| d2-R errors | −0.37 | 1.335 | |
| •Impairment on at least two tests, when a limited battery of neuropsychological tests is performed (i.e., the battery includes less than two tests within each of the five cognitive domains, or less than five cognitive domains are assessed) | Working memory | ||

| Digit span backwards | −0.23 | 1.11 | |
| B. Level II (comprehensive assessment) •Neuropsychological testing that includes two tests within each of the five cognitive domains (i.e., attention and working memory, executive, language, memory, and visuospatial) •Impairment on at least two neuropsychological tests, represented by either two impaired tests in one cognitive domain or one impaired test in two different cognitive domains •Impairment on neuropsychological tests may be demonstrated by: Performance ~ 1–2 SDs below appropriate norms or Significant decline demonstrated on serial cognitive testing or Significant decline from estimated premorbid levels |
