Heart Disease, Alzheimer's Linked by Common Risk Factors

Posted 1 day 18 hours ago by

TUESDAY, July 28, 2015 – Some risk factors for heart disease may also be linked with Alzheimer's and other types of dementia, a new study reports. "We already know that vascular risk factors damage the brain and can result in cognitive [mental] impairment," study lead author Dr. Kevin King said in a news release from the journal Radiology. "Our findings give us a more concrete idea about the relationship between specific vascular risk factors and brain health," said King, an assistant professor of radiology at the Keck School of Medicine at the University of Southern California, Los Angeles. The study was published in the July 28 issue of the journal. Prior research has linked heart risk factors and mental decline, but this study focused on specific risk factors and three brain structures – the hippocampus, precuneus and posterior cingulate cortex – that play a role in memory. The ... Read more

Dementia Risk May Be Dropping With Generations

Posted 6 days ago by

FRIDAY, July 24, 2015 – New research suggests that people born after 1930 may have a lower risk of developing dementia than the generation before them, adding to evidence that the incidence of dementia may be declining in the United States and elsewhere. That decline was not explained by age, but did seem to be related to improvements in heart health over time, the researchers found. The study, of nearly 1,000 elderly New Yorkers, found that those born after 1930 had a lower risk of dementia than those born between 1916 and 1930. In the older group, people developed dementia at a rate of 2.2 percent per year between 1993 and 2014, when they were in their 70s and beyond, said lead researcher Carol Derby, an associate professor of neurology at the Albert Einstein College of Medicine, in New York City. In the younger group, that rate was just over 0.4 percent per year, Derby added. "We ... Read more

Pain Often Hinders Seniors With Dementia

Posted 8 days ago by

WEDNESDAY, July 22, 2015 – Elderly Americans with dementia who live at home may need help managing their pain, a new study suggests. "As a hospice nurse caring for people in their homes, I have seen many patients with dementia who suffer from distressing pain," said study author Lauren Hunt, a physiological nursing Ph.D. student at the University of California, San Francisco, School of Nursing. "I was motivated to conduct this research study to understand the issue from the broader national prospective. It turns out that pain is very common in this population and is frequently severe enough to limit activities," she said in a university news release. Hunt's team analyzed data gathered in 2011 from more than 800 Medicare enrollees, aged 65 and older, who had dementia but still lived at home. Sixty-four percent of them had bothersome pain, and about 43 percent had pain that limited their ... Read more

Women Descend Into Alzheimer's at Twice the Speed of Men: Study

Posted 9 days ago by

TUESDAY, July 21, 2015 – Women with mild thinking and memory problems – known as mild cognitive impairment – deteriorate twice as fast mentally as men with the same condition, according to new research. Mild cognitive impairment isn't severe enough to interfere with daily life, but it is linked to higher odds of developing Alzheimer's disease or another type of dementia, the researchers said. "Our findings do suggest greater vulnerability in women with mild cognitive impairment stage, which is more severe than normal memory loss and is an intermediary stage between aging and dementia," said lead researcher Katherine Lin, a clinical research scholar at Duke University in Durham, N.C. Several factors may account for this increased vulnerability among women, Lin added. Women may be genetically predisposed to developing more plaque in the brain, which is a hallmark of Alzheimer's, or ... Read more

Type 1 Diabetes Linked to Higher Risk of Dementia

Posted 10 days ago by

MONDAY, July 20, 2015 – People with type 1 diabetes may face a greater risk of developing thinking and memory problems as they age compared to the general population, new research suggests. The study found that people with type 1 diabetes were 83 percent more likely to develop dementia as seniors. "Our study found a modestly higher risk of all-cause dementia in people with type 1 diabetes. The next step is to figure out what that means, and how we can help people with type 1 diabetes age successfully," said study author Rachel Whitmer, a senior scientist in the division of research at Kaiser Permanente in Oakland, Calif. However, Whitmer also noted that the study doesn't prove that type 1 diabetes caused dementia, only that the two diseases were linked. "This is an observational study that shows association, not causation. We don't have tissue from these people's brains," she added. ... Read more

