DENVER, Colo. -- Brain Matters is a company that's made quite an impression on the Denver market. Turn on the TV, open the newspaper and there's the ad.

The company promises to give people a unique look at their brain that includes a detailed report addressing a multitude of medical problems. The company claims it can detect things like chronic fatigue, headaches, emotional changes, and Alzheimer's disease.

The last claim caught Paul Ketcham's attention.

"I've had some short-term memory problems over the last couple of years and I was reading the paper and saw the ad for this place. And I said I might as well try it because I've got to figure out what was going on," said Ketcham.

After contacting the clinic, Ketcham met with medical director Dr. Pamela Levine. She is not his primary care physician. In fact, Ketcham said his primary care physician was a bit skeptical of the test. Ketcham, however, proceeded with the test.

"He does have diabetes, high blood pressure. He's had heart disease, high cholesterol, and these are all risks for vascular dementia," said Levine.

The only way to know for sure, Levine said, was through a brain scan.

Ketcham first received an injection of a radioactive isotope. The liquid sticks to a patient's brain in areas where there is high blood flow. In areas where there is low blood flow, the results will appear dimmer in the scan. Low blood flow areas in some parts of the brain would indicate dementia.

In total, the machine took 128 pictures. The photos are a 360-degree, 3-dimensional snapshot of the brain.

Patients typically wait two to three weeks for the results. The outcome of the scan was a mixed bag for Ketcham.

"You don't have Alzheimer's, according to our test. You do have some kind of low blood flow that is indicative of some kind of dementia," said Nancy Goodhue, clinical director of Denver's Brain Matters.

Goodhue told Ketcham he will need to take the results to his primary care physician and begin a treatment plan to delay dementia. There are drugs on the market, she said, that can slow down the dementia but so far nothing that can reverse it.

"It's good news and bad news," said Ketcham.

"It concerns me because it is not going to be, at this point, reversible. So it's something I have to deal with and treat. I'm glad I'm doing it and I'm glad I took the test and this is what I wanted," said Ketcham.

Ketcham, like many of those 7NEWS has profiled in this series, said the optional test was worth it. The exam caught a problem, that until now, had gone undiagnosed. Now Ketcham can begin a treatment plan.

So we wondered, "Would Ketcham recommend the test to others?"

"If other people have the same type of symptoms that I felt I did, absolutely. Again, I think it's something that you need to know. Whether you can do a lot about it ... we'll find out," said Ketcham.
