Gut Bacteria May Lead to the Development of Alzheimer's Disease

A healthy gut is important for your well-being. It keeps your digestive system functioning efficiently. There are various good bacteria that reside in your stomach which help in the process of digestion. They are a complex group of microorganisms that work in various ways to carry out various metabolic functions. There are also various food products that are available in the stores which can improve your gut bacteria. While the benefits of gut bacteria have been spoken about in length by health experts, a recent study brings about another side to these microorganisms. According to a new study done by the Lund University in Sweden, the bacteria in your gut may play a major role in the development of Alzheimer’s disease – the most common form of dementia. The study may initiate new ways for treatment and preventing the neurodegenerative disease.

The researchers found that mice suffering from Alzheimer’s have a different composition of intestinal bacteria compared to mice that are healthy. Mice without bacteria had a significantly smaller amount of beta-amyloid plaque – lumps that form at the nerve fibres in cases of Alzheimer’s disease – in the brain.

 

“Our study is unique as it shows a direct causal link between gut bacteria and Alzheimer’s disease. It was striking that the mice which completely lacked bacteria developed much less plaque in the brain,” said Frida Fak Hallenius from the Lund University.

“The results mean that we can now begin researching ways to prevent the disease and delay the onset,” Hallenius added.

 

Gut bacteria has a major impact on how people feel through the interaction between the immune system, the intestinal mucosa and our diet. The composition of the gut microbiota depends on which bacteria we receive at birth, our genes and our diet, the researchers said. In the study, the team also studied Alzheimer’s disease in mice that completely lacked bacteria to further test the relationship between intestinal bacteria and the disease. They transferred intestinal bacteria from diseased mice to germ-free mice. The mice developed more beta-amyloid plaques in the brain compared to if they had received bacteria from healthy mice, the researchers noted.
