Table 101Summary of findings on nonpharmacologic treatment of adult treatment-resistant depression (TRD) with strength of evidence for Tier 1 (TRD) for KQ 4a. impact of nonpharmacologic interventions on cognitive functioning

ComparisonOutcomeNumber of SubjectsStrength of Evidence*Findings
ECT vs. rTMSCognitive functioning72Insufficient1 fair trial and 1 fair cohort study: Some evidence suggests no difference between treatments, whereas some evidence suggests ECT may have deleterious impact on cognitive functioning compared with rTMS (1 study: significant effect on 1-week recall; both studies: nonsignificant effect on all other measures).
ECT vs. ECT + rTMSCognitive functioning22Insufficient1 fair trial: no significant differences in a single item measure on memory problems
rTMS vs. shamCognitive functioning101Insufficient3 trials (1 good, 2 fair): Some evidence suggests no difference between rTMS and sham, whereas some evidence suggests that rTMS improves cognitive functioning compared to sham (2 trials: significant differences in memory, verbal fluency; all other findings nonsignificant or significance not reported)

ECT = electroconvulsive therapy; rTMS = repetitive transcranial magnetic stimulation; vs. = versus
