According to the research, conducted by Rutgers University, US, coffee could fight both Parkinson’s disease and a form of dementia called dementia with Lewy bodies (DLB).
For the study, a team of scientists used a mice model including rodents with the risk of developing both diseases. The tests showed that two compounds found in coffee, caffeine and EHT, prevented alpha-synuclein from building-up after just six months.
At the present moment, the researchers hope that these two compounds found in coffee could be integrated into a drug to treat Parkinson’s disease and dementia with Lewy bodies in humans. These diseases are considered incurable.
A new study, conducted by scientists from the Karolinska Institute and Stockholm University, Sweden, suggests that atrial fibrillation is associated with the increased risk of developing dementia.
For the study, a team of researchers has analyzed the data of 2,685 participants whose average age was 73 years. The scientists interviewed the participants and conducted a medical examination at baseline. After that, the participants younger than 78 was followed for 6 years, and the participants older than 78 were examined every 3 years.
The researchers explain in their paper: “Assuming that there was a cause-and-effect relationship between using blood thinners and the reduced risk of dementia, we estimated that about 54 percent of the dementia cases would have been hypothetically prevented if all of the people with atrial fibrillation had been taking blood thinners.”
A new study, conducted by researchers from Jaume I University in Castelló de la Plana, Spain, suggests that a hormone found in plants can reverse the brain damage caused by a high-fat diet.
For their study, the researchers fed mice with high-fat foods. The rodents developed inflammation of the nervous system which is similar to the Alzheimer’s disease. However, when plants were added to the diet, the damage was reversed due to the plant hormone called abscisic acid.
In the nearest future, the Spanish researchers are planning to investigate the common causes behind such conditions as dementia and insulin resistance.
According to a French study, recently published in JAMA, senior people with better heart health have the lower risk of developing dementia and cognitive decline.
For the study, the researchers followed 6,626 people aged 65 years and over for 8.5 years on average. The followed people lived in Bordeaux, Dijon, and Montpellier (France). The average age was 73.7 years. None of the followed had dementia or cardiovascular disease.
The researchers conclude in their study: “These findings may support the promotion of cardiovascular health to prevent risk factors associated with cognitive decline and dementia.”
To maintain good cardiovascular health, you should comply with the following recommendations: give up smoking; be physically active; include vegetables, fruit, and fish into your diet; keep your weight healthy; keep an eye on your blood pressure, cholesterol, and blood sugar.
Our brain combines smell with the information about space and time to form episodic vivid memories, according to a recent research, published in the journal Nature Communications. These findings can help improve sniff tests for the Alzheimer’s disease.
In the course of the study, a team of researchers examined the role of the anterior olfactory nucleus (AON) in memory using a mouse model in a range of experiments. They discovered a previously unknown neural pathway between the hippocampus and the AON.
Study co-author Afif Aqrabawi says: “[The findings demonstrate] that we now understand which circuits in the brain govern the episodic memory for the smell. The circuit can now be used as a model to study fundamental aspects of human episodic memory and the other odor memory deficits seen in neurogenerative conditions.”
