Probiotic Supplements Can Improve Cognitive Function

According to the results of a recent meta-analysis, completed by scientists from Jiangnan University in China, probiotic supplementation may improve cognitive function in people with mild cognitive impairment.Probiotic Supplements Can Improve Cognitive Function

A team of researchers sifted through 294 studies published between 1984 and early 2021 involving patients with Alzheimer’s or mild cognitive impairment (MCI), ultimately including just 8 articles for the systematic review and 7 for the meta-analysis.

The analysis of the selected articles showed that probiotic supplements improved cognitive function in people with MCI. However, the results were less impressive for participants with Alzheimer’s disease.

The authors conclude: “Compared with placebo or control interventions, probiotic supplementation considerably improved cognitive function in the participants with MCI, but it only caused a modest cognitive improvement in those with Alzheimer’s disease.”

Modified Keto Diet Linked to Lower Risk of Mild Cognitive Impairment

A new study, conducted by researchers from the Wake Forest School of Medicine, in Winston-Salem, U. S., finds that a diet, called the modified Mediterranean-style ketogenic diet may prevent mild cognitive impairment, which often leads to the development of Alzheimer’s, by creating a more healthful balance of the gut microbiota.Modified Keto Diet Linked to Lower Risk of the Mild Cognitive Impairment

This type of diet includes very few carbohydrates that used as fuel by the human body, and when the body is short on carbs, it starts to break its fat reserves to produce ketones as an alternative source of energy.

Principal investigator Hariom Yadav, Ph.D., an assistant professor of molecular medicine at Wake Forest comments the results of the study: “Although we do not fully understand how these fungi contribute to Alzheimer’s disease, this is the first study of its kind to reveal their role in our mental health, which we hope will ignite thinking in the scientific community to develop a better understanding of them in relation to Alzheimer’s disease.”

Bilingualism May Protect from Alzheimer’s Disease and MCI

A new study, published in the journal Neuropsychologia, finds that bilingualism makes changes in brain structure that are associated with resilience against the Alzheimer’s disease and mild cognitive impairment (MCI).bilingualism

The researchers included the following categories of participants: multilingual with MCI (34), monolingual with MCI (34), multilingual with the Alzheimer’s disease (13), monolingual with the Alzheimer’s disease (13). Having analyzed the received data, the researchers found that both multilingual patients with MCI and Alzheimer’s disease patients had thicker cortex than monolingual patients.

Lead study author Natalie Phillips, a professor in the Department of Psychology at Concordia University in Quebec, Canada, says: “Our new study contributes to the hypothesis that having two languages exercises specific brain regions and can increase cortical thickness and gray matter density.”
