Alzheimer’s Disease :: Clinical Diagnosis of Alzheimer?s Disease
In a study of people with mild cognitive impairment (MCI), those who took the drug donepezil were at reduced risk of progressing to a diagnosis of Alzheimer?s disease (AD) during the first year of the trial, but by the end of the 3-year study there was no benefit from the drug. Vitamin E was also tested in the study and was found to have no effect at any time point in the study when compared with placebo.
