Study Summary
In the treatment of Major Depressive Disorder (MDD), total sleep deprivation can produce rapid but short-lasting improvements in mood. In order to develop a new generation of treatments with rapid and sustained efficacy, a better understanding of the mechanism of action is urgently needed. One candidate mechanism is the modulation of synaptic strength mediated by glutamatergic activity as sleep deprivation has been suggested to increase synaptic strength. Although determining how sleep deprivation impacts the glutamatergic system is essential to isolating its mechanism of action, the invasive nature of most assessment methods has limited our ability to do so in humans. The proposed research aims to determine if changes in glutamatergic activity, reflecting the modulation of synaptic strength, underlie the antidepressant effects of sleep deprivation. In this project, the investigators will utilize a novel measure of glutamate imaging, GluCEST, to assess changes in glutamatergic activity, in addition to using a proxy measure, waking EEG theta activity, to assess synaptic strength following total sleep deprivation. Ten individuals (aged 18-85) with a DSM-V diagnosis of MDD will undergo baseline GluCEST imaging and waking EEG prior to and following approximately 30 hours of total sleep deprivation. Both clinician-administered and subjective mood measures will be collected. It is predicted that sleep deprivation will improve mood and increase glutamatergic activity and synaptic strength. Results from this project have the potential to identify the modifiable mechanisms by which rapid antidepressants work which could ultimately stimulate the development of novel interventions that work through the modulation of glutamatergic activity.
