Alzheimer’s disease (AD) is a common disease in the United States with almost 10% of people older than 65 suffering from the disease. A few drugs provide some improvement in mental function in mild-to-moderate disease, but no treatments are available to prevent the development of AD. Two new classes of drugs being investigated for the treatment or prevention of AD include drugs to decrease beta amyloid accumulation and Tau protein aggregation inhibitors. After disappointing results for treatment of AD, both classes are being tested in prevention trials.
