PET shows education's benefit in Alzheimer's

June 4, 2013

PET images showed that highly educated individuals with mild cognitive impairment who later progressed to Alzheimer's disease coped better with the disease than individuals with a lower level of education, according to a study in the June issue of the Journal of Nuclear Medicine.

Specifically, PET illustrated how neural reserve and neural compensation both play a role in determining cognitive reserve. Cognitive reserve refers to the capacity of an adult brain to cope with brain damage and maintain a relatively preserved functional level.
