Blueberries appear to reverse cognitive decline – healing practice

Protecting Brain Health from Wild Blueberries

blueberries seem one Improvement in cognitive performance which counteracts the cognitive decline that occurs naturally in old age and could thus also contribute to the protection against dementia.

In a new study by experts from University of North Carolina at Chapel Hill has studied how people with cognitive problems are affected when they use a Wild blueberry powder eat. The results can be found in the English-language journal “Nutritional Neuroscience“ to be read.

Research included people with cognitive problems

The new research is a so-called randomized, placebo-controlled, double-blind study. In the investigation Participants with cognitive problems randomly assigned to either a treatment or a control group.

In the process, cognitive difficulties were identified by the results of the so-called MoCA-Tests (Montreal Cognitive Assessment).

Participants consumed blueberry powder for six months

The participants in the treatment group took part over a period of six months a powder made from wild blueberries every day. In contrast, the participants in the control group only received a placebo powder. In addition, participants who did not have any cognitive problems were reference group included.

The participants were each at the beginning and at the end of the study with the help of the so-called Cambridge Neurological Test Automated Battery (CANTAB) and with a electrophysiological paradigm tested, the experts report.

Blueberries improved processing speed

According to the researchers, the results of the tests of specific cognitive abilities with the CANTAB showed that the processing speed improved in the group of people consuming blueberries compared to people who only received placebo powder.

The inclusion of blueberries eventually even led to one Improvement in processing speed on the level of the reference group, according to the team. The improvement in the processing speed through the intake of the blueberry powder by participants in the Age from 75 to 80 years most pronounced.

In summary, consuming the wild blueberry powder over a period of six months cognitive signs of aging counteracted by the speed of information processing was increased in older adults. (as)
