A new small yet comprehensive study has shown that supplementing a daily glass of milk with some specific probiotics, may enhance cognition in people with Alzheimer’s disease.
In this study, published in the Journal Frontiers in Neuroscience, 60 people who had been diagnosed with Alzheimer’s disease (aged between 60-95 years) were allocated into two different treatment groups. The 12-week trial was simple in design, one group received a glass of milk daily with a mixture of probiotics, and the other did not – and was asked to just drink a glass of milk. Importantly, participants were requested not to change their ordinary physical activity and not to take any nutritional supplements during the trial.
The research team found that those who drank the milk containing the probiotics showed improvement in their mini-mental state examination (MMSE) scores over time, and in some cases had a lower number of blood biomarkers which, when risen, are indicative of Alzheimer’s disease, and reduced levels of oxidative stress in the brain. It should be stressed though that there was much variety in results between individuals which make it difficult to make strong conclusions based on this small study.
What is so good about probiotics?
The most common form of commercially available probiotic you’ll probably recognise goes by the name of Yakult. Yakult contains many millions of probiotics (or gut bacteria) which assist in stimulating the digestive process and aid food absorption. It is even suggested that probiotics can enhance the immune system and remove harmful bacteria.
While this very small study (in comparison to large scale clinical trials involving thousands of participants) does not suggest going out and buying Yakult and drinking it daily (it should be reminded that this study didn’t even test Yakult), it does add to a growing body of evidence suggesting gut health is linked to brain health.
Based on these new and very preliminary findings, researchers now plan on further assessing the link between probiotics and brain function before providing further advice on this outcome.
It should be stressed that if you plan on changing your diet or nutrition intake to consult a health professional before doing so.
Hi Sharon, I'm sorry but I don't know which probiotic was used. You might need to go to the original research to find out. Good luck, The Dementia Daily Team
