New data has caused the principal investigator to decide that the study no longer makes sense to conduct as it is designed. This is not a suspension of IRB approval.

Repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for MDD, but the overall effect sized of the treatment is equivalent to antidepressant pharmacotherapy, and responses are highly variable. Given that rTMS is usually given to patients who have failed pharmacotherapy, a more effective alternative is needed.
Therefore, this study will combine computerized cognitive training (CCT) during standard rTMS treatments and assess its feasibility, tolerability, and changes in cognitive control performance and depression symptoms.
Participants that agree to the study and meet eligibility will receive standard rTMS (generally 25-36 daily treatments) along with CCT (starting on day 5 of treatment until the pre-taper treatment). In addition, to CCT participants will be asked to complete assessments before and after treatment
This project will also have a registry for participants that are approached to be in the clinical trial with the CCT but don't wish to be enrolled. Although the registry will be available for these participants, the information entered into this ClinicalTrials.gov registration will reflect the clinical trial portion of this project.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Computerized Cognitive Training (CCT) | Experimental | The patients will receive CCT during their standard rTMS treatments (after having 5 days of treatment until the pre-taper treatment). |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Computerized Cognitive Training (CCT) | Other | After having four rTMS sessions without CCT, the patients will perform CCT (starting day 5) during the rTMS session, which typically last from 20-40 minutes. A course of rTMS therapy includes from 25-36 treatments, given daily, until the last 5-6 treatments, given as a 'taper' over 2 weeks. CCT will be paired with rTMS up until the taper begins. In addition, they will have assessments prior to and after the therapy. |
| Measure | Description | Time Frame |
|---|---|---|
| Feasibility assessed by percentage of CCT sessions completed during rTMS | Percentage CCT sessions completed: (number of sessions completed/number of sessions assigned) X 100 | approximately 30 days (usually 20-30 sessions) |
| Measure | Description | Time Frame |
|---|---|---|
| Time on task during treatment | Percentage time on task: (Time engaged with task/total time of task assigned)X100, averaged over all active sessions | For each day: 45 min; for entire treatment: approx 30 days |
| Acceptability of CCT |
