阿爾茨海默病是一種腦部疾病,會導致記憶、思維和行為方面的問題。

大多數老年癡呆癥患者年齡在65歲及以上。它被認為是老年人中最常見的精神疾病,而且患者的數量正在增加。目前,還沒有治愈阿爾茨海默氏癥的方法,但科學家們正在研究改善這種疾病患者生活質量的方法。Listentotheconversationandnumberthepicturesinthecorrectorder.712345Kenneth,aNewYorkstudent,inventedaspecialproductforAlzheimer'spatientsinspiredbyhisgrandfather'scondition.Oncehisgrandfathergotlostforawholeday.Worriedabouthisgrandfather'ssafety,Kennethsoughtasolution.Onenight,watchinghisgrandfathergetoutofbed,hehituponanidea:apressure-sensingdeviceinsocks.Hesketchedhisidea,figuredoutthepoweringmethod,andcreatedacoin-sizeddevice.Whenwornbyhisgrandfather,thesockssentanalarmtoKenneth'sphoneuponsensingpressure,allowinghimtoknowhisgrandfatherwasupwithoutstayingawakeallnight.Thus,thesocksthateasilyfindthesickwereinvented.Rewritethestoryaccordingthecorrectorderoftheconversation!12345Listentotheconversationandnumberthepicturesinthecorrectorder.7

紐約的學生肯尼斯受他祖父的病情啟發,發明了一種針對老年癡呆癥患者的特殊產品。有一次,他的祖父迷路了一整天。由于擔心祖父的安全,肯尼斯尋求解決辦法。一天晚上,看著爺爺下了床,他突然想到了一個主意:在襪子里裝一個壓力感應裝置。他勾勒出他的想法,找出了供電方法,并創造了一個硬幣大小的裝置。當他的祖父穿上襪子時,肯尼斯的手機會感應到壓力,發出警報,讓他知道他的祖父已經醒了,而不用整夜不睡去看護。因此,發明了容易找到病人的襪子。Listentotheconversationandnumberthepicturesinthecorrectorder.apairofsocksdesignedforpeople
