Table 3 Assessment of cognitive function by Wechsler memory scale

From: Evaluation of cognitive impairment in patients with major depressive disorder in remission

WMS-R subtests Patients group (n = 60) Control group (n = 60) T P
Visual memory
Figural memory, mean ± SD 3.6 ± 2.3 9.9 ± 1.7 16.6 < 0.001 HS
Visual paired associates, mean ± SD 4.8 ± 0.46 4.97± 0.1 3.1 0.08 (NS)
Verbal memory
Logical memory, mean ± SD 3.5 ± 1.4 8.2 ± 1.2 19.5 <0.001 (HS)
Verbal paired associates, mean ± SD 7.2 ± 0.6 10.2 ± 1.4 14.6 < 0.001 (HS)
Attention/concentration/psychomotor speed function
Mental Control, mean ± SD 5.3 ± 1.5 8.4± 1 13 <0.001 HS
Digit span, mean ± SD 5.2 ± 1.4 8.5 ± 1 13 < 0.001 (HS)
Visuospatial function
Visual reproduction, mean ± SD 5.5 ± 0.5 5.6 ± 0.5 1.8 0.08 (NS)
  1. There were statistically significant differences between the patient and control groups. The patients’ group scored less in cognitive functions regarding visual memory, verbal memory, attention/concentration, and psychomotor speed
