Researchers are studying ways to reduce cognitive decline
In a recent study, scientists found that three different forms of intervention can help prevent what is known as cognitive decline in those affected. For example, the negative cognitive effects of dementia can be reduced.
The researchers at the National Academies of Sciences, Engineering, and Medicine (NASEM) found that special interventions can prevent cognitive decline. The doctors released a press release on the results of their study.
Can these three measures slow the cognitive decline?
Cognitive training, an increase in physical activity and the control of blood pressure are fruitful measures to reduce cognitive decline, the authors explain. Evidence of the positive effects of these three interventions is encouraging, but not enough to justify a public campaign. Additional clinical studies are now required, the experts explain.
People can influence their cognitive decline through lifestyle changes
The public should have easy access to these intervention options and should be informed about their positive effects, the scientists claim. This allows people to make lifestyle choices to maintain brain health in old age, the researchers explain. The National Institute on Aging (NIA) had already carried out a systematic review in 2015. Various randomized controlled trials were analyzed for this. The results showed that three measures are particularly effective in reducing cognitive decline.
What are the different measures and what exactly do they do?
Cognitive training includes training programs for logic, problem-solving skills, reasoning and memory. Such training modules help to slow down age-related cognitive decline and the rate of development of dementia, the researchers explain. Another important point is the control of blood pressure in people with high blood pressure or high blood pressure, the authors explain further. This could help to slow the progress of dementia. The third intervention is increased physical activity, which can lead to various health benefits. These include, for example, the delay in age-related cognitive decline.
The interventions mentioned also protect against heart attacks and strokes
Cognitive training seems to only lead to a short-term slowdown in cognitive decline, doctors found in previous studies. However, there was also an investigation which came to the conclusion that the advantages are quite long-term. Monitoring blood pressure in turn protects against cardiovascular events such as heart attacks and strokes, the researchers say. Physical activity can lead to several benefits, such as preventing stroke and protecting the health of the human brain.
More research is needed
Further investigations should now check the actual effectiveness of the measures. Those at greatest risk of possible cognitive decline should be participants in these studies, the authors explain. In addition, population groups that were previously underrepresented in the studies had to be integrated into the studies. Long-term interventions that start at a young age should also be designed and reviewed, the researchers say. It could also help scientists deepen their knowledge of preventing or slowing cognitive decline. (as)
