the medical records of 3,500 men and women

Pessimistic, anxious and depressed people may have a higher risk of dementia, US researchers reported on Thursday. A study of a group of 3,500 people showed that those who scored high for pessimism on a standardized personality test had a 30 percent increased risk of developing dementia 30 to 40 years later. Those scoring very high on both anxiety and pessimism scales had a 40 percent higher risk, the study showed. "There appears to be a dose-response pattern, ie, the higher the scores, the higher the risk of dementia," Dr. Yonas Geda, a neuropsychiatrist at the Mayo Clinic in Rochester, Minnesota who led the study, said in a statement. Geda and colleagues looked at the medical records of 3,500 men and women who lived near the clinic between 1962 and 1965.
美國研究人員周四公布的一份研究報告顯示，悲觀、憂慮和情緒低落的人更容易患老年癡呆等病癥。 研究對3500人進(jìn)行了調(diào)查，調(diào)查發(fā)現(xiàn)，那些在個性測試中悲觀表現(xiàn)得分高的人在30年至40年之后出現(xiàn)癡呆的風(fēng)險較之其他人要高出30％。那些同時具有憂 郁和悲觀性格的人，其以后發(fā)生癡呆的風(fēng)險也更大，要比常人高出40％。 “這就像是劑量效應(yīng)，也就是說，得分越高，患老年癡呆的風(fēng)險越高。”美國明尼蘇達(dá)州梅約醫(yī)學(xué)中心的神經(jīng)精神病學(xué)家約納斯?格達(dá)如是說道。格達(dá)醫(yī)生是這次研究的負(fù)責(zé)人。他于他的同事們查看了3500名該中心附近的居民從1962年至1965年間的醫(yī)療記錄。
