Numerous studies have demonstrated the significance of a variety of oral microorganisms, especially bacteria, in relation to general health. According to recent studies, depression may be associated with a lack of diversity in the bacteria that live in your mouth. Prolonged emotions of melancholy, hopelessness, and disinterest in activities are hallmarks of depression, a complicated mental health illness.
According to the most recent study, depression is linked to a lesser diversity of oral bacteria, according to researchers at NYU Rory Meyers college of Nursing. A wide variety of microorganisms, such as bacteria, viruses, and fungi, can be found in the mouth. These microbes are essential to both general health and dental health.
Bei Wu, the study's senior author and vice dean for research at NYU Rory Meyers college of Nursing, stated in an official statement that "a deeper comprehension of the relationship between the oral microbiome and depression could not only help us learn about the mechanisms underlying depression but could contribute to the development of new biomarkers or treatments for mood disorders."
The BMC Oral health journal has published the findings.
The study was carried out by the Centers for Disease Control and Prevention using survey and biological data from the National health and Nutrition Examination survey (NHANES).
The researchers used data from over 15,000 US participants who were 18 years of age or older to analyze questionnaires that examined symptoms of depression using saliva samples. Samples were gathered from 2009 to 2012.
The researchers discovered that people who had less diversity in their oral microbiomes were more prone to have depressive symptoms. Dental care, alcohol consumption, and smoking can alter the composition of oral microorganisms.
The oral microbiota may affect depression symptoms by altering the immune system or causing inflammation. On the other hand, depression can lead to changes in oral microbiota, such as poor dental hygiene, increased smoking and drinking, food changes, or pharmaceutical use, Wu said.
"More investigation is required to determine the course and underlying mechanisms of this association. "This work is part of a larger effort to understand how the oral microbiome influences cognitive decline and the onset of dementia, in addition to mental health," she said.
