Bracoud L, Klein G, Lyons M, et al. Validation of 3‐ and 5‐point severity scales to assess ARIA‐E. Alzheimer's Dement (Amst). 2023;15:e12503.
In Table 1, the formatting of the cells was incorrect and suggested that amyloid‐related imaging abnormality – edema (ARIA‐E) with the greatest lesion extent being < 5 cm and with multiple regions affected, should be categorized as 1 (Mild) using the SSAE‐3 scale; as opposed to being correctly categorized as 2 (Moderate). Please see the corrected Table 1 below.
TABLE 1.
Three‐point and 5‐point Severity Scales of ARIA‐E.
| ARIA‐E extent | ARIA‐E focality | SSAE‐3 | SSAE‐5 |
|---|---|---|---|
| No ARIA‐E | N/A | 0 | 0 |
| <5 cm | Monofocal | 1 (Mild) | 1 (Mild) |
| <5 cm | Multifocal | 2 (Moderate) | 2 (Mild+) |
| 5–10 cm | Monofocal | 2 (Moderate) | 3 (Moderate) |
| 5–10 cm | Multifocal | 2 (Moderate) | 4 (Moderate+) |
| >10 cm | Monofocal | 3 (Severe) | 5 (Severe) |
| >10 cm | Multifocal | 3 (Severe) | 5 (Severe) |
Abbreviations: ARIA‐E, amyloid‐related imaging abnormalities – edema; N/A, not applicable; SSAE, Severity Scale of ARIA‐E.
