Magnetoencephalography: A Breakthrough Imaging Technique for Pediatrics
Magnetoencephalography (MEG) is an imaging technique that is currently being used before resective surgery in pediatric epilepsy patients to determine whether or not surgery is necessary and if the surgery will be successful. Before this technique was implemented, doctors had to rely on symptoms caused by seizures and traditional techniques that did not provide sufficient information about the success or possible long-term, adverse effects of resective surgery.
New MRI Opens New Doors
Magnetic Resonance Imaging (MRI) is an important imaging technique used in the medical field to diagnose many diseases and detect abnormalities in the human body non-invasively. In the neurological sense, an MRI is often performed to obtain an inner image of the brain if unusual activity is suspected. For example in the case of multiple sclerosis (MS), abnormal spots called lesions can be detected with an MRI before clinical symptoms occur.
Eat Less, Live Longer: By Diet or Drugs
For years, studies have shown that an almost foolproof way to live longer is to cut back on calories. In mice, cutting calories has not only extended their lifespan, but also their reproductive period. It is hypothesized that a low calorie diet in humans can have a similar effect.In yeast, it was demonstrated that decreasing caloric intake of these cells decreases SIR2, an inhibitor of an anti-aging enzyme. Lower production of SIR2 meant the longevity system of the cell flourished. We humans have similar genes, and it is likely it is modulated in a similar manner.
Diabetes Protects Against Migraines
Researchers are grappling with findings that people living with diabetes are less likely to have migraines, and vice versa. While the data has been made public about populations in several regions for quite some time now, for the first time a series of systematic studies and reviews conclude that these findings are not just a fluke. An entire region in Norway was sent a questionnaire. The 1,499 people who self reported to be living with any form of diabetes were found to have a significantly lower rate of migraines than those reporting to be non-diabetics.
