The test in question is the electroencephalogram or brain-wave test, and for certain medical conditions it is the key to accurate diagnosis. Medical Tests: What Does a "Normal Range" Mean?  By : Gary Cordingley, MD, PhD What is the difference between a laboratory test-result that is "normal" and one that is "unremarkable?" The answer, it turns out, lies at the intersection of statistics and clinical meaning. The Neurological Exam: Evaluating the Master Organ  By : Gary Cordingley, MD, PhD It might seem old-fashioned, but the neurological physical exam is still the best starting-point for investigating symptoms related to the brain and other parts of the nervous system. CT and MRI Scans in Neurological Practice: A Quick Overview  By : Gary Cordingley, MD, PhD Have you ever wondered how computed tomographic (CT) and magnetic resonance imaging (MRI) scans are made? Admittedly, some of it occurs by magic, but the truth can be told about the rest of the process. Lumbar Puncture: This (Really) Is Spinal Tap  By : Gary Cordingley, MD, PhD While devised over a century ago, the medical test known as lumbar puncture is still the gold-standard procedure for diagnosing a number of serious conditions affecting the brain and spinal cord.

Read on... Nerve Conduction Studies: What Are They?  By : Gary Cordingley, MD, PhD Pinched, damaged or under-functioning nerves can produce numbness, weakness or pain. If such a condition is suspected, your doctor might refer you for specialized testing called nerve conduction studies. New Gene Tool May Unlock Root Causes of Disease  By : Rita Jenkins. Genetic researchers have made substantial advances in understanding the root causes of common diseases and the history of human evolution. An international consortium of more than 200 scientists has concluded that genetic variants located physically close to each other are inherited collectively as groups, called haplotypes. The comprehensive catalog of all of these blocks is known as the "HapMap." Aspartame Causes Cancer in Rats  By : Rita Jenkins. Rats given varying doses of aspartame -- the second most widely used artificial sweetener in the world -- experienced a statistically significant increase in the incidence of malignant tumors, lymphomas and leukemias in a recent study. The effects were observed at a daily dose of 20 milligrams per kilogram (mg/kg) of body weight -- which is less than the current acceptable daily intake for humans. NaProTechnology: A Medical Breakthrough in Infertility Treatment  By : David Picella In New Hope For Infertility With NaProTechnology, the advantages of a new reproductive science that uses the physician’s medical and surgical energies in a way that works cooperatively with a woman’s natural reproductive function is reviewed. Current artificial reproductive technologies (ART) in widespread use rely on unnatural laboratory procedures rather than natural sex and are associated with significant risks and moral objections.

Omega 3 fish oil - The Evidence  By : David McEvoy The evidence suggesting that Omega 3 fatty acids prevent heart disease is of several scientific types: epidemiological evidence and archeological evidence support the claim, as well as evidence from animal studies, observation studies, and interventional studies. Feeling Fat (or Thin) May Be a Trick of the Mind  By : Rita Jenkins. Whether you feel fat, thin or something in between has little to do with the reality of the situation, suggests a new study. A person's self-image is an illusion constructed in the brain, the researchers say. The study results may shed some light on anorexia, an eating disorder, and body dysmorphic disorder, which may cause sufferers to worry over small or imagined defects, and to overestimate or underestimate their actual body size. Marital Clashes Can Slow Body's Healing Process  By : Aaron Potts Marital arguments can leave a husband and wife feeling emotionally wounded, but that's not all. Scientists have discovered that the stress of a typical 30-minute tiff can prevent physical wounds from healing by at least one day. Moreover, couples whose relationships are generally hostile may suffer longer delays in the healing process -- even twice as long. NaProTechnology In The Ovulation Toolbox  By : Paddy Jim Baggot .

Fortunately, there is a new reproductive science, called NaProTechnology that expands the physician's diagnostic and therapeutic capabilities for treating reproductive problems. In this article, the application of this new perspective in reproductive medicine is added to "The Ovulation Toolbox." Research Shows...Facts About ADHD  By : Angie Dixon There are a lot of theories about ADHD, and a few of them are actually based in fact. I recently ran across some information from the National Institutes of Mental Health that I found really interesting. Is It Really ADHD?  By : Angie Dixon "But ADHD symptoms are just things everyone does." Have you heard this? If you haven't, keep listening. I'm sure you will soon, probably from someone who means well. And it is true that not everyone who is overly hyperactive, inattentive or impulsive has ADHD. Pacifiers May Help Prevent Crib Death  By : Nicole Weaver The risk of Sudden Infant Death Syndrome, or SIDS, is dramatically lower among infants who are given pacifiers while they sleep, according to a new study. The protective effect of the pacifier seemed evident even for those infants who were in an adverse sleep environment, such as sleeping face down or on the side, sleeping with a mother who smoked, or sleeping on soft bedding, the researchers found. Dog Genome May Shed Light On Human Disease  By : Tom Harrison Scientists have succeeded in sequencing the dog genome, an accomplishment that could lead to better health for humans as well as canines.

Recent Studies Show How Our Bodies Fight Disease  By : Rick Hendershot **Obese people less likely to survive colorectal cancer According to a new report, people who are physically inactive and are obese around the middle have poor odds of survival after a diagnosis of colorectal cancer. "We have now shown that modifiable lifestyle factors that were known to reduce the incidence of colorectal cancer can also reduce the mortality in cases diagnosed with the disease," Dr. Andrew M. M. Haydon told Reuters Health. "This strengthens the argument... Diagnosing Crohn's Disease - How To Get A Diagnosis  By : Sarah K. Jenkins Diagnosing Crohn’s Disease is often a difficult process. Because it mimics other diseases, Crohn’s may appear to be a myriad of other ailments. Likewise, the symptoms experienced vary from patient to patient, so there are no set guidelines to follow or sings that intrinsically point to Crohn’s. There is not a single to test to establish the existence of Crohn’s Disease definitively. However, there are several procedures that are done to ascertain if Crohn’s, as well as oth...
