媒体英语 Art may reveal early signs of dementia 艺术作品可显示失智症前兆

Play audio file 文字稿 我们能否从艺术作品中发现失智症以及其它退化性疾病的迹象？研究人员详尽分析了多名曾患神经疾病的艺术家的作画笔法。从一系列有趣的线索中可以看出，在艺术家们表现出明显的症状之前，其脑部就已经产生了变化。科学家对这些作品进行了“分形分析”，这种数学方法探讨的是在数学界和自然界中反复出现的固定模式。请听 Dominic Hughes 的报道。

Researchers use a complex method called 'fractal analysis' as a way of looking at recurring patterns in both maths and in nature. They include the recurring patterns of our brainwaves and heartbeats as well as the brushstrokes of artists, which are as distinct as individual handwriting.

A psychologist, Alex Forsythe from the University of Liverpool, carried out a fractal analysis of more than two thousand works by seven famous artists. Among those who developed dementia or Parkinson's disease, such as Willem de Kooning and Salvador Dali, there was a significant change in the tiny patterns left by their brushstrokes decades before any obvious symptoms.

But for artists such as Picasso or Monet, who both died without developing any known neurological disorders, there was no alteration, regardless of style or subject matter.
