    The National Institute on Aging has been working to stimulate health disparities research related to aging. An opportunity is currently available for researchers interested in aging, stress, resilience, and health disparities. There are also exciting, new funding opportunities for Alzheimer’s Disease research that focuses on health disparities.

    In July of 2015, the Office of Special Populations successfully posted a Funding Opportunity Announcement for administrative supplements entitled Aging Research to Address Health Disparities. The announcement was intended to expand existing research in specific areas of interest to include development of new measures to facilitate research on the behavioral and social mechanisms leading to disparities in health; addition of sub-group analyses to existing studies; studies focused on racial, ethnic or gender disparities in stress-responses; and studies focused on racial or ethnic disparities in functional, physiologic, or metabolic outcomes across the life span and in old age.

    The administrative supplement supports the NIA’s health disparity goals of (1) understanding environmental and sociocultural factors and related behavioral and biological mechanisms that diminish health and reduce life expectancy for populations that experience health disparities, (2) developing strategies to increase life expectancy among aging adults and improve the health status of elders from underserved and disadvantaged populations, and (3) using research insights and advances to inform policy that reduces health disparities. The parent projects that were supported cover a broad range of research areas (see below).

    We look forward to learning of valuable findings that inform health disparities research related to aging!

    Dr. Angus Deaton

    The 2015 Nobel Prize in Economic Sciences has been awarded to National Institute on Aging grantee Angus Deaton, Ph.D., of Princeton University, N.J.

    “The National Institute on Aging is proud to have supported Dr. Deaton’s work for more than 20 years,” said NIA Director Richard J. Hodes, M.D. “His work has examined how circumstances including income inequality and early childhood nutrition influence health and subjective well-being across the life course in the United States and around the world.”

    Deaton’s NIA funded research has focused on measuring poverty among the elderly in the US, the influence of income and inequality on health and mortality in high, middle, and low income countries, as well as the role of work in the decline of health at older ages. His more recent funded work focused on the measurement of subjective well-being, a self-reported quality of life measure. Dr. Deaton has examined the impact of the financial crisis on well-being in the United States as well as how subjective measures of wellbeing vary across people in different societal groups and in different countries. His funded research has been published in high-profile medical and economics journals such as PNAS, Lancet and the American Economic Review.

    Deaton has also received support from the Fogarty International Center at NIH.

    NIA congratulates Dr. Deaton on his outstanding contributions to health science.

    The ability to suppress inappropriate behavioral responses—known as cognitive inhibitory control—is essential for everyday living. The time required for the brain to inhibit a response is called the stop-signal reaction time. Certain conditions such as Parkinson’s disease, attention deficit hyperactivity disorder, schizophrenia, and even normal aging, can affect cognitive inhibitory control, resulting in a slower stop-signal reaction time.

    Basic studies are underway to help better understand the mechanisms behind this process, which may ultimately lead to new therapeutic targets for people with cognitive problems affecting stop signal reaction times. One new finding, reported online Sept. 14, 2015 in Nature Neuroscience, provides important new insights. Most research to date on cognitive inhibitory control and stop-signal reaction time has focused on the fronto-basal-ganglia circuit, a part of the brain that helps control movement. Now, researchers from the Laboratory of Behavioral Neuroscience at the National Institute on Aging at NIH and Johns Hopkins University provide new evidence that this cognitive function might also be controlled by the inhibition of neurons in another part of the brain, the basal forebrain, the bottom-front part of the brain typically associated with the wake and sleep states as well as with learning and memory. Changes in the basal forebrain have also been associated with age-related cognitive decline, as well as Alzheimer’s disease.

    In the study, investigators trained rats to respond to a sound, but to inhibit their response if the sound was immediately followed by a light signal. Researchers measured the rats’ stop-signal reaction times and recorded neuronal activity in the basal forebrain.

    Researchers found that the neurons in the basal forebrain of rats were silenced—not firing signals—immediately before cognitive inhibitory control. The faster the neurons were silenced, the shorter the stop-signal reaction time. This link was further established when scientists artificially silenced basal forebrain neurons and saw that the rats would no longer respond to sound even when there was no light signal. This suggests that basal forebrain neurons alone are powerful enough to exert cognitive inhibitory control over behavior in the rats.

    Being obese or overweight in middle age has been linked to increased risk of dementia. To learn more, researchers at the National Institute on Aging, part of the NIH, further explored the relationship between weight at midlife and Alzheimer’s among volunteers participating in the Baltimore Longitudinal Study of Aging (BLSA), one of the longest running studies of human aging in North America. They found that being obese or overweight at midlife—as measured by body mass index (BMI) at age 50—may predict earlier age of onset of the devastating neurodegenerative disorder. The study, led by Madhav Thambisetty, M.D., Ph.D., will appear online Sept. 1, 2015, in Molecular Psychiatry.

