Health Tip: Make Your Home Safer For People With Alzheimer's

Posted 19 hours ago by

-- It's important to keep your home as safe as possible, especially if a loved one has Alzheimer's disease. The U.S. National Institute on Aging offers these suggestions: Clearly post emergency numbers and your home address near any telephone. Install secure locks on all outside doors and windows. Install alarms that notify you when a door or window is opened. Hide a spare house key outside, in case the person with Alzheimer's locks you out of the home. Avoid extension cords, which could pose tripping hazards. Cover unused electrical outlets with childproof inserts. Place red tape around floor vents, radiators and other heating devices to deter the person with Alzheimer's from approaching them. Check all rooms for adequate lighting. Stairways should have at a handrail that extends beyond the first and last steps. If possible, stairways should be carpeted or have safety grip strips. Put ... Read more

As Hearing Fades With Age, Dementia Risk May Rise

Posted 9 days ago by

THURSDAY, Dec. 7, 2017 – Age can often bring a loss of hearing, and for some, mental decline in the form of dementia. But are the two linked? New research does suggest that hearing loss raises the odds for dementia, but the jury is still out on whether one condition actually causes the other, experts say. According to a team of Irish researchers at Trinity College Dublin, approximately one-third of adults older than 65 years experiences age-related hearing loss. And prior research suggests that a loss of hearing often – but not always – precedes the onset of dementia by about 5 to 10 years. In the new study, a team led by Trinity's David Loughrey reviewed data from 36 studies that included more than 20,000 people across the world. The investigators found a small association between age-related hearing loss and increased risk for mental decline, mental impairment and dementia. "The ... Read more

Alzheimer's Cases to Double by 2060: Report

Posted 9 days ago by

THURSDAY, Dec. 7, 2017 – As the baby boomer population ages, the number of Americans with Alzheimer's disease will double by 2060, researchers report. The study findings, which show cases of Alzheimer's and mild cognitive impairment going from 6 million this year to 15 million in four decades, highlight the need to better identify people with a brain-related disease, and to slow its progression. "There are about 47 million people in the U.S. today who have some evidence of preclinical Alzheimer's," said study author Ron Brookmeyer. He is a professor of biostatistics at the Fielding School of Public Health at University of California, Los Angeles. "Many of them will not progress to Alzheimer's dementia in their lifetimes. We need to have improved methods to identify which persons will progress to clinical symptoms, and develop interventions for them that could slow the progression of ... Read more

Gene Discovery May Help Fight Alzheimer's

Posted 11 days ago by

TUESDAY, Dec. 5, 2017 – Alzheimer's disease has long remained a deadly mystery. But scientists say they've now pinpointed a rare piece of DNA that may shield against the illness – even in people who are otherwise at high risk. The discovery may explain why some people with known genetic risk factors don't develop Alzheimer's, the study authors said. And it could lead to new ways to fight the memory-robbing disease. For example, this genetic function could potentially be targeted with drugs to help lower people's odds of developing Alzheimer's. "There are currently no meaningful interventions for Alzheimer's disease – no prevention, no modifying therapies, no cure," said study co-leader John Kauwe. He is a professor at Brigham Young University in Provo, Utah. "The discoveries we're reporting in this manuscript provide a new target with a new mechanism that we believe has great ... Read more

Chuck Norris Says MRI Dye Harmed Wife's Brain, But Study Finds No Link

Posted 17 days ago by

WEDNESDAY, Nov. 29, 2017 – Despite recent claims from actor Chuck Norris that a dye commonly used during MRI scans seriously sickened his wife, a new study finds no evidence to support such a link. The substance in question is gadolinium. It's a metal found in contrast agents that are injected into the body during an MRI scan, to enhance the quality of the images. Earlier this month, Norris filed a lawsuit alleging that his wife fell ill after being exposed to gadolinium during MRI scans. The suit says that Gena Norris was left weak, tired and suffering bouts of pain and burning sensations. Doctors have been using gadolinium-based agents for 30 years – totaling more than 300 million doses, said Dr. Vikas Gulani, an associate professor of radiology at Case Western Reserve University in Cleveland. But, Gulani explained, researchers have only recently discovered that trace amounts of the ... Read more

Does Marriage Help Preserve Your Brain?

