Clinton Herald: Ability to balance on one leg may reflect brain health

Struggling to balance on one leg for 20 seconds or longer was linked to an increased risk for small blood vessel damage in the brain and reduced cognitive function in otherwise healthy people with no clinical symptoms, according to new research in the American Heart Association’s journal Stroke. “Our study found that the ability to […]

Daily Mail: The perfect excuse for a pint! Regular beer-drinking could help ward off Alzheimer’s and Parkinsons, say scientists

Regularly drinking beer could help slow dementia, research suggests. Scientists have discovered an ingredient in hops which they think could slow the progression of degenerative diseases such as Alzheimer’s and Parkinson’s. In laboratory experiments they found that the chemical, called xanthohumol or Xn, could help protect brain cells from oxidative damage associated with dementia. The […]

Medical Xpress: Novel eye-tracking technology detects concussions and head injury severity

Neuroscientists and concussion experts from NYU Langone and elsewhere, in a study publishing online January 29 in Journal of Neurotrauma, present a unique, simple and objective diagnostic tool for concussion that can be utilized in the emergency room or, one day, on the sidelines at sporting events. The study utilized a novel eye-tracking device to […]

Medical Xpress: Altered dopamine signaling a clue to autism

Newly discovered genetic variations linked to autism spectrum disorder (ASD) disrupt the function of the dopamine transporter, suggesting that altered dopamine signaling contributes to this common developmental condition, according to a Vanderbilt University-led research team. Two different inherited genetic variations in two different families of children with ASD “converged” to produce the same changes in […]

CBS News: Study: Some kids with autism show improvement by age 6

More than 10 percent of preschool-age children diagnosed with autism saw some improvement in their symptoms by age 6 and 20 percent of the children made some gains in everyday functioning, a new study found. Canadian researchers followed 421 children from diagnosis (between ages 2 and 4) until age 6, collecting information at four points […]

EurekAlert: Common pesticide may increase risk of ADHD

A commonly used pesticide may alter the development of the brain’s dopamine system — responsible for emotional expression and cognitive function – and increase the risk of attention deficit hyperactivity disorder in children, according to a new Rutgers study. The research published Wednesday in the Journal of the Federation of American Societies for Experimental Biology […]

Live Science: People with Dementia May Have Hidden Talents, Strange Case Shows

A 60-year-old businessman lost his job and much of his personality to dementia. But despite his mentally debilitating condition, he learned to play the saxophone for the first time in his life, and played exceptionally well, according to a new report of his case. The Korean man, called J.K. in the report, had developed a […]

Medical Xpress: New deep-brain imaging reveals separate functions for nearly identical neurons

Researchers at the UNC School of Medicine have used new deep-brain imaging techniques to link the activity of individual, genetically similar neurons to particular behaviors of mice. Specifically, for the first time ever scientists watched as one neuron was activated when a mouse searched for food while a nearly identical neuron next to it remained […]

Medical Xpress: Sex differences found in brain mechanisms important for learning

Women tend to become addicted to drugs and relapse faster than men, though the biological reasons are not completely clear. Now, investigators at the Nathan Kline Institute for Psychiatric Research and Weill Cornell Medical College have discovered that high levels of estrogen may lead to a unique kind of learning that could explain why women […]
