Researchers from the Northwestern University Feinberg School of Medicine shared two major findings:
1. Antidepressant drugs were not developed for depression. Researchers used certain drugs to manipulate the behavior of stressed animals, and then concluded (erroneously) that the drugs would be “good antidepressants.” But chronic stress does not cause the same molecular changes that depression does, making the hypothesis incorrect.
So, antidepressants were actually designed to treat stress, rather than depression — which is one reason they are so ineffective.
2. An imbalance of neurotransmitters in your brain may not trigger depressive symptoms as has long been thought. Instead, the biochemical events that lead to depression appear to start in the development and functioning of neurons. This means antidepressants focus on the effect of depression and completely miss the cause… yet another reason why they are so ineffective for most people.
Unfortunately, the lead researcher is hoping the research will “open up new routes to develop new antidepressants,” when in reality a drug solution is not the answer.
