Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Two acute treatment (24 IU each) conditions including; a) intranasal placebo, and b) intranasal oxytocin (Syntocinon, Novartis, Switzerland). The two treatment conditions will be separated by a minimum of 1 week (washout period). The nasal sprays will be administered 50 mins prior to the functional magnetic resonance (fMRI) protocol. The fMRI protocol will be one hour in duration and involve showing participants a brief task involving pictures of human faces expressing different emotions. The fMRI protocol will also involve taking structural, resting state and diffusion tensor imaging (DTI) images of the brain while the participant is not engaged in a task.
Intervention code [1] 290101 0
Treatment: Drugs
Comparator / control treatment
Placebo, a saline solution without the active (peptide) ingredient.
Healthy controls will be used in comparisons to the Body Dysmorphic Disorder (BDD) patients.
Control group
Placebo

Outcomes
Primary outcome [1] 293013 0
Functional MRI (fMRI) data will be collected in response to an emotional face expression task. The fMRI data will be compared within the patient (Body Dysmorphic Disorder) group for differences in brain response (e.g., in the amygdala) between placebo and oxytocin conditions.
Timepoint [1] 293013 0
The data will be collected in the 50-80 min post drug administration and will be analysed post all data collection.
Secondary outcome [1] 310145 0
Using the fMRI data, the patients with BDD will be compared to healthy controls on brain response (e.g., amygdala) under normal (placebo) conditions to see whether any differences in brain activity is present.

Using the DTI and structural MRI data, the whole-brain and white matter structure of the brains of patients with BDD will be examined in comparison to the healthy control group to see if any structural or white matter differences are present.
Timepoint [1] 310145 0
The data will be collected in the 50-80 min post drug administration and will be analysed post all data collection.

Summary
Brief summary
The overall aim of the current study is to examine the brain correlates of emotion recognition in patients with Body Dysmorphic Disorder using a double-blind placebo controlled intranasal oxytocin design and two MRI techniques involving fMRI and diffusion tensor imaging (DTI).
