Bacteria in the Gut Could be Causing Anxiety!
Results from a new research show that gut bacteria influences brain behavior and chemistry. The study was conducted by a team of scientists at McMaster University.
According to Stephen Collins, one of the researchers, the results of this study indicate the possibility of the link between bacteria and behavioral illnesses.
The study was conducted on adult, healthy mice. When the normal gut bacterial count was disturbed through oral antibiotics, the mice became anxious and the levels of brain derived neurotrophic factor (BDNF), which is associated with anxiety and depression increased.
Gut bacterial count returned to normal when the usage of oral antibiotics was stopped. Moreover, normal brain chemistry and behavior were seen in the mice.
According to Collins, stability and nature of the gut bacteria may have an influence on the brain behavior.
Further investigation is needed on the potential of probiotic bacteria and their products to treat behavioral conditions, especially those associated with gastrointestinal tract such as irritable bowel syndrome.
