Alzheimer’s disease research - awareness, education and care (Spring, 2011)

May 27, 2011

One caregiver in an education and training group led by the research team of Peggye Dilworth-Anderson, PhD, thought her mother’s memory loss was the result of worrying too much. “We just thought maybe it was the stress of the job and some family issues.”

Another said of her father, “He’s getting older. Maybe it’s normal. You know, it happens. You get more absent-minded.”

In both cases, aging parents were diagnosed with Alzheimer’s disease, a neurodegenerative illness that is very different from normal aging. An estimated 5.4 million people have Alzheimer’s, a form of dementia that is the sixth leading cause of death in the U.S., the only killer in the top 10 for which there is no means to slow or stop its progress.

As great a toll as the disease takes on the people who have it, an equal burden is borne by those who give them care. According to the Alzheimer’s Association (www.alz.org), nearly 15 million Alzheimer’s and dementia caregivers provide 17 billion hours of unpaid care, valued at $202 billion. That level of stress takes its toll on caregivers’ health, and caregivers incurred $7.9 billion in additional health care costs in 2010. Sixty percent of family caregivers report high levels of stress, and 33 percent report being depressed.

Providing help for dementia caregivers is at the heart of Dilworth-Anderson’s research and community engagement. Professor of health policy and management at UNC’s Gillings School of Global Public Health and interim co-director of the UNC Institute on Aging, Dilworth-Anderson aims to reduce and eliminate health disparities related to Alzheimer’s disease. She and her team are discovering ways to integrate research and education to empower North Carolina communities to care for older adults throughout the state, and for the family members and other volunteers who look after them.

In particular, Dilworth-Anderson and her team focus on the needs of those with limited access to health resources and those whose health literacy (or ability to obtain and understand basic health information and services) is limited. Many live in rural areas, which may result in further barriers to health care.

“Our research team works to understand the challenges of caring for older adults with dementia, the role of culture in shaping the caregiving experience, and what this provision of care actually means to caregivers and their families,” Dilworth- Anderson says. “Three of our recent studies have provided insight into how caregivers perceive dementia, their level of knowledge about the disease, and resources and services available to patients and caregivers.”

Dilworth-Anderson’s “Perceiving and Giving Meaning to Dementia” study surveyed 85 people from 25 racially and ethnically diverse North Carolina families to examine the influence of cultural values upon perceptions about dementia caregiving and health care access. The study found that most caregivers mistook early signs of dementia for normal behavior. Coping also was determined to be a dynamic process, often handled differently according to culture.

In the “Cultural Meanings and Reasons for Dementia Caregiving” study, a telephone survey of 200 caregivers was intended to uncover cultural and personal reasons why caregivers provide care to their older relatives. The study found that caregivers accepted their role because of family values and community expectations. They reported seeing themselves as being available, responsible and compassionate.

“Train the Trainer: A Dementia Care Project” is aimed not only at understanding caregiver dynamics but also at providing caregivers with information and education about dementia and normal aging and introducing available resources and strategies for self-care and stress management. Caregivers, who learned through the training how to recognize signs of dementia, are continuing to share the information within their respective communities.

Among their insights? “I need to try to stay positive – stay in good health so I will have strength and energy to be the caregiver I should be,” one person told Dilworth- Anderson. “I have to laugh more, and be more of the mindset to be in the moment with my mom,” another told her.

To date, 443 caregivers in North Carolina have participated in the project.

Dilworth-Anderson and her team currently are conducting town hall meetings to promote awareness and disseminate dementia care information to further empower rural and medically underserved communities in the state.

About 170,000 North Carolinians had been diagnosed with Alzheimer’s in 2010; by 2025, the number is expected to rise to 210,000. AARP estimates that there are 357,000 unpaid caregivers (family members and friends) for people with Alzheimer’s disease in our state.

Traditions and culture in North Carolina – especially in rural areas and small towns and among African-American families – influence people to care for their family members themselves, Dilworth-Anderson said. “It’s kind of a tradition in our family,” one caregiver told her. “We take care of each other.”

Another explained, “She’s my mother, and I love her and respect her. She raised me, and now it’s my time to give back to her.” Dilworth-Anderson says it is very rewarding to be able to help older adults and their caregivers cope better with the challenges of dementia.

She will continue to conduct this type of work, she says, “because as a scientist, I know that research findings, when translated, disseminated and applied well, can have a positive influence on older people with dementia, their family caregivers and friends who help care for them.”

Caregiver guides from the project are available on the website of the UNC Institute on Aging (www.aging.unc.edu).

Dilworth-Anderson, past president of the Gerontological Society of America and recipient of the Ronald & Nancy Reagan Research Award in Alzheimer’s Research, has received support from the Alzheimer’s Association, GlaxoSmithKline Community Partnership Program, Agency for Health Care Research and Quality, and the National Institute on Aging.
