at higher risk for long-term cognitive impairment and physical limitations than those hospitalized for other reasons.

The conclusion was reported following a study by ached by the Department of Preventive Medicine at Stony Brook University Medical Center and reported in the Journal of the American Medical Association.

Sepsis is a condition in which the immune system goes into overdrive releasing chemicals into the blood to combat infection. Sepsis occurs in 1 percent to 2 percent of all hospitalizations in the United States. Sepsis often results after common problems such as pneumonia and urinary tract infections.

Approximately 40 percent of those with severe sepsis die from the condition.  Among surviving patients the researchers found that the odds of acquiring moderate to severe cognitive impairment were 3.3 times higher following an episode of sepsis than for other hospitalizations.

Overall, the study also showed that 60 percent of hospitalizations for severe sepsis were associated with worsened cognitive and physical function among surviving older adults. Severe sepsis also was associated with greater risk for the development of new functional limitations following hospitalization.

Among patients who had no limitations before sepsis, more than 40 percent developed trouble with walking. Nearly 1 in 5 developed new problems with shopping or preparing a meal. Patients often developed new problems with such basic things as bathing and toileting themselves both conditions that result in the need for long-term health care services according to the American Association for Best Long-Term Care Insurance Information (AALTCI) a national trade group.   

Patients in the study had a mean age of nearly 76.9 years. The cohort involved 1,194 individuals with 1,520 hospitalizations for severe sepsis drawn from the Health and Retirement Study, a nationally representative survey of U.S. residents from 1998 to 2006, which collects information on the health, economic, and social factors influencing the health and well-being of Americans over age 50. 

Carrots And Celery Reduce Memory Decline

Diets rich in the plant compound luteolin reduces age-related inflammation in the brain and related memory deficits.   

Luteolin is found in many plants, including carrots, peppers, celery, olive oil, peppermint, rosemary and chamomile.  The compound inhibits the release of inflammatory molecules in the brain.

According to researchers who examined the effects of dietary luteolin in a mouse model of aging and reported their findings in the Journal of Nutrition.

The researchers focused on specialized immune cells that reside in the brain and spinal cord.   Inflammation in the brain also appears to be a key contributor to age-related memory problems, said the University of Illinois animal sciences professor who led the new study.

Scientists found previously that during normal aging, microglial cells become dysregulated and begin producing excessive levels of inflammatory cytokines.  The researcher has spent nearly a decade studying the anti-inflammatory properties of nutrients and various bioactive plant compounds, including luteolin.

According to the American Association for Long-Term Care Insurance which tracks aging research and issues, this is the first study to suggest, however, that luteolin improves cognitive health by acting directly on the microglial cells to reduce their production of inflammatory cytokines in the brain.

The researchers showed that microglial cells that were exposed to a bacterial toxin produced inflammatory cytokines that could kill neurons. When the microglia were exposed to luteolin before they encountered the toxin, however, the neurons lived.

The researchers next turned their attention to the effects of luteolin on the brains and behavior of adult (3- to 6-month-old) and aged (2-year-old) mice. The mice were fed a control diet or a luteolin-supplemented diet for four weeks. The researchers assessed their spatial memory and measured levels of inflammatory markers in the hippocampus, a brain region that is important to memory and spatial awareness.

Normally, aged mice have higher levels of inflammatory molecules in the hippocampus and are more impaired on memory tests than younger adult mice. Aged mice on the luteolin-supplemented diet, however, did better on the learning and memory task than their peers, and the levels of inflammatory cytokines in their brains were more like those of the younger adult mice.

The data suggests that consuming a healthy diet has the potential to reduce age-associated inflammation in the brain, which can result in better cognitive health.

23 Million Seniors Can Expect Less From Social Security

The combination of rising Medicare premiums and no annual cost-of-living adjustment would reduce Social Security payments for about 23 million of the nation's seniors.

The decrease in 2011 according to The Senior Citizens League represents two-thirds of the 37 million seniors who receive Social Security benefits.

The estimate is based on the group's recent survey of more than 2,400 seniors. Half of them said they received lower Social Security benefits after Medicare premium deductions this year, due to the lack of a COLA for the first time in 35 years.

The same situation is expected next year, because the Social Security Trustees and Congressional Budget Office have predicted that inflation will again remain too low to pay a COLA. Medicare premiums, on the other hand, are expected to increase.

Another year of no COLA will put Social Security benefits through the wringer said an expert. After paying their Medicare health insurance premiums, seniors will have even less to spend on other essentials. This will force many of them to fall below the poverty line.

