Your Symptoms Are Real: What to Do When Your Doctor Says Nothing Is Wrong Benjamin H. Natelson, M.D. See book keywords and concepts

To shed more light on how we carried out all this research, it's worth talking about how mri scans work. You've probably heard of these tests, which enable doctors to see the anatomy of everything under the skin, but few people are really aware of how they work. The most common application of MRI is to look for anatomical abnormalities. The scans work by imaging the amount of water in different bodily tissues, with bone having the least and spinal fluid or blood having the most.

Overtreated: Why Too Much Medicine Is Making Us Sicker and Poorer Shannon Brownlee See book keywords and concepts

In 2002, Blue Cross Blue Shield of Missouri calculated that 20 to 30 percent of their claims for PET, CT, and mri scans were for unnecessary tests. In states where malpractice laws make it less likely that doctors will be sued, there's only about a 15 percent difference in the amount of unnecessary treatment doctors deliver. This suggests that only a fraction of the useless scans being performed can be laid at the feet of defensive medicine. No study ever conducted has shown that malpractice worries or patient demand can account for any more than a tiny fraction of unnecessary care.

Spark: The Revolutionary New Science of Exercise and the Brain John J. Ratey, MD See book keywords and concepts

One recent study used mri scans on eight yoga practitioners and found that their levels of the neurotransmitter gamma-aminobutyric acid (GABA) increased 27 percent after a sixty-minute session. GABA is the target of Xanax-like drugs and is very involved with anxiety, so this may be part of the reason why yoga helps some people relax. Much of the evidence from this realm is anecdotal, but I'm sure that as neuro-scientists delve deeper into the brain they'll discover pathways that connect the dots.

Contrary to what scientists originally assumed, studies comparing mri scans of brain activity in adults with and without anxiety disorders show no difference in how the amygdala responds to a legitimately frightening stimulus (such as pictures of fear-stricken faces, which have a powerful effect because human beings are programmed to interpret facial expressions as survival cues). The difference is in how they respond to a nonthreatening stimulus.

Gray matter is the thin, wrinkly covering of the brain made up of cells that direct all of our complex functions such as attention, emotions, memory, and consciousness. The mri scans pointed toward a radical notion: that chronic depression may cause structural damage in the thinking brain. Related research showed that depressed patients also had measurable changes in the amygdala and the hippocampus, crucial players in the stress response. We knew the amygdala was central to our emotional life, but we were just discovering that the memory center was also involved in stress and depression.

The seminal 2006 study from Arthur Kramer of the University of Illinois used mri scans to show that walking as few as three days a week for six months increased the volume of the prefrontal cortex in older adults. And when he tested aspects of their executive function, they showed improvement: in working memory, smoothly switching between tasks and screening out irrelevant stimuli. Kramer wasn't on the trail of ADHD, but his findings illustrate another way exercise might help. Everyone agrees that exercise boosts levels of dopamine and norepinephrine.

In one study, older adults who reported having a strong history of aerobic exercise clearly had better preserved brains, according to mri scans. But a correlation is merely interesting to lab scientists. They wanted to see if exercise caused structural changes in these areas. A team led by neuroscientist Arthur Kramer divided fifty-nine sedentary people ranging in age from sixty to seventy-nine into two groups that would hit the gym three times a week for one hour over the course of six months.

Those who appeared to respond to the vaccine with cognitive improvement had a greater degree of shrinkage of the brain on mri scans. No one knows what caused this puzzling result. Perhaps because the amyloid was being cleared from the brain, the brain volume was reduced as a result. Whatever the case, this result was the opposite of what most people expected. The apparent clinical improvements were small and might have been due to chance, as in any study where there appears to be a subgroup of people who respond to a drug.

However, these details can at times be more confusing than helpful. mri scans can show smaller strokes, and that is helpful in the differential diagnosis of vascular dementia; but it also shows what we call "unidentified bright objects," which are of unclear significance and could indicate anything from small strokes, to normal aging, to other phenomena that we don't understand. PET (positron emission tomography) scanning shows the brain at work, i.e., a form of functional imaging.

But the groundbreaking finding came from mri scans before and after: those with improved fitness had an increase in brain volume in the frontal and temporal lobes. Scientists knew that this could happen in the hippocampus, but the suggestion that brain volume increased in the cortex was "out there," in the estimation of neuroscientist Carl Cotman, the researcher who pinpointed the link between exercise and BDNR "I'm sure he's right," Cotman says of Kramer. "He's a very honest, accurate guy. But the findings are definitely on the outer fringe.

Standard CT and mri scans are a part of routine practice, although there is some controversy about when to use each. However, advanced and expensive neuroimaging techniques have been promoted extensively over the last quarter-century, promising much, but delivering relatively little. Imaging is categorized into two approaches: structural and functional. MRI (magnetic resonance imaging) is a structural approach that provides more details than CT (computerized tomography) scanning, which is the most commonly used and cheapest form of structural imaging.

Men and women who ate tofu at least twice per week experienced accelerated brain aging, diminished cognitive ability and were more than twice as likely to be clinically diagnosed with Alzheimer's disease. mri scans showed enlarged ventricles while autopsies revealed atrophied brains with lower weights. Subjectively, the researchers couldn't help but notice that by age 75 to 80 the tofu eaters looked about five years older than those who abstained.4'-43 The industry claims "the tofu effect" is just a fluke but the statistical probability of the results being true varied from 95 to 99.

Doctors can perform spinal taps, testing the cerebrospinal fluid or do mri scans to look for abnormal antibodies and myelin damage, but because MS may cause damage much like that from a virus or other autoimmune disorders, the tests are often inclusive. In most cases, a diagnosis is made only when all other possibilities are ruled out. If you have MS or MS-like symptoms, it's critical that you find a good specialist and work closely with him or her. Despite the common perception, many people with MS live long, productive lives.

