UCLA images CTE in retired NFL players; Aspirin doubles risk of AMD

(January 27, 2013 - Insidermedicine)

From California - A new report published in the American Journal of Geriatric Psychiatry is the first to use imaging to document concussion-related brain damage in retired NFL players. Researchers studied 5 retired NFL players, aged 45 or older, all of whom had a history of concussions and were experiencing mood or cognitive problems. Participants received injections of a chemical marker called FDDNP that binds to amyloid beta plaques and tau tangles, and then underwent PET scanning. A group of healthy men were also examined. Results showed that the NFL players had much higher levels of FDDNP than the healthy men, and that those who had reported the most concussions had the highest levels of FDDNP




From Australia – Regular aspirin use may increase risk of age-related macular degeneration, according to a report published in JAMA Internal Medicine. Researchers studied over 2,300 individuals for 15 years. Just over 10% of participants were regular aspirin users.  Results showed that the cumulative incidence of AMD for regular aspirin users was 2% at 5 years, 7% at 10 years, and 9% at 15 years. The cumulative incidence for non-users, by comparison, was .8% at 5 years, nearly 2% at 10 years and 4% at 15 years.
