According to a study published in the journal Nature Communications<\/b>, Chlamydia pneumoniae<\/i>\u2014a bacterium typically responsible for pneumonia and sinusitis\u2014may persist in the human eye and brain for years, significantly accelerating the development of Alzheimer\u2019s disease<\/b>.<\/p>\n
The study reveals that this bacterium reaches the retina, where it triggers an immune response and chronic inflammation. Researchers explain that the eye acts as a physical extension of the brain. Therefore, detecting bacterial infection and inflammation in the retina allows scientists to predict pathological processes occurring in the brain through non-invasive<\/b> methods, such as eye scans.<\/p>\n
By conducting an in-depth analysis of tissues from 104 individuals<\/b>, scientists identified a direct link between bacterial infection and neurodegeneration:<\/p>\n Concentrations of Chlamydia pneumoniae<\/i> were significantly higher in the retina and brain of Alzheimer\u2019s patients.<\/p>\n<\/li>\n The increase in bacterial load correlates proportionally with the severity of cognitive decline<\/b>.<\/p>\n<\/li>\n<\/ul>\n The research also highlights a significant genetic component. High levels of infection are particularly prevalent in individuals carrying the APOE4 gene<\/b>, suggesting that this gene plays a role in the body\u2019s vulnerability to the bacterium.<\/p>\n Furthermore, the infection was found to provoke the accumulation of amyloid-beta<\/b>, a pathological protein that accelerates the death of nerve cells in the brain.<\/p>\n This discovery opens entirely new possibilities for intervention. Scientists suggest that by targeting these factors\u2014using early antibiotic therapy<\/b> and anti-inflammatory treatments\u2014it may become possible to delay the progression of the disease.<\/p>\n\n
