Exercise May Lessen Risk of Falling for Older Adults who have Alzheimer’s Disease and Mental Health Challenges

Journal of the American Geriatrics Society Research Summary

Alzheimer’s disease (AD) is a brain disease that causes changes that kill brain cells. AD is a type of dementia, which causes memory loss and problems with thinking and making decisions. People with AD and other forms of dementia have difficulties performing the daily activities others might consider routine.

Dementia takes a toll on those who live with it—and it also places a burden on caregivers. Along with problems connected to memory, language, and decision-making, dementia can cause neuropsychiatric symptoms, such as depression, anxiety, changes in mood, increased irritability, and changes in personality and behavior.  People who have AD/dementia also have twice the risk for falls compared to people without dementia. About 60 percent of older adults with dementia fall each year.

Researchers suggest that having neuropsychiatric symptoms might predict whether an older person with AD/dementia is more likely to have a fall. We also know that exercise can reduce the number of falls in older adults with dementia. However, we don’t know very much about how neuropsychiatric symptoms may increase the risk of falls, and we know even less about how exercise may reduce the risk of falls for people with dementia and neuropsychiatric symptoms. A research team decided to explore whether exercise could reduce the risk of falling among community-dwelling people with AD who also had neuropsychiatric symptoms. Continue reading

Older Adults with Strong Grip, Good Memory/Decision-Making Skills May Avoid or Delay Disability

Journal of the American Geriatrics Society Research Summary

As we age, we may develop certain disabilities that make it difficult to walk, climb, balance, or maintain our fine motor skills. In turn, these changes can affect our ability to perform routine, daily tasks, which can lead to a loss of independence and reduced quality of life. However, experts say that it is often possible to treat these difficulties before they lead to disability.

For example, having good muscle strength helps us maintain the ability to function well. Research suggests that a minimum level of strength is needed for good physical function. The stronger older adults are, the better able they may be to prevent future disability.

To learn more about how and whether being strong can ward off disability, a team of researchers examined information from a study called SHARE. It involved a survey of people aged 50 and older across most European Union countries and Israel every two years. This survey collected information about health, social and economic status, and participants’ social and family networks. A total of 30,434 people participated in this survey. The research team who studied the information from SHARE published their findings in the Journal of the American Geriatrics Society. Continue reading

Liver Transplant Survival Rate Sees Improvement Among Older Adults

Journal of the American Geriatrics Society Research Summary

An increasing number of older adults are diagnosed with end-stage liver disease. End-stage liver disease is a life-threatening condition in which the liver stops working normally. It can be caused by hepatitis, alcoholism, cancer, and other conditions. A liver transplant is the only treatment for end-stage liver disease.

Although older adults make up almost 24 percent of people waiting for liver transplants, they have often not been considered candidates for receiving this life-saving surgery. That’s because older adults often do poorly following liver transplant surgery. One reason for this is that older adults with liver disease often have many other health challenges which make recovery from transplant surgery more difficult.

However, researchers have recently reported successful liver transplants in older adults—even in people who are in their 80’s.

To learn more about older adults and liver transplants, a team of researchers studied information recorded by the Scientific Registry of Transplant Recipients (SRTR) from 2003 to 2016. The SRTR data system includes information about all liver donors, people on liver transplant wait lists, and people who have received transplants in the United States. The team’s study was published in the Journal of the American Geriatrics Society. Continue reading

Physical Activity Lowers Risk of Death from Heart Disease

Journal of the American Geriatrics Society Research Summary

Frailty is a health condition that increases risks of poor health, falls, disability, and death in older adults. Signs of frailty include weakness, weight loss, slow walking speed, exhaustion, and low levels of activity. As our population ages, scientists expect that more and more of us will need to address frailty and its associated health concerns.

Geriatrics is the branch of healthcare dedicated to working with older people. Geriatrics experts have suggested that physical activity may one of the best ways to prevent frailty.

Physical activity includes walking and other gentle forms of exercise. It is proven to improve health. Physical activity can lower the risk of many chronic diseases, including type 2 diabetes, heart disease, several cancers, and depression. Exercise also can improve your ability to perform your daily activities and can lower your risk of death from heart disease. In frail older adults, physical activity has been shown to improve strength, balance, agility (the ability to move quickly and easily), walking speed, and muscle mass (the amount of muscle you have in your body). These are all key functions tied to frailty.

Researchers recently reviewed a number of studies about exercise in frail older adults. The review found a number of studies that showed exercise helped reduce falls, improved walking ability, improved balance or increased muscle strength.  However, we still don’t know whether physical activity can reduce death among frail older adults.

Researchers recently designed a study to fill that knowledge gap by exploring whether physical activity could lower the high rate of death associated with frailty in older people. Their study was published in the Journal of the American Geriatrics Society. Continue reading

Does Open Heart Surgery Affect Cognitive Abilities?

Journal of the American Geriatrics Society Research Summary

Most people who need open heart surgery to repair damaged heart valves are aged 65 or older. The American Heart Association (AHA) estimates that nearly 8 million people have had heart surgeries. However, we don’t fully understand the effects of heart surgery on an older adult’s cognition (the ability to remember, think, and make decisions).

In 2014, an estimated 156,000 heart valve surgeries were performed in the US. The most common condition for valve surgery was aortic stenosis. The aorta is the heart valve that controls blood flow from your heart to the rest of your body. Aortic stenosis occurs when the aortic valve doesn’t allow blood to flow out of the heart properly. Adults 65 and older represent most of the people who need aortic valve surgery, and the number of older adults with aortic stenosis is expected to double by 2050.

Understanding how heart valve surgery may affect your cognition is important for older adults. To learn more, researchers reviewed studies to see how patients’ cognition changed before and after heart valve surgery. They also looked at whether surgeries on two types of heart valves, the mitral or the aortic, were associated with better or worse outcomes. Their study was published in the Journal of the American Geriatrics Society. Continue reading
