Alzheimer’s disease is a debilitating neurodegenerative disease characterized by dementia and memory loss. It is the sixth leading cause of death in the United States, where more than 5 million people are affected. Globally there are an estimated 36 million people who suffer from dementia including Alzheimer’s disease, a number that is projected to double every 20 years. There is clearly a need for more effective therapies that address this and other neurodegenerative diseases; however, the R&D efforts put forth by pharmaceutical companies have rarely been successful, as illustrated by the recent failure of the Alzheimer’s drug bapineuzumab in clinical trials.
