Frailty is a predictor of functional decline, falls, hospitalization, and mortality. Fried et al. developed the frailty index, which include 5 simple items: weight loss, weakness, exhaustion, slowness, and low activity. ⋯ Both frailty and sarcopenia could be associated with mild cognitive impairment which leads to dementia. Thus, early initiation of a comprehensive geriatric health examination and a multidomain intervention such as diet, exercise, cognitive training, and vascular risk monitoring may be useful to prevent frailty and sarcopenia in community-dwelling older adults.

Several promising tau imaging probes have been developed by Tohoku University ([18F]THK series), National Institute of Radiological Sciences([11C]PBB3), Eli Lilly ([18F]T807), and Hoffman-La Roche ([18F]R06958948). In this paper we discussed some of the criteria required for the tau imaging probe in Alzheimer's disease. It will be certain that tau imaging plays an important role in an accurate diagnosis and as companion diagnostics.
