TBI Depression, co-morbid psychiatric symptoms
Brief summary
Traumatic brain injury (TBI) is frequently complicated by depression and other problems such as post traumatic stress disorder (PTSD), sleep disturbance, cognitive deficits and behavioral problems. Untreated depression can lead to reduced productivity and poor global outcome. There is no Food and Drug Administration (FDA) approved drug for the treatment of TBI-related depression. The overarching goal of this small study is to determine the effectiveness of low frequency right (LFR) rTMS for the treatment of post-TBI depression and co-occurring psychiatric symptoms. Repetitive transcranial magnetic stimulation (rTMS) is a brain stimulation technique. It involves generating a brief magnetic field in a coil that is placed on the scalp. The magnetic field passes through the skull and induces a weak electrical current in the brain that briefly activates neural circuits at the stimulation site. Adults aged 18 and older, with a history of head injury of mild or moderate severity , who are currently experiencing symptoms of clinical depression may join the study.
Interventions
LFR rTMS will be delivered at the Brain Stimulation Program at The Johns Hopkins Hospital with a Magstim Super Rapid 2 stimulator with a focal double 70-mm air cooled coil. LFR rTMS will be administered to the Experimental Group. Control patients will receive treatment using an identically appearing coil that produces the same sound and is the same weight as the active coil, but has negligible magnetic field strength.

Delayed Recall as Assessed by Hopkins Verbal Learning Test (HVLT)
The HVLT consists of a 12-item word list, composed of four words from each of the three semantic categories. The subject is instructed to listen carefully as the examiner reads the word list and attempt to memorize the words. The word list is then read to the subject at the approximate rate of one word every 2 seconds. This is done for three trials. After the third learning trial, the patient is read 24 words and is asked to say yes after each word that appeared on the recall list (12 targets) and no after each word that did not (12 distractors). Half of the distractors are drawn from the same semantic categories as the targets (related distractors) and half are drawn from other categories (unrelated distractors). The number of correctly-recalled words in each trial is recorded (maximum of 12 per trial). The score is the sum of all the correctly-recalled words from each trial, for a maximum of 36. T-scores are reported (average T-score of 50 (ranges 40-60)
