Cognitive Training as an Adjunct to Ketamine in Real-world Clinics
This interventional trial (n=600) will evaluate whether cognitive training can enhance or extend the rapid antidepressant effects of ketamine in patients already receiving ketamine treatment as part of their clinical care.
Detailed Description
This randomised, parallel-group trial will enrol approximately 600 patients already clinically receiving IV ketamine to test whether adjunctive web-based cognitive training versus sham training can enhance or prolong antidepressant response.
Cognitive training consists of self-administered 15–20 minute sessions via a web app delivered during the induction and post-induction phases; primary outcomes include change in depressive symptoms (MADRS) and durability of response.

Participants
Inclusion Criteria
- Inclusion Criteria:
- 1. be between the ages of 18 and 80 years
- 2. score ≥20 on the Montgomery-Asberg Depression Rating Scale (MADRS)
- 3. per SCID-5-RV interview, meet DSM-5 diagnostic criteria for at least one of the following: Major Depressive Disorder, Bipolar Disorder (I or II), Persistent Depressive Disorder, or Other Specified Depressive or Bipolar Disorder
- 4. exhibit treatment resistance, defined as: (a) failure to respond to ≥1 adequate trials of an evidence-based treatment for mood disorder [per the Antidepressant Treatment History Form-Short Form Modified Score Sheet (ATHF-SF-Modified)] and/or (b) failure to respond to ≥1 adequate mood stabilizer or other evidence-based treatment trials (for bipolar depression patients) and/or (c) a history of intolerance during attempted trials of evidence-based treatments for mood disorders and/or (d) failure to respond to ≥1 prior treatment trials (e.g., medication, psychotherapy) for Post Traumatic Stress Disorder (PTSD)
- 5. be eligible and clinically enrolled for upcoming IV ketamine at one of our study clinics according to that clinic's standard intake procedures
- 6. agree to maintain a stable schedule of concomitant psychiatric medications throughout the ketamine induction phase (minor adjustments to PRN meds and timing of meds are allowable), and for 4 weeks post-induction phase
- 7. possess a level of judgment and understanding sufficient to agree to all procedures required by the protocol and must sign an informed consent document
- 8. be willing and able to provide names and contact information for at least 1 additional emergency contact in the patient's proximal geographic area (in addition to the ketamine treatment team at the enrolling site)
Exclusion Criteria
- Exclusion Criteria:
- 1. Presence of current/acute psychosis, mania, or dementia, or a diagnosis of developmental disorder with significant language and/or intellectual impairment (e.g., autism spectrum disorder)
- 2. Current/acute suicide risk with intent to act, defined as CSSRS past-week ideation score ≥ 4 among outpatients; patients engaged in residential or inpatient care at the time of enrollment need not meet this CSSRS score criterion, as their current/acute suicide risk is extremely low by virtue of the residential/inpatient, round-the-clock care they are already receiving at time of enrollment
- 3. Concern for dementia or significant cognitive decline, per interviewer observations and impressions during screening assessments
- 4. Current pregnancy or breastfeeding
- 5. English reading level <5th grade as per patient self-report Rationale: to ensure adequate reading comprehension for verbal ASAT/sham stimuli which are presented in English
