Common blood pressure drugs may slow dementia decline

Common blood pressure drugs may slow dementia decline

A class of drug used to lower blood pressure could potentially slow the rate of cognitive decline in dementia and even boost brain power, according to a study published by BMJ Open.

Researchers from Ireland analyzed the cognitive decline and brain power of 361 patients with an average age of 77. All had been diagnosed with either Alzheimer's disease, vascular dementia, or a mixture of both.

Of these patients, 85 were already using the blood pressure-lowering (antihypertensive) drugs known as ACE inhibitors (angiotensin-converting enzyme inhibitors). This is a commonly used class of antihypertensive drug. Thirty of the patients who were newly prescribed ACE inhibitors during the first six months of treatment were also analyzed for their brain power activity.

Between the years 1999 and 2010, the researchers used the Standardized Mini Mental State Examination (SMMSE) or the Quick Mild Cognitive Impairment (Qmci) to test the cognitive decline of each patient. This was done on two separate occasions, six months apart.

The patients who were taking ACE inhibitors had slower rates of cognitive decline in the study compared with patients who were not taking the drugs.

The study also revealed that in patients who had been newly prescribed the ACE inhibitors over the six-month period, their brain power improved in comparison with both those already taking them and those not taking them at all.

However, the study authors add that this could be due to the newly prescribed patients having better control over their medication regimen, or due to better blood pressure control or improved blood flow to the brain.

The researchers say:

"This [study] supports the growing body of evidence for the use of ACE inhibitors and other [blood pressure-lowering] agents in the management of dementia.

Although the differences were small and of uncertain clinical significance, if sustained over years, the compounding effects may well have significant clinical benefits."

The researchers warn, however, that previous research has indicated that ACE inhibitors may be harmful in some cases, so if future benefit of the drugs in dementia is proven, it may be limited to certain groups of patient.

The study authors call for further research and a controlled trial to confirm their findings. They say:

"If these data can be reproduced in a randomized trial of sufficient length, incorporating appropriate outcome measures, such as an amyloid positron emission tomography (PET), then these agents are likely to have significant benefits in delaying or even preventing dementia."

Should cancer screening be stopped as dementia progresses?

Should cancer screening be stopped as dementia progresses?

Research from the Regenstrief Institute and the Indiana University Center for Aging Research has found that many family caregivers of older adults with dementia are willing to consider stopping cancer screening of the elderly individual; they are also relieved when the older adult's physician brings it up.

"This openness of dementia caregivers to considering cancer screening cessation for older adults provides potential to reduce both patient burden and health care costs as well as family caregiver distress, while improving the overall quality of care for patients with dementia," said Regenstrief Institute investigator Alexia Torke, M.D., an IU Center for Aging Research scientist and an associate professor of medicine at the IU School of Medicine, who led the study. She points to other research showing that patients with serious illness such as dementia often receive cancer screening tests such as colonoscopy and mammography that may be burdensome to the patient but unlikely to be beneficial.

The researchers conducted focus groups with caregivers - from urban and suburban settings in one Midwest metropolitan area and of differing socio-economic status - attending support meetings for family members of dementia patients. The investigators found that caregivers' concerns about cancer screening for older adults with dementia targeted four areas:

Quality versus quantity of life. Burdens placed on the patient and caregiver by the screening. How to end screening. Variability of physician expertise on the risks and benefits of screening for this population.

"As dementia progresses, caregivers must take over the process of medical decision-making," Dr. Torke said. "Prior to our study, little had been known about how decisions to continue or stop screening are actually made by caregivers of family members with dementia, or if caregivers' perspectives on cancer screening were as positive as previous studies have found in other populations, including older adults."

For example, the perspective of the caregivers, who mostly favored forgoing cancer screening for older adults with dementia, differs from the perspective of older adults without cognitive impairment. A previous study conducted by the authors of this study found that adults who were not cognitively impaired viewed cancer screening as an automatic, recommended or obligatory action.

The researchers report in this new study that caregivers of people with dementia are not only willing to consider stopping cancer screening, many are relieved when physicians bring it up. Caregivers are most open to discussions of screening cessation when these discussions focus on quality of life and burdens and benefits for the person with dementia.

One caregiver said, "I was concerned about her quality of life and making sure that she was very, very comfortable, and I think that means more than putting people through a lot of unnecessary, uncomfortable ... procedures. ... It's not going to make the person better. It might make them linger on, but are you really living?"

The caregiver of another older adult said specifically of colon cancer screening, "At the point where my mother is right now, there's no way in the world I could get her to drink all that stuff and not eat. I'm thinking who's going to monitor all 24 hours a day? I can't do it. I can't do it. It's utterly impossible. So I can't send her through that and I can't go through it."

The caregivers, men and women ranging in age from 49 to 85, were primarily spouses or children of older adults with dementia.

The study "Caregiver perspectives on cancer screening for persons with dementia: Why put them through it?" appears July 19 online in advance of publication in the Journal of the American Geriatrics Society.

In addition to Dr. Torke, who is also a faculty member of the Fairbanks Center for Medical Ethics of IU Health, co-authors of the study are Peter H. Schwartz, M.D., Ph.D., of the IU School of Medicine and IU Center for Bioethics; Laura R. Holtz, B.S., and Kianna Montz, M.A., of the Regenstrief Institute and the IU Center for Aging Research; and Greg A. Sachs, M.D., of the Regenstrief Institute, IU School of Medicine and IU Center for Aging Research.
