How Prozac sent the science of depression in the wrong direction

Like many other antidepressants, Prozac increases the brain's supply of serotonin, a neurotransmitter. The drug's effectiveness inspired an elegant theory, known as the chemical hypothesis: Sadness is simply a lack of chemical happiness.
There's only one problem with this theory of depression: it's almost certainly wrong, or at the very least woefully incomplete.
In recent years, scientists have developed a novel theory of what falters in the depressed brain. Instead of seeing the disease as the result of a chemical imbalance, these researchers argue that the brain's cells are shrinking and dying.
the drug works because it helps heal our neurons

In this sense, Prozac is simply a bottled version of other activities that have a similar effect, such as physical exercise. They aren't happy pills, but healing pills.

These discoveries are causing scientists to fundamentally reimagine depression.
