LOAD = Late-Onset Alzheimer Disease

CC = Cognitive Controls

Dep+ = Any Depression with a late in life onset (i.e. DAD + LLD)

Dep− = No History of Depression

DAD = Depression of Alzheimer Disease

LOD = Late-Onset Depression

Age* = Age-at-onset for those with LOAD, and age-at-exam for cognitive controls

^**

DAD cases are significantly younger than LOAD (not DAD) cases p=0.017.
