Screening for Alzheimer's May Become Cheaper

Finding a cure for Alzheimer's is an extremely complex task. Scientists still do not know what causes the disease. Once the symptoms appear, the gradual memory loss is inevitable and available drugs can only slow down the process. Researchers, however, believe the disease develops slowly, over years, so detecting it before the symptoms appear may give the patients a better chance of a longer life. VOA's George Putic reports.
