WASHINGTON (AP) -- Your medicine really could work better if your doctor talks it up before handing over the prescription.

Research is showing the power of expectations, that they have physical -- not just psychological -- effects on your health. Scientists can measure the resulting changes in the brain, from the release of natural painkilling chemicals to alterations in how neurons fire.

Among the most provocative findings: New research suggests that once Alzheimer's disease robs someone of the ability to expect that a proven painkiller will help them, it doesn't work nearly as well.

It's a new spin on the so-called placebo effect -- and it begs the question of how to harness this power and thus enhance treatment benefits for patients.

"Your expectations can have profound impacts on your brain and your health,'' says Columbia University neuroscientist Tor Wager.

"There is not a single placebo effect, but many placebo effects,'' that differ by illness, adds Dr. Fabrizio Benedetti of Italy's University of Torino Medical School, who is studying those effects in patients with Alzheimer's, Parkinson's disease and pain.

The placebo effect is infamous from studies of new medications: Scientists often given either an experimental drug or a dummy pill to patients and see how they fare. Frequently, those taking the fake feel better, too, for a while, making it more difficult to tease out the medication's true effects. Doctors have long thought the placebo effect was psychological.

Now scientists are amassing the first direct evidence that the placebo effect actually is physical, and that expecting benefit can trigger the same neurological pathways of healing as real medication does. Among them:

--University of Michigan scientists injected the jaws of healthy young men with salt water to cause painful pressure, while PET scans measured the impact in their brains. During one scan, the men were told they were getting a pain reliever, actually a placebo.

Their brains immediately released more endorphins -- chemicals that act as natural painkillers by blocking the transmission of pain signals between nerve cells -- and the men felt better. To return to pre-placebo pain levels, scientists had to increase the salt-water pressure.

"Our brain really is on drugs when we get a placebo,'' says co-researcher Christian Stohler, now at the University of Maryland. More remarkable, some especially strong placebo responders suggest "many brains can actually stimulate that (pain-relief) system more.''

Italy's Benedetti gave Parkinson's patients a placebo and measured the electrical activity of individual nerve cells in a movement-controlling part of the brain. Those neurons quieted down, a decrease in firing of about 40 percent that correlated with a reduction in patients' muscle rigidity -- they moved more easily.

To further prove the power of belief, Benedetti hooked pain patients to a computerized morphine injection system. Sometimes the computer administered a dose without them knowing it; sometimes a nurse pretended to give it. The morphine was up to 50 percent more effective when patients knew it was coming.

Likewise, Parkinson's patients moved much better when they were told that doctors had turned on a pacemaker-like implant in their brains, which blocks tremors, than when it was turned on covertly.

But in a similar experiment with Alzheimer's patients suffering pain, Benedetti found no difference between covert or expected dosing. The results are preliminary, he cautioned a meeting of the Society for Neuroscience last month. But it appears that because Alzheimer's robs patients of the cognitive ability to expect a benefit, they need higher doses of painkillers to get as much relief as non-demented patients.

Placebos aren't a substitute for real medicine. But the research suggests maybe doctors should try to manipulate patients' treatment expectations, for at least some hard-to-treat conditions.

"The bigger question is how do we capitalize on the placebo effect,'' said Dr. Helen Mayberg of Emory University, whose studies suggest some antidepressants have a "placebo-plus'' activity in the brain. "There may be a phenomenon we all have access to.''


National Academy of Sciences Calls Current Ceiling Unsafe; Monitoring Your Local Supply

By SHARON BEGLEY Wall Street Journal March 23, 2006; Page D1

A panel of the National Academy of Sciences concluded yesterday that the maximum amount of fluoride currently allowed in the nation's drinking water can cause health problems and "should be lowered."

The report concluded that children exposed to four milligrams of fluoride per liter, the highest allowable level, risk developing severe dental fluorosis, in which teeth become mottled, pitted and scarred. Because fluoride can weaken bones, people who consume water containing that much fluoride over a lifetime are likely to be at increased risk for bone fractures.

Only 200,000 people in the U.S. live in places where water has fluoride levels of at least 4 mg. But an additional 1.4 million live where the concentration is at least half that, a level that can produce mild to moderate dental fluorosis. Most are in South Carolina, but there are thousands in Texas, Oklahoma and Virginia as well.

Fluoride levels as high as 4 mg are caused by natural rock and soil formations, not by the addition of fluoride to water. The government's recommended level for fluoride deliberately added to prevent cavities is only 0.7 to 1.2 milligrams per liter.

Still, the report will likely fuel debate in communities considering whether to add fluoride to their water. While it didn't address the 60-year controversy over whether it is safe to add fluoride to drinking water to prevent tooth decay, it is the latest development in a number of recent findings that have changed the thinking about fluoride.

