Hearing and Vision Loss May Speed Development of Cognitive Problems

Journal of the American Geriatrics Society Research Summary

Cognitive decline ranges in severity from mild cognitive impairment (MCI) to Alzheimer’s disease and related dementias (ADRD). It is marked by memory loss and difficulty thinking and making decisions. Cognitive decline is a significant, common challenge to older adults’ well-being and their ability to live independently.

Today, cognitive impairment and ADRD are major global public health and social concerns as the population of older adults rises around the world. By 2050, more than 152 million people will be affected by these conditions. That’s why many countries, including the United States, see the prevention of ADRD as a key public health priority and are studying programs to help stem these diseases.

One way to prevent cognitive impairment and ADRD is to treat the problems that raise the risk for developing them. Two of these risk factors are hearing and vision loss. Currently, about 60 percent of people aged 70 years or older are affected by hearing loss, 40 percent are affected by vision loss, and 23 percent of older adults have both vision and hearing loss. Some studies have suggested that having both hearing and vision loss may be linked to poorer cognitive function or to a faster rate of cognitive decline.

However, more specific studies are needed to obtain more accurate information about these two sensory problems and their relationship to cognitive decline, suggests a  research team that examined the associations between having loss of one sensory function — hearing or vision — and cognitive decline, as well as the associations between having both types of sensory loss and cognitive decline. They published their findings in the Journal of the American Geriatrics Society. Continue reading

Delirium Screening in Skilled Nursing Facilities

Journal of the American Geriatrics Society Research Summary

Delirium and Alzheimer’s disease and related dementias (ADRD) can play a role in the mental decline of older adults who enter skilled nursing facilities (SNFs) for rehabilitation after being hospitalized. Healthcare practitioners may mistake these conditions for each other or even overlook them, even though they are distinct conditions and require different treatments.

Delirium is a term that means “sudden confusion. ” It is an abrupt, rapid change in mental function that goes well beyond the typical forgetfulness of aging. Delirium is a result of abnormal functioning of the brain and requires the attention of a healthcare professional.

On the other hand, ADRD is a progressive and chronic decline in your cognitive abilities. You can have delirium and ADRD at the same time. In fact, new research reveals that delirium is a strong predictor of new ADRD cases. About 15 percent of older adults admitted to SNFs after being hospitalized have delirium, and patients with delirium have a nearly 13 percent increased risk of receiving a new diagnosis of ADRD over the next four years.

Delirium and ADRD can be difficult for healthcare practitioners to tell apart, and older adults can have both conditions at the same time. However, the two conditions have not been studied together in older adults admitted to skilled nursing facilities.

In order to learn more about the relationship between delirium detection and a potentially premature or inappropriate diagnosis of ADRD, researchers conducted a study. They based their findings on their examination of Medicare data from 2011-2013 for new nursing home admissions. The study was published in the Journal of the American Geriatrics Society.

Healthy Lifestyle Habits May Lower the Risk for Developing Dementia

Journal of the American Geriatrics Society Research Summary

Can your eating habits and physical and mental activity lower your risk for developing dementia as you age? Obviously, it is important to learn all we can about how health habits affect the risks for developing dementia, a debilitating decline in memory and other mental abilities. Experts say that the number of people with dementia worldwide is expected to rise to 82 million by 2030 and to over 152 million by 2050.

A team of researchers designed a study to learn more about whether adopting healthier lifestyle habits can help prevent or slow the onset of dementia. Their study was published in the Journal of the American Geriatrics Society.

The researchers suggest that prevention strategies should focus on lowering dementia risk for people who are starting to experience cognitive decline, specifically subjective cognitive decline (SCD) and mild cognitive impairment (MCI). Continue reading

Does Having Alzheimer’s Disease and Dementia Affect Severity of Delirium?

Journal of the American Geriatrics Society Research Summary

Forms of dementia, including Alzheimer’s disease, gradually affect your cognitive function by harming your memory and your ability to think and make decisions. By 2050, experts project that 13.8 million older adults in the United States will develop Alzheimer’s disease and related Dementias (ADRD). Although Alzheimer’s disease is the most common form of dementia, other forms include Lewy Body dementia, frontotemporal dementia, and vascular dementia—all of which have upsetting consequences for people with dementia and their families.

Since no cure or treatment yet exists for ADRD, healthcare providers currently focus on preventing the treatable risk factors that can lead to dementia. This strategy could potentially slow the onset and progression of ADRD.

Hospitalization poses risks to people with ADRD and can have life-threatening consequences, including predisposing us to delirium (the medical term for a rapid change in mental state, often marked by confusion), a decline in mental or physical function, being admitted to long-term care facilities, and even death.

In particular, delirium can worsen the course of an illness, quicken physical and mental decline, lengthen hospital stays, and cause higher rates of hospital re-admission and death. One in 8 hospitalized people with ADRD who develops delirium will have at least one serious problem, including cognitive decline, possibly leading to admission to long-term care or death.

Here’s the good news: Experts say 30 to 40 percent of delirium cases are preventable. But until now, we have not studied how delirium and its severity affect hospitalized older adults with and without ADRD. Continue reading

A Creative Way to Expand the Geriatrics Workforce

Journal of the American Geriatrics Society Research Summary

Geriatrics is the field of health care focused on care for older adults. Experts suggest that our current geriatrics workforce needs better preparation to care for the 5.7 million people living with dementia in this country. To help meet this challenge, the Institute of Medicine has called for enhancing educational and training programs for improving the competence of the workforce, and to ensure that our workforce reaches the level needed to serve the growing population of older adults with dementia.

Despite these ongoing efforts, the shortage of geriatricians makes it difficult to meet these urgent educational needs. For this study, a team of researchers looked “outside the box” to learn more about whether creative solutions could offer valuable opportunities for addressing these issues. In this new study, the researchers outlined the results and outcomes of an undergraduate service-learning course that used music and filmmaking to teach person-centered approaches to dementia.

The course, which included music, filmmaking, and reflective writing components, focused on service at local dementia care settings and was conducted in collaboration with Music & Memory, a non-profit organization dedicated to bringing personalized music playlists to people living with dementia or other serious medical challenges.

The three-credit undergraduate service-learning course was developed and taught by a music professor over three consecutive semesters with 16 to 18 students each term.

The students worked in pairs at one of two dementia care settings. Students received initial classroom training on dementia, ethnomusicology (music anthropology), ethnographic fieldwork methods (the technical term for expert research based on studying people and culture), filmmaking basics, and creative aging.
