Comparative studies on benefit are missing / Data on diagnostic and prognostic accuracy lack informative value The patient-relevant benefit of positron emission tomography (PET) in oesophageal cancer, alone or in combination with computed tomography (CT), is not proven due to a lack of comparative studies. In terms of their diagnostic and prognostic accuracy, it also remains unclear whether these diagnostic techniques can detect the spreading of tumors better than conventional diagnostics....

Survey suggests guidance and counseling need to be in place A leading group of Alzheimer's researchers contends that, as biomarkers to detect signals of the disease improve at providing clinically meaningful information, researchers will need guidance on how to constructively disclose test results and track how disclosure impacts both patients and the data collected in research studies. A survey conducted by a group including experts from the Perelman School of Medicine at the University...

Jet Pilots High Altitude Brain Lesions

Lee Rannals for redOrbit.com - Your Universe Online A study published in the journal Neurology found that high altitudes may increase the risk of brain lesions. Researchers reported that pilots who fly at high altitudes for extended periods of time are more likely to have brain lesions than non-pilots. The team performed MRI brain scans on 102 U-2 United States Air Force pilots and 91 non-pilots between the ages of 26 and 50. During the scans, the scientists measured the amount of white...

For the first time, researchers have documented irregular brain activity within the first 24 hours of a concussive injury, as well as an increased level of brain activity weeks later—suggesting that the brain may compensate for the injury during the recovery time. The findings are published in the September issue of the Journal of the International Neuropsychological Society. Thomas Hammeke, PhD, professor of psychiatry and behavioral medicine at the Medical College of Wisconsin, is...

Computer Model Reads Thoughts
2013-08-19 13:03:45

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal Neuroimage say they have developed a computer model that can read human thoughts. The scientists from Radbound University Nijmegen in the Netherlands reported that they have successfully created a mathematical model that can analyze MRI images to reconstruct thoughts and decipher letters that test subjects thought about. The team was able to teach a computer model how to analyze MRI images during...

Left Vs. Right: University Says Neither When It Comes To Brain Dominance
2013-08-19 11:11:25

Brett Smith for redOrbit.com - Your Universe Online The idea of a “left-brain” versus a “right-brain” personality has been used in a variety of contexts over the years, from interpersonal relationships to career choices. However, a new study from the University of Utah found that the idea of a dominant side of the brain affecting personality could be nonsense. Using brain imaging scans taken from over 1,000 volunteers, the Utah neuroscientists found that each side of the brain...

Famous Faces Test Can Help Spot Early Dementia
2013-08-13 05:03:14

redOrbit Staff & Wire Reports - Your Universe Online Simple tests that measure the ability to recognize and name famous people may help doctors identify early dementia in people 40 to 65 years of age, Northwestern University researchers reported Tuesday in the journal Neurology. "These tests also differentiate between recognizing a face and actually naming it, which can help identify the specific type of cognitive impairment a person has," said lead author Tamar Gefen, a doctoral...
