Innovative study utilizing video games shows sleep apnea may affect memory of everyday events

Innovative study utilizing video games shows sleep apnea may affect memory of everyday events

Sleep apnea may affect your ability to form new spatial memories, such as remembering where you parked your car, new research led by NYU Langone Medical Center sleep specialists suggests. The study, published online Oct. 29 in Journal of Neuroscience , demonstrates through the playing of a specific video game that disruption of rapid eye movement (REM) sleep as a consequence of sleep apnea impairs spatial memory in humans even when other sleep stages are intact Continue reading

Traumatic brain injury associated with increased dementia risk in older adults

Traumatic brain injury associated with increased dementia risk in older adults

Traumatic brain injury (TBI) appears to be associated with an increased risk of dementia in adults 55 years and older, according to a study published online by JAMA Neurology . Controversy exists about whether there is a link between a single TBI and the risk of developing dementia because of conflicting study results Continue reading

Dietary cocoa flavanols reverse age-related memory decline in mice

Dietary cocoa flavanols reverse age-related memory decline in mice

Dietary cocoa flavanols — naturally occurring bioactives found in cocoa — reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. The study, published today in the advance online issue of Nature Neuroscience , provides the first direct evidence that one component of age-related memory decline in humans is caused by changes in a specific region of the brain and that this form of memory decline can be improved by a dietary intervention Continue reading

Costs to treat bleeding strokes increases 10 years later

Costs to treat bleeding strokes increases 10 years later

Costs to treat strokes caused by bleeding in the brain may increase significantly 10 years later, according to a study in the American Heart Association journal Stroke. The Australian study is the first to include 10 years of follow-up data on stroke cost estimates, which may also apply to the United States, researchers said Continue reading

Fight against Alzheimer’s disease: New research on walnuts

Fight against Alzheimer’s disease: New research on walnuts

A new animal study published in the Journal of Alzheimer’s Disease indicates that a diet including walnuts may have a beneficial effect in reducing the risk, delaying the onset, slowing the progression of, or preventing Alzheimer’s disease. Research led by Abha Chauhan, PhD, head of the Developmental Neuroscience Laboratory at the New York State Institute for Basic Research in Developmental Disabilities (IBR), found significant improvement in learning skills, memory, reducing anxiety, and motor development in mice fed a walnut-enriched diet Continue reading

Mental rest and reflection boost learning, study suggests

Mental rest and reflection boost learning, study suggests

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they’ve learned before, may boost later learning. Continue reading

See-through sensors open new window into the brain

Developing invisible implantable medical sensor arrays, a team of University of Wisconsin-Madison engineers has overcome a major technological hurdle in researchers’ efforts to understand the brain. The team described its technology, which has applications in fields ranging from neuroscience to cardiac care and even contact lenses, in the Oct. 20 issue of the online journal Nature Communications Continue reading

New mechanism that can lead to blindness discovered

New mechanism that can lead to blindness discovered

An important scientific breakthrough by a team of IRCM researchers led by Michel Cayouette, PhD, is being published by The Journal of Neuroscience . The Montréal scientists discovered that a protein found in the retina plays an essential role in the function and survival of light-sensing cells that are required for vision. These findings could have a significant impact on our understanding of retinal degenerative diseases that cause blindness Continue reading

Scientists sniff out unexpected role for stem cells in the brain

Scientists sniff out unexpected role for stem cells in the brain

For decades, scientists thought that neurons in the brain were born only during the early development period and could not be replenished. More recently, however, they discovered cells with the ability to divide and turn into new neurons in specific brain regions. The function of these neuroprogenitor cells remains an intense area of research Continue reading
