Taking More Naps Can Be Sign Of Alzheimer’s Disease

Taking More Naps Can Be Sign Of Alzheimer’s Disease A new study found that the people who frequently take naps may already be developing Alzheimer’s disease.

Scientists believe even moderate amounts of exercise can slow cognitive decline in people at risk of developing Alzheimer ' s disease . A study published in the journal JAMA Neurology found a total of around 8,900 steps per day appeared to slow rates of cognitive decline and brain volume loss in

“This is only slightly less than the 10, 000 many of us strive to achieve daily.” Dr Jasmeer Chhatwal said: “One of the most striking findings from our study Dr James Pickett, from the Alzheimer ’ s Society, said the study adds to previous research showing the benefits of exercise . But he added: “This can

Researchers have investigated whether working out affects levels of a biomarker linked to Alzheimer's disease. Scientists believe even moderate amounts of exercise can slow cognitive decline in people at risk of developing Alzheimer's disease.

A study published in the journal JAMA Neurology found a total of around 8,900 steps per day appeared to slow rates of cognitive decline and brain volume loss in people who were at high risk. The individuals were considered at risk because of the levels of amyloid beta—a protein thought to play a role in Alzheimer's— in their brain.

Study shows Apple devices in combo with apps could identify dementia Drugmaker Eli Lilly said on Thursday early results from a study suggest that Apple Inc devices, including the iPhone, in combination with digital apps could differentiate people with mild Alzheimer's disease dementia and those without symptoms. © Karl Tapales/Getty Images The study, tested in 113 participants over the age of 60, was conducted by Apple along with Eli Lilly and Evidation Health. The Apple devices were used along with the Beddit sleep monitoring device and digital apps in the study. The researchers looked at device usage data and app history of the study participants over 12 weeks.

Exercise may improve cognition and prevent Alzheimer ' s disease , but are some forms of exercise better than others? New research investigates. Overall, the analysis included 1,145 seniors who were at risk of Alzheimer ' s either because one of their parents had been diagnosed with the illness

Regular exercise is your best bet for preventing Alzheimer ' s disease and improving cognitive function. More research is needed to know to what degree adding physical activity improves memory or slows the progression of cognitive decline.

Dr. JasmeerChhatwal, Assistant Professor at Harvard Medical School and co-author of the research, told Newsweek: "These results suggest that very achievable levels of physical activity may be protective in those at high risk of cognitive decline and that this effect can be augmented further by lowering vascular risk." Vascular risk factors include high blood pressure, obesity, smoking, diabetes, he explained.

"These results underscore that there are likely to be factors that we can modify to reduce the risk of cognitive decline, even if there is already evidence of build-up of the amyloid protein," he said.

Even a Small Boost in Exercise Can Help Protect You From Alzheimer’s

Even a Small Boost in Exercise Can Help Protect You From Alzheimer’s You don’t even need to hit 10,000 steps a day, research suggests.

Taking 10, 000 steps per day is often suggested as a desirable exercise goal for people who wish to But a new study of postal workers in Scotland suggests that that number could be too conservative and This study was one of the first to persuasively show that being physically active could lower

“Six thousand steps and above is getting you into that range of what these studies are showing and is protective against cardiovascular disease One of the major problems with the 10, 000 - steps - a - day goal is that it doesn’t take into account the intensity of exercise . Getting out of breath and increasing

The authors of the paper studied 182 people who were healthy when the study launched. The participants were involved in the Harvard Aging Brain Study, and had their cognition measured annually, and their brain volume approximately every three years for a period of seven years. Researchers told the participants to wear a pedometer for 7 days when they were awake, so they could document how many steps they took.

Researchers used positron emission tomography (PET) imaging to scan the brains of the participants for the amyloid beta protein. Their heart disease risk was also calculated by noting factors including their sex, BMI, blood pressure, whether they had diabetes, and if they smoked.

Past studies involving animals and humans have suggested exercise can preserve gray matter in the brain and prevent the buildup of amyloid beta, and the tau protein also linked to Alzheimer's, the authors wrote.

High Cholesterol Linked to Alzheimer's Disease

High Cholesterol Linked to Alzheimer's Disease Scientists believe early-onset Alzheimer’s is associated with cholesterol genes.

That is the familiar face of Alzheimer ’ s , the withered person with the scrambled mind marooned in a nursing Was she simply a woman with Alzheimer ’ s , limited to backward glances, or could this be a new Many think of Alzheimer ’ s as a memory disease , but its awful mysteries involve more than that.

Study : Gum disease linked to Alzheimer ' s . A 2017 study out of Taiwan found that people with chronic gum disease lasting 10 years had a 70 percent increased risk for developing Alzheimer ' s . One Chilean city was flooded with more than 300, 000 visitors to see the moon completely hide the

"Many people may be able to achieve the levels of activity seen here without major changes to their schedules," said Chhatwal.

However he said the results are limited because the team only measured physical activity at the start of the study and for just a week. What's more, the pedometers did not measure the intensity or the type of physical activity in which participants engaged. "We plan to address these questions in future research," Chhatwal said.

Still, as there are currently no drugs that treat Alzheimer's disease, it is important to find other ways we can alter the course of the disease, he argued.

Dr. James Pickett, head of research at the charity Alzheimer's Society, told Newsweek: "This study adds to previous research showing that people who are more active have a slower reduction in their memory and thinking skills as they get older, lose fewer brain cells, and have less amyloid, a hallmark of Alzheimer's disease, in their brain.

"However, this can only show us that levels of physical activity are linked to brain measures—it doesn't tell us that increasing activity would reduce your risk of getting dementia. There are ongoing trials to see if increasing activity can prevent cognitive decline and dementia, and we eagerly await these results—prevention is key, which is why we're funding a variety of studies to better understand the different risk factors for dementia.

How Exercise Lowers the Risk of Alzheimer’s by Changing Your Brain

How Exercise Lowers the Risk of Alzheimer’s by Changing Your Brain Researchers analyzed brain changes linked to exercise to better understand how physical activity can slow the cognitive decline of Alzheimer’s

Exercise is good for everyone, including those with Alzheimer ’ s disease . It might slow down the disease while improving memory and mood, a 6-year-long study shows . It also stimulates the senses, creates a sense of purpose, and can be a rich source of memories for people who love plants.

Studies show that exercise can treat mild to moderate depression as effectively as antidepressant medication—but without the side-effects, of course. As one example, a recent study done by the Harvard T.H. Chan School of Public Health found that running for 15 minutes a day or walking for an

Watch: 10 Facts About Alzheimer's

Dr. Jana Voigt, head of research at the charity Alzheimer's Research UK, told Newsweek: "This study only measured daily step counts over a week, so we don't know how physically active people were throughout their lives. Future studies using long-term physical activity data could shed more light on the link between physical activity and brain health.

"While research to find new treatments to slow or stop the diseases that cause dementia continues, it is also important that we understand ways to help people reduce their risk. Whether it's walking the dog, going for a swim or hitting the gym, the key to keeping physically active is to do things you enjoy and will stick to long-term."

She advised: "While there is no sure-fire way to stave off dementia, you can also support brain health by eating a healthy diet, only drinking within recommended limits, staying mentally active, keeping weight and cholesterol in check, and not smoking."
