You might think that antidepressants  are only for your brain.

00:02

After all, people take them for brain stuff.

00:05

Depression, anxiety, OCD, and so on. But there’s research to  suggest that antidepressants may be able to help with stuff all over the body.

00:13

Stuff like cancer. Yes, really. We do not clickbait around here.

00:18

Here’s how this would work and how it could start helping people soon.

[♪INTRO]

00:25

There are several different  types of antidepressants, and they work by adjusting the balance of neurotransmitters in the brain.

00:31

Each of the medication types  might have different side effects, and people might respond better to  one antidepressant over another, even within the same class.

00:39

For today, we’re just going  to talk about two main types: MAOIs and SSRIs.

00:43

MAOIs were the first  antidepressants on the market.

00:46

The acronym is short for  monoamine oxidase inhibitors, and as the name suggests, it works by blocking an enzyme called monoamine oxidase.

00:54

The usual function of monoamine  oxidase is to break down neurotransmitters in your brain,  like serotonin and dopamine.

01:01

While every neurotransmitter is complicated, these two very generally are  involved in helping you feel good, so you might think “hang on, I need those.” But breaking down of it is an  important part of maintaining balance and making sure you don’t  get too much of a good thing.

01:16

But sometimes, you don’t have  enough of the good thing, and monoamine oxidase is slashing too many of your feel-good chemicals.

01:22

That’s where the inhibitor in MAOI comes in.

01:25

The MAOIs basically say, “Good  job, enzyme, but that’s enough for now.
