Relationships between whole brain diffusion tensor imaging and dementia severity measures
| DTI Measure | AAN | MSK | Karnofsky |
|---|---|---|---|
| Whole brain FA | −.63* | −.59* | .64* |
| Whole brain ADC | .24 | .30 | −.43 |
Note.—Relationships are expressed as Spearman correlation coefficients. DTI indicates diffusion tensor imaging; AAN, dementia rating based on American Academy of Neurology criteria; MSK, dementia rating based on Memorial Sloan Kettering criteria; FA, fractional anisotropy; ADC, apparent diffusion coefficient.
