One of the things I explore in depth in Brain Maker is the notion that even depression is now considered an inflammatory disorder. We now understand that inflammatory markers, the same that we see elevated in heart disease are also elevated in the depressed patient. So the question is: If depression is an inflammatory disorder then where does the inflammation come from? Interestingly that is more or less the title of a study that was recently published in a British medical journal in 2013. In this video we take a closer look at the gut microbiome, leaky gut and how it relates to disorders such as depression.
