Today, approximately 10% of the world's population is over the age of 60; 
by 2050 this proportion will have more than doubled.  Moreover, the 
greatest rate of increase is amongst the "oldest old," people aged 85 and 
over.  While many older adults remain healthy and productive, overall this 
segment of the population is subject to physical and cognitive impairment 
at higher rates than younger people.  In this talk, I will survey new 
technologies that incorporate Artificial Intelligence techniques to support 
older adults and help them cope with the changes of aging, in particular 
with cognitive decline.  My focus will be on the use of automated planning, 
reasoning under uncertainty, and machine learning in systems that support 
extended autonomy, and I will use the Autominder cognitive orthotic system 
as an example of this type of system.