Posted 17 days ago by

WEDNESDAY, Nov. 29, 2017 – Tie the knot, save the brain? A new research review suggests there's something about marriage – or people who get and stay married – that significantly lowers the risk of mental decline in old age. "We were surprised by the strength of our findings," said review lead author Dr. Andrew Sommerlad, a psychiatrist in England. The new analysis found that lifelong single people have a 42 percent higher likelihood of developing dementia than married people. Widowed people also have a higher rate of dementia, but divorced people don't. The findings don't prove a direct link between marriage and lower risk of dementia, however. Still, "the higher risk for unmarried people remains even when physical health is taken into account, suggesting that the benefit of marriage is due to more than just improving physical health," said Sommerlad, a research fellow at University ...

Intense Workouts May Boost Memory

Posted 18 days ago by

TUESDAY, Nov. 28, 2017 – Pump up your workouts, pump up your memory, new research suggests. The study of 95 healthy young adults showed that six weeks of 20-minute bouts of interval training led to significant improvements in what's called high-interference memory. An example of this type of memory is distinguishing your car from another of the same make and model. The Canadian scientists also found these workouts led to increases in a protein involved in the growth, function and survival of brain cells. The results were published in the November issue of the Journal of Cognitive Neuroscience. The findings could prove important as an aging population leads to higher rates of Alzheimer's disease and other types of dementia, according to the researchers from McMaster University in Hamilton, Ontario. "Improvements in this type of memory from exercise might help to explain the previously ... Read more

More Docs Specializing in Nursing Home Care

Posted 18 days ago by

TUESDAY, Nov. 28, 2017 – More doctors in the United States are turning to a new clinical specialty – nursing home care. The number of physicians and health care providers concentrating on nursing home patients grew by about one-third between 2012 and 2015, researchers from the University of Pennsylvania School of Medicine found. The trend is likely driven by the aging population and increased federal government oversight of nursing homes, the researchers said. "We don't know how this trend will play out in the long term, but nursing home specialists have the potential to change the way health care is delivered in this setting," said lead author Dr. Kira Ryskina, an assistant professor at UPenn. "On one hand, clinicians who practice in the nursing home exclusively could improve patient outcomes and reduce costs by leveraging expertise in nursing home processes of care, for example," ...

Could New 'Brain Training' Program Help Prevent Dementia?

Posted 18 Nov 2017 by

FRIDAY, Nov. 17, 2017 – In what is being billed as a first, researchers report that healthy seniors who tried a new brain-training program were less likely to develop dementia down the road. "Everyone with a brain is at risk of dementia," noted study author Jerri Edwards. But "this is the first treatment ever shown in a clinical trial to make a difference." Edwards is a professor in the department of psychiatry and behavioral neurosciences at the University of South Florida. In essence, the program tries to speed thinking by giving seniors the task of distinguishing between a series of ever-changing objects on a computer screen – both in the center and periphery of their vision. Over time, the objects appear more quickly, and look more similar to one another. This makes the task increasingly difficult, with the aim being to boost the individual's ability to rapidly and accurately ... Read more

Health Tip: Hearing Loss May Affect Brain Health

Posted 15 Nov 2017 by

-- About a third of people aged 65 to 74 are affected by hearing loss, as are about half of those 75 and older, the U.S. National Institute on Aging says. Aside from missing out on spirited conversation, hearing loss can affect the health of your brain, the agency says. A 2011 study funded by the NIA found that older adults with hearing loss were more likely to develop dementia than older adults with normal hearing. The degree of hearing loss was directly related to the increase in dementia risk. Mild hearing loss was associated with a two-fold increase, moderate loss with a three-fold increase, and severe hearing loss with a five-fold increase in dementia risk. And it appears memory isn't the only brain function affected. A more recent study found that concentration declined faster in older adults with hearing loss, as compared to older adults with normal hearing. Read more

