Is Need for More Sleep a Sign of Pending Dementia?

Posted 1 day 1 hour ago by Drugs.com

WEDNESDAY, Feb. 22, 2017 – Seniors who begin sleeping more than nine hours a night may face a higher risk of dementia down the road, a new study suggests. The researchers estimated that the risk of dementia grew by almost 2.5 times for those who found themselves recently needing extra sleep. The chances of dementia rose sixfold for people without a high school degree who suddenly needed to sleep nine hours or more, the study contended. The study authors said this finding hinted that education might somehow offer a bit of protection from dementia. People with dementia often suffer from disrupted sleep, "but we don't know much about whether these changes come first," said study co-author Matthew Pase. He's a neurology fellow at the Boston University School of Medicine. Dementia "is by no means a certain fate" in those who find themselves sleeping longer as they age, Pase said. The new ...

Unhealthy in Middle Age, Dementia in Old Age?

Posted 1 day 1 hour ago by Drugs.com

WEDNESDAY, Feb. 22, 2017 – Middle-aged men and women at risk for heart disease may also face a higher chance of dementia later in life, a new study suggests. Risk factors such as smoking, high blood pressure and diabetes might boost the odds of dementia almost as much as carrying the gene that raises the risk of Alzheimer's disease, the researchers reported. "Most of these risk factors are treatable or preventable. And it is important to treat these vascular [circulatory system] risk factors starting at least in middle age, if not earlier," said lead researcher Dr. Rebecca Gottesman. She's an associate professor of neurology and epidemiology at Johns Hopkins University in Baltimore. Know your blood pressure, so it can be treated if it's high. Also, know if you have diabetes, so you can control and treat it. And stop smoking, Gottesman said. "These are important risk factors not only ... Read more

Can Air Pollution Heighten Alzheimer's Risk?

Posted 1 Feb 2017 by Drugs.com

WEDNESDAY, Feb. 1, 2017 – Air pollution may cause more than just lung disease: New research suggests that if tiny particles in the air from power plants and cars are inhaled, they might also invade the brain, increasing the risk for dementia. "Although the link between air pollution and Alzheimer's disease is a new scientific frontier, we now have evidence that air pollution, like tobacco, is dangerous to the aging brain," said study co-senior author Caleb Finch. He's with the University of Southern California's (USC) Leonard Davis School of Gerontology. For the study, the USC scientists collected samples of air particles with technology designed by university engineers. The researchers used the technology to expose female mice to air pollution. "Our state-of-the-art aerosol technologies, called particle concentrators, essentially take the air of a typical urban area and convert it to ... Read more

Busy Minds May Be Better at Fighting Dementia

Posted 31 Jan 2017 by Drugs.com

MONDAY, Jan. 30, 2017 – Mentally stimulating activities can protect your brain against aging, even if you're genetically predisposed toward dementia or Alzheimer's disease, a new study reports. Activities that keep the brain busy – using a computer, crafting, playing games and participating in social activities – appear to lower the risk of age-related mental decline in people 70 and older, the Mayo Clinic study found. "These kind of commonly engaged in, stimulating activities actually reduce the risk of people developing mild cognitive impairment," said co-author Dr. Ronald Petersen. He's director of the Mayo Clinic Alzheimer's Disease Research Center in Rochester, Minn. The researchers found the benefits of mental stimulation even helped people who have apolipoprotein E (APOE) E4, a genetic risk factor for dementia and Alzheimer's. For their study, Mayo researchers followed more ... Read more

Hospital-Related Delirium May Help Worsen Dementia

Posted 18 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 18, 2017 – Hospitalization-related delirium may speed mental decline in patients with dementia, a new study suggests. Delirium affects about one-fourth of older hospital patients and causes confusion and disorientation. British researchers looked at brain samples from nearly 1,000 people from the United Kingdom and Finland. They were 65 and older when they died. Records of their last 10 years of memory and thinking abilities, as well as episodes of delirium, were examined. Although the study couldn't prove cause and effect, the researchers found that memory changes were most severe among those with a history of hospital-related delirium and brain abnormalities indicating Alzheimer's disease or other types of dementia. "If delirium is causing brain injury in the short and long-term, then we must increase our efforts to diagnose, prevent and treat delirium. Ultimately, ... Read more

Does Living Near Major Roads Boost Dementia Risk?

