Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Two acute (24 IU) treatment 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 (fMR) protocol. The fMRI protocol will involve showing participants a brief task involving pictures of human faces expressing different emotions.
Intervention code [1] 286199 0
Treatment: Drugs
Comparator / control treatment
Placebo, a saline solution without the active (peptide) ingredient.
Healthy controls will as be used in comparisons to the HD patients.
Control group
Placebo

Outcomes
Primary outcome [1] 288500 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 (Huntington's disease) group for differences in brain response (e.g., in the amygdala) between placebo and oxytocin conditions.
Timepoint [1] 288500 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] 300333 0
Using the fMRI data, the patients with Huntington's disease will be compared to controls on brain response (e.g., amygdala) under normal (placebo) conditions to see whether hyper- or hypo-activity is present.
Timepoint [1] 300333 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 HD using a double-blind placebo controlled intranasal oxytocin design and two MRI techniques involving fMRI and diffusion tensor imaging (DTI).
