Research results have been published showing that Helicobacter pylori, which is considered the main cause of gastritis and stomach cancer in Koreans, can travel to the brain and cause Alzheimer’s disease. [사진=게티이미지뱅크]Helicobacter pylori (H. pylori), which is estimated to be present in nearly half of the world’s population, is a type of bacteria that lives in the sticky mucus surrounding the stomach. It can spread from person to person through raw food or water contaminated with bacteria.
Among the eating habits of Koreans, the habit of eating stews and soups together can transmit Helicobacter pylori bacteria to each other. Although in most cases it does not cause serious health problems, about 15% of people may develop ulcers in the lining of the stomach or duodenum.
Among these, research results were published showing that the bacteria can travel to the brain and cause Alzheimer’s disease. A study published in the journal Alzheimer’s & Dementia found that people who experienced symptoms of H. pylori infection were 11 percent more likely to develop Alzheimer’s disease, the most common form of dementia.
Researchers at McGill University in Canada analyzed the health data of more than 4 million people aged 50 or older between 1988 and 2019, and found that the risk of developing brain disease was highest 7 to 10 years after being infected with bacteria, and that patients with gastrointestinal diseases caused by infection had a higher risk of Alzheimer’s disease. were 24% more likely to suffer from
The researchers said, “We cannot prove that Helicobacter pylori infection is a definite cause of the increased risk of Alzheimer’s,” but explained, “The bacteria can travel to the brain, causing inflammation and loss of brain cells.”
The researchers said, “H. “Pylori can disrupt the blood-brain barrier via the oral-nasal-olfactory axis or through infected circulating monocytes, potentially leading to neuroinflammation, neuronal damage and neurodegeneration,” he added.
The researchers also said, “Bacteria can also disrupt the intestinal microbial community, causing overproduction of amyloid, a sticky protein present in the brains of Alzheimer’s patients,” and added, “Intestinal damage caused by chronic Helicobacter pylori infection can result in loss of vitamin B12 and iron. “It can affect absorption, which has been linked to dementia.”
Researchers estimated that eradicating Helicobacter pylori could prevent approximately 200,000 cases of Alzheimer’s disease each year worldwide.
