Brief Summary

The CogniTReaD study is a pilot clinical trial that will compare the effects of active accelerated bilateral sequential theta burst stimulation (absTBS) and sham or inactive treatment. The goal is to see if absTBS can help older adults with treatment-resistant depression (TRD) by looking at dual-task cost and mood, as well as other cognitive functions, anxiety levels, quality of life, and physical performance, while also checking for any treatment side effects. The study will recruit participants who will receive different study treatments in a specific order. The study will be double-blinded, meaning neither the participants nor the researchers will know who is receiving which treatment. The study will include people who are 50 years old or older and diagnosed with treatment-resistant depression with at least a moderate severity of depression. This study seeks to discover if absTBS can modify a dementia risk marker (i.e., dual-task cost and depression) in older patients with TRD, and to determine the effect size for larger investigations in the future.

Detailed Description

The CogniTReaD study is a two-arm, sham-controlled, double-blinded, treatment-sequenced, randomized clinical trial that will evaluate and explore the effects and safety of accelerated bilateral sequential theta burst stimulation (absTBS) compared to sham control in terms of improving dual-task cost, cognitive functions, depression, other outcomes (anxiety, health-related quality of life, activities of daily living, global impression, and other gait performance), and occurrence of adverse events (AE) measured at Week 2 (i.e., posttreatment acute effects) in older adults with treatment-resistant depression (TRD). We shall also evaluate the effects and safety of absTBS on improving dual-task cost, cognitive functions, depression and occurrence of AE in terms of AE occurrences measured at Week 6, Week 8, and Week 10 (i.e., posttreatment delayed effects) in older adults with TRD.

An AE is defined as any untoward medical occurrence associated with any of the study interventions (active absTBS or sham) whether or not considered related to the study intervention.

A serious AE to any serious and unforeseen occurrence related or possibly related to the participation in the study that can lead to hospitalization, disability, or death.
