Researchers have identified a potential link between microbes in the throat and schizophrenia. This link may offer a way to identify causes and develop treatments of the disease and lead to new diagnostic tests. Recent studies have shown that microbiomes-the communities of microbes living within our bodies can affect the immune system and may be connected to mental health. Research linking immune disorders and schizophrenia has also been published, and this study furthers the possibility that shifts in oral communities are associated with schizophrenia. The study helps to identify possible contributing factors to schizophrenia. With additional studies, researchers may be able to determine if microbiome changes are a contributing factor to schizophrenia, are a result of schizophrenia or do not have a connection to the disorder.
