The Effect of Cortisol Administration on Neural Correlates of Emotion in Depression
This trial is active, not recruiting.
|Treatments||hydrocortisone acetate, placebo|
|Start date||July 2016|
|End date||July 2020|
|Trial size||80 participants|
|Trial identifier||NCT02837432, 19771|
There is good evidence to suggest that the pathological version of sadness that people with Major Depression experience could be caused by the failure of the hormone cortisol to properly inhibit sadness-related brain activity in the subgenual cingulate cortex. This project investigates if the subgenual cingulate cortex has become insensitive to cortisol in patients with depression and tests for variants of the cortisol receptor genes that could predispose individuals to develop cortisol insensitivity.
|Intervention model||crossover assignment|
|Masking||double blind (subject, investigator)|
|Primary purpose||basic science|
Sadness-induced subgenual cingulate activity as measured by functional magnetic resonance imaging.
