Differences in PTSD symptom severity measured with the CAPS at one-and-a-half months post trauma follow-up.
fMRI substudy: brain reactivity and connectivity measures to emotional face matching and traumatic script imagery tasks.
Achtergrond van het onderzoek
1-Oct-2014:
Risk factors for developing PTSD early post-trauma trauma include high initial levels of distress, a lack of social support, and dysregulations of the fear and stress system. We propose a significant role for the “bonding” hormone oxytocin in reducing adverse consequences of trauma, namely through regulating stress and fear responses and increasing the susceptibility for positive effects of social interaction. Oxytocin is synthesized and released in the presence of safe social contact and is implicated in trust and pair-bonding. In addition, oxytocin regulates fear- and stress-responses at the level of amygdala, the autonomic nervous system and hypothalamic-pituitary-adrenal axis.
In this study we will examine the effects of multiple intranasal oxytocin administrations on the development of trauma-related psychopathology symptoms, and the effects of a single oxytocin administration on brain reactivity and connectivity in recently traumatized individuals.
The results will provide unique clinical data on the role of oxytocin in psychobiological responses to trauma, crucial for the application of oxytocin in preventing or treating trauma-related disorders.
Doel van het onderzoek
We expect that oxytocin treatment alone will reduce trauma-related psychopathology at one-and-a-half month follow-up compared to participants who received placebo.
fMRI substudy: we expect that a single oxytocin administration will attenuate neural responses to threat- and trauma-related stimuli compared to placebo.
Onderzoeksopzet
CAPS scores: One and a half months post trauma follow up.
fMRI substudy: max 11 days post-trauma.
Onderzoeksproduct en/of interventie
Intranasal oxytocin (2dd 40 IU for 7 days), or intranasal saline placebo (2dd 10 puffs for 7 days). The intranasal treatments start approximately on day 9 post trauma.
fMRI substudy: a single administration of oxytocin (40 IU) or placebo (10 sprays) 45 min prior to functional MRI scanning.
