Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

tDCS electric stimulation can improve motor function in stroke patients

A noninvasive electric stimulation technique administered to both sides of the brain can help stroke patients who have lost motor skills in their hands and arms, according to a new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC).

Simple test and an MRI predicts future Alzheimer’s disease

Until now is has been believed that Alzheimer’s disease and other forms of dementia could be diagnosed only when symptoms appear which almost always means when patients are in their 70s or 80s. Now the latest research shows that some brain lesions are characteristic of Alzheimer’s disease and can be detected in the brains of healthy people in their 40s. Along with this a simple mental skills test may be able to detect the problem many years sooner than previously thought.

Breast cancer patients more likely to have joint pain from taking AIs: Study

Breast cancer patients are more likely to have joint pain from taking aromatase inhibitors if they have advanced stage cancer, according to a study presented at the American College of Rheumatology's annual meeting, held Nov. 7-11, in Atlanta. The study is one of the first to identify factors that increase the likelihood that a patient will suffer joint pain from AI therapy.

SIMPONI injection improves inflammation, structural damage in RA patients

Magnetic resonance imaging (MRI) analyses from two Phase 3 clinical trials showed that once every four week subcutaneous injections of SIMPONI (golimumab) 50 mg plus methotrexate resulted in statistically significant improvements in markers of inflammation and structural damage in patients with active rheumatoid arthritis (RA) compared with placebo plus methotrexate.

'Phantom' images brain keeps for visual comparisons stored in brain's neural network

Brain research over the past 30 years has shown that if a part of the brain controlling movement or sensation or language is lost because of a stroke or injury, other parts of the brain can take over the lost function - often as well as the region that was lost.

Scientists discover gene variant that rewires brain's circuitry in neurological disorders

Many gene variants have been linked to autism, but how do these subtle changes alter the brain, and ultimately, behavior. Using a blend of brain imaging and genetic detective work, scientists at UCLA's David Geffen School of Medicine and Semel Institute for Neuroscience and Human Behavior are the first to illustrate how a gene variant tied to autism rewires the brain.

Study reveals a potential target for treating brain trauma

Brain damage continues to develop and evolve for months after a traumatic brain injury (TBI), revealing a potential target for treatments to improve brain trauma, new research led by the University of Melbourne, Australia has found.

Visual attention diminishes with age

A University of Toronto study shows that visual attention -- the brain's ability to selectively filter unattended or unwanted information from reaching awareness -- diminishes with age, leaving older adults less capable of filtering out distracting or irrelevant information.

Study finds DHA supplementation does not reduce risk of AD

Patients with mild to moderate Alzheimer's disease (AD) who received supplementation with the omega-3 fatty acid docosahexaenoic acid (DHA), believed to possibly reduce the risk of AD, did not experience a reduction in the rate of cognitive and functional decline, compared to patients who received placebo, according to a study in the November 3 issue of JAMA, a theme issue on aging.

Lactic acid levels in brain linked to aging process

Researchers at Karolinska Institutet have shown that they may be able to monitor the aging process in the brain, by using MRI technique to measure the brain lactic acid levels. Their findings suggest that the lactate levels increase in advance of other aging symptoms, and therefore could be used as an indicator of aging and age-related diseases of the CNS.

Molecular imaging technique pinpoints changes that take place in injured brain

Results from a study published in the November issue of The Journal of Nuclear Medicine (JNM) show that powerful imaging techniques positron emission tomography (PET) fused with magnetic resonance imaging (MRI) are helping researchers better understand the long-term functional and structural changes that take place after traumatic brain injury (TBI).

Brain MRI could predict duration of stroke onset

Magnetic resonance imaging (MRI) of the brain could expand the number of stroke patients eligible for a potentially life-saving treatment, according to a new study, published online and in the December issue of the journal Radiology.

Study finds breast MRI equipment in U.S. meets ACRIN and EUSOBI standards

An overwhelming majority of Breast Cancer Surveillance Consortium (BCSC) facilities performing breast magnetic resonance imaging (MRI) in the U.S. are up-to-par with American College of Radiology Imaging Network (ACRIN) and European Society of Breast Imaging (EUSOBI) technical standards and requirements, according to a study in the November issue of the Journal of the American College of Radiology.

More effective therapeutic exercises underutilized in treatment of chronic neck pain

Duke University and University of North Carolina (UNC) researchers report in the November issue of Arthritis Care & Research that narcotics and diagnostic testing are overused in treating chronic neck pain. Their findings indicate clinicians may overlook more effective treatments for neck pain, such as therapeutic exercise. According to reviews cited in the study, evidence to support the effectiveness of therapeutic exercise in treating chronic neck pain is good, yet only 53% of subjects were prescribed such exercise.

Study finds anti-obesity drug reduces brain’s response to appetizing foods

Scientists have revealed that an anti-obesity drug changes the way the brain responds to appetising, high-calorie foods in obese individuals. This insight may aid the development of new anti-obesity drugs which reduce the activity in the regions of the brain stimulated by the sight of tasty foods.
