Binge drinking increases the risk of cognitive decline in older adults

Researchers from the Peninsula College of Medicine and Dentistry (PCMD), University of Exeter, will present the findings of a new study suggesting a link between binge drinking in older adults and the risk of developing dementia.

Actions don't always speak louder than words — At least, not when it comes to forgiveness

People are more likely to show forgiving behavior if they receive restitution, but they are more prone to report they have forgiven if they get an apology, according to Baylor University research published in the Journal of Positive Psychology.

The study underscores the importance of both restitution and apology and of using multiple measures for forgiveness, including behavior, said Jo-Ann Tsang, Ph.D., an associate professor of psychology and neuroscience in Baylor's College of Arts & Sciences.

Study identifies how muscles are paralyzed during sleep

Washington, D.C. — Two powerful brain chemical systems work together to paralyze skeletal muscles during rapid eye movement (REM) sleep, according to new research in the July 18 issue of The Journal of Neuroscience. The finding may help scientists better understand and treat sleep disorders, including narcolepsy, tooth grinding, and REM sleep behavior disorder.

Modified tPA could be effective stroke treatment without bleeding risk

Even when its clot-dissolving powers are removed, the stroke drug tPA can still protect brain cells from the loss of oxygen and glucose induced by a stroke, researchers have discovered.

The finding suggests that a modified version of tPA could provide benefits to patients who have experienced a stroke, without increasing the risk of bleeding.

The results will be published in the Journal of Neuroscience.

Experimental drug may extend therapeutic window for stroke

LOS ANGELES — A team led by a physician-scientist at the University of Southern California (USC) has created an experimental drug that reduces brain damage and improves motor skills among stroke-afflicted rodents when given with federally approved clot-busting therapy.

Clinical trials to test the safety of the drug in people are expected to start later this summer.

Drug shown to improve memory in those with Down syndrome

AURORA, Colo. (July 17, 2012) –Researchers at the University of Colorado School of Medicine have found a drug that boosts memory function in those with Down syndrome, a major milestone in the treatment of this genetic disorder that could significantly improve quality of life.

Musical glove improves sensation, mobility for people with spinal cord injury

Markow worked with individuals with SCI who had limited feeling or movement in their hands. Each suffered a spinal injury more than a year prior to the study. The eight-week project required study participants to practice playing the piano for 30 minutes, three times a week. Half used the MMT glove to practice; half did not.

Infants' recognition of speech more sophisticated than previously known, NYU researchers find

The ability of infants to recognize speech is more sophisticated than previously known, researchers in New York University's Department of Psychology have found. Their study, which appears in the journal Developmental Psychology, showed that infants, as early as nine months old, could make distinctions between speech and non-speech sounds in both humans and animals.

Johns Hopkins researchers link 2 biological risk factors for schizophrenia

Johns Hopkins researchers say they have discovered a cause-and-effect relationship between two well-established biological risk factors for schizophrenia previously believed to be independent of one another.

The findings could eventually lead researchers to develop better drugs to treat the cognitive dysfunction associated with schizophrenia and possibly other mental illnesses.

Sodium buildup in brain linked to disability in multiple sclerosis

OAK BROOK, Ill. – A buildup of sodium in the brain detected by magnetic resonance imaging (MRI) may be a biomarker for the degeneration of nerve cells that occurs in patients with multiple sclerosis (MS), according to a new study published online in the journal Radiology.

Amnestic mild cognitive impairment doubles risk of death

July 16, 2012 – (BRONX, NY) – Researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that people with a form of mild cognitive impairment (MCI), a risk factor for developing Alzheimer's disease, have twice the risk of dying compared with cognitively normal people. Those with dementia have three times the risk. The findings are being presented at the Alzheimer's Association International Conference in Vancouver this week.

Poor people value marriage as much as the middle class and rich, study shows

Poor people hold more traditional values toward marriage and divorce than people with moderate and higher incomes, UCLA psychologists report in the current issue of the Journal of Marriage and Family.

The findings are based on a large survey about marriage, relationships and values, analyzed across income groups. They raise questions about how effectively some $1billion in government spending to promote the value of marriage among the poor is being spent.

New York Stem Cell Foundation scientists featured for new model of Alzheimer's disease

NEW YORK, NY (July 16, 2012) – A team of scientists at The New York Stem Cell Foundation (NYSCF) Laboratory led by Scott Noggle, PhD, NYSCF–Charles Evans Senior Research Fellow for Alzheimer's Disease, has developed the first cell-based model of Alzheimer's disease (AD) by reprogramming skin cells of Alzheimer's patients to become brain cells that are affected in Alzheimer's. This will allow researchers to work directly on living brain cells suffering from Alzheimer's, which until now had not been possible. Andrew Sproul, PhD, a postdoctoral associate in Dr.

LINDSAY: The future of medical education

Researchers at the University of Calgary have created a new, interactive tool that will change the way medical education is taught.

LINDSAY, named after Dr. Lindsay Kimmett, a bright, promising medical student who died in a car crash, is a virtual human that uses a variety of touch interfaces to help students learn anatomy and physiology in 3D.

Low-cal diet's effects seen in fly brain, mouthpart

SAN ANTONIO (July 16, 2012) — A novel technique for measuring tiny, rapid-fire secretions in the brains and mouthparts of fruit flies (drosophila) is providing insights into the beneficial effects of eating less — information that ultimately could help people suffering from neuromuscular disorders.

Using the method, researchers uncovered never-before-seen brain chemistry that helps explain why fruit flies genetically manipulated to mimic conditions such as Parkinson's disease and myasthenia gravis are more vigorous and live longer when fed a restricted diet.
