It happens quietly every day, in millions of homes around the country. People who get little recognition, no pay and few breaks.

They're caregivers, the family and friends who help people with Alzheimer's disease and other forms of dementia.

It can be a fulfilling, but challenging, role.

In a new poll, the vast majority of dementia caregivers — 85 percent — said it's a rewarding experience to care for a parent, spouse, family member or friend with cognitive issues and other dementia symptoms. In fact, 45 percent rated it as "very rewarding."

But a nearly equal number — 78 percent — also said it was somewhat or very stressful. Of those who called caregiving "very stressful," 40 percent also said it was not rewarding.

The poll also found that three-quarters of dementia caregivers don't take advantage of resources that can help.

Erica Solway, Ph.D., who helps direct the poll at the University of Michigan, says this needs to change, given the importance of the caregiver role.

"We can see that family caregivers need better support," she says. "Health care providers should ask their patients if they have caregiving responsibilities, and family and friends can offer to provide additional help so caregivers can take time for their own health and well-being.

As the population ages and the number of available caregivers is unlikely to keep pace, this will become more important."

Solway also says many resources exist for family and friends who care for people with dementia and other conditions. But it may be hard to know where to turn.

Here are some resources she recommends:

AARP

The poll's co-sponsor, AARP, offers a wide range of online and in-person services for dementia caregivers. It also has Prepare to Care guides in English, Spanish and Chinese for anyone planning to take on a caregiving role.

U-M's Program for Positive Aging

Michigan-based caregivers can come to a training session Nov. 20 in Ann Arbor that will help them recognize, anticipate and respond to the behavioral aspects of dementia.

U-M's Alzheimer's Disease Center

Caregivers from southeast Michigan can take part in the center's Wellness Initiative events and a Mindfulness Based Dementia Care course. The center also has a calendar of events in the area for dementia caregivers and the people they care for.

The Alzheimer's Association

The Alzheimer's Association devotes an entire section of its website to caregivers, including an online discussion forum and a quick "stress check" quiz. State and regional chapters of the association also have websites with information about local support groups, respite care and more.

Governmental resources

The National Institute on Aging has many articles and tools for caregivers and an up-to-date list of research studies that need volunteers — patients and caregivers alike.

And the Eldercare Locator from the U.S. Administration on Aging offers an online tool for finding resources in your area and an online chat feature to reach an experienced staff member during weekdays.

Beyond dementia

The Family Caregiver Alliance offers information, events and more for people who take care of any adult with serious physical or cognitive limits. It makes it easier to find information about programs in each state.

The Caring.com site acts as a clearinghouse of information for caregivers and families seeking care options for loved ones, for all kinds of conditions. Its database of care facilities powers AARP's care locator.
