Multicenter StudyCognition and amyloid load in Alzheimer disease imaged with florbetapir F 18(AV-45) positron emission tomography.
To examine the association between regional brain uptake of a novel amyloid positron emission tomography (PET) tracer florbetapir F 18 ([(18)F]-AV-45) and cognitive performance in a pilot study. ⋯ [(18)F]-AV-45 SUVR in several brain regions was associated with worse global cognitive performance particularly in HC, suggesting its potential as a marker of preclinical AD.

The course of subsyndromal delirium in older long-term care residents.
To determine the course of incident subsyndromal delirium (SSD) in older long-term care (LTC) residents. A secondary objective was to explore the use of a more restrictive definition of SSD on the findings of the study. ⋯ Episodes of SSD in older LTC residents appeared to last 7-133 days (mean: 13.7) and were often recurrent. Use of a more restrictive definition resulted in a more protracted course.
