A Novel Use of a Sleep Intervention to Target the Emotion Regulation Brain Network to Treat Depression and Anxiety (R33 Phase)
Stanford University
Summary
This project is the second phase of a two-phased project investigating the impact of a proven sleep intervention, Cognitive Behavioral Therapy for Insomnia (CBT-I) on engagement of the emotion regulation brain network as a putative mechanistic target.
Description
Several lines of evidence suggest that insomnia contributes to emotionally distressing depressive mood symptoms through disruption of brain networks that regulate emotional functions. Of particular concern, insomnia is associated with an increased risk for suicide, even when accounting for the presence of other depressive symptoms. However, it is not yet know to what degree that the emotion regulation brain network is modified by the restoration of sleep, or whether the degree to which a sleep intervention engages these neural targets mediates reductions in depressive symptoms and suicidality.…

Interventions
- BehavioralCognitive Behavioral Therapy for Insomnia
CBT-I improves sleep through a combination of behavioral interventions (stimulus control (SC), sleep restriction (SR)), cognitive therapy (CT) as well as additional components such as mindfulness training and sleep hygiene education. SC is an intervention that re-establishes the connection between the bed/bedroom with sleep to help develop a more consistent sleep/wake pattern. SR leads to higher quality sleep by reducing excessive time spent in bed to the actual amount of sleep, thereby creating mild sleep deprivation and increasing the homeostatic sleep drive. Like CT for other disorders, CT for insomnia targets maladaptive thoughts and cognitions that may interfere with sleep.
