Alzheimer's disease is the leading cause of dementia and currently affects more than seven million people in the United States. Gaps in Alzheimer's BiologyOne major obstacle to developing better therapies is that researchers still do not fully understand the biology behind Alzheimer's disease. The protein has been linked to Alzheimer's disease, but it has remained poorly understood partly because researchers have lacked suitable compounds for studying it. To find useful compounds, Schultz, Parr, and other WCNDD researchers created a large collection of related molecules. The compound could provide a starting point for research aimed at developing future Alzheimer's disease treatments.