Brain Changes Differ by Race With Alzheimer's Disease: Study

Posted 15 days ago by

WEDNESDAY, July 15, 2015 – Alzheimer's disease seems to develop differently in the brains of black patients than in whites. And, black people seem more likely to suffer different types of brain changes that also contribute to dementia, a new study reports. Alzheimer's disease dementia is generally associated with a build-up of substances known as plaques and tangles inside the brain. But, there are other brain changes that can also contribute to dementia, the study authors noted. For example, the brains of people with dementia sometimes contain infarcts – tiny areas of dead tissue caused by micro-strokes, the researchers explained. They also might contain Lewy bodies – another form of abnormal protein build-up in the brain that's usually associated with Parkinson's disease. Autopsies of black and white Alzheimer's patients revealed that blacks were more likely than whites to ... Read more

Human Brain Has Nearly Ideal Network of Connections, Research Shows

Posted 15 days ago by

WEDNESDAY, July 15, 2015 – A new study examining why the human brain evolved the way it did could lead to new ways to treat brain disorders, researchers say. The brain developed into its present form to speed transfer of information from one region of the brain to another, so people can perform at peak capacity, according to Dmitri Krioukov, an associate professor of physics at Northeastern University in Boston, and colleagues. The investigators found that the brain's structure contains an almost perfect network of connections. The researchers first created a map of a brain network that provided the best transfer of information between brain regions. They compared this "idealized" map with the brain's actual network and found that they were 89 percent similar. The study was published recently in the journal Nature Communications. Along with shedding new light on the brain's evolution, ... Read more

Uncontrolled Diabetes May Boost Dementia Risk

Posted 9 Jul 2015 by

THURSDAY, July 9, 2015 – Diabetes patients with high rates of complications from the disease may face increased risk for dementia, a new study suggests. "We found that as diabetes progresses and an individual experiences more complications from the disease, the risk of dementia rises as well," wrote Dr. Wei-Che Chiu, of the National Taiwan University College of Public Health, in Taipei. Better blood sugar control can help prevent the mental decline associated with diabetes, he and his colleagues said. They examined data from more than 431,000 people in Taiwan who were older than 50 and newly diagnosed with diabetes. Complications of diabetes include vision loss, kidney failure and nerve damage. Over 12 years of follow-up, more than 6 percent of the patients were diagnosed with dementia. Those with a greater number of diabetes complications were at higher risk for mental decline than ...

Alzheimer's-Linked Brain Plaques May Arise Decades Before Symptoms

Posted 19 May 2015 by

TUESDAY, May 19, 2015 – Abnormal protein clumps may appear in the brain up to 30 years before people develop Alzheimer's disease, a new study estimates, perhaps providing a window of opportunity to intervene. Scientists have long known that people with Alzheimer's disease show brain "plaques," where pieces of a protein called amyloid abnormally clump together. The new study, published May 19 in the Journal of the American Medical Association, confirms that brain plaques become increasingly common as people age – even when memory and thinking are still intact. However, at all ages, plaques are more common among people with risk factors for Alzheimer's. That includes people who already have milder memory problems, and those who carry a gene variant – APOE4 – that boosts risk for Alzheimer's, the most common form of dementia. But, the study authors estimate those brain plaques may ... Read more

Serious Concussions Linked to Memory Problems in Retired NFL Players

Posted 18 May 2015 by

MONDAY, May 18, 2015 – National Football League players who suffered concussions serious enough to lose consciousness may be at risk for brain damage that can affect memory later in life, a new study suggests. Specifically, concussions may damage the hippocampus, the brain's memory center. For reasons that are not well understood, a concussion – particularly when accompanied by loss of consciousness – causes this area of the brain to shrink, which in turn causes memory problems, the researchers said. "These findings serve as a potential risk factor for mental changes later in life," said lead researcher Munro Cullum, a neuropsychologist at the University of Texas Southwestern Medical Center in Dallas. "We don't know how much the risk is increased," Cullum said. "We also can't predict who is going to have memory problems." Cullum noted that a concussion with loss of consciousness may ... Read more

