Summary

This trial is testing different medication strategies to help older adults whose depression hasn't improved with standard treatments. Participants will try new combinations or replacements of their current antidepressants. The goal is to find more effective treatments and understand how these changes affect memory and brain function.

Who is the study for?
This trial is for adults aged 60 and older with treatment-resistant depression, meaning they haven't gotten better after trying at least two different antidepressants. They must have a diagnosis of Major Depressive Disorder and a certain level of depressive symptoms. People with bipolar disorder, schizophrenia, dementia, severe hearing loss, unstable illnesses like uncontrolled diabetes or high suicide risk cannot join.
What is being tested?
The study tests whether adding Aripiprazole or Lithium to current treatment helps more than switching to Bupropion or Nortriptyline in older adults with resistant depression. It also looks at how these treatments affect memory, attention and brain structure/function over time.
What are the potential side effects?
Possible side effects include weight gain, sleepiness or insomnia, headaches, dry mouth from Aripiprazole; seizures from Bupropion; thirstiness, tremors from Lithium; and constipation or blurred vision from Nortriptyline.

Trial Design

5Treatment groups
Experimental Treatment
Group I: Switch to NortriptylineExperimental Treatment1 Intervention
Taper from current antidepressant therapy. Start on nortriptyline tablets starting at 1 mg per kg of body weight daily, titrated per blood level to 80-120 ng/ml.
Group II: Switch to BupropionExperimental Treatment1 Intervention
Taper from current antidepressant therapy. Start bupropion once-daily extended, titrated from 150-300 mg daily based on symptom severity and side effects.
Group III: Lithium AugmentationExperimental Treatment1 Intervention
Augment current antidepressant treatment with lithium carbonate tablets starting at 300 mg daily, titrated per blood level to 0.4-0.6 mEq/L (milliequivalents/liter).
Group IV: Bupropion AugmentationExperimental Treatment1 Intervention
Augment current antidepressant treatment with bupropion once-daily extended release, titrated from 150-300 mg daily based on symptom severity and side effects.
Group V: Aripiprazole AugmentationExperimental Treatment1 Intervention
Augment current antidepressant treatment with aripiprazole (tablets), titrated from 2-15 mg daily based on symptom severity and side effects.
