What is the fattiest organ in the human body?

人體內含脂量最高的器官是?

Is it the skin, the brain, the liver, or the stomach?

是皮膚、大腦、肝臟還是胃?

The human brain is almost 60 percent fat, making it the fattiest organ we have.

人類的大腦大約有60%的脂肪，這使它成為我們最肥胖的器官。

AZUZ: There’s a new study out that suggests concussions and even more serious brain injuries might carry an increased risk of developing Parkinson’s disease later in life. This disorder has symptoms like shaking uncontrollably, trouble keeping balance and slow movements. And there’s no cure for it.

有一項新的研究表明腦震蕩和更嚴重的腦損傷可能會增加日后患帕金森癥的風險。帕金森癥的癥狀，比如無法控制的抖動、保持平衡和動作遲緩。而且沒有治愈的方法。

The study looked at the medical records of more than 300,000 military veterans. Now, its’ important to point out that relatively few of these people, less than 1 percent, ever developed Parkinson’s disease, even though half the veterans in the study had had some form of brain injury.

這項研究查看了30多萬退伍軍人的醫(yī)療記錄?，F(xiàn)在，需要指出的是，盡管有一半的退伍軍人患有某種形式的腦損傷,但這些人中只有不到1%的人患上了帕金森癥。

But among the nearly 1,500 who did develop Parkinson’s, almost 950 had had a traumatic brain injury, while just over 500 had not.

但在近1500名帕金森患者中，幾乎有950人腦部受傷，而只有500人沒有。

Researchers concluded that brain injuries carried a greater risk of developing Parkinson’s later on, at least among those who actually got the disease.

究人員得出結論，腦損傷后患帕金森癥的風險更大，至少在那些真正患有此病的人當中。

It’s one example of how scientists are constantly exploring the brain for symptoms of injuries that could lead to earlier diagnosis and maybe even a cure for brain diseases.

這是科學家們不斷探索大腦損傷的一個例子，這些癥狀可能會導致診斷及時，甚至可能治愈腦部疾病。
