For years, researchers have had to use tissue obtained posthumously to diagnose chronic traumatic encephalopathy, or C.T.E., the degenerative brain disease that has bedeviled athletes, soldiers and others who have sustained repeated head hits and concussions.
But a study published in The American Journal of Geriatric Psychiatry on Tuesday suggests that PET scans could one day be used to diagnose the disease in living patients.
Last year five retired N.F.L. players who were 45 years and older and suffered from mood swings, depression and cognitive problems were given PET, or positron emission tomography, scans. The authors of the study said those scans revealed tau protein deposits in their brains, a signature of C.T.E. While not definitive, the distribution of tau in the retired players was consistent with those found in the autopsies of players who had C.T.E...
The players in the study received intravenous injections of FDDNP, a chemical marker designed to bind to deposits of amyloid beta plaques and neurofibrillary tau tangles that are signs of Alzheimer’s disease. The FDDNP was then viewed on the PET scans, which were compared to those of healthy men of similar age, body mass, education and family history of dementia....
