Summary

Major depressive disorder (MDD) is associated with significant cognitive impairment throughout the life-course, which may progress toward MCI and dementia with age. Antidepressant medications are the first line of treatment; however, they fail to adequately address cognitive deficits and prevent relapse. Sustained cognitive impairment into euthymic periods may relate to underlying neurobiological changes, which could potentially be addressed through Cognitive Behavioural Therapy (CBT). Notably, CBT has been shown to improve cognitive domains including divided attention, memory, and processing speed while preventing depression relapse. Midlife represents a critical period in which shared neurobiological factors (such as brain changes on a vascular, morphological, and functional level) underlying depression and cognitive impairment could accelerate toward MCI and dementia. An updated understanding of neurobiological correlates of midlife depression and CBT response through multimodal neuroimaging is critical to improving affective and cognitive outcomes in this population.

The overarching objective of this project is to use multimodal neuroimaging to quantify the neurobiological and clinical impact of CBT in midlife depression. Specifically, we aim to:

1. Investigate the clinical impact of CBT on cognitive function and mood outcomes in midlife depression
2. Examine functional connectivity and microstructural determinants of CBT response in midlife depression using neuroimaging
3. Identify vascular modulators of neural connectivity and CBT response in midlife depression.

We hypothesize that midlife depression will be associated with functional and structural neural connectivity changes, which will be accompanied by vascular pathology. Adequate CBT response (i.e., improvements in mood and cognitive function) will be associated with amelioration of neurobiological changes.

Conditions

  • Major Depressive Disorder (MDD)

Interventions

BEHAVIORAL

Cognitive Behavioural Therapy

12 weeks of Cognitive Behavioural Therapy (CBT) will be administered. The first session will be accomplished in-person at Baycrest Hospital. After that, therapy will be conducted virtually, via video-conference. Individuals will undergo therapy once a week for approximately 1 hour, for 12-weeks. Following the 12-week period, individuals will receive three follow-up assessments with their therapist at 3, 6, and 9 months.