Posted 5 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 4, 2017 – Want to cut your chances for Alzheimer's disease and other dementias? A new study suggests that picking a home far from major roadways might help. The Canadian study found that people who lived relatively close to busy traffic had a slightly higher risk for dementia. More specifically, this type of mental decline was more common among those who lived within about 160 feet of a major street, the study found. And the closer people lived to heavy traffic, the stronger the association. The research, published Jan. 4 in The Lancet, couldn't prove cause-and-effect, only an association, the researchers stressed. However, "our study suggests that busy roads could be a source of environmental stressors that could give rise to the onset of dementia," study author Hong Chen, with Public Health Ontario, said in a journal news release. One neurologist who reviewed the ... Read more

Was Football Safer Back in the Day?

Posted 12 Dec 2016 by Drugs.com

MONDAY, Dec. 12, 2016 – In a finding that suggests football used to be a less dangerous sport, a small study shows that men who played in high school in the 1950s and 1960s may not be at increased risk for dementia or memory problems. Nor did they show increased rates of Parkinson's disease or amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease. The study used a small group of men, the researchers acknowledged. But, they added, the results are in line with an earlier study that examined men who'd played high school football in the 1940s and 1950s. "What we can say is, for that era, football did not increase the risks of neurodegenerative disease compared with other sports," said senior researcher Dr. Rodolfo Savica, a neurologist at the Mayo Clinic in Rochester, Minn. That might sound surprising, given evidence that former professional football players can face ... Read more

Aerobic Exercise May Help Guard Against Dementia

Posted 30 Nov 2016 by Drugs.com

WEDNESDAY, Nov. 30, 2016 – Aerobic exercise may strengthen memory and thinking skills in older adults with mild cognitive impairment (MCI), a small study suggests. People with mild cognitive impairment are at increased risk for Alzheimer's disease. The study included 16 people, average age 63, who did aerobic workouts such as on a treadmill, stationary bike or elliptical training. They worked out four times a week for six months. There was also a control group of 19 people, average age 67, who did stretching exercises four times a week for six months but no aerobic activity. All of the participants had mild cognitive impairment. After six months, brain scans revealed that those in the aerobic exercise group had greater increases in brain volume than those in the stretching group, the researchers said. Those in the exercise group also showed significant improvement in thinking and ... Read more

Brain Scans May Improve Dementia Diagnosis, Treatment

Posted 8 Nov 2016 by Drugs.com

TUESDAY, Nov. 8, 2016 – Tens of millions of people worldwide suffer from memory loss and mental impairment due to dementia. While there's no cure, medication may temporarily improve some symptoms. Proper treatment, however, depends on identifying the type of dementia and early detection. A new study shows that MRI brain scans can help doctors tell which people with certain thinking and memory problems might go on to develop dementia with Lewy bodies rather than Alzheimer's disease. The researchers found that scans from people who eventually developed Lewy body dementia showed a lack of shrinkage in a portion of the brain related to memory, known as the hippocampus. "Identifying people with mild cognitive impairment at risk for dementia with Lewy bodies is critical for early interventions with the potential treatments emerging in the field," said study author Dr. Kejal Kantarci. She's a ... Read more

Study Links Disasters to Dementia

Posted 25 Oct 2016 by Drugs.com

TUESDAY, Oct. 25, 2016 – Earthquakes, floods and other natural disasters may raise dementia risk for seniors forced to leave their homes, a new study suggests. "In the aftermath of disasters, most people focus on mental health issues like PTSD," said study author Hiroyuki Hikichi, a research fellow at Harvard University's School of Public Health, in Boston. "But our study suggests that cognitive decline is also an important issue," Hikichi said in a university news release. Relocation to a temporary shelter after a disaster may have the unintended effect of separating people not just from their homes but from their neighbors – and both may speed up mental decline among vulnerable people, Hikichi's team noted. Researchers looked at nearly 3,600 survivors of the 2011 earthquake and tsunami in Japan. All were 65 and older. The rate of dementia in this group was 4.1 percent before the ... Read more

