A new survey offers further evidence of the substantial impact, financial and otherwise, that caregiving can have on family members who look after a relative with Alzheimer’s disease.

The online survey — conducted by the senior-care firm Caring.com — found that caregivers were likely to spend more than $50,000 a year on expenses related to their duties.

The survey, which was released at Wednesday’s US Against Alzheimer’s/Women Against Alzheimer’s “Out of the Shadows” Summit, also found that people who were taking care of someone with Alzheimer’s or another form of dementia were more likely to feel a negative impact at work because of their dual roles.

The survey of 2,098 U.S. adults was conducted online from July 8 to Aug. 10, 2015 and sampled people who searched online for assistance in caring for older adults.

More than 60 percent of those who responded also reported that their relative had Alzheimer’s or another form of dementia.

The survey found that people taking care of a relative with Alzheimer’s or another form of dementia were 20 percent more likely to say their duties conflicted with work (75 percent compared with 63 percent for other caregivers). They were also more likely to assist with paying bills, managing medications, providing daily care, such as dressing or feeding their loved ones. The survey also found that 42 percent of Alzheimer’s caregivers said they spent more than 30 hours a week on these tasks, compared with 30 percent of general caregivers who reported devoting the same amount of time to such duties.
