We know narcolepsy with cataplexy, which has a very clear cause-- you know, it's a deficit in orexin, and so forth.

我们知道伴有猝倒症的发作性睡病有一个非常明确的原因——你知道，这是食欲素缺乏等。

Type 1 is usually based on having low levels of hypocretin, a brain hormone that regulates sleep, or a person reporting cataplexy.

1 型通常是基于低水平的伪君子，一种调节睡眠的大脑激素， 或报告有猝倒症的人。

Whether a person has cataplexy associated with their narcolepsy or not is the main determinant of the type of narcolepsy that they have.

一个人是否患有与发作性睡病相关的猝倒症是他们所患发作性睡病类型的主要决定因素。

There are two main types of narcolepsy: Type 1, which was previously termed narcolepsy with cataplexy, and Type 2, previously called narcolepsy without cataplexy.

发作性睡病有两种主要类型：1 型，以前称为发作性睡病伴猝倒， 以及 2 型， 以前称为无猝倒性发作。