'Medical Marijuana' Pill Falls Short in Dementia Study

Posted 13 May 2015 by

WEDNESDAY, May 13, 2015 – So-called medical marijuana pills may not ease the common behavioral symptoms that affect people with dementia, a small study suggests. In a trial of 50 dementia patients, researchers found that pills containing the main active ingredient in marijuana were no better than placebo pills in easing agitation, aggression and wandering. However, that doesn't mean the approach is a failure, the investigators report in the May 13 online edition of Neurology. The researchers say the medical marijuana pills were well-tolerated, so it seems safe to test a higher dose in future studies. The lack of side effects suggests the dose was too low, according to Dr. Marcel Olde Rikkert and his colleagues at Radboud University Medical Center, in the Netherlands. In the United States, more than 5 million people have Alzheimer's disease, the most common form of dementia, according ... Read more

Healthy Eating May Shield the Aging Brain

Posted 6 May 2015 by

WEDNESDAY, May 6, 2015 – People who eat plenty of fruits and veggies may preserve more of their memory and thinking skills as they grow old, a new large study suggests. The findings, published online May 6 in the journal Neurology, add to a growing body of evidence linking healthy eating habits to a lower risk of dementia. Researchers found that among nearly 28,000 older adults from 40 countries, those who scored in the top 20 percent on a "healthy eating" scale were less likely to show declines in memory, attention and other mental skills over the next five years. Compared with older adults who favored foods like red meat and sweets, the risk of mental decline for the healthiest eating group was about one-quarter lower. Among the people with the healthiest diet, about 14 percent showed declines in thinking, compared to about 18 percent of those with the least healthy diets. The study ... Read more

Depression Plus Diabetes May Boost Dementia Risk

Posted 15 Apr 2015 by

WEDNESDAY, April 15, 2015 – Depression and diabetes are each hard on the brain, and having both conditions may significantly raise the risk of dementia, according to new research. "What this argues for is, we need to do a better job of both identifying diabetes and depression and then really treating them once identified," said study researcher Dr. Dimitry Davydow, an associate professor of psychiatry and behavioral sciences at the University of Washington School of Medicine in Seattle. His team looked at dementia risk among 2.4 million people in Denmark, age 50 and older, who had depression, type 2 diabetes or both, and compared them with people who had neither condition. The researchers also took into account pre-existing medical conditions, such as cerebral vascular problems, complications such as kidney problems and other ailments. "Even after taking those into account, diabetes ... Read more

To Protect Your Aging Brain, Start With Exercise

Posted 14 Apr 2015 by

TUESDAY, April 14, 2015 – There are things people can do to preserve their brain function as they age, a report released Tuesday from the Institute of Medicine (IOM) suggests. "Changes in mental functions and capabilities are a part of aging and occur with everyone," report committee chair Dan Blazer, a professor of psychiatry emeritus at Duke University Medical Center in Durham, N.C., said in an IOM news release. "The extent and nature of these changes vary widely and are gradual, and aging can have both positive and negative effects on cognition [thinking skills]. Wisdom and knowledge can increase with age, while memory and attention can decline," he said. But the committee said there are things people can do to promote brain health. These include being physically active, and reducing and managing heart disease risk factors such as high blood pressure, diabetes and smoking. It's also ... Read more

Could Obesity Help Protect Against Dementia?

Posted 10 Apr 2015 by

THURSDAY, April 9, 2015 – A new study of nearly 2 million people suggests that those who are overweight or obese in middle age may be less likely to develop dementia than their normal and underweight peers. Overweight and obese people were about 30 percent less likely to develop dementia 15 years later than people of a healthy weight. Conversely, underweight people were 34 percent more likely to develop dementia than those whose weight was normal, according to the study authors. "Our findings were unexpected, that obese and overweight people would be protected," said lead researcher Dr. Nawab Qizilbash, from OXON Epidemiology Ltd. in Madrid, Spain. However, the retrospective study was only able to show an association between obesity and a reduced risk of dementia, not a cause-and-effect relationship. And Qizilbash added that people shouldn't take these preliminary findings as a license ... Read more
