The messages doctors give can influence some treatments' effectiveness.
肌肉放松治療師的按摩治療能對一些疾病的治療帶來效果。
For example, it seems that information from a doctor affects outcomes for migraine sufferers—whether they got a real drug or a placebo.
比如，醫(yī)生給予的意見可以影響偏頭痛患者的治療結果—無論他們是服用了真的藥物還是安慰劑。
Researchers studied 66 people with recurring migraines over the course of seven attacks.
研究人員們對66名多發(fā)性偏頭痛患者經歷的7次病痛期及期間進行的相應治療進行了詳細的研究。
During the first headache, the patients received no treatment.
在第1次頭痛期間，病人沒有進行任何治療。
For the next six, they were given either a placebo or a drug.
而在接下來的6次當中，他們要么接受安慰劑治療，要么就是真的藥物。
Each time, regardless of which they got, some were told it was the drug, some were told it was the placebo, and the rest were informed that it could be either the drug or the placebo.
不管每次接受什么樣的藥物治療，其中一些人被告知是藥物，另一些人則被告知是安慰劑，剩下的人則被告知2種都有可能。
Overall, the drug did work better than the placebo.
整體結果顯示，藥物的治療效果比安慰劑更好。
But the placebo worked, too—both when the patients were told it was a placebo, and even better when the doctors told them that they were getting the drug.
但是，安慰劑也有一定的藥效—那就是當病人被告知他們被給予安慰劑的時候，醫(yī)生告訴患者他們正在接受藥物治療后，安慰劑的療效甚至更好。
That is, when the docs set their expectations high.
這就說明醫(yī)生的話提高了患者的期望值。
Meanwhile, the actual drug was least effective when the patients thought it was a placebo.
同時，在患者認為自己得到的是安慰劑時實際療效則是最低的。
The study is in the journal Science Translational Medicine.
該研究已在《科學轉化醫(yī)學》雜志上發(fā)表。
The physician's input thus plays a role in how migraine patients fare.
內科醫(yī)生的意識灌輸直接被作用到偏頭痛患者攝入的物質中。
Tell them they're getting a good treatment, and they're apparently more likely to respond.
告訴他們正在進行一項很有用的治療，于是患者們就很明顯的更愿意給予積極的響應了。
