Research lead to the development of root treatment and prevention of Alzheimer's type dementia.

From this month , research group of the Ministry of Health, Labour and Welfare , embark on research lead to the development of root treatment and prevention of Alzheimer's type dementia .Conduct a survey of patients and families of familial Alzheimer's disease to develop almost certainly Alzheimer's type dementia . By joining " DIAN ( Diane ) " in the international a study of people with the gene for this disease , drug discovery and elucidation of the pathogenic mechanism of Alzheimer's disease is entirely expected .Elderly people with dementia across the country , about 4.62 million people in the estimate . There are several types of major dementia , Alzheimer's type of the primary symptoms most is memory loss , which accounts for about 70% of the total . According to the study overseas , almost all of the people with the gene for familial Alzheimer's disease onset , 40s , and 50s is greater time of onset . In the world , with the family genes have been found about 520 , but the actual situation in Japan is unclear .
First, I want go lead to development of therapeutic agents fundamental and prevention and to understand the actual situation .

厚生労働省の研究班は、今月から、アルツハイマー型認知症の予防や根本治療薬の開発につながる調査研究に乗り出す。
　アルツハイマー型認知症をほぼ確実に発症する家族性アルツハイマー病の患者や家族の実態調査を実施。この病気の遺伝子を持つ人を対象にした国際研究「ＤＩＡＮ(ダイアン)」に参加することで、アルツハイマー型認知症全体の発症メカニズムの解明や創薬が期待される。
　全国の認知症高齢者は、推計で約４６２万人。主な認知症には数種類あるが、記憶障害が主症状のアルツハイマー型が最も多く、全体の約７割を占める。海外の研究によれば、家族性アルツハイマー病の遺伝子を持つ人のほぼ全員が発症し、発症の時期も４０歳代、５０歳代などが多い。世界では、遺伝子を持つ家系は約５２０見つかっているが、日本での実態は不明だ。
　まずは実態を把握して予防や根本的な治療薬の開発につなげていって欲しいですね。
