IU helps research Alzheimer's disease

CHICAGO -- Families with several members afflicted with Alzheimer's disease are being recruited for a new gene bank that might help speed new treatments or even prevention of the mind-robbing ailment.\nThe program was announced Tuesday by the Chicago-based Alzheimer's Association, which is working with the National Institute on Aging to create a gene bank with samples from more than 1,000 families affected by late-onset Alzheimer's. Most of the 4 million Americans with Alzheimer's have that form of the disease, which typically is diagnosed after age 60.\nWhile three genes have been linked to earlier-onset disease, researchers are less certain about the genetic causes of late-onset Alzheimer's.\n"By getting large samples like this, we should be able to start zeroing in on these genes," said Creighton Phelps, director of the NIA's Alzheimer's Disease Centers network. The network comprises 29 centers nationwide that will help collect blood samples for the gene bank.\nThe NIA is funding the initiative at a cost of about $2 million a year. It is expected to take about three years to identify patients and collect and analyze samples, Phelps said.\nWhile development of treatments might be years away, the large gene bank will greatly accelerate research efforts to identify Alzheimer-linked genes, which are hampered by having too few participants to draw major conclusions, said William Thies, medical director of the Alzheimer's Association.\n"It is such an important initiative and has so much potential," Thies said.\nMore than 100 families with more than two or three afflicted members already have been identified, Phelps said.\nThe Alzheimer's Association is helping with promotional efforts, which likely will include newspaper and magazine ads and mentions in newsletters published by the association's nationwide chapters, Thies said.\nParticipating families and afflicted members will have a single simple blood test and interview, which could be done by their own doctors in coordination with local Alzheimer Association chapters, Thies said.\nSamples will be sent to an NIA repository at the IU Medical Center in Indianapolis, where the research will be conducted.\nInterested families should contact local association chapters or check NIA and association Web sites at www.nia.nih.gov or www.alz.org.