Millions Could Miss Out on a Potential Alzheimer's Breakthrough

Posted 15 Nov 2017 by

WEDNESDAY, Nov. 15, 2017 – Even if researchers were to find a groundbreaking new treatment for Alzheimer's disease, millions of people might not benefit from it, new research reveals. That's because the U.S. health care system doesn't have the ability to quickly implement a newly approved treatment on a widespread scale, according to a report from the RAND Corporation. For instance, there aren't enough doctors to diagnose all the people with early signs of dementia who would be good candidates for such a treatment, the researchers explained. In addition, scanners used to detect the disease are in short supply, and there aren't enough treatment centers that could administer the therapy to patients. An estimated 5.5 million Americans are currently living with Alzheimer's disease. By 2040, that number is expected to jump to 11.6 million, according to the study authors. "While significant ...

Sleep Apnea May Boost Alzheimer's Risk

Posted 10 Nov 2017 by

FRIDAY, Nov. 10, 2017 – If your sleep is continually disrupted by a condition called sleep apnea, you might face a higher chance of developing Alzheimer's down the road. So claims a new study that has linked sleep apnea with an increase in the development of amyloid plaque in the brain, a hallmark of Alzheimer's disease. The researchers found that the more serious the sleep apnea was, the more plaque accumulated. "Sleep apnea is very common among the elderly, and many aren't aware they have it," said senior researcher Dr. Ricardo Osorio. He is an assistant professor of psychiatry at New York University School of Medicine in New York City. An estimated 30 percent to 80 percent of the elderly suffer from sleep apnea, depending on how it's defined, the study authors noted. Although none of the participants developed Alzheimer's over the two years of the study, those with sleep apnea ... Read more

An Aging Heart May Weaken Memory

Posted 8 Nov 2017 by

WEDNESDAY, Nov. 8, 2017 – A decline in the pumping ability of an older person's heart can lower blood flow to their brain's memory center, new research has found. The study involved 314 people, who averaged 73 years old and did not have heart failure, stroke or dementia. Nearly 40 percent of them had mild cognitive impairment, which increases the risk for dementia, including Alzheimer's disease. All participants underwent tests to determine how much blood their heart pumped relative to their body size. They also had MRI scans to assess blood flow in the brain. "Our findings show that when the heart does not pump blood as effectively, it may lead to reduced blood flow in the right and left temporal lobes, areas of the brain that process memories," said study author Angela Jefferson. She directs Vanderbilt University Medical Center's Memory & Alzheimer's Center, in Nashville. "What is ... Read more

New Finding Hints at Clue to Dementia

Posted 3 Nov 2017 by

FRIDAY, Nov. 3, 2017 – Inflammation in middle age may increase the risk for brain shrinkage and dementia in old age, a new study suggests. The researchers tested more than 1,600 people for five "biomarkers" of inflammation in their blood when they were, on average, 53 years old. About 24 years later, the participants were given brain scans and a memory test. Compared with people who had no elevated levels of the biomarkers, those with elevated levels for three or more biomarkers had an average of 5 percent lower volume in the hippocampus and other areas of the brain associated with Alzheimer's disease. They also had lower scores on the memory test. The study was published online Nov. 1 in the journal Neurology. "These results suggest that inflammation in midlife may be an early contributor to the brain changes that are associated with Alzheimer's disease and other forms of dementia," ... Read more

Resilient Brain Connections May Help Against Alzheimer's

Posted 2 Nov 2017 by

THURSDAY, Nov. 2, 2017 – Certain pieces of brain structure may make some people less likely to develop Alzheimer's disease. That's the conclusion of a new study that could lead to new ways to prevent or slow the memory-destroying disease, researchers said. For the study, the researchers analyzed brain samples from patients at memory clinics and found that the presence of healthy dendritic spines (connections between neurons) provide protection against Alzheimer's in people whose brains have proteins associated with the disease. The findings, published recently in the Annals of Neurology, are the first of their kind, the study authors said. "One of the precursors of Alzheimer's is the development in the brain of proteins called amyloid and tau, which we refer to as the pathology of Alzheimer's," said the study's lead author, Jeremy Herskowitz. He's an assistant professor with the ... Read more
