ABSTRACT
BACKGROUND: This randomized, open-label study examined the therapeutic effects of Neurocognitive Adaptive Training for Depression (NCAT-D) combined with selective serotonin reuptake inhibitors (SSRIs) on cognitive impairment among patients with late-life depression (LLD).
METHOD: Study data were collected from May 5, 2021, to April 21, 2023. Outpatients who met the diagnostic criteria for major depressive disorder according to the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (i.e., a total score on the 17-item Hamilton Depression Rating Scale (HAMD-17) ≥ 18 and a total score on the Montreal Cognitive Assessment scale (MOCA) < 26) were recruited at Beijing Anding Hospital. These participants were randomly assigned to receive up to 12 weeks of NCAT-D and SSRIs treatment (n = 57) or SSRIs with a control treatment (n = 61). Primary outcomes included changes in Alzheimer’s Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) scores from baseline to week 12 between the two groups. Assessments were conducted at baseline, after 2 weeks, 4 weeks, 8 weeks, and at 12 weeks. Mixed model repeated measures (MMRM) analysis was performed on modified intention-to-treat (mITT) and completer populations.
RESULTS: The full analysis set (FAS) included 118 patients (NCAT-D and SSRIs group, n = 57; SSRIs and Control group, n = 61). During the 12-week study period, MMRM analysis revealed a significantly greater reduction in cognitive function (as indicated by ADAS-cog total scores) from baseline to post-treatment in the NCAT-D and SSRIs group compared to the SSRIs and Control groups [(F (1,115) = 13.65, least-squares mean difference [95% CI]: -2.77 [- 3.73, — 1.81], p < 0.001)]. The intervention group showed a significantly greater reduction in HAMD-17 scores compared to the control group [MMRM, estimated mean difference (SE) between groups: -3.59 [- 5.02, — 2.15], p < 0.001]. There was no significant difference in the incidence of adverse events between the two groups.
CONCLUSIONS: NCAT-D combined with SSRIs was efficacious and well tolerated in LLD patients with cognitive impairment.
