Probiotics Help Mild Cognitive Impairment

Acupuncture in Exeter: Probiotics help mild cognitive impairment Researchers at the University of North Carolina have presented a study at July’s American Society for Nutrition conference, suggesting that a particular probiotic may help mild cognitive impairment, and cognitive performance more generally.

They devised a double-blind, randomised, controlled trial in which 169 middle-aged (aged 52 to 59) and older (60 to 75) adults were enrolled. At the start of the trial, participants were assessed as either having normal cognition or mild cognitive impairment, and samples of their gut microbiome were taken. They were then randomised to receive either probiotics or placebo for three months. The probiotic used was Lactobacillus rhamnosus GG (LGG).

Analysis showed that participants with mild cognitive impairment, had significantly higher levels of Prevotella bacteria at outset. Those subjects who then took LGG were found after three months to exhibit reduced Prevotella populations, and this correlated with improved cognitive function. The researchers conclude that the gut microbiome profile may in future be used as an early indicator of mild cognitive impairment, and that it may be manipulated to improve cognitive performance.

I offer traditional Chinese acupuncture in Exeter, from a tranquil clinic a mile from the city centre, and next to the University of Exeter. I graduated originally from the London School of Acupuncture and Traditional Chinese Medicine’s 3 year full time Acupuncture Diploma (DipAc) course. I am on the practitioners register of the British Acupuncture Council (MBAcC), a regulatory and professional body with an entry standard of a full three year undergraduate degree level training. I have worked in a hospital in south west China, deepening my knowledge and using acupuncture and Chinese massage (tuina) as the treatment of choice in its country of origin. I have taught Chinese medicine in colleges, the NHS and at university level. I also practise Qi Gong, and Chinese dietary therapy, that is the medicinal use of ordinary foods, chosen to help achieve particular therapeutic effects in different individuals.
