Recent research from Austria finds that senior adults, who regularly exercise, sticking to the WHO recommendations, perform their routine tasks more easily and are more independent.
For the study, around 3,300 volunteers aged 65 years and over from Austria were included. The researchers assigned them to perform different types of physical activity including 150 minutes of moderate-intensity aerobic physical activity, or 75 minutes of intensive aerobic physical activity, within a week. Muscle strengthening activities also were added.
The scientists also measured their ability to perform everyday activities such as “activities of daily living/ADLs” (setting up, eating, drinking) and “instrumental activities of daily living/IADLs” (doing housework).
Having analyzed the received results, the researchers concluded that seniors who performed recommended units of exercise weekly were 3 times more likely to manage the ADLs and twice more likely to be able to perform IADLs.
For the study, a team of researchers analyzed medical records from 1947 patients from the University of Florida health clinic. They were older than 55 years and matched every AMD case. Also, 5841 patients were included as controls.
The authors of the study conclude in their paper: “We found that metformin, but not other medications, was associated with decreased odds of developing AMD. These findings suggest that metformin itself, and not other medications, has an important protective role.”
A recent research, published in the European Respiratory Journal, finds that sleep apnea, a common disorder that interferes with the breathing while sleeping, is connected to the changes in brain structure similar to changes seen in early dementia.
For the study, 83 participants were involved with the age from 51 to 88. They reported memory and mood problems to their doctors. None of them was diagnosed with obstructive sleep apnea (OSA) They underwent memory tests and MRI brain scans.
Having analyzed the received data, the scientists concluded that a low level of oxygen in blood during sleep was associated with the loss of thickness of the right and left temporal lobes of the brain. These brain structures play important role in memory processes and proved to be changed in dementia.

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.
