Repetitive Transcranial Magnetic Stimulation (rTMS) for the Treatment of Depression & Other Neuropsychiatric Symptoms After Traumatic Brain Injury (TBI)

Ability to Inhibit Cognitive Interference as Assessed by the Stroop Color Word Test (SCWT)

The SCWT is used to assess the ability to inhibit cognitive interference that occurs when the processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute. Participants are required to read three different tables as fast as possible. Two of the tables represent the "congruous condition" in which participants are required to read names of colors printed in black ink and name different color patches. In the third table, "incongruous condition" the color-words are printed in a different color in (ie: the word "red" is printed in green ink). Within this third table, participants are required to name the color of the ink instead of reading the word. The score is based on the number of items completed, which ranges from 0 to 100, with a higher score reflecting a better outcome.

Immediate Recall as Assessed by Hopkins Verbal Learning Test (HVLT)

The Hopkins Verbal Learning Test (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. The number of correctly-recalled words in each trial is recorded (maximum of 12). The score is a sum of all the correctly-recalled words from each trial, for a maximum score of 36.

Time frame: Mean at baseline and 16 weeks

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)

Time frame: Mean at baseline and 16 weeks

Delayed Recall as Assessed by Brief Visual Memory Test (BVMT)

BVMT is used to evaluate visuospatial memory abilities in neuropsychological populations. A visual display of six simple figures arranged in a 2 × 3 matrix on an 8 × 11 booklet is shown to participants for three consecutive 10-second trials. After each trial, participants are to draw as many designs as accurately as they can and in the correct location after a 25-minute delay filled with other distractor tasks. Scoring of the delayed recall is based on the accuracy of the drawings and the location of the figures. For each figure, one point is awarded to each satisfactory domain resulting in a maximum of 12-points per trial for a total score range of 0-36, with higher scores indicating a better outcome.
