人們常說：夕陽無限好，只是近黃昏。生命，從出生到結束，這是一個歷程，有其美麗與哀愁！不管智或愚都會有生、老、病、死的現象要承受。而老化，正是自然的生理變化過程。由於科技的發達，生活品質提升，人的壽命延長，智障者也不例外。對於高齡智障老者的安置照護服務的研究刻不容緩。此研究分析智障者老化引發的家庭照顧人力、生活問題，並進一步探討高齡智障者的照護服務需求，尋求可能的安置選擇方式以及政策因應之道。亦藉由過去專家學者的研究成果瞭解智障者老化特質與家庭照顧工作的問題，察覺未來智障者照護體系存在的問題，為未來可能面對的困境，尋找福利服務與政策可能發展的方向。好讓我們提高對智障老化現象的警覺性，提早規劃醫療與高齡智障照護服務體系相對應的措施，並衡量運用一般老人福利服務的可能性，最後，智障福利服務應確切的加以落實，且在此領域中，政府應扮演主動性的角色，提供每一個智障家庭足夠的福利資源。希望以上探討的結果，能提供政府或民間在建立智障老者的照護規劃之正面建議；更盼可以拋磚引玉喚起社會大眾的愛心，對智障老者的關懷照護貢獻自己的心力。
