NCT03642158

Brief Summary

A novel and promising therapy for cognitive dysfunction is non-invasive brain stimulation, of which transcranial magnetic stimulation (TMS) is a form. TMS is currently FDA-approved for use in depression and migraine. It is under investigation for use in a number of other neurologic and psychiatric disorders. In addition to its potential to improve affective symptoms, recent research has suggested that TMS targeted to select cortical regions can also improve cognition. In trials of TMS therapy for psychiatric disorders, several studies have shown benefits for cognitive function alongside symptom amelioration. In healthy persons, a course of stimulation of the parietal area improved objective measures of learning and memory. Among persons with TBI, there have been case reports supporting improvement in cognitive function and postconcussive symptoms; however, there have not yet been any controlled studies of TMS for TBI-related cognitive dysfunction.

Outcome Measures

Primary Outcomes (4)

  • Auditory target detection task

    subjects listen to a series of sounds, and will monitor for a specific sounds.

    10 minutes

  • Ruffs 2 and 7 selective attention test

    subjects must visually search for the numbers 2 and 7 among other distractors.

    ~5 minutes

  • DKEFS Verbal Fluency

    a measure of internal search and selection process, requires subject to generate several lists of items.

    10 minutes

  • California Verbal Learning Test II

    subjects are required to learn and recall an unfamiliar word list.

    10 minutes

Secondary Outcomes (1)

  • EEG

    10 minutes

Study Arms (2)

Active TMS

ACTIVE COMPARATOR

Subjects receive rTMS over the right DLPFC, in 2 second bursts at 10 Hz, followed by a 19 second break, for a total of 20 minutes. Stimulator intensity is set to 80% of motor threshold on day one, and 100% of motor threshold for the remainder of intervention. This paradigm is continued for 5 consecutive days.

Device: repetitive Transcranial Magnetic Stimulation

Sham TMS

SHAM COMPARATOR

Identical to active arm, but stimulator intensity is reduced to 30% of motor threshold, and the stimulator coil is oriented tangentially to the skull to "stimulate" air space above the head instead of cortical tissue.

Device: repetitive Transcranial Magnetic Stimulation

Interventions

repetitive Transcranial Magnetic Stimulation (rTMS) utilizes a magnetic coil of wire to non-invasively and painlessly activate small sections of the brain through the skull.