The Divided Mind: The Epidemic of Mindbody Disorders John E. Sarno, M.D. See book keywords and concepts

Because so few members of the medical profession recognize mindbody disorders for what they are, the pain of TMS is commonly attributed to a structural abnormality, such as the ones that often show up on x-rays, computed tomography (CT), or mri scans. Following is a list of the most common ones: Abnormalities of the intervertebral disc due to wear and tear, aging, etc.

Use of PET scans and/or functional mri scans may elucidate some of the specific brain changes in the pre- and post-treatment patient population. Noninvasive oxygen tensiometry can document improvements in muscle oxygenation in symptomatic regions pre- and post-treatment. However, the physiology of TMS is relatively unimportant. It is basically a psychological disorder with physical symptoms. Undoubtedly, the brain could create pain in a variety of ways, so focusing on the physiology is unnecessarily diverting from the important question: why does the brain-mind do it?

This is the same route they took with chronic fatigue syndrome, even though brain lesions were being seen on mri scans. I was convinced at the time that the tremendous increase in this disorder was in some way related to the large amounts of food excitotoxins being ingested. A recent clinical study by Dr. J. D. Smith and his co-workers found that complete or near-complete relief could be attained by removing all MSG- and aspartame-containing foods and FIGURE 7.

Kelly reviewed the scans then wrote to Paul's parents: "I have reviewed the mri scans on your five-year-old son Paul ... it is the largest tumor I have ever seen in this area in anybody ever referred to me for surgery. I showed your scans to a number of my colleagues here who feel that it is inoperable . . . .Without surgery, your boy will die."12 Because of the serious risks involved in attempting surgery or radiation, Paul's family elected not to pursue those treatments. By 1988, they finally found out about and started Paul on Burzynski's antineoplastons.

EEGs and mri scans of the brain can sometimes provide supporting evidence. The name of the disease, however, still confuses both the public and some in the media, who forget to add "variant" to CJD. Other names have been floated, including "Will-Ironsides syndrome" by the National Institutes of Health's Paul Brown , without success. To the Churchills, their son Stephen died of BSE. If you contracted anthrax naturally, from a wild animal, Dave said, "people would say you died of anthrax." There's no formal way to name diseases.

Diagnosis of the specific disease may include mri scans, CT scans, and biopsy. 3. Chemotherapy and radiation therapy are usually used in combination to treat these diseases. The actual course of therapy depends on the specific type of disease. 4- Interferon-alpha, a biologic response modifier, has been proven effective in the treatment of some leukemias and low-grade lymphomas. 5. Patients who do not respond to chemotherapy and radiation therapy may be considered for peripheral blood stem-cell transplants or bone marrow transplants. 6.

In conjunction with evaluation, X rays, blood tests, and mri scans are used if there is a suspicion of deeper pathology.7 Types of Therapy Used Different manipulative approaches are available to the osteopathic physician, including: Gentle mobilization: Moving a joint slowly through its range of motion, gradually increasing the motion to free the joint from restrictions. Articulation: When motion is severely limited, a quick thrust (similar to chiropractic) may be used.

We had been frightened that something abnormal would show up on the CT and mri scans that first night in the emergency room, but I was now almost hoping to see something on a brain scan that would help explain what being Floxed meant. Instead of a PET scan, Diane was given something similar, called a SPECT scan, which also assesses inconsistencies in the flow of blood through the brain. Her SPECT scan did show a mild abnormality. Interpreting it was something else; brain scientists are still trying to figure out exactly what they are seeing in these scans.

Schwartz, a professor of medicine at the Tufts University School of Medicine. mri scans cost $500-$ 1000 per hour examination (Waldhoz and Bogdanich, 1989.) Schwartz asks "at what point we can do more good by spending the money on, say, preventive medicine or the environment" (New York Times, May 15, 1988). So great has fear of cancer's economic cost become that a new industry has sprung into existence: cancer insurance.

MRI scans. Dr. Braverman challenges an individual's brain function through the use of various images and sounds, and a test that requires an individual to perform a variety of mental tasks. Meanwhile, the voltage output of the brain is measured with the aid of a standard EEG device. It is this measure that Dr. Braverman says provides a good indication of the level of brain function. • Brain nutrient decline, such as levels of amino acids (specifically trytophan and tyrosine), the B vitamin choline, and phosphatidyl-serine. • Altered blood flow to the brain.

Sonograms and mri scans may be helpful, but they are not definitive in making the diagnosis. Proper diagnosis is important, notes Dr. Anthony Aurigemma, because while endometriosis is considered benign, it can become malignant. CONVENTIONAL THERAPY Treatment usually consists of medical prescriptions for pain control and reduction of endometrial growth. Antiprostaglandin medicines, such as Indomethacin, Ibuprofen, and Naprosyn, are often given to reduce pain. Another popular pharmaceutical, Danazol, is also used for this purpose, but in some women it does not provide total or lasting relief.

In one study, mri scans were used to examine the spines of people with no back pain. Two thirds of them had spinal abnormalities, including herniated and degenerated disks. If these problems had been seen in someone with back pain, they probably would have led to surgery. The researchers suggested that it may be sheer coincidence when a person with back pain is found to have a disk abnormality and that physicians may do surgery simply because they have a bias toward doing something.

Karson's study using functional mri scans with Prozac accumulating in the brain at a rate 100 times greater than the blood and taking so long to wash out, any drug prescribed to the patient for quite a long period of time would be mixing with Prozac still in the body and possibly having its effects multiplied. This is incredibly significant in understanding why withdrawal is delayed, why such a long withdrawal, and why such strong reactions to other drugs are experienced after Prozac use. It should also change decisions in a number of court cases.
