NIA-Reagan diagnosis of AD (dichotomous) - OLD
Presence of AD based on NIA-Reagan diagnosis criteria - dichotomous
This variable is based on NIA-Reagan diagnostic criteria. Please see ad_adnc for the most up-to-date NIA-AA consensus pathologic diagnosis for AD.
This variable is the dichotomized version of the modified NIA-Reagan diagnosis of Alzheimer's disease. The criteria rely on both neurofibrillary tangles (Braak) and neuritic plaques (CERAD). See NIA-Reagan diagnosis of AD - 4 levels for more information.
| Value | Coding |
|---|---|
| 1 | AD present by NIA-Reagan pathology criteria (high or intermediate likelihood) |
| 0 | AD not present by NIA-Reagan pathology criteria (low likelihood or no AD) |
