Male infertility linked to mortality, study shows

Male infertility linked to mortality, study shows

Men who are infertile because of defects in their semen appear to be at increased risk of dying sooner than men with normal semen, according to a study led by a researcher at the Stanford University School of Medicine. Men with two or more abnormalities in their semen were more than twice as likely to die over a roughly eight-year period as men who had normal semen, the study found. Continue reading

Older migraine sufferers may have more silent brain injury

Older migraine sufferers may have more silent brain injury

Older migraine sufferers may be more likely to have silent brain injury, according to research published in the American Heart Association’s journal Stroke. In a new study, people with a history of migraine headaches had double the odds of ischemic silent brain infarction compared to people who said they didn’t have migraines. Silent brain infarction is a brain injury likely caused by a blood clot interrupting blood flow to brain tissue Continue reading

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

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
