Organisation Name: Mclean Hospital
Overal Status: Recruiting
Start Date: June 4, 2019
Last Update: January 27, 2022
Lead Sponsor: Mclean Hospital
Brief Summary: Aim 1: Test the hypothesis that participants with Bipolar Disorder - Fear of Harm Phenotype have an enhanced amygdala fMRI response to fearful threatening stimuli, increased resting beta and gamma EEG spectral activity in temporal leads and blunted posterior insula response to cold when partially withdrawn from ketamine with normalization of these responses following intranasal administration of ketamine.Conditions
Aim 2. Test the hypothesis that ketamine alters response to fearful-threatening visual stimuli and cold sensation by altering functional connectivity of the amygdala and insula with the hypothalamus, thalamus, hippocampus and ventromedial prefrontal cortex, and identify specific alterations that correlate with degree of pre-post ketamine change.
Aim 3. Test the hypothesis that low-dose medicinal ketamine, unlike high-dose recreation ketamine, is not associated with an increase in number of focal areas of abnormality on morphometric scans based on duration of use.
