Alzheimer's screenings often left out of seniors' wellness exams in US

Primary care doctors in US are really good at checking seniors' cholesterol levels and blood pressure but often fail to use tests that could detect dementia.

Fewer than half of primary care doctors surveyed said they routinely test patients 65 and older for problems with memory and thinking, according to a report released on Tuesday by the Alzheimer's Association, Headquartered in Chicago, Illinois, the US, www.npr.org reported.  

And just 16 percent of older patients surveyed said they receive regular cognitive assessments during routine health checkups, the report said.

In contrast, 91 percent of seniors said their annual visits include a blood pressure check, and 83 percent said they include a cholesterol test.

"This cognitive assessment should be part of every senior's annual wellness visit," said Keith Fargo, the director of scientific programs and outreach for the Alzheimer's Association.

"But we're seeing that it's simply not happening."

A cognitive assessment typically takes a few minutes and may include questioning the patient or the patient's family, observing the patient's interactions or using short verbal or written tests.

Yet because doctors often skip the evaluation, many seniors are diagnosed only when they are severely impaired, Fargo said.

As a result, it is often too late for the patient to plan for the future or enter a clinical trial.

"The first person who gets a drug that stops their Alzheimer's disease will get that drug in the context of a clinical trial," Fargo said.

"And that's only going to happen to someone who knows they have cognitive decline."

The report found that 82 percent of seniors think it's important to have their thinking and memory checked out regularly. And 94 percent of primary care physicians said it's important to assess every patient 65 and older for cognitive impairment.

Yet many doctors remain hesitant to broach the subject of cognitive testing with their older patients, said Joanne Pike, the chief program officer of the Alzheimer's Association.

"Usually what we're seeing is that physicians are waiting for the senior to bring any concerns to them," Pike said.

And seniors rarely do that, for a variety of reasons, Pike said.

"Some of it could be fear, some of it could be stigma and some of it could be a little bit of, unfortunately, people believe that there's not a benefit to knowing about the disease or dementia," Pike said.

One common fear among doctors is that they will harm an older patient by doing an assessment that reveals a cognitive problem, said Nicole Fowler, an assistant professor of medicine at Indiana University School of Medicine — the US — and a scientist with the Regenstrief Institute's — the US — Center for Aging Research.

So Fowler and a team of researchers did a study to see whether patients were harmed.

"And what we found actually in that study is that there wasn't any harm, so there was no increase in rates of depression or anxiety in older adults who were screened," she said.

Even so, it can be hard to get seniors who have a cognitive problem to see a specialist and get the right sort of care and counseling, Fowler said.

At least half the time, she said, patients refuse to act on the results of a cognitive assessment.

The solution is to have the medical system take a more active role in keeping in touch with people who've had a screening test.

"We would never send somebody for a mammogram and then never follow up with them," she said.

Some primary care doctors resist performing routine cognitive screening because studies haven't shown a clear benefit, said Dr. Sheryl Sun, chief of internal medicine at Kaiser Permanente in Santa Clara, California, the US.

The US Preventive Services Task Force, for example, says the current evidence on cognitive screening is insufficient to assess whether it does more harm or good.

So it is hard to justify spending valuable time during a patient's visit to do a cognitive assessment, Sun said.

"If you spend time doing things of questionable value, you might not get to the things that are of proven value," like screening for heart disease or diabetes, she said.

"Also, primary doctors who know their patients well don't need formal tests to detect cognitive problems," Sun said.

"We will notice a change within a few minutes of walking in the exam room."

Cognitive tests make sense when a doctor suspects a problem, Sun said.

But they probably won't become routine until researchers develop an effective treatment for Alzheimer's disease.
