Low Dose Intravenous Ketamine in Treatment Resistant Depression Patients

Completed · Phase 2

Conditions studied: Treatment Resistant Depression

In brief

The primary goal of the project is to study the effect of Ketamine on cortical neurophysiological function in TRD patients. The proposal employs robust and non-invasive neurophysiological techniques TMS and EEG to investigate the cortical excitability and oscillatory activity in patients with treatment resistant depression.
