Depression May Not Be Caused by Chemical Imbalance – Mercola

According to the original article referenced below, it is a long held and widespread belief that depression is the result of a chemical imbalance that occurs in the brain. This theory has been popularized and spread by pharmaceutical companies and psychiatrists despite a lack of evidence to support it.

  • Today, the rate at which physicians and psychiatrists accepted that theory is alarming. This is because it aligned with their beliefs about other bodily functions.
