DATA SOURCES： Using the terms ＂Alzheimer disease, etiology, drug treatment＂, we searched Medline database for AD treatment-related English literatures which were published between January 1993 and September 2006. Other literatures were obtained by searching concrete magazines and papers by hand. STUDY SELECTION： The data were selected primarily. Epidemiologic study and randomized controlled clinical trials were selected, and those studies with repetitive or similar contents were excluded. DATA EXTRACTION： Totally 1 537 AD and its treatment-related literatures were collected, and 32 of them were involved. Altogether 1 505 non-randomized controlled clinical trials, repetitive studies and reviews were excluded. DATA SYNTHESIS： The restriction of curative effect is a progressive neural degenerative disease. Although the etiological hypothesis of this disease has been introduced, the etiological factors of this disease are still unclear. The current treatments mainly involve： preventing against A 13 formation and clearing A 13, application of antioxidant and free radical scavengers, application of anti-inflammatory preparation, application of cholinergic preparation, hormonal therapy, application of metabolic enhancer, application of neurotrophic factor and nerve protectant, gene therapy and so on. CONCLUSION： The etiological factors of AD are still unclear, and symptomatic treatment is much taken in clinical therapy. Therefore, the curative effects of AD are still not very ideal.展开更多
