A new study from the University of California, Los Angeles, suggests that short walks every day can help to keep the brain healthy, supporting the overall resilience of cognitive function.
For the study, a team of scientists selected 26 adults aged 60 and over. The participants were divided into two groups, the first was with low physical activity where people walked 4,000 or fewer steps; the second group was with high physical activity, where people walked more than 4,000 steps per day.
The researchers discovered that people who walked more than 4,000 steps (approximately 3 km) every day had thicker hippocampi and thicker associated brain regions compared to people from the low physical activity.
A new study suggests that an extract of ginkgo biloba in combination with aspirin may promote cognitive functioning after a stroke. Ginkgo biloba extract is an herbal supplement received from the ginkgo tree, also known as maidenhair tree, native to China.
For the study, a team of scientists from China enrolled 348 adults with average age 64 from five hospitals in China Jiangsu Province. All the patients experienced an ischemic stroke within the past 7 days.
The scientists note that at 12 and 30 days after treatment, those patients who were treated with both ginkgo biloba extract and aspirin showed better functional capacity that those who received aspirin only demonstrating fewer neurobiological impairments such as speech problems and muscle weakness.
The Chinese researchers write in their paper: “The study demonstrated that patients with stroke who received GBE (Ginkgo biloba extract] and aspirin manifested better memory function, executive functions, neurological function, and daily life. Additionally, the safety data analysis demonstrated that GBE did not increase the incidence of adverse events.”
According to a new study from the National Eye Institute, US, the risk of developing glaucoma, a common eye disease in senior people, was lower in those who drank hot tea on a daily basis.
A team of scientists analyzed data received from the 2005–2006 National Health and Nutrition Examination Survey, which included the medical data of nearly 10,000 people. Having analyzed the received data, the researchers discovered that the participant who drank hot tea every day had 74% lower risk of developing glaucoma.
However, the team concluded that further research is needed to establish the importance of these findings and whether hot tea consumption may play a role in the prevention of glaucoma.
A new study, published in the journal of the American Geriatrics Society, suggests that older adults that leaving home every day have more chances to live longer compared to those who stay indoors.
The study included data of 3,375 adults aged between 70 and 90 years all of whom were involved in the 1990–2015 Jerusalem Longitudinal Study.
Having analyzed the received data, the scientists found that senior adults who left their houses regularly were at the lowest risk of death, while those seniors who left their houses seldom were at the highest risk of death.
Dr. Jacobs says: “What is interesting is that the improved survival associated with getting out of the house frequently was also observed among people with low levels of physical activity, and even those with impaired mobility. Resilient individuals remain engaged, irrespective of their physical limitations.”
A new study from Harvard University discovered that one brisk walk at least once a week can reduce a senior women’s risk of early death by 70%.
For the study, a team of researchers analyzed data from more than 17,000 women aged over 70. The analysis showed that more moderate to vigorous intensity physical activity – such as brisk walking – associated with around 60–70% lower risk of death at the end of the study.
The first author of the study Prof. I-Min Lee from Harvard University’s medical and public health schools in the US says: “We hope to continue this study in the future to examine other health outcomes, and particularly to investigate the details of how much and what kinds of activity are healthful.”
