ARWMC (Age Related White Matter Changes)
White matter lesions (WML)
|
|
0 | no lesion (including symmetrical, well-defined caps or bands) |
1 | focal lesions |
2 | an incipient confluence of lesions |
3 | diffuse involvement of the entire region, with or without the involvement of U fibers |
Basal ganglia lesions | |
0 | no lesion |
1 | 1 focal lesion (≥ 5 mm) |
2 | > 1 focal lesion |
3 | confluent lesions |
- white matter lesions (WMLs) on MRI are defined as bright (hyperintense) lesions ≥ 5 mm on T2, PD, or FLAIR images
- WMLs on NCCT are defined as hypodense areas ≥ 5 mm
- the following areas are scored (each hemisphere separately):
- frontal
- parieto-occipital
- temporal
- infratentorial, including the cerebellum
- basal ganglia (striatum, globus pallidus, thalamus, internal and external capsule, and insula)
- FAZEKAS scale is easier to use in routine clinical practice
