Speech-language pathologists (SLPs) are integral to the comprehensive treatment of mild traumatic brain injury (mTBI), yet the evaluation and treatment options they offer may not be known to all primary care providers (PCPs). As the research on the management and treatment of mTBI continues to evolve, the PCPs role in referring patients with mTBI to the appropriate resources becomes imperative.
mTBI is a common injury in both military and civilian settings, but it can be difficult to diagnose and is not always well understood. Long-term debilitating effects have been associated with mTBI, with literature linking it to an increased risk of developing Alzheimer disease, motor neuron disease, and Parkinson disease.1 In addition, mTBI is a strong predictor for the development of posttraumatic stress disorder (PTSD). Among returning Iraq and Afghanistan service members, the incidence of mTBI associated mental health conditions have been reported to be as high as 22.8%, affecting > 320,000 veterans.2-5
The US Department of Veteran Affairs (VA) health care system offers these returning veterans a comprehensive, multidisciplinary treatment strategy. The care is often coordinated by the veteran’s patient aligned care team (PACT) that consists of a PCP, nurses, and a medical support associate. The US Department of Defense (DoD) and VA also facilitated the development of a clinical practice guideline (CPG) that can be used by the PACT and other health care providers to support evidence based patient-centered care. This CPG is extensive and has recommendations for evaluation and treatment of mTBI and the symptoms associated such as impaired memory and alterations in executive function.6
The following hypothetical case is based on an actual patient. This case illustrates the role of speech pathology in caring for patients with mTBI.
Case Presentation
A 25-year-old male combat veteran presented to his VA PACT team for a new patient visit. As part of the screening of his medical history, mTBI was fully defined for the patient to include “alteration” in consciousness. This reminded the patient of an injury that occurred 1 year prior to presentation during a routine convoy mission. He was riding in the back of a Humvee when it hit a large pothole slamming his head into the side of the vehicle. He reported that he felt “dazed and dizzy” with “ringing” in his ears immediately following the event, without an overt loss of consciousness. He was unable to seek medical attention secondary to the urgency of the convoy mission, so he “shook it off” and kept going. Later that week he noted headache and insomnia. He was seen and evaluated by his health care provider for insomnia, but when questioned he reported no head trauma as he had forgotten the incident. Upon follow-up with his PCP, he reported his headaches were manageable, and his insomnia was somewhat improved with recommended life-style modifications and good sleep hygiene.
He still had frequent headaches, dizziness, and some insomnia. However, his chief concern was that he was struggling with new schoolwork. He noted that he was a straight-A student prior to his military service. A review of his medical history in his medical chart showed that a previous PCP had treated his associated symptoms of insomnia and headache without improvement. In addition, he had recently been diagnosed with PTSD. As his symptoms had lasted > 90 days, not resolved with initial treatment in primary care, and were causing a significant impact on his activities of daily living, his PCP placed a consult to Speech Pathology for cognitive-linguistic assessment and treatment, if indicated, noting that he may have had a mTBI.6 Although not intended to be comprehensive, Table 1 describes several clinical areas where a speech pathology referral may be appropriate.
