Based on the studies carried out so far, the efficacy of aspirin, steroid and NSAIDs (traditional NSAIDs and COX-2 inhibitors) is not proven. Therefore, these drugs cannot be recommended for the treatment of AD.

Analysis 1.3. Comparison 1 Vitamin E (capsules 2000 IU/day in two divided doses) versus placebo in people with Alzheimer's disease, Outcome 3 Deaths (number of deaths over 48 months

Background Vitamin E is a dietary compound that functions as an antioxidant scavenging toxic free radicals. Evidence that free radicals may contribute to the pathological processes of cognitive impairment including Alzheimer's disease has led to interest in the use of vitamin E in the treatment of mild cognitive impairment (MCI) and Alzheimer's dementia (AD). Objectives To assess the efficacy of vitamin E in the treatment of AD and prevention of progression of MCI to dementia. Search methods The Specialized Register of the Cochrane Dementia and Cognitive Improvement Group (ALOIS), The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS as well as many trials databases and grey literature sources were searched on 25 June 2012 using the terms: "Vitamin E", vitamin-E, alpha-tocopherol. Selection criteria All unconfounded, double-blind, randomised trials in which treatment with vitamin E at any dose was compared with placebo for patients with AD and MCI. Data collection and analysis Two review authors independently applied the selection criteria and assessed study quality and extracted and analysed the data. For each outcome measure data were sought on every patient randomised. Where such data were not available an analysis of patients who completed treatment was conducted. It was not possible to pool data between studies owing to a lack of comparable outcome measure. Main results Only three studies met the inclusion criteria: two in an AD population and one in an MCI population. In the first of the AD studies (Sano 1996) the authors reported some benefit from vitamin E (2000 IU/day) with fewer participants reaching an end point of death, institutionalisation, change to a Clinical Dementia Rating (CDR) of three, or loss of two basic activities of daily living within two years. Of patients completing treatment, 58% (45/77) on vitamin E compared with 74% (58/78) on placebo reached one of the end 1 Vitamin E for Alzheimer's dementia and mild cognitive impairment (Review)
