NCT02935595

Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • Cortical Excitability in the Dorsolateral Prefrontal Cortex (DLPFC) as Assessed by Transcranial Magnetic Stimulation-evoked Activity Detected by Electroencephalography (TMS-EEG)

    Transcranial magnetic stimulation (TMS) of the left dorsolateral prefrontal cortex (DLPFC) was performed, and electroencephalography (EEG) recording was performed during TMS stimulation. Data is reported as the local mean field amplitude-area under the curve (LMFA-AUC) from a subset of EEG electrodes around the TMS stimulation site.

    Baseline

  • Cortical Excitability in DLPFC Using TMS-EEG

    Transcranial magnetic stimulation (TMS) of the left dorsolateral prefrontal cortex (DLPFC) was performed, and electroencephalography (EEG) recording was performed during TMS stimulation. Data is reported as the local mean field amplitude-area under the curve (LMFA-AUC) from a subset of EEG electrodes around the TMS stimulation site.

    4 hours

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Be between 18-60 years of age
  • Meet criteria for Treatment Resistant Depression (defined as two or more unsuccessful trials of antidepressants at an adequate dose for at least 4 weeks)

You may not qualify if:

  • Diagnosed with intellectual disability, eg. Mental retardation, neurodegenerative diseases, eg. Early onset neurocognitive disturbances such as frontotemporal dementia or behavioral disorders, eg. adult onset Attention Deficit Hyperactivity Disorder,
  • Diagnosed with Bipolar Disorder (BD),
  • Diagnosed with personality disorders,
  • Previously or currently diagnosed with psychosis (schizoaffective disorder -SAD) or schizophrenia - SCZ),
  • Current major medical problems that affect brain anatomy, neurochemistry, or function, e.g., obstructive sleep apnea requiring Continuous Positive Airway Pressure (CPAP), liver insufficiency, kidney insufficiency, cardiovascular problems, systemic infections, cancer, auto-immune diseases, and any brain disorder (seizure disorder, stroke, dementia, degenerative neurologic diseases); history of any brain diseases, including seizures, stroke, meningitis, encephalitis, dementia, degenerative brain diseases, and head injury with loss of consciousness for any period of time,
  • Diagnosed specifically with a cardiovascular disorders such as Hypertension, Arrhythmias, Chronic Heart Failure, Myocardial Infarction (MI) or suffering from Chronic Obstructive Pulmonary Disease (COPD) or asthma. Cardiac clearance prior to enrolling in the study and medical records from physician will be required per patient's Primary Care Physician.
  • Patients with increased risk of laryngospasm, active upper respiratory infections, respiratory depression, increased intracranial pressure, thyroid disease, or porphyria,
  • Current substance abuse or dependence. Only patients who achieved stable, full remission for at least 6 months will be included
  • Pregnancy or Breast feeding. All female in reproductive age will undergo pregnancy tests. Female participants will be required to provide evidence of use of contraceptives during the course of the study,
  • Unable to understand the design and requirements of the study.
  • Unable to sign the informed consent for any reason.
