Cognitive Dysfunction in the Addictions Study - Project 4 (P4)

Assessing the Role of Repetitive Transcranial Magnetic Stimulation on Aberrant Executive Function in the Context of Major Depressive Disorder in Adult Outpatients Seeking Treatment for Alcohol Use Disorder

• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 40 (estimated)
• Sponsor: Centre for Addiction and Mental Health · Academic / Other
• Sex: All
• Age: 18 Years – 59 Years
• Healthy volunteers: Not accepted

Summary

The prefrontal cortex, although well established as an efficacious target for the treatment of major depressive disorder (MDD), has recently come into favour as a therapeutic target for alcohol use disorders (AUD). Depressive symptoms are also highly prevalent in individuals with AUD. A number of cognitive and psychological processes stemming from the prefrontal cortex, a common treatment target for repetitive transcranial magnetic stimulation (rTMS), are disrupted in both MDD and AUD. The proposed study will enhance the development of theta burst stimulation (TBS) as a new intervention for AUD in the context of depressive symptoms and uses integrated TMS-EEG to identify neurophysiological targets of executive dysfunction in this disorder.