Fluoride in moderation is known to strengthen teeth, but views have changed on how best to get it. While scientists used to believe that the benefits occurred mostly when people ingested fluoride so it circulated in their blood, a spate of new studies suggests that topical exposure (through toothpaste, gels and fluoride applications at a dentist's office) is equally important, if not more so. Overall, drinking fluoridated water cuts the rate of tooth decay 18% to 40%, according to a 2001 analysis by the U.S. Centers for Disease Control and Prevention -- which translates into fewer than one decayed tooth surface per person.

Consumers can learn how much fluoride is in their tap water by asking their local utility. Those with high fluoride levels can reduce fluoride exposure by using home water-filtration systems, which vary in their ability to remove fluoride from 13% to 99%, the committee found. So-called reverse-osmosis systems are the most effective at removing fluoride.

Worries about fluoride could increase demand for bottled water. That can have fluoride, too, but the limits for naturally occurring fluoride are lower. About 20 bottled-water makers add fluoride to some of their brands, including those in home and office coolers. Federal law limits fluoride in bottled water to 1.4 to 2.4 mg per liter if none is added by the bottler (as when the water comes from an already fluoridated source), and to 0.8 to 1.7 mg per liter if fluoride is added at the bottling plant. The range reflects the climate where the water is sold, with lower allowable levels in hotter regions. The label doesn't have to indicate fluoride content if the bottler doesn't add it.

There is no way, short of taking a bone sample, to unequivocally determine one's cumulative exposure to fluoride. It isn't possible to remove fluoride from the body as can be done for lead and other heavy metals. But "if you stop exposure, it will very gradually come out of the bone," committee member Thomas Webster of Boston University said.

While the panel called for the fluoride safety limit to be lowered, it is likely to take years before that might happen. For now, the panel's recommendation is that the Environmental Protection Agency, which requested and paid for the study, conduct a new risk assessment to determine how much lower the maximum fluoride level should be. If such a risk assessment agrees with the academy panel that four mg per liter is too high, the EPA could then use enforcement provisions of the Safe Drinking Water Act to compel water utilities to reduce fluoride levels.

A separate study to be published next week concludes that fluoride raises the risk of osteosarcoma, a rare bone cancer, especially in boys. Among boys drinking water with 30% to 99% of the 1 mg per liter fluoride level recommended for preventing cavities, the risk of osteosarcoma was estimated to be five times as great as among boys drinking nonfluoridated water. At one mg per liter or more, the risk was an estimated seven times as high. But because only 400 or so cases of osteosarcoma are diagnosed annually in the U.S., the absolute risk of the disease remains very low.

Other studies have shown no link between fluoridation and cancer. The national science panel called the evidence for osteosarcoma "tentative and mixed," because the studies as a whole do "not clearly indicate that fluoride either is or is not carcinogenic in humans." But because the hypothesis is biologically plausible -- fluoride is known to accumulate in bone tissue and causes bone cells to proliferate, and animal data suggest it is carcinogenic -- the committee concludes that "fluoride appears to have the potential to initiate or promote cancers, particularly of the bone."

The thoroughness of the report impressed even advocates of fluoridation. "It's an excellent piece of research," says John Stamm of the University of North Carolina School of Dentistry, a spokesman for the American Dental Association. "A number of jurisdictions have been waiting for this report." But Dr. Stamm said fluoride should be used "for reducing tooth decay," and its "accumulated safety and benefits level is quite remarkable."

In a surprise to even some longtime fluoridation opponents, the committee expressed concern about the effect of fluoride on IQ, noting that the "consistency of study results appears significant enough to warrant additional research" on the question. IQ deficits, the committee noted, have been strongly associated with dental fluorosis, in which teeth become scarred and weakened and develop yellow and brown mottling during the years teeth are forming. But the existing data are "not adequate" to say for sure whether fluoride can impair IQ.

One immediate effect of the report will be felt in communities that are weighing fluoridation. As of 2000, 162 million Americans have artificially fluoridated water. In recent years, local decisions on fluoridation have broken roughly 50-50. Antifluoridation advocates see the report as their strongest weapon ever.

"When one couples the risks with the lack of understanding on what the safe doses are for neurotoxic and other effects, it should cause a great deal of concern," says Michael Connett of the Fluoride Action Network, a nonprofit group that opposes fluoridation.

"Japanese scientists have identified a form of vitamin B12 that protects against neurological disease and aging by a unique mechanism that differs from current therapies.

Some of the disorders that may be preventable or treatable with this natural vitamin therapy, called methylcobalamin, include chronic fatigue syndrome, Parkinson's disease, peripheral neuropathies, Alzheimer's disease, muscular dystrophy and neurological aging.

Americans have immediate access to this unique and new form of vitamin B12, and, unlike prescription drugs, it costs very little and is free of side effects." Continue reading...
