Dec 19, 2017: A new study has dashed hopes that people may be able to protect themselves from dementia through medicine, diet or exercise.
“To put it simply, all evidence indicates that there is no magic bullet,” Dr. Eric Larson wrote in the Annals of Internal Medicine.
The study outlined in the medical journal looked at four types of intervention to try to prevent dementia — prescription drugs, exercise, cognitive training, and nonprescription vitamins and supplements.
Researchers found none worked.
The Lancet, a British medical journal, reported earlier this year that about one-third of dementia cases could be linked to such conditions as cigarette smoking, high blood pressure, obesity, a lack of exercise and depression.
While Larson said there was no simple answer to the prevention of dementia, he highly recommended a commonsense, healthful lifestyle that may help delay the disease. It would involve exercising regularly, refraining from smoking, eating a healthful diet and taking part in activities that stimulate the brain. (VOA)
Existence of alien life is always been a subject of curiosity
Language in the coverage of these events showed significantly more positive than negative emotions
Participants’ responses showed significantly more positive than negative emotions, both when contemplating their own reactions and those of humanity as a whole
Have you wondered how would people react if scientists ever detect alien life in the universe? Humans would be “pretty upbeat” and welcome the news, finds a study.
Various studies have in the past speculated about how humans might respond to this kind of news, but until now, there has been almost no systematic empirical research.
In a pilot study, scientists at the Arizona State University analysed various media reports of “alien announcements”, including the appearance of the “alien” interstellar asteroid Oumuamua, that suggest the potential for alien life in our solar system.
Language in the coverage of these events showed significantly more positive than negative emotions.
“If we came face to face with life outside of Earth, we would actually be pretty upbeat about it,” said assistant professor Michael Varnum.
The results are in stark difference to the warnings from scientist Stephen Hawking who thinks aliens will not like being contacted by humans and that if we ever try to contact them they could kill humans.
In another two separate studies, nearly 1,000 people were asked to write about their own hypothetical reactions to an announcement that alien microbial life had been discovered, as well as to write about their reactions on past news coverage of scientific discoveries.
Participants’ responses showed significantly more positive than negative emotions, both when contemplating their own reactions and those of humanity as a whole.
For the study, published in the American Journal of Hypertension, researchers examined 3,119 non-smoking postmenopausal women aged 50 years or older in the 2010-2011 Korea National Health and Nutrition Examination Survey
