Shocking Relationship Discovered Between Posture and Cognitive Decline



Through a comprehensive survey of people between the ages of 50 and 89, it was determined if cognitive decline might be detected by sagittal spinal balance assessment based on a radiological technique. Researchers from Shinshu University found associations between sagittal vertical axis (SVA) anteriorization, advanced age, and poor cognitive function. The sagittal vertical axis is defined as the distance between the posterior superior sacral end plate to a vertical plumbline dropped from the centroid of the C7 vertebral body.

The greater the head and neck protrude in front of the pelvis when viewed from the side, the greater the likelihood that subjects may exhibit signs of mild cognitive deterioration (the greater the length). The SVA was associated with age-independent cognitive deterioration in men. Regardless of age, ladies with SVA equal to or greater than 70mm had a higher prevalence of cognitive deterioration.

A person with mild cognitive impairment is one who experiences mild cognitive problems but does not have dementia. By identifying moderate cognitive impairment at a stage that can be reversed, dementia, frailty, and bedridden conditions may be prevented in locations where expensive specialist testing equipment or additional medical testing time is restricted for the senior population.

The first author, occupational therapist Hikaru Nishimura, investigates problems faced by the elderly from a rehabilitation perspective. Exercise training may slow or even halt the growth of dementia in older people.

Poor posture in the elderly is a sign of "frailty," according to corresponding author Doctor Shota Ikegami of Shinshu University. Through posture screening, it is possible to identify hidden cognitive deterioration, a factor in frailty. For the mass survey, older persons in Obuse, Nagano, were looked at. It was discovered that among Japanese elderly persons, those with anteriorization of the spine had a higher likelihood of also experiencing a deterioration in cognitive performance.

Age and the level of spinal misalignment were combined to accurately identify cognitive deterioration. Males with SVA 100 mm at any age, SVA 90 mm at 70 years, and SVA 70 mm at 80 years are more likely to experience cognitive decline than females with SVA 70 mm at any age.

In Japan, the Nagano prefecture has among of the best health lifespan rates. Through rehabilitation interventions for frailty discovered during screenings, clinicians seek to avoid the need for care in the future with the help of this study and others.
The Japanese Society for Musculoskeletal Medicine, the Shinshu Public Utility Foundation for Promotion of Medical Sciences, the Japan Orthopaedics and Traumatology Research Foundation, Inc., the Shinshu University Hospital, and the Nakatomi Foundation provided funding for the study.

Do You Sleep on Your Back or Side? Here's The Research on 'Optimal' Sleep Positions

Image
William Dement, a renowned sleep researcher at Stanford University, is quoted as saying that after 50 years of study, the only reason he can think of for why we sleep is "because we become sleepy." Sleep certainly matters for our health and wellbeing even though it may be, as one researcher put it, "the sole major habit in quest of a function." Do we, however, have it right? What do studies on sleeping positions say? Is there a proper sleeping position? The majority of people favor sleeping on their side. This is encouraging news because people who sleep on their backs are more likely to have trouble falling asleep or breathing during the night. Most of the time, we have a tendency to shift around quite a bit at night. According to a study involving 664 sleepers, on average, participants slept on their side 54% of the time, their back 37% of the time, and their front 7% of the time. Males are more likely to change positions throughout the night and move their arms, ...

The Science of Beards

Image
Here are a few facts that scientists have learned about beards as the world prepares to celebrate amazing facial hair on World Beard Day (September 3). Strong Manly Beard Men who have beards appear to be more dominant, aggressive, and strong, according to numerous studies[1][2][3] that have been conducted. In fact, men claim that growing facial hair makes them feel[4] more manly. Men who choose to grow beards tend to have higher testosterone levels than men who choose to keep their faces clean-shaven, according to research. They are also more likely to be hostile sexists, or to support the patriarchy and male dominance, as well as to believe that women belong in the kitchen, according to research on this topic. The beards (and muscles) on these males might be used to enforce gender roles. Professor R. D. Guthrie proposed in his book "Evolution of human threat display organs" from the 1970s that beards could be utilized to scare male rivals by improving aggressive and threaten...

Scientists Uncover a Surprising Connection Between Appetite and Sun Exposure

Image
Recent studies from Tel Aviv University show that women are not affected by sun exposure on their hunger levels, but males are. The study shows how the metabolic pathway is engaged differently in men and women. It was carried out utilizing lab models. Males of both animal and human species, as well as those exposed to the sun, are reportedly triggered to produce a protein called p53 that repairs any DNA damage that may have been done to the skin as a result of the exposure. The body produces the hunger-inducing hormone ghrelin in response to p53 activation. In females, the hormone estrogen stops p53 from interacting with ghrelin, preventing the desire to eat after being in the sun. The ground-breaking investigation was directed by professor Carmit Levy and Ph.D. candidate Shivang Parikh of the Department of Human Genetics and Biochemistry at TAU's Sackler Faculty of Medicine. In addition to the Tel Aviv Sourasky (Ichilov), Assuta, Meir, and Sheba Medical Centers, Drs. Yiftach Gepne...