High Blood Pressure May Hike Dementia Risk

Posted 10 Oct 2016 by Drugs.com

MONDAY, Oct. 10, 2016 – High blood pressure, particularly in middle age, might open the door to dementia, the American Heart Association warns in a new scientific statement. Dementia affects some 30 million to 40 million people worldwide. That number is expected to triple by 2050, as the world's population ages and treatments remain elusive, the association noted. "People with high blood pressure tend to have more dementia," said statement author Dr. Costantino Iadecola. He is a professor of neurology and neuroscience at Weill Cornell Medical College in New York City. Whether controlling high blood pressure ("hypertension") reduces the odds of developing dementia, however, has not been scientifically proven, he said. "There are a lot of small observational studies that looked at people who were treated for blood pressure and, generally, there was an improvement in cognition [thinking ... Read more

Study Finds Fault With ICU Treatment of Dementia Patients

Posted 10 Oct 2016 by Drugs.com

MONDAY, Oct. 10, 2016 – A new study raises red flags about the use of ventilators among dementia patients in intensive care units. Researchers analyzed data from about 635,000 hospitalizations of U.S. nursing home patients with advanced dementia. Between 2000 and 2013, ventilator use among these patients, whose average age was 84, nearly doubled at the 2,600 hospitals studied. But more than 80 percent of the patients died within a year, the study found. The results suggest ventilators are being overused, leading to unnecessary patient suffering and higher health care costs, according to the authors of the study published Oct. 10 in the journal JAMA Internal Medicine. "These findings call for new efforts to ensure that the use of mechanical ventilation is consistent with patient's goals of care and their clinical condition," said corresponding author Dr. Joan Teno. She is a professor of ... Read more

Fallout From 9/11 May Include Early Dementia

Posted 30 Aug 2016 by Drugs.com

TUESDAY, Aug. 30, 2016 – The 9/11 attack on the World Trade Center continues to the ravage the minds of those who responded to the Twin Towers collapse, new research shows. Post-traumatic stress disorder (PTSD) experienced by many rescuers and other first responders now appears linked to mental decline and dementia, the study authors found. "People with PTSD, regardless from where they get it, are more likely to have cognitive impairment earlier," said lead researcher Sean Clouston, referring to memory and thinking abnormalities. About one-fifth of the World Trade Center responders developed PTSD, according to background notes with the study. "World Trade Center PTSD is associated with potential cognitive impairment, and cognitive impairment is a risk factor for dementia," said Clouston, an assistant professor of family population and preventive medicine at Stony Brook University in ...

Even a Little Exercise May Help Stave Off Dementia

Posted 26 Aug 2016 by Drugs.com

FRIDAY, Aug. 26, 2016 – Couch potatoes have a higher risk of developing dementia in old age, a new study reports. Seniors who get little to no exercise have a 50 percent greater risk of dementia compared with those who regularly take part in moderate or heavy amounts of physical activity, the researchers found. Moderate physical activity can include walking briskly, bicycling slower than 10 miles an hour, ballroom dancing or gardening, according to the U.S. Centers for Disease Control and Prevention. "It doesn't require intensive physical activity to decrease risk of dementia," said senior researcher Dr. Zaldy Tan. He is medical director of the Alzheimer's and Dementia Care Program at University of California, Los Angeles. "Even moderate amounts are fine." Study participants aged 75 or older gained the most protective benefit from exercise against the onset of dementia, the findings ... Read more

Acupuncture May Slow Pre-Dementia Memory Loss: Study

Posted 5 Aug 2016 by Drugs.com

THURSDAY, Aug. 4, 2016 – Acupuncture may benefit people who have memory loss, but don't yet have dementia, suggests a review by Chinese researchers of five earlier studies. Nothing has yet been proven to halt the progression to dementia in those who are destined to progress. But, acupuncture used alone or along with another treatment, such as the medication nimodipine, might help retain some memory function, the researchers said. But several doctors not involved with the review said it was too soon to say that acupuncture might be effective against dementia. For the study, Min Deng and Xu-Feng Wang, from Wuhan University in China, reviewed five previously published studies done in 2012 and 2013. The trials included nearly 600 people with mild cognitive impairment, a type of memory loss that's considered pre-dementia. About 5 percent to 10 percent of people with mild cognitive ... Read more
