Alzheimer's disease: current and future therapeutic perspectives.

1. A better understanding of the pathophysiology of AD has been made possible through population-based epidemiological studies, human genetic and post-mortem studies, leading to a number of testable hypothesis towards delaying progression. 2. A number of disease milestones have been identified as therapeutic targets, such as conversion from MCI to diagnosable dementia. 3. Clinicians caring for patients with AD have currently available a number of symptomatic drugs, and will have in the future the ability to predict the risk for asymptomatic individuals to develop AD, and provide advice towards prevention.
