Managing MTBI-related Headaches With rTMS
Traumatic Brain Injury (TBI)
About this trial
This is an interventional treatment trial for Traumatic Brain Injury (TBI) focused on measuring TBI, traumatic brain injury, transcranial magnetic stimulation, headache
Eligibility Criteria
Inclusion Criteria:
- The following diagnostic criteria for MTBI based on the 1993 American Congress of Rehabilitation Medicine and recent recommendation from the DOD, and the current diagnostic criteria adopted by the VASDHS TBI Clinic will be used for the study. A traumatically induced physiological disruption of brain function, as manifested by at least one of the following:
- any loss of consciousness
- any loss of memory for events immediately before or after the accident
any alteration in mental state at the time of the accident, e.g.:
- feeling dazed
- disoriented
- confused)
Focal neurologic deficit (s) that may or may not be transient but where the severity of the injury does not exceed the following:
- loss of consciousness of approximately 30 min or less
- after 30 min, an initial Glasgow Coma Scale score of 13-15
- post-traumatic amnesia not greater than 24 hrs
In addition, the following established diagnostic criteria for " Persistent headache attributed to mild traumatic injury headache" based on the International Classification of Headache Disorder (ICHD-3) will be applied to the study subjects:
- A. Any headache fulfilling criteria C and D
- B. Traumatic injury to the head has occurred
- C. Headache is reported to have developed within 7 d after one of the following:
- 1. injury to the head
- 2. regaining of consciousness following the injury
- 3. discontinuation of medication(s) that impairs the ability to sense or report headache following the injury
- D. Headache persists for >3 mo after injury to the head
- E. Not better accounted for by another ICHD-3 diagnosis
Additional Inclusion Criteria:
- no prior experience of TMS treatment
- average persistent headache intensity more than 30 on the 0-100 mechanical visual analog scale(M-VAS) at the screening visit (visit 1) and average persistent headache intensity score greater than 3/10 on a numerical rating scale (NRS) reported in the headache diary (between visits 1&2)
- no history of daily persistent headache prior to the MTBI incidence
Exclusion Criteria:
- pregnancy; To be eligible for the study and to ensure no pregnancy risk, you will need to utilize contraception or practice abstinence until your study participation is completed
- history of pacemaker implant
any ferromagnetic material in the brain or body that would prohibit the patients from having a brain MRI, e.g.:
- bullet fragment
- shrapnel
- device implant
- history of dementia, major psychiatric or life threatening diseases
- presence of any other chronic neuropathic pain states;
- history of seizure
- pending litigation
- lack of ability to understand the experimental protocol and to adequately communicate in English
- history of chronic headache diagnoses such migraine, tension or cluster headaches prior to the incidence of MTBI.
- history of chronic headache prior to the MTBI incidence at a frequency more than once a month lasting more than one hour.
- evidence in the chart of recent exacerbation of depressive or anxiety symptoms, active substance dependence, suicidal intent or attempt within the previous month, and/or current psychotic symptoms

Arms of the Study
Arm 1
Arm 2
Experimental
Sham Comparator
Transcranial Magnetic Stimulation
Sham Transcranial Magnetic Stimulation
Active-repetitive transcranial magnetic stimulation (rTMS) at the left motor cortex.
Sham rTMS will consist of the same parameters as active, however, the subject will not receive the actual magnetic stimulation to the left motor cortex.
