Serotonin and Depression - The Big Lie

Drug companies claim that a "chemical imbalance" of serotonin in the brain causes depression and that the anti-depressant wonder drugs (like Zoloft, Prozac, Paxil, etc.) correct this imbalance. In truth there is NO evidence to back up these claims, which is why you will read "depression is a serious medical condition that may be due to a chemical imbalance." Note the word "may". The drug companies never say "is" they always say "may" or "it is believed" or "experts think". Hmmm, I always thought science was a field where you could say "is". Anyway, someone has recently taken a stand and told the truth: Serotonin and Depression: A Disconnect between the Advertisements and the Scientific Literature.
