Older Adults Who Have Slower Walking Speeds May Have Increased Risk for Dementia

Journal of the American Geriatrics Society Research Summary

As of 2015, nearly 47 million people around the world had dementia, a memory problem significant enough to affect your ability to carry out your usual tasks. The most common cause of dementia is Alzheimer’s disease, but other forms exist, too.

Because there’s currently no cure for dementia, it’s important to know about the risk factors that may lead to developing it. For example, researchers have learned that older adults with slower walking speeds seem to have a greater risk of dementia than those with faster walking speeds. Recently, researchers from the United Kingdom teamed up to learn more about changes in walking speed, changes in the ability to think and make decisions, and dementia. They published their study in the Journal of the American Geriatrics Society.

The researchers examined information collected from the English Longitudinal Study of Aging. The study included adults aged 60 and older who lived in England. In their study, the researchers used information collected from 2002 to 2015. They assessed participants’ walking speed on two occasions in 2002-2003 and in 2004-2005, and whether or not the participants developed dementia after the tests from 2006-2015. Then, they compared the people who had developed dementia with those who had not. Continue reading

Helping Prevent Falls in Older Adults with Dementia

Journal of the American Geriatrics Society Research Summary

Annually, about one-third of all American adults aged 65 or older experience a fall. Falls are a major cause of medical problems, especially among those who have dementia. In fact, twice the number of older adults with dementia experience falls, compared to people without dementia.

What’s more, older adults with dementia or other cognitive problems who fall are five times more likely to be admitted to long-term care facilities, and are at higher risk for fractures, head injuries, and even death, compared to older adults without dementia who experience a fall.

Researchers have recently focused on the role that dementia and other cognitive problems may play in falling, in hopes of discovering ways to manage and prevent falls. They published their study in the Journal of the American Geriatrics Society. Continue reading

Dementia Increases the Risk of 30-Day Readmission to the Hospital After Discharge

Journal of the American Geriatrics Society Research Summary

About 25 percent of older adults admitted to hospitals have dementia and are at increased risk for serious problems like in-hospital falls and delirium (the medical term for an abrupt, rapid change in mental function). As a result, older adults with dementia are more likely to do poorly during hospital stays compared to older adults without dementia.

Until now, little was known about the effects of dementia on early hospital readmission. Researchers in Japan recently published the results of a study to learn more about the effects of dementia and being admitted to the hospital within 30 days of a previous hospital discharge (the medical term for leaving the hospital once your care is considered complete). Their study was published in the Journal of the American Geriatrics Society.

The researchers studied information from people 65-years-old and older who had been discharged from hospitals between 2014 and 2015, and then followed them for six months. The researchers were looking for unplanned readmissions to the hospital within 30 days of the patient’s discharge. Continue reading

End-of-Life Hospital and Healthcare Use Among Older Adults with Alzheimer’s Disease

Journal of the American Geriatrics Society Research Summary

Because people are now living longer and often healthier lives, the rate of some illnesses that are more likely to develop with age has risen. These illnesses include dementia. In fact, the number of us living with dementia was already 47 million worldwide in 2015. It could reach 131 million by 2050.

Dementia is a general term that includes different types of mental decline. The most common type of dementia is Alzheimer’s disease, which accounts for 60 to 80 percent of all dementia cases.

As Alzheimer’s disease worsens, older adults may become more likely to have trouble performing daily activities, can develop trouble swallowing, and may become less active. This increases the risk for other concerns like infections. These infections, such as pneumonia, can increase the risk for death. As a result, the cause of death for people living with Alzheimer’s disease is often infections or some other cause, rather than the Alzheimer’s disease itself.

A team of researchers from Belgium recently studied how people with Alzheimer’s disease use medical services during their final months. The goal was to learn more about the best ways to help older adults with dementia at the end of their lives. Their study was published in the Journal of the American Geriatrics Society. Continue reading

Aerobic Exercise May Mildly Delay or Slightly Improve Alzheimer’s Disease Symptoms

Journal of the American Geriatrics Society Research Summary

Alzheimer’s disease (AD) is a brain disorder that destroys memory and thinking skills over time. It is the most common form of dementia in older adults.  There is presently no cure for the condition, though treatment options are available. Today, some 5.3 million Americans live with AD, and it is now the sixth leading cause of death in the United States. The number of older adults who will develop AD is expected to more than triple by 2050.

Geriatrics experts have suggested that exercising can improve brain health in older adults. The World Health Organization (WHO) has recommendations for how much older adults should exercise. They suggest that older adults perform 150 minutes a week of moderate exercise (such as brisk walking), 75 minutes a week of vigorous aerobic training, or a combination of the two types. The WHO also recommends older adults perform muscle-strengthening exercises on at least two or more days a week.

However, not all studies of exercise and older adults have proven the benefits of exercise. We don’t know for sure whether exercise slows mental decline or improves older adults’ ability to think and make decisions. Continue reading
