Meanings of definite ad in English

Objective: To compare lifetime dementia risk estimates among relatives of white and African American probands with probable or definite AD.

Since the pathologic results of 119 subjects did not meet the criteria for definite AD, we labeled them as Alzheimer "mimics".

In fact, despite a range of neuropsychological findings, none of the subjects in this series met neuropathological criteria for a diagnosis of definite AD.

All of the DLB cases had neuropathologic evidence of AD sufficient to meet CERAD criteria for a diagnosis of definite AD plus nigral Lewy bodies.
