Alzheimer's disease (AD) is an incurable neurodegenerative disease and is the most common cause of dementia that affects elderly people (Izenberg, 2000). Today as citizens are living longer, AD is reaching epidemic proportions with no cure available (Tanzi and Bertram, 2005). In America, 4 million people are affected by this disease and it is estimated that the epidemic will jump 44 percent by the year of 2025 (Medline Plus, 2006). AD patients live debilitating lives of faulty memory, judgment, and reasoning (Tanzi and Bertram, 2005). However, a promising study published in Neuron by Simard et al. (2006) suggests a future therapeutic strategy. They employ stem cells that specifically target the amyloid deposits, the toxic culprit in this disease pathology.
