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

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.

The participant points to choice on the screen and the tester manipulates the mouse to make the response. The participant tells the tester if he or she wants to change the response and the tester clicks on the screen. The score is the number of completed categories, ranging from 0-6. A higher score reflects a better outcome.

The participant points to choice on the screen and the tester manipulates the mouse to make the response. The participant tells the tester if he or she wants to change the response and the tester clicks on the screen. The score is the number of errors, ranging from 0-128. A higher score reflects a poorer outcome.

The participant tells the tester if he or she wants to change the response and the tester clicks on the screen. The score is the number of correct trials, ranging from 0-128. A higher score reflects a better outcome.

The Trailmaking B score is the number of seconds spent connecting numbered circles (1-13) to circles containing letters of the alphabet (A-L) in alternating sequential order. A maximum of 300 seconds is allowed. Score ranges from 0-300. Higher score reflects poorer outcome.

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.

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)

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.

For each figure, one point is awarded to each satisfactory domain resulting in a maximum of 12-points per trial, for a total score ranging from 0-36, with a higher score reflecting a better outcome.

Trailmaking A is a psychological test with a score that is the number of seconds spent in connecting 25 numbered circles in sequential order. Score ranges from 0-150. Higher score reflects poorer outcome.

The GAD-7 questionnaire is used as a screening tool and severity measure for generalized anxiety disorder. The scale ranges from 0 - 21.

0-4 = normal 5-9 = mild 10-14 = moderate >15 = severe

The DTS is a 17-item self-reported measure that assesses the 17 Diagnostic and Statistical Manual IV (DSM-IV) symptoms of post-traumatic stress disorder (PTSD).

Items are rated on 5-point frequency (0 = "not at all" to 4 = "every day") and severity scales (0 = "not at all distressing" to 4 = "extremely distressing").

The DTS yields a frequency score (ranging from 0 to 68), severity score (ranging from 0 to 68), and total score (ranging from 0 to 136). The severity score will be used to assess this outcome.

The PSQI score scale ranges from 0-21. 0 = very good sleep quality 21 = very bad sleep quality A total score of "5" or greater is indicative of poor sleep quality (reflecting a higher level of fatigue)

The ESS is used to determine the level of daytime sleepiness. It is a questionnaire composed of 8 questions. The participant answers each question on a scale of 0 to 3 (0=no sleepiness, 1= mild sleepiness, 2= moderate sleepiness, 3= severe sleepiness). The total score is the sum of all responses for a maximum score of 24. A higher score reflects increased sleepiness.

MOCA is designed to assess cognitive impairment and Alzheimer's Disease. It is composed of the following:

Visuospatial and Executive Functioning: 5 points Animal Naming: 3 points Attention: 6 points Language: 3 points Abstraction: 2 points Delayed Recall (Short-term Memory): 5 points Orientation: 6 points Education Level: 1 point is added to the test-taker's score if he or she has 12 years or less of formal education.

Score ranges 0-31, with ≥ 26 being normal cognitive function. The lower the score, the greater the level of cognitive impairment.

The NBRS is a 28-item interview which includes a test of orientation and memory for recent events, questions regarding emotional state, post-concussional symptoms, focused attention, and concentration (performing serial sevens), explanation of proverbs, tasks of planning and mental flexibility, and delayed recall of three objects presented at the beginning of a session. Observations are also made regarding the patient's fatigability, visible signs of anxiety, disinhibition, agitation, hostility, difficulties in expressive and receptive communication, and disturbance of mood. The balance of the items are rated according to the patient's performance on brief tasks and quality of answers to interview questions. Each of the 28 items are scored on a scale of 0 (not severe) to 6 (extremely severe), for a maximum score of 168. A higher score reflects increased severity of neuropsychiatric symptoms.

Participants are asked to rate the severity of 16 different symptoms over the past 24 hours, on a severity scale from 0 to 4 (0 = not experienced, 1 = no more of a problem, 2 = mild problem, 3 = moderate problem, 4 = severe problem). The 16 symptoms include: headaches, dizziness, nausea and/or vomiting, hyperacusis, sleep disturbance, fatigue, being irritable, feeling depressed, feeling frustrated, forgetfulness, poor concentration, taking longer to think, blurred vision, light sensitivity, double vision, restlessness. Score ranges from 0 to 64, with a higher score reflecting increased severity of post-concussive symptoms.

The FSS is a 9-item questionnaire which measures the severity of fatigue and how it interferes with certain activities. The items are scored on a 7-point scale with 1=strongly disagree and 7=strongly agree. The score ranges from 9 to a maximum of 63. A higher score reflects greater fatigue severity.

MOAS measures four types of aggressive behavior as witnessed in the past week. Each section consists of five items, with the first section regarding verbal aggression, the second section focusing on aggression against property, the third section measuring autoaggression, and the fourth section concerning physical aggression. Participants are asked to check each item that is true over the last week. Items are allocated 0, 1, 2, 3 or 4 point(s), and then all points for each selected item are summed. The maximum total for each section is 10 if all items are selected. Total score ranges from 0-40 with a higher score indicating more aggressive behavior.

The SWL is a 7-point Likert-style response scale. The possible range of scores is 5-35, with a score of 20 representing a neutral point on the scale. Scores between 5-9 indicate the respondent is extremely dissatisfied with life, whereas scores between 31-35 indicate the respondent is extremely satisfied.

The STC reflects the level of social contact. The score ranges from 0-10, with 0= excellent contact, 10=no contact. A higher score reflects poorer social contact.
