Cognitive impairment in patients with systemic lupus erythematosus and neuropsychiatric symptoms of different origins
| Global cognitive function | Learning and memory | Executive function and complex attention | Psychomotor speed | |
| All patients (n=151)* |
8 (5) | 70 (46) | 57 (39) | 69 (46) |
| Minor/non-NPSLE (n=115) |
5 (4) | 50 (44) | 43 (38) | 55 (49) |
| Inflammatory NPSLE (n=24) |
3 (13) | 14 (58) | 12 (50) | 12 (50) |
| Ischaemic NPSLE (n=12) |
0 (0) | 6 (50) | 2 (17) | 2 (17) |
Data represent n (%) of patients with cognitive impairment (defined as a T-score ≤40).
*The percentages were calculated from total number of patients with available scores. Minor/non-neuropsychiatric systemic lupus erythematosus (NPSLE): 113/115 for global cognitive function, psychomotor speed and executive function and complex attention; Inflammatory NPSLE: 23/24 for global cognitive function; Ischaemic NPSLE: all tests available.
