People who have had a stroke may be at increased risk of developing Alzheimer's Disease, according to a new study in the December issue of Neurology. Researchers analyzed data from more than 1,700 Medicare patients. And they found the annual incidence for Alzheimer's was higher if the person had cardiovascular disease and even more so if the person had a stroke. Researchers say that the association between stroke and Alzheimer's may have to do with the effects of stroke and the vascular disease process. The study was conducted by researchers at Columbia University in New York.
The company that brought Flumist to noses nationwide is investigating future intranasal vaccines that could help prevent serious childhood illnesses. Medimmune has done pre-clinical testing on a vaccine that would battle Respiratory Syncytial Virus, Parainfluenza Virus Type 3 and Human Metapneumovirus. Early results indicate all three may be combined into one intranasal vaccine. Medimmune is still testing the safety of the potential vaccine, and will conduct human studies next year if results remain positive
