Depression is the leading cause of disability worldwide.

抑鬱症是導致全球殘疾的主要原因。

And millions of people have something known as treatment resistant depression, meaning they have failed at least one oral antidepressant.

數百萬人患有所謂的 "抗藥性抑鬱症"，這意味著他們至少有一種口服抗抑鬱藥無效。

and end up in emergency settings where physicians have started to have success using large magnets known as transcranial magnetic stimulation to pulse a person's brain, change their circuitry, and in real time decrease these depressive episodes.

在急診室裡，醫生們開始成功地使用被稱為經顱磁刺激的大型磁鐵對患者的大腦進行脈衝刺激，改變他們的電路，從而實時減少抑鬱發作。

The reason this works is because our brain and nervous system is actually an electrical system.

這樣做的原因是，我們的大腦和神經系統實際上是一個電氣系統。

Faraday's law states that if you pulse a magnet, you can generate a current in electrically conductive substances like the brain.

法拉第定律指出，如果給磁鐵脈衝，就能在大腦等導電物質中產生電流。

Since your hair and skull are not electrically conductive, this is why the magnet can get put on the outside of your head.

由於頭髮和頭骨不導電，這就是為什麼磁鐵可以放在頭部外側的原因。

and actually change the brain past the hair and skull. new scientific breakthroughs in the technology make it so the magnets can target very specific regions of the brain.

這項技術在科學上取得的新突破使磁鐵可以瞄準大腦的特定區域。

In the brains of people having a depressive episode, the subgenual anterior cingulate is overactive, and another region known as the left dorsolateral prefrontal cortex, it is down regulated or has lower activity in people who are depressed.

在抑鬱症患者的大腦中，前扣帶回下部過度活躍，而另一個被稱為左側背外側前額葉皮層的區域在抑鬱症患者中則受到抑制或活性降低。

The magnet is then targeted to a region like for example, the left dorsolateral prefrontal cortex.

然後將磁鐵定向到一個區域，例如左側背外側前額葉皮層。

and pulses in order to activate and increase synaptic currents within this brain region.

和脈衝，以激活和增加該腦區的突觸電流。

It increases activity and increases growth in the brain and decreases the symptoms of depression.

它能增加大腦的活動和生長，減輕抑鬱症狀。

What's also so fascinating if you take the dorsolateral prefrontal cortex, it actually grows in people who are experiencing psychotherapy.

同樣令人著迷的是，如果你觀察背外側前額葉皮層，它實際上會在接受心理治療的人群中生長。

So they study the brains of people going through psychotherapy and over long periods of time that part of the brain actually has more activity and increases in size, but these magnets are changing the brain quickly and in some cases in 2.6 days.

是以，他們對接受心理治療的人的大腦進行了研究，在很長一段時間內，大腦的這一部分實際上會有更多的活動，體積也會增大，但這些磁鐵能迅速改變大腦，在某些情況下，只需 2.6 天。

The concept of transcranial magnetic stimulation has technically been around since the mid nineties, but only FDA approved in 2008.

從技術上講，經顱磁刺激的概念早在上世紀 90 年代中期就已出現，但直到 2008 年才獲得美國食品及藥物管理局的準許。

Known as Saint, Stanford accelerated intelligent neuromodulation therapy, this new type of transcranial magnetic stimulation happens much faster.

這種新型經顱磁刺激療法被稱為 "聖"，即斯坦福加速智能神經調控療法，其治療速度更快。

This is a fascinating growing field of research to me, but these therapies don't work for everyone and specific people will benefit more than others.

對我來說，這是一個令人著迷的不斷髮展的研究領域，但這些療法並非對所有人都有效，特定的人會比其他人受益更多。

Studies show it works better in people who have higher brain connections between the subgenual anterior cingulate and the dorsolateral prefrontal cortex, it's meant for people with severe depression who again have failed at least one oral antidepressant.

研究表明，它對那些大腦中前扣帶回下部和前額葉皮層背外側之間的連接較多的人效果更好，它適用於至少一種口服抗抑鬱藥無效的嚴重抑鬱症患者。

and due to its quick effects, it could be used more easily in hospital settings for people having severe depressive episodes.

而且由於它見效快，在醫院環境中更容易用於嚴重抑鬱發作的患者。

The reason I'm obsessed with this science.

When I first started learning about it, I was like, okay, what is going on here?

當我第一次瞭解它時，我就想，好吧，這到底是怎麼回事？

But as I've gotten to understand it more, I realized that this could be really groundbreaking and in the future we might all be getting used to magnets helping with depression.

但隨著我對它的瞭解越來越多，我意識到這可能真的具有開創性，將來我們可能都會用磁鐵來幫助治療抑鬱症。