Forty-seven percent of those surveyed said their annual Social Security benefits were reduced by at least $132 in 2010; about ten percent reported that their benefits dropped by more than $840.

The Senior Citizens League strongly supports legislation that would provide an emergency COLA or guarantee a minimum average COLA to prevent the erosion in Social Security benefits.

This is simply more proof that aging Americans must plan for their own future including retirement savings plans and long term insurance protection states Jesse Slome, executive director of the American Association for Long-Term Care Insurance.  For more information and a free on reducing the cost of insurance, visit the organization's website.

Study Examines Falls Among Seniors

The risk factors for indoor and outdoor falls for older adults are different, according to a new study.

Researchers at the Aging Research of Hebrew SeniorLife, an affiliate of Harvard Medical School, reported a fact that is often missed when the two are combined.  Their findings may affect how falls prevention programs are structured.

The scientists noted that indoor and outdoor falls are both important.  But they note that  people at high risk for indoor falls are different in many ways from those at high risk of outdoor falls.

The findings which were published online in the Journal of the American Geriatrics Society, found that indoor falls are associated with an inactive lifestyle, disability, and poor health, while outdoor falls are associated with higher levels of activity and average or better-than-average health.

Older adults who fell outdoors were somewhat younger than those who fell indoors, more likely to be male and better educated, and had lifestyle characteristics indicative of better health. Those who fell indoors had more physical disabilities, took more medications, and had lower cognitive function than those who fell outdoors.

The study examined nearly 800 men and women, age 70 and older, from randomly sampled households in the Boston area. Study participants underwent a comprehensive baseline falls assessment, including a home visit and clinic examination. Falls were reported on monthly calendars submitted to the researchers. Over a nearly two-year period, 598 indoor falls and 524 outdoor falls were reported. When a participant reported a fall, a structured telephone interview was conducted to determine the circumstances.

A fall the scientists report is not necessarily a marker of poor health. In fact, almost half of all falls occurred outdoors, and people who fell outdoors had the same or better health than those who did not fall at all. Second, epidemiological studies of risk factors for falls in older people may be hampered when falls are combined, with important associations between risk factors and indoor and outdoor falls potentially being missed. Third, intervention programs need to be tailored differently for people more likely to fall outdoors than those who tend to fall indoors.

According to the American Association for Long-Term Care Insurance, seniors who fall suffer moderate to severe injuries, including hip fractures and traumatic brain injuries. At least half of these falls occur outdoors.  Falls are a leading cause for needing long-term care.

Vitamin B May Help Dementia Alzheimer's Disease

A new study reveals that elderly individuals with mild cognitive impairment who take huge doses of B vitamins everyday may reduce the rate at which their brains shrink by 50%, resulting in a much slower progression toward dementia, and eventually Alzheimer's disease.

According to the findings of studies conducted by researchers from Oxford University, England, in an article published in Plos One (Public Library of Science One), this two-year clinical trial is the largest ever which examined the effect of B vitamins on "mild cognitive impairment" (MCI).

Individuals with MCI have a higher risk of progression to Alzheimer's disease and other forms of dementia notes Jesse Slome, director of the American Association for Long-Term Care Insurance the industry's trade group.

"People with mild cognitive impairment can function in everyday activities, but they may have problems with memory, such as recalling people's names, losing the flow of a conversation, and not remembering where they left things," Slome explains. Approximately 16% of individuals aged over 70 years are affected by mild cognitive impairment.

David Smith, University Department of Pharmacology and Department of Physiology, Anatomy & Genetics, University of Oxford, trial co-leader, said:

The single-center, randomized, double-blind controlled trial involved 168 volunteers who all had been diagnosed with mild cognitive impairment. One group received high daily doses of vitamins B6 (0.5 mg/d) and B12 (20 mg/d), as well as folic acid (0.8 mg/d). This was 300 times the recommended daily intake for B12, 15 times daily recommended amounts of B6, and 4 times daily recommended intake of folic acid.

The other group received a placebo (tablets without any active ingredients). Treatment lasted 24 months.

The principal outcome measure was the change in the rate of atrophy of the whole brain, assessed by serial volumetric MRI scans.

The researchers found that the B vitamin with folic acid group had an average brain shrinkage of 0.76% per year. The placebo group had an average brain shrinkage of 1.08% per year.

Those with the highest homocysteine blood levels at the start of the trial who took the B vitamins and folic acid experienced half the brain shrinkage compared to individuals with the highest homocysteine blood levels at the start and who received the placebo.