    Cognitively healthy at the start of the nearly 14-year study, each of the 1,394 BLSA participants received cognitive testing every one to two years; 142 volunteers eventually developed Alzheimer’s disease. The investigators found:

    • Each unit increase in BMI at age 50 accelerated onset by nearly 7 months in those who developed Alzheimer’s disease.
    • Higher midlife BMI was associated with greater levels of neurofibrillary tangles—a hallmark of the disease—in the brains of 191 volunteers, including those who did not develop Alzheimer’s.
    • Among 75 cognitively healthy volunteers who had brain imaging to detect amyloid, a protein whose fragments make up the brain plaques that are a hallmark of Alzheimer’s, those with higher midlife BMI had more amyloid deposits in the precuneus, a brain region that often shows the earliest signs of Alzheimer’s-related changes.

    More study is needed to determine the relationship behind BMI at midlife and Alzheimer’s onset. The findings suggest, however, that maintaining a healthy BMI at midlife might be considered as one way to delay the onset of Alzheimer’s.

    The brains of people who live to age 90 and older—the oldest-old—usually have a mix of pathologies associated with dementia. Alzheimer’s disease-related brain changes are the most common, but other pathologies often found at autopsy include infarcts, Lewy bodies, hippocampal sclerosis, and white-matter disease. For the first time, researchers examined the relationship between the number of pathologies found at autopsy and the severity of dementia in the oldest-old. They found the more pathologies present in the brain, the more severe the dementia, and that Alzheimer’s pathology alone was less damaging to cognition than mixed pathologies.

    The study led by Claudia Kawas, M.D., and Maria M. Corrada, Sc.D., University of California, Irvine, involved 183 volunteers in The 90+ Study, one of the largest studies tracking the well-being of the oldest-old in the world. The participants, 70 percent of whom were women, received physical and cognitive testing every 6 months. When they died at an average age of 97, about 54 percent were diagnosed with dementia. Their donated brains were examined for eight different cerebral pathologies.

    The investigators found:

    • Alzheimer’s pathology alone was less likely to result in dementia. Alzheimer’s was found in about the same number of people with dementia (28 percent) and those without symptoms (23 percent).
    • Mixed pathologies, however, increased risk for dementia; they were found in 45 percent of those with dementia and in 14 percent of symptom-free volunteers.
    • Non-Alzheimer’s disease pathologies appeared more likely to result in dementia. People with a single non-Alzheimer’s pathology were 12 times more likely to have dementia than those with no pathology. In contrast, those with Alzheimer’s pathology were 3 times more likely to have dementia than those with no pathology.
    • Dementia prevalence increased with the number of pathologies found in the brain, from 22 percent in people with no pathologies to 95 percent of those with 3 or more pathologies.
    • Dementia severity also increased in direct proportion to the number of pathologies found in the brain. For example, people with mixed pathologies, such as Alzheimer’s hippocampal sclerosis and white-matter disease, had more severe symptoms than those who only had Alzheimer’s pathology.

    Fasting, the most extreme form of dietary restriction, has been shown to have multiple health benefits in many – but not all – animal models, but may not be a practical or safe long-term intervention for people.  A team of researchers, led by scientists at the University of Southern California, studied the effects of a short-term fasting-like diet in mice and humans to determine potential health benefits.   

    Mice fed a low-calorie, low-protein fasting-mimicking diet (FMD) for 4 days twice a month and allowed to eat freely between FMD cycles experienced a number of health benefits. These included reduced cancer incidence, total fat, and inflammation. In addition, mice in the FMD group performed better on tests of short- and long-term memory, indicating that FMD may improve memory and cognition. On average, mice on FMD also lived 3 months (or approximately 11 percent) longer than mice in the control group.

    To understand whether FMD may have the same advantages in humans as in mice, the researchers conducted a small, 3-month pilot study with 19 healthy volunteers in the intervention arm. Study participants followed a short-term FMD regimen, eating 1,100 kcal on day one, 725 kcal on days two through five, and their regular diet for the remainder of the month. After 3 months, researchers found participants on FMD had a 3 percent reduction in body weight and reduced risk factors for diabetes, heart disease, and cancer.

    The researchers strongly cautioned that the FMD used in the pilot study was an experimental approach, requiring close and continuous medical supervision. More research is needed to determine the effects of FMD, particularly in the long-term.
