This study evaluates an accelerated schedule of theta-burst stimulation for depressive symptoms in psychiatric inpatients. A small pilot study (n=22) will be carried out to demonstrate feasibility, using the FDA-approved stimulation site for depression treatment (L-DLPFC). Participants will be offered stimulation at the anterior cingulate cortex (ACC).
This study intends to investigate whether modifying stimulation parameters enables typical 6-8 week long rTMS protocols to be compressed to only five days. The influence of this accelerated protocol on the length of patient stay in the hospital will be investigated.

Participants will receive iTBS (intermittent theta burst stimulation) to the left DLPFC. Stimulation intensity will be standardized at 80% of resting motor threshold (adjusted for cortical depth). Stimulation will be delivered using the Brainsway TMS system.

Change in Montgomery Asberg Depression Rating Scale (MADRS) Score
A 10-item clinician-administered scale, designed to be particularly sensitive to antidepressant treatment effects in patients with major depression. Severity gradations for the MADRS have been proposed: 9-17 = mild depression, 18-34 = moderate depression, and ≥ 35 = severe depression. Scores range from 0-60 (higher scores are more symptomatic). Response is defined as a 50% reduction or greater in MADRS score compared to baseline. Remission is defined as a MADRS score of \<10. Data are presented as a raw score point change.
Time frame: After all stimulation sessions have been completed (approximately 48 hours after the final session)
Change in Scale of Suicidal Ideation (SSI) Score
19-item clinician administered assessment to measure the intensity, pervasiveness, and characteristics of suicidal ideation in adults. Scores range from 0-38. Higher scores indicate more suicidality. Data are presented as a raw score point change.
Time frame: After all stimulation sessions have been completed (approximately 48 hours after the final session)
Change in Hamilton Rating Scale for Depression Six Item (HAMD-6) Score
Clinical assessment measuring depressive symptoms. Scores range from 0-24 with scores \>5 indicating clinical levels of depressive symptoms (higher scores are more symptomatic). Data are presented as a raw score point change.
Time frame: After all stimulation sessions have been completed (approximately 48 hours after the final session)
Change in Young Mania Rating Scale (YMRS)
The Young Mania Rating Scale (YMRS) is one of the most frequently utilized rating scales to assess manic symptoms. The scale has 11 items and is based on the patient's subjective report of his or her clinical condition. There are four items that are graded on a 0 to 8 scale (irritability, speech, thought content, and disruptive/aggressive behavior), while the remaining seven items are graded on a 0 to 4 scale. These four items are given twice the weight of the others to compensate for poor cooperation from severely ill patients. Typical YMRS baseline scores can vary a lot. They depend on the patients' clinical features such as mania (YMRS = 12), depression (YMRS = 3), or euthymia (YMRS = 2). Data are presented as a raw score point change.

Change in Beck Depression Inventory II (BDI-II)
The Beck Depression Inventory (BDI-II) is a 21-item, self-report rating inventory that measures characteristic attitudes and symptoms of depression. BDI-II items are rated on a 4-point scale ranging from 0 to 3 based on severity of each item. The maximum total score is 63. Scores: 0-13= minimal depression, 14-19=mild depression, 20-28=moderate depression, 29-63=severe depression. Data are presented as a raw score point change.
Time frame: After all stimulation sessions have been completed (approximately 48 hours after the final session)
Change in Quick Inventory Depressive Scale-Self Reported (QIDS) Score
Self-report measure of depressive symptoms. The questionnaire consists of 16 questions. Each question can score between 0 to 4 points. Severity of depression is determined as follows: 0=None, 1=Mild, 2=Moderate, 3=Severe, 4=Very Severe. Total scores range from 0-27. Total scores: 0-5= no depression, 6-10= mild depression, 11-15= moderate depression, 16-20= severe depression, 21-27= very severe depression. The total score is obtained by adding the scores for each of the nine symptom domains of the DSM-IV MDD criteria: depressed mood, loss of interest or pleasure, concentration/decision making, self-outlook, suicidal ideation, energy/fatigability, sleep, weight/appetite change, and psychomotor changes (Rush et al. 2003). Data are presented as a raw score point change.

Change in Pittsburgh Insomnia Rating Scale-20 Item Version (PIRS-20) Score
Self-report, 20 item scale to determine patient's insomnia level. Each question can be scored between 0-3. 0=not bothered at all slightly bothered moderately bothered severely bothered Total score is calculated by adding up all questions (i.e. Q1+Q2+...Q20). One missing item is allowed, pro-rate if missing one item....i.e. (sum/count)\*20. Minimum Score = 0 (good); Maximum Score = 60 (bad). Data are presented as a raw score point change.

Change in Resting-state Recordings and TMS-evoked Potentials in EEG Data.
For the first and last stimulation session, EEG recording will be made before (resting-state EEG) and during (TMS-evoked potentials) the stimulation.

Biomarker Analysis in Patient Blood (Plasma) Samples
Blood (plasma) samples will be collected before and one month after stimulation. Blood collection is conducted by the registered hospital phlebotomist (following same protocol of a routine blood test). Blood samples will be analyzed by our collaborators at the Open Medicine Institute. Specifically, samples will be used for DNA/RNA extraction and analyses will be done to determine potential gene targets. Presence of inflammatory markers (cytokines) will also be determined. All analyses of blood samples will be conducted in the Open Medicine Institute.
