NCT03741751

Brief Summary

The proposed project aims to establish the feasibility and tolerability of delivering repetitive transcranial magnetic stimulant (rTMS) combined with computerized cognitive training in patients with Schizophrenia or Schizoaffective Disorder and cognitive difficulties. The investigators will conduct a 2 week randomized controlled trial study evaluating computerized cognitive training combined with either active or sham rTMS on cognitive and functional outcomes in adults with Schizophrenia or Schizoaffective Disorder.

Outcome Measures

Primary Outcomes (1)

  • Difference in Groups on Neuropsychological Testing

    Evaluate differences in neuropsychological functioning between active and sham rTMS groups using the Screen for Cognitive Impairment in Psychiatry (SCIP). Scores are reported as Z-scores standardized to age-adjusted normative data. A Z-score of 0 represents the population mean, and each unit reflects one standard deviation from that mean. Higher Z-scores indicate better cognitive performance. Scores are interpreted relative to normative expectations rather than a diagnostic threshold. Change scores represent the value at 2 weeks minus the baseline value.

    2 weeks

Secondary Outcomes (1)

  • Change in WHODAS Total Score From Baseline to 2 Weeks

    2 weeks

Study Arms (2)

active rTMS with computerized cognitive training

EXPERIMENTAL

Participants will receive 6 sessions of active rTMS followed by a computerized cognitive training session over 2 weeks.

Device: rTMSBehavioral: Computerized cognitive training

sham rTMS with computerized cognitive training

SHAM COMPARATOR

Participants will receive 6 sessions of sham rTMS followed by a computerized cognitive training session over 2 weeks.

Behavioral: Computerized cognitive training

Interventions

rTMSDEVICE

Participants will receive either active or sham bilateral rTMS over the dorsolateral prefrontal cortex (DLPFC) for 12.5 min per side.

Also known as: High frequency repetitive transcranial magnetic stimulation
active rTMS with computerized cognitive training

All participants will receive computerized cognitive training for 40 min after each rTMS session.

Limitations and Caveats

Recruitment and follow-up were discontinued early due to the COVID-19 pandemic, resulting in a small number of participants with complete outcome data (n=6). Given the limited sample size, results are descriptive and exploratory and should not be interpreted as definitive evidence of treatment efficacy.
