U.S. law requires that Diversity Immigrant visas be made available through a strictly random process. A computer programming error resulted in a selection that was not truly random. Each year, up to 55,000 people receive a green card through the lottery. A new draw will be conducted by July 15, 2011.

The new study included more than 300 patients in their seventies, 114 with normal memories, 200 with memory problems, and 102 with Alzheimer’s disease. Their spinal fluid was analyzed for amyloid beta, which forms plaques in the brain, and for tau, another protein that accumulates in dead and dying nerve cells in the brain. Nearly every person with Alzheimer’s had the characteristic spinal fluid protein levels. However, should doctors offer, or patients accept, commercially available spinal tap tests to find a disease that is, as yet, untreatable?
