Support & Insight for the Autumn of Life

It’s Not Alzheimer’s. It’s Just MCI.

Twenty percent of people over 65 have mild memory and thinking problems that don't interfere with day-to-day life. Doctors call this MCI, short for Mild Cognitive Impairment. Find out more about what it is and what to do about it.

For one in five Americans over age 65, getting older brings memory and thinking problems. It an also bring worry & embarrassment of not being as “sharp” as they once were. Learn why doctors call those first signs of trouble, Mild Cognitive Impairment, or MCI.

What can be done to prevent or slow MCI? And how much should seniors fear that their thinking or memory problems will get much worse? A pair of doctors from the University of Michigan Medical School and VA Ann Arbor Healthcare System have put together a definitive look at the evidence, based on a thorough review of recent studies about MCI.

Published in the Journal of the American Medical Association, their review article should help doctors and the seniors they treat.

“MCI is hard for both clinicians and for patients and their families, because it’s a scary prospect — and because there’s still a lot we don’t know about this condition,” says Kenneth Langa, M.D., Ph.D., who co-authored the article with U-M and VA colleague Deborah Levine, M.D., MPH. “We still don’t have great answers to give patients and families, but the medical literature shows there are certainly factors that can influence the risk, severity, and progression of MCI. We hope this review will spread awareness of those, and help guide patient care.”

“While no medications have been proven to treat MCI successfully,” says Levine, “it’s still a treatable condition. Our review shows good evidence that:

  1. Aerobic exercise
  2. Mental activity
  3. Social engagement
  4. Stroke prevention

help reduce the risk of further cognitive decline.” She notes that the review of medical literature they conducted paid close attention to the quality of the evidence in each study.

Among the key findings of their review, and what they mean for seniors:

Speak up to your doctor about memory and thinking problems: The new paper offers doctors a step-by-step guide for what to do when a patient or his or her caregiver mentions concerns about memory and thinking problems. Specific lab tests for things like vitamin deficiencies, standard cognitive tests and a full physical and neurological exam can reveal important clues to factors that might be causing their symptoms.

Keep body and brain active: A number of studies have indicated that aerobic exercise and mental activities can have a small beneficial effect on thinking ability in older adults with MCI.

Keep strokes at bay: Since strokes are brain injuries caused by clots or holes in the blood vessels that keep brain tissue healthy, it makes sense that preventing a stroke can preserve memory and thinking ability. People who have had mini-strokes or survived a full-blown stroke should especially focus on preventing new strokes to keep their brain function as intact as possible as they age, Langa and Levine advise based on the evidence they reviewed. So should people diagnosed with MCI. Having a stroke can worsen cognition and raises the risk of progressing on to dementia. Stroke prevention strategies include:

  1. Controlling high blood pressure
  2. Stopping smoking
  3. Lowering cholesterol with drugs called statins
  4. Taking aspirin or other medicines to prevent blood clots.

• Polypharmacology (Multiple medicines can fog the brain): Many seniors have prescriptions for a number of medications, and take over-the-counter drugs and supplements, to address their various health risks and conditions. These may have been prescribed or recommended by different doctors — who don’t always know or ask what else a patient is taking. But, say Langa and Levine, studies show that multiple drugs can interact with one another and affect memory and thinking. Doctors and seniors should review all drugs and supplements and see if any interactions can be prevented by reducing the number of medications the patient takes, or stopping drugs that aren’t needed after a hospital stay.

Avoid over-treatment of high blood pressure and diabetes: While it is important to control blood pressure and diabetes to prevent harmful consequences, doctors need to be careful not to overdo it. “It is important to avoid overtreatment of high blood pressure and diabetes because low blood pressure and low blood sugar may increase the risk of cognitive decline and other patient harms,” says Langa.

What are the odds?

That’s the key question in the mind of anyone with suspected or diagnosed MCI — how likely are they to get worse and progress to dementia and not be able to function independently. Reassuringly, Levine says, the evidence available shows that progression from MCI is far from a sure thing.

“The numbers are less scary than many people believe,” she notes. “The majority of people with MCI will not progress to dementia and loss of independence, even after 10 years. Some patients with MCI will actually have improved cognition after a year or two, if their cognitive test scores were brought down by an acute illness that gets addressed.” Older adults with MCI are 12 times more likely to die from cardiovascular disease than to die of dementia. So, preventing stroke and heart attack by controlling vascular risk factors is crucial for people diagnosed with MCI.

More evidence is needed for a number of new detection/treatment options. The review of the literature showed that a number of new blood tests and brain imaging options have been proposed and preliminarily tested for diagnosing MCI, and tracking or predicting its progression to dementia. But many of these tests haven’t yet been proven to offer significant benefit to patients, says Langa. And in fact, there can be some risk of “over-diagnosis” when a test identifies a problem that would not go on to cause significant problems for a patient.

In the end, he says, MCI can be a complicated issue, and that can make it even scarier for patients and their families. More research is needed on the factors that put someone at increased risk of MCI, new options for treating it, and better research on what the risk of progression to dementia is. But until new findings are available, this new review should help doctors and patients alike.

Very encouraging article! I was DX'd with MCI October 2014 & PET scan showed deterioration of HyppoCampus cells. I became fearful & stressed of developing demintia, was seen regularly by psychiatrist & counselor and off the 3 meds offered me only one (Aricept) did not have serious side-effects such as nightly horrible nightmares, etc… so I am now on Aricept only. After months of being reminded of my DX by psychiatric/counseling, I made a conscious decision while lying on my bed mentally numb by worry one afternoon a month ago that I was quitting all relations with psychiatry & sharing with my GP of my decisiion and as it turned out, regular visits to psychiatrists & her counselors were always putting the concern for progressing toward dementia in my mind… so I quit special treatment(except for Aricept now prescribed by my GP) & am free from worry & constant thinking about dementia. I have been genrally following advice in the above article… feel great… happy… peaceful… content. Still have irritability problems & lack of patience occassionally… but free from fear.

The article does not include information about non-drug treatment methods that have been shown to be effective in improving cognitive functioning in people with dementia. We are studying those methods and see great promise in them for both changing the slope of decline as well as helping to heal and prevent future damage to neurons and enhancing cortical connectivity.

Very good article. I myself have been diagnosed with MCI and have done a lot of research. I have identified many things I could do and started practicing / implementing them. I have developed a blog website, where I am sharing my findings and personal experiences. If anybody is concerned about MCI, he/she might be interested in checking it out.

Sorry to say,but you don't address the patients who are diagnosed @ a much younger age with MCI. In 2005, @ age 47, I was diagnosed with EOAD, then it was changed to MCI.
