Myth: Doctors Know What Causes Depression
Truth: Experts haven’t fully sussed out why some people’s brains fall prey to depression. The most popular medications for the illness provide some clues, says Goldfine. Selective serotonin reuptake inhibitors (SSRIs) increase the amount of the feel-good neurotransmitter serotonin in your system.
Monoamine oxidase inhibitors (MAOIs) reduce the enzyme monoamine oxidase because it limits your levels of serotonin and other happy-making brain chemicals. “We’ve realized that if you increase or decrease certain chemicals, people tend to be in a better mood,” says Goldfine. “As for how it works or why it works, we’re still figuring that out.”
