Brain imaging changes in individuals with Down symdrome, may help advance Alzheimer trials
Apr 14, 2015
Researchers have characterized 3 different brain imaging changes in individuals with Down syndrome even before the onset of progressive memory and thinking problems. Their findings could help set the stage to evaluate promising treatments to slow down or prevent the onset of Alzheimer symptoms in these individuals, according to a study published in Alzheimer's & Dementia.
Characteristic pattern of protein deposits in brains of retired athletes who suffered concussions
Apr 06, 2015
A new UCLA study takes another step toward the early understanding of the degenerative brain condition chronic traumatic encephalopathy. Using a new imaging tool, researchers found a strikingly similar pattern of abnormal protein deposits in the brains of retired NFL players who suffered from concussions.
Researchers unravel mechanism that plays key role in sexual differentiation of brain
Mar 31, 2015
During prenatal development, the brains of most animals, including humans, develop specifically male or female characteristics. In most species, some portions of male and female brains are a different size, and may have a different number of neurons and synapses. However, scientists have known little about the details of how this differentiation occurs. Now, a new study by researchers at the University of Maryland School of Medicine has illuminated details about this process.
Researchers find promising new biomarkers for concussion
Mar 24, 2015
By looking at the molecular aftermath of concussion in an unusual way, a team of researchers at Brown University and the Lifespan health system has developed a candidate panel of blood biomarkers that can accurately signal mild traumatic brain injury within hours using standard, widely available lab arrays. The results appear in a new study in the Journal of Neurotrauma.
Magnetic brain stimulation
Mar 12, 2015
Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles—a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurologic diseases, without the need for implants or external connections.
New Alzheimer-related memory disorder identified
Nov 14, 2014
A multi-institutional study has defined and established criteria for a new neurologic disease closely resembling Alzheimer disease called primary age-related tauopathy (PART). Patients with PART develop cognitive impairment that can be indistinguishable from Alzheimer disease, but they lack amyloid plaques. Awareness of this neurologic disease will help doctors diagnose and develop more effective treatments for patients with different types of memory impairment.
