截至2010年底，台灣約有1/5的智能障礙者處於中高齡階段，這些智能障礙者的壽命雖因醫療、衛生的普及而得以延長，但是其生理機能卻往往面臨提早老化的現象，再加上這些智能障礙者大多與父母同住，因此有關照顧者與被照顧者雙重老化的議題便逐漸為人所重視。本文藉由文獻資料整理，探討智能障礙者雙老家庭在此生命階段中所承受的生理、心理與社會層面之壓力與挑戰，發現雙老家庭在生理層面所遇及的壓力包括健康預防的不易進行、生理退化的不可逆以及
疾病發生的比例偏高；於心理層面的承擔包括固有角色的轉換或喪失、不得不的分離面對以及擔憂不確定的未來；在社會層面所面臨的挑戰則包括華人文化無形的阻礙了正式資源的使用、正式支持系統的不足以及非正式支持系統的質變與量變。

Until the end of 2010, in Taiwan, there are 20% of mental retarded people living in their advanced age. Although the life spans of these mental retarded people are prolonged by the popularization of medical technology and sanitation, the physiological function and the vitality of them are prone to be aged early. Besides, owing to the fact that most of these mental retarded people are living with their parents, the importance of
the double-aging issue has also been raised. In light of this, through literary arrangement and review, this thesis will discuss the physiological, the psychological, and the social pressures and challenges these double-aging families faced in such a situation of their lives. Hence, it is discovered that the physiological pressures these double-aging families faced include the inaccessible health prevention, the irreversibility of physiological degeneration, and the high rate of disease occurrence; the psychology burdens these families carried include the change or the loss of their inherent roles, the necessary separation with their families, and the worry concerning the uncertain future; last but not the least, there are also many challenges coming from our society which include the obstructed use of official resources incurred by Chinese culture, the limited accessibility of official supporting system, as well as the qualitative and the quantitative
changes of the non-official supporting system.
