«Because Candida is a natural component of the
human body
microbiome, yeast overgrowth or infection in the digestive tract, for example, may
disrupt the gut - brain axis.
We are doing things that are
disrupting them,» said Dr. Martin Blaser, director of the
Human Microbiome Program at New York University Langone Medical Center.
The delicate balance between the
human microbiome and the development of psychopathologies is particularly interesting given the ease with which the
microbiome can be altered by external factors, such as diet, 23 exposure to antimicrobials24, 25 or
disrupted sleep patterns.26 For example, a link between antibiotic exposure and altered brain function is well evidenced by the psychiatric side - effects of antibiotics, which range from anxiety and panic to major depression, psychosis and delirium.1 A recent large population study reported that treatment with a single antibiotic course was associated with an increased risk for depression and anxiety, rising with multiple exposures.27 Bercik et al. 28 showed that oral administration of non-absorbable antimicrobials transiently altered the composition of the gut microbiota in adult mice and increased exploratory behaviour and hippocampal expression of brain - derived neurotrophic factor (BDNF), while intraperitoneal administration had no effect on behaviour.
