英国的科学家们表示，一项简单的皮肤拭子检查可用来帮助诊断退化性大脑疾病帕金森病。对志愿者的研究表明，该检查能快速测出皮脂中显示患病迹象的化合物，皮脂是一种保护皮肤的油性物质。

 

There are an estimated 145,000 people living with Parkinson's in the UK, but there is no cure and no definitive¹ test for the disease.

据估计，英国约有14.5万人患有帕金森病，但目前没有治愈该病的方法，也没有能检测出该病的可靠手段。

 

The researchers say trials on 500 people showed a skin swab could correctly identify 85% of cases.

研究人员们说，对500人进行的试验表明，有一项皮肤拭子检查可以正确识别85%的病例。

 

Their new technique works by analysing compounds found in the sebum – the oily substance that coats the skin – and identifying changes in people with the disease.

他们的新技术依靠分析皮脂（包裹皮肤的油性物质）中的化合物，并识别它们在患者身上的变化来进行检测。

 

The team at the University of Manchester said this is the first step towards what could be a fast, painless and cheap form of diagnosis². It could also be used to track the progression of Parkinson's and to measure whether new experimental treatments are having an impact.

曼彻斯特大学的研究团队表示，这是实现快速、无痛、廉价诊断方式的第一步。这项技术还可以用来追踪帕金森病的病情变化，并检测新的实验性治疗是否有效。
