A new study, led by Professor Pernilla Wittung-Stafshede from the Chalmers University of Technology, Gothenburg, suggests that eating cod, herring, and red snapper may help in preventing Parkinson’s disease.
The researchers also highlight that fish is normally a lot more nutritious at the end of summer because of increased metabolic activity.
One of the study researchers Nathalie Scheers says: “Levels of parvalbumin [a protein that prevents the formation of protein structures associated with the tremor disorder] are much higher in fish after they had a lot of sun, so it could be worthwhile increasing consumption during autumn.”
Other conditions linked to protein formation in the brain such as Alzheimer’s and Huntington’s diseases may also benefit from higher fish consumption. The researchers plan to investigate the potential of parvalbumin in the future studies.
A group of researchers claims that they are close to developing a blood test that will be able to detect the Alzheimer’s disease long before the symptoms appear.
One of the main problems in treating the Alzheimer’s disease is that it is always diagnosed at a relatively late stage as the symptoms may develop over the many years.
In a recent study, published in the journal EMBO Molecular Medicine, researchers wanted to understand whether measuring the relative levels of healthy and pathological amyloid-beta in the blood could identify Alzheimer’s disease at its early stages.
The initial phase of the study demonstrated promising results – in participants who showed subtle early symptoms of the Alzheimer’s disease, the test detected changes in levels of amyloid-beta that associated with abnormal deposits visualized using brain scans.
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.
