Someone who can't sleep is called an insomniac.

无法睡着的人被称为失眠症患。

An insomniac is someone who can't sleep easily.

失眠症患是指无法轻易入睡的人。

Really tired insomniacs who can't focus get up at 4 a.m. too.

凌晨4点起床的也可能是真的很累的失眠症患。

So does this chatty insomniac have a name?

哦 这个健谈的失眠症患叫什啊？

If you're an insomniac – someone who can't sleep easily – it's tempting to open up your laptop and start shopping.

如果你是失眠症患——一个很难入睡的人——开你的笔记本电脑开始购物是很有诱惑力的。

While that happens to everyone every once in awhile, people with insomnia have to deal with these symptoms night after night.

可能每个人都有过这样的一段时间，而患有失眠症的患需要一晚一晚地抵抗这些症状。

So, I think it will really lead to a complete redefinition of the diagnosis of people who have idiopathic hypersomnia or insomnia.

因此，我认为这将真正导致对特发性嗜睡症或失眠症患的诊断进行彻底的重新定义。

Another condition is called fatal familial insomnia, where patients have symptoms such as progressive insomnia, weight loss, extreme body temperatures, and rapidly progressing dementia.

Blocko：另一种情况称为致死性家族性失眠症，患会出现进行性失眠、体重减轻、体温过高和快速进展性痴呆等症状。

And the evidence is in the professional literature, in books and journal papers, etc. And if you're an insomniac, you're welcome to look at all that.

证据在专业文献 书籍和期刊论文中 等等 如果你是失眠症患 你可以看看这些。

While most insomniacs somehow manage to drag themselves through the day and function at acceptable, although not optimal levels, --- this is not so for people who suffer from hypersomnia.

虽然大多数失眠症患设法以某种方式勉强自己度过一天并在可接受的水平上工作，尽管不是最佳水平，但对于患有嗜睡症的人来说并非如此。
