Two out of every three people in the world have gut bacteria that increases their risk of developing Alzheimer's disease by up to 24%, a recent study found.

According to the British newspaper “The Times”, researchers at McGill University in Montreal found that people with symptoms of Helicobacter pylori infection had an 11% risk of developing Alzheimer's disease, which poses a “moderate to substantial” risk.

The paper said it analyzed data from more than four million people over the age of fifty in the United Kingdom, and found that the risk of developing Alzheimer's reached its highest rate of 24 percent seven to ten years after infection.

He pointed out that Helicobacter pylori is a bacteria found in contaminated water, food and soil, which is easily spread, is carried by around 40% of the UK and two-thirds of the world's population, and often causes no problems. Most people.

Symptoms of infection include abdominal pain, nausea, weight loss and ulcers.

Experts have yet to establish a link between this infection and Alzheimer's disease, but they believe it can travel to the brain and cause cell inflammation and neurodegeneration.

Dr Paul Brassard, senior author of the study, believes the results could prevent Alzheimer's disease, which affects the lives of 900,000 people in Britain.

Brassard added: “The number of people with dementia is expected to triple over the next forty years, yet we still lack effective treatment options for this disease.”

He continued: “We hope that the results of this study will provide insight into the role of Helicobacter pylori bacteria in the treatment of dementia, by developing prevention strategies that include individualized eradication programs to reduce infection in the population.”

The paper indicated that Brassard's team expects that eradicating this bacterium could prevent about 200,000 Alzheimer's cases worldwide each year.
