Health Medical Homework Help

I’m studying for my Health & Medical class and need an explanation.

A. Using unique examples, explain what happens to humans’ fluid and crystallized processing as the brain ages. What role does neural distinctiveness play in each?

B. How does Thad Polk’s larger argument about memory as “transforming” with age rather than deteriorating, relate to Elizabeth Loftus’ theory of memory as malleable? What implications might one theory have for the other? How does this relate to maintaining health in older age?
