"But it is a useful marker with amyloid imaging. We still don't know why some people with a head full of amyloid develop AD symptoms and others don't, and we may not for years to come," she said. "This may give us a new marker to see who is at greater risk for cogn...
A Positive Amyloid PET Scan Identifies Subtle Cognitive Problems in Asymptomatic Adults"I hope these compelling findings will motivate more of my basic science colleagues to start investigating klotho, its protein network partners, and its potential interactions with APOE," said Dr. Greicius. In ...

Background: Studies have showed that B-amyloid plaques are likely to only exhibit local affects on the cortex at early stages of the disease before or when early cognition impairments occur. Understanding when and where neurodegeneration starts in the cortex may provide insights into the pathogenesis...
bearing mice (n = 3) received [131I]-2Rs15d (32.37 ± 1.83 MBq; 5 µg sdAb; weekly on D7-14), identical to the treatment group, after which µSPECT/CT imaging was performed after 2 h using a rat PET-collimator and a spiral scan mode of 94 bed positions (19 s per position...
All had positive amyloid imaging with PIB PET scanning. Diagnosis was assessed annually in our JGH/McGill Memory Clinic with demographics, the MoCA (Montreal Cognitive Assessment), and genetic Apo E studies. Results The 30 progressors went on to AD dementia after a mean 3.1 years since their ...
We prospectively recruited 29 amyloid-positive ADCI patients, 28 amyloid-negative SVCI patients that were confirmed by 11 C-PiB-PET scan and 34 individuals with normal cognition (NC). The three groups were compared in terms of retinal vascular variables (retinal fractal dimension, vascular caliber,...
