Mosquito-Borne Virus May Lead to Severe Brain Infection

The mosquito-borne virus chikungunya may lead to severe brain infection and even death in infants and people over 65, according to a new study that reviewed a chikungunya outbreak on Reunion Island off the coast of Madagascar in 2005-2006. The study is published in the November 25, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology. Many cases have occurred in the United States in people who acquired the virus while traveling, but the first locally transmitted case in the U.S. occurred in Florida in July.

Neurological Underpinnings of Schizophrenia Just as Complex as the Disorder Itself

Schizophrenia is notoriously difficult to diagnose and treat, in large part because it manifests differently in different people. A new study helps explain why. Researchers at UNC have created a map that shows how specific schizophrenia symptoms are linked to distinct brain circuits.

Better Detection of Concussion in Young Football Players

Researcher Christian Duval, PhD, and his team have developed a new, simple and non-invasive approach to create a biomechanical and cognitive profile of football players and more quickly and accurately detect concussions in these individuals.

UAB Study Says Alzheimer’s Plaques Can Also Affect the Brain’s Blood Vessels

VascularAmyloid3Dreconstruct91105_009-01.jpg

Amyloid beta, the plaque that accumulates in the brains of people with Alzheimer’s disease, may also contribute to Alzheimer’s by interfering with normal blood flow in the brain, according to investigators UAB. In findings published Nov. 23 in the journal Brain, the team shows that when amyloid beta accumulates around blood vessels — where it is known as vascular amyloid — it appears to prevent the brain from properly regulating blood flow, which is essential to normal brain function.

Virginia Tech Neuroscientists Take Step in Understanding Cause of Alzheimer's Symptoms

Virginia Tech Carilion Research Institute scientists have uncovered a mechanism in the brain that could account for some of the neural degeneration and memory loss in people with Alzheimer’s disease. The researchers, together with scientists at the University of Alabama at Birmingham School of Medicine, discovered that a common symptom of Alzheimer’s disease – the accumulation of amyloid plaques along blood vessels – could be disrupting blood flow in the brain.

And When the Bubbles Burst, Thunder in Neurons

4-DFD-Franck-TBI.jpg

In the fleeting moments after a liquid is subjected to a sudden change in pressure, microscopic bubbles rapidly form and collapse in a process known as cavitation. In the human brain, this is believed to be a mechanistic cause of traumatic brain injury, or TBI, but the phenomenon has yet to be directly observed in brain tissue because the bubbles appear and disappear within microseconds. To address this, researchers are seeking to understand how cavitation might injure neurons by using a 3-D imaging system coupled with a diffraction grating to examine their post-exposure morphology. They will present their recent findings APS’s DFD 2015 Meeting.

Six University of California, San Diego professors have been named Fellows of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. They are among 347 members selected this year by colleagues in their disciplines to be honored for “scientifically or socially distinguished efforts to advance science or its applications.”
