This Dietary Supplement Improves Cognition And Fights Dementia

The dietary supplement has already been linked to lower depression, treating autism and reducing social anxiety.

For the first time, probiotics have been shown to improve cognition and fight dementia.

Probiotics are live bacteria that can be taken as dietary supplements.

The study showed that just 12 weeks of daily doses of Lactobacillus and Bifidobacteriumbacteria had a beneficial effect.

Elderly people with Alzheimer’s showed improvements in cognition.

Probiotics have already been linked to:

• Stopping sadness becoming depression,
• treating autism,
• and reducing social anxiety.

Professor Mahmoud Salami, a study author, said:

“In a previous study, we showed that probiotic treatment improves the impaired spatial learning and memory in diabetic rats, but this is the first time that probiotic supplementation has been shown to benefit cognition in cognitively impaired humans.”

Probiotic dietary supplement

The study compared two groups of Alzheimer’s patients, who were between 60 and 95 years-old.

Half received milk that was fortified with four probiotic bacteria:

• Lactobacillus acidophilus,
• L. casei,
• L. fermentum,
• and Bifidobacterium bifidum.

The others received just the milk.

Along with improvements in cognition, the researchers also saw improvements in physiological measures, such as triglyceride levels.

Professor Salami said:

“These findings indicate that change in the metabolic adjustments might be a mechanism by which probiotics affect Alzheimer’s and possibly other neurological disorders.

We plan to look at these mechanisms in greater detail in our next study.”

Professor Walter Lukiw, who reviewed the study, said:

“This early study is interesting and important because it provides evidence for gastrointestinal (GI) tract microbiome components playing a role in neurological function, and indicates that probiotics can in principle improve human cognition.

This is in line with some of our recent studies which indicate that the GI tract microbiome in Alzheimer’s is significantly altered in composition when compared to age-matched controls, and that both the GI tract and blood-brain barriersbecome significantly more leaky with aging, thus allowing GI tract microbial exudates (e.g. amyloids, lipopolysaccharides, endotoxins and small non-coding RNAs) to access Central Nervous System compartments.”
