Extremes of stroke symptoms attract misdiagnoses

Extremes of stroke symptoms attract misdiagnoses

Patients with very mild or very severe stroke symptoms are at the greatest risk of being misdiagnosed in the emergency department, research suggests. [More]
Researchers examine brain networks involved in PTSD and TBI

Researchers examine brain networks involved in PTSD and TBI

Posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) can have devastating consequences. Both are associated with high rates of disability and suicide, and although they are separate conditions, they commonly co-occur. For example, a soldier who has developed PTSD as a result of a traumatic experience may have also sustained a brain injury during that experience. [More]
Stanford researchers identify iron-containing microglia in the brains of people with Alzheimer's disease

Stanford researchers identify iron-containing microglia in the brains of people with Alzheimer's disease

Examining post-mortem tissue from the brains of people with Alzheimer's disease, Stanford University School of Medicine investigators identified what appear to be iron-containing microglia -- specialized scavenger cells that sometimes become inflammatory -- in a particular part of the hippocampus, a key brain structure whose integrity is critical to memory formation.

New approach to imaging glucose uptake activity in single living cells

New approach to imaging glucose uptake activity in single living cells

Researchers at Columbia University have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance. In a recent study published in Angewandte Chemie International Edition, Associate Professor of Chemistry Wei Min's team developed a new glucose analogue that can mimic the natural glucose, and imaged its uptake as energy source by living cancer cells, neurons and tissues at the single cell level.

Very small cerebrovascular lesions warrant concern

Very small cerebrovascular lesions warrant concern

Subclinical cerebrovascular smaller than 3 mm are associated with an increased risk of stroke and stroke mortality, report researchers. [More]
INSIGHTEC announces additional positive coverage policies for ExAblate MRgFUS procedure for bone metastases

INSIGHTEC announces additional positive coverage policies for ExAblate MRgFUS procedure for bone metastases

INSIGHTEC announced today that Blue Cross Blue Shield of Massachusetts, Blue Cross Blue Shield of Mississippi, Wellmark Blue Cross Blue Shield, Blue Cross of Idaho and Blue Cross Blue Shield of Arizona have published an updated coverage policy regarding INSIGHTEC's ExAblate MRgFUS (Magnetic Resonance Imaging-guided Focused Ultrasound) procedure which provides benefits for bone metastases patients. The ExAblate treatment is FDA-approved for patients suffering from pain associated with bone metastases. [More]
Gene therapy used for sight restoration also strengthens visual pathways in the brain

Gene therapy used for sight restoration also strengthens visual pathways in the brain

Since 2007, clinical trials using gene therapy have resulted in often-dramatic sight restoration for dozens of children and adults who were otherwise doomed to blindness. Now, researchers from the Perelman School of Medicine at the University of Pennsylvania and The Children's Hospital of Philadelphia, have found evidence that this sight restoration leads to strengthening of visual pathways in the brain, published this week in Science Translational Medicine.

New imaging technique could help with early detection of Alzheimer's disease

New imaging technique could help with early detection of Alzheimer's disease

Various types of information can be ascertained by the way blood flows through the brain. When a region of the brain has been activated, blood flow increases and oxygenation rises. By observing variations in blood flow with the help of non-invasive imaging, it is possible to determine which regions are at work at a given point in time and how they work together. [More]
Key parts of the human brain network give power to control, redirect attention

Key parts of the human brain network give power to control, redirect attention

Researchers at Columbia University Medical Center have found that key parts of the human brain network that give us the power to control and redirect our attention--a core cognitive ability--may be unique to humans. [More]
Studies using MRI techniques can reveal brain connectivity differences in people with ASD

Studies using MRI techniques can reveal brain connectivity differences in people with ASD

Studies using magnetic resonance imaging (MRI) techniques are beginning to reveal differences in brain connectivity--the ways that different parts of the brain are connected to each other and work together--in people with autism spectrum disorders (ASD), reports a review in the Harvard Review of Psychiatry.

Researchers examine limits of human hearing

Researchers examine limits of human hearing

Are wind farms harmful to humans? Some believe so, others refute this; this controversial topic makes emotions run high. To give the debate more objectivity, an international team of experts dealt with the fundamentals of hearing in the lower limit range of the audible frequency range (i.e. infrasound), but also in the upper limit range (i.e. ultrasound).

Neuroscientist receives $2.9 million grant to explore link between language and brain function

Neuroscientist receives $2.9 million grant to explore link between language and brain function

Can reading interventions positively impact reading skills and math skills? If so, can the improvement be observed inside the brains of children with combined reading and math disabilities? [More]
Study: Brain activity changes after memory retraining in TBI patients

Study: Brain activity changes after memory retraining in TBI patients

Kessler Foundation researchers published results of their TBI-MEM trial, the first study to demonstrate significant changes in cerebral activation after memory retraining in individuals with traumatic brain injury. [More]
Decreased connectivity between network-specific brain regions linked to cognitive deficit in MS

Decreased connectivity between network-specific brain regions linked to cognitive deficit in MS

An estimated 2.3 million individuals are living with multiple sclerosis (MS) worldwide. Approximately half of all individuals with MS experience changes in cognition such as impaired concentration, attention, memory, and judgment. The underlying brain basis for these deleterious effects has been largely elusive. [More]
Discovery reveals possibility of using water for finer analysis of the brain's functioning

Discovery reveals possibility of using water for finer analysis of the brain's functioning

To observe the brain in action, scientists and physicians use imaging techniques, among which functional magnetic resonance imaging (fMRI) is the best known. These techniques are not based on direct observations of electric impulses from activated neurons, but on one of their consequences. Indeed, this stimulation triggers physiological modifications in the activated cerebral region, changes that become visible by imaging. [More]
DGIST researchers set on creating microrobot-assisted procedure for dealing with blocked arteries

DGIST researchers set on creating microrobot-assisted procedure for dealing with blocked arteries

Swarms of microscopic, magnetic, robotic beads could be scrubbing in next to the world's top vascular surgeons--all taking aim at blocked arteries. [More]

Helen DeVos Children's Hospital uses two imaging techniques to produce hybrid 3D model of a patient's heart

Congenital heart experts from Spectrum Health Helen DeVos Children's Hospital have successfully integrated two common imaging techniques to produce a three-dimensional anatomic model of a patient's heart. [More]

MSD announces EC approval of SIMPONI (golimumab) for treatment of adult patients with nr-axial SpA

MSD (Merck & Co., Inc., Kenilworth, New Jersey, USA) today announced that on 22 June the European Commission approved SIMPONI (golimumab) for the treatment of adult patients with severe, active non-radiographic axial spondyloarthritis (nr-axial SpA). [More]
New UCLA study may lead to more precise treatments for obsessive-compulsive disorder

New UCLA study may lead to more precise treatments for obsessive-compulsive disorder

Tens of millions of Americans -- an estimated 1 to 2 percent of the population -- will suffer at some point in their lifetimes from obsessive-compulsive disorder, a disorder characterized by recurrent, intrusive, and disturbing thoughts (obsessions), and/or stereotyped recurrent behaviors (compulsions).
