Repeated Partial Sleep Deprivation to Augment SSRI Response in Depression
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Depression is common and associated with social and economic costs. Although antidepressant medications are an effective treatment for depression, it can take as long as 6-8 weeks before symptoms improve, and 20-35% of individuals who use antidepressants still experience depression symptoms.
New treatments that accelerate response to antidepressants are important to reduce the burden of depression. The objectives of the proposed study are (1) to evaluate the effects of partial sleep deprivation compared to no sleep deprivation for improving response to 8 weeks of fluoxetine 20-40 mg treatment and (2) to examine the underlying sleep mechanisms of treatment response.
Participants who are eligible for the study will be randomly assigned to one of three sleep schedules for a 2-week period while taking fluoxetine: no sleep deprivation (8 hours time in bed), late bedtime (6 hours time in bed, with 2 hour bedtime delay) or early risetime (6 hours time in bed, with 2 hour advancement of rise time). Participants will spend a total of 7 nights in our sleep laboratory and will be followed on fluoxetine for an 8-week period.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Hamilton Rating Scale for Depression-17 Item Minus Sleep Items
Time Frame: Post-treatment (8 weeks)
|
Total score on a clinician-rated measure of depressive symptoms, minus 3 sleep items Total score range: 0-46.
Higher scores represent more severe depression.
|
Post-treatment (8 weeks)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Quick Inventory of Depressive Symptoms (QIDS)
Time Frame: Post-treatment (8 weeks)
|
Patient-reported depression symptom severity at post-treatment, total score.
Total scores range from 0 to 27.
Higher scores represent more severe depression.
|
Post-treatment (8 weeks)
|
Pittsburgh Sleep Quality Index
Time Frame: Baseline, 2 weeks and 8 weeks post-treatment
|
Self-report measure of sleep quality.
The Pittsburgh Sleep Quality Index is a validated scale which measures self-reported sleep quality based on a wide variety of questions (duration, quality, disturbances, medication, etc.) and converts them to a scale which ranges from 0 to 21 where 6 or higher denotes poor sleep quality.
|
Baseline, 2 weeks and 8 weeks post-treatment
|
Change in EEG Sleep Measures I: Total Sleep Time
Time Frame: Baseline, 2 weeks, 8 weeks
|
Measurement of EEG activity during sleep using polysomnography: Total Sleep Time is the length of time from sleep onset to final wake up minus any wakefulness during the night.
It reflects the total amount of time asleep during the night.
|
Baseline, 2 weeks, 8 weeks
|
Change in EEG Sleep Measures II (Sleep Efficiency)
Time Frame: Baseline, 2 weeks, 8 weeks
|
Measurement of EEG activity during sleep using polysomnography: Sleep efficiency [(total sleep time/time in bed)*100]
|
Baseline, 2 weeks, 8 weeks
|
Change in Neuropsychological Functioning: Memory
Time Frame: Baseline, 2 weeks, 8 weeks
|
Change in different aspects of thinking (e.g., memory, attention, executive functioning)
|
Baseline, 2 weeks, 8 weeks
|
Change in Neurologic Functioning: Reaction Time
Time Frame: 0, 2, 8 weeks
|
Reaction Time is measured using a modified Go/No-go test of inhibitory control
|
0, 2, 8 weeks
|
Neurological Function (Emotional Perception)
Time Frame: 0 weeks, 2 weeks, 8 weeks
|
Emotional Perception is measured based on the percent of faces whose emotions are correctly identified using the Facial Emotion Perception Test (FEPT)
|
0 weeks, 2 weeks, 8 weeks
