‘Superagers’ over 80 have the memory and brain connectivity of twenty-somethings
Both the default mode network and salience network in superagers had stronger connectivity than typical older adults and similar connectivity as younger adults. Superagers performed similarly to young adults and better than typical older adults in recognition and episodic memory tasks. ... Read More...
Depression may be a new biomarker for Alzheimer’s in older people
In healthy older adults, depression and cortical amyloid may be associated with early changes in cognition. The findings provide an additional biomarker for Alzheimer's disease. ... Read More...
