Antidepressant may slow Alzheimer’s disease

Antidepressant may slow Alzheimer’s disease

A commonly prescribed antidepressant can reduce production of the main ingredient in Alzheimer’s brain plaques, according to new research at Washington University School of Medicine in St. Continue reading

Human learning altered by electrical stimulation of dopamine neurons

Human learning altered by electrical stimulation of dopamine neurons

Stimulation of a certain population of neurons within the brain can alter the learning process, according to a team of neuroscientists and neurosurgeons at the University of Pennsylvania. A report in the Journal of Neuroscience describes for the first time that human learning can be modified by stimulation of dopamine-containing neurons in a deep brain structure known as the substantia nigra.

Brain may never fully recover from exposure to paint, glue, degreasers

Brain may never fully recover from exposure to paint, glue, degreasers

People who are exposed to paint, glue or degreaser fumes at work may experience memory and thinking problems in retirement, decades after their exposure, according to a study published in the May 13, 2014, print issue of Neurology ®, the medical journal of the American Academy of Neurology. “Our findings are particularly important because exposure to solvents is very common, even in industrialized countries like the United States.” said study author Erika L.

Longevity gene may boost brain power: Researchers discover the gene may enhance cognitive abilities

Longevity gene may boost brain power: Researchers discover the gene may enhance cognitive abilities

Scientists showed that people who have a variant of a longevity gene, called KLOTHO, have improved brain skills such as thinking, learning and memory regardless of their age, sex, or whether they have a genetic risk factor for Alzheimer’s disease. Increasing KLOTHO gene levels in mice made them smarter, possibly by increasing the strength of connections between nerve cells in the brain. The study was partly funded by the National Institutes of Health Continue reading

Common drug restores blood flow in deadly form of muscular dystrophy: Results from 10-patient case study

Common drug restores blood flow in deadly form of muscular dystrophy: Results from 10-patient case study

Cedars-Sinai Heart Institute researchers have found that a commonly prescribed drug restores blood flow to oxygen-starved muscles of boys with Duchenne muscular dystrophy, a genetic muscle-wasting disease that rarely is seen in girls but affects one in 3,500 male babies, profoundly shortening life expectancy. It is the most common fatal disease that affects children. Continue reading

Infusion of young blood recharges brains of old mice

Infusion of young blood recharges brains of old mice

Something — or some things — in the blood of young mice has the ability to restore mental capabilities in old mice, a new study by Stanford University School of Medicine investigators has found. If the same goes for humans, it could spell a new paradigm for recharging our aging brains, and it might mean new therapeutic approaches for treating dementias such as Alzheimer’s disease.

Pediatricians call for a Vitamin K tracking system for babies not getting shots

Pediatricians call for a Vitamin K tracking system for babies not getting shots

Doctors at Monroe Carell Jr. Children’s Hospital at Vanderbilt have seen a rise in late-onset vitamin K deficiency bleeding in young infants due to parents declining the shot at birth Continue reading
