SCOPE: Evaluation and management of persistent symptoms following mild traumatic brain injury (mTBI) or concussion in adults, defined as symptom persistence beyond 3 months from injury. Covers symptom-specific pharmacologic management (headache, dizziness, cognitive dysfunction, sleep disturbance, mood changes), vestibular rehabilitation, cognitive rehabilitation, graded return-to-activity protocols, neuropsychological testing, and mental health screening/treatment. Applicable primarily in outpatient setting with ED and inpatient considerations for acute re-evaluation. Excludes acute concussion management (first 0-4 weeks), moderate-severe TBI, pediatric concussion, and sports-specific return-to-play protocols.


DEFINITIONS: - Concussion / Mild TBI: Traumatically induced transient disturbance of brain function; GCS 13-15, LOC <30 minutes, PTA <24 hours - Post-Concussion Syndrome (PCS): Persistence of 3 or more concussion symptoms (headache, dizziness, fatigue, irritability, insomnia, concentration/memory difficulty) for >3 months after mTBI - Post-Traumatic Headache (PTH): Headache developing within 7 days of head injury or regaining consciousness after injury; persistent if >3 months - Persistent Post-Concussive Symptoms (PPCS): Current preferred terminology for symptoms lasting beyond expected recovery window (>4 weeks to 3 months) - Post-Traumatic Vestibular Dysfunction: Dizziness and balance impairment following TBI, may include BPPV, vestibular hypofunction, or central vestibular dysfunction - Cognitive Fatigue: Disproportionate mental exhaustion with cognitive effort, common in PCS

Subdural hematoma (chronic) Progressive headache, cognitive decline, focal deficits; risk with anticoagulation, elderly, falls CT head, MRI brain
Depression / Anxiety disorder Mood symptoms predate injury or disproportionate to injury severity; lack of cognitive deficits on testing PHQ-9, GAD-7, neuropsychological testing
PTSD (Post-traumatic stress disorder) Re-experiencing trauma, avoidance, hyperarousal; nightmares; may overlap significantly with PCS PCL-5, psychiatric evaluation
Post-traumatic hypopituitarism Fatigue, weight changes, hyponatremia, sexual dysfunction; can present months after TBI Pituitary hormones (cortisol, TSH, IGF-1, testosterone)
Sleep apnea (new or worsened post-TBI) Excessive daytime sleepiness, snoring, witnessed apneas, morning headache Polysomnography
Benign paroxysmal positional vertigo (BPPV) Positional vertigo (brief episodes), positive Dix-Hallpike Dix-Hallpike maneuver, VNG

Whiplash-associated disorder Neck pain predominant, limited ROM, no LOC at injury Cervical imaging, clinical exam
Idiopathic intracranial hypertension Headache with papilledema, visual obscurations, pulsatile tinnitus Fundoscopy, LP with opening pressure, MRV
CNS infection Fever, meningismus, progressive course CBC, LP, MRI with contrast
Malingering / Symptom exaggeration Medicolegal context, inconsistent performance, effort testing failure Neuropsychological testing with embedded/stand-alone effort measures
Normal aging / Pre-existing cognitive impairment Cognitive symptoms predate injury; stable rather than post-injury onset Pre-injury cognitive testing, collateral history

NOTES

  • Post-concussion syndrome is a clinical diagnosis; neuroimaging is often normal and does not rule out PCS
  • Most patients recover within 3 months; 15-30% develop persistent symptoms
  • Avoid prolonged cognitive and physical rest beyond 24-48 hours acutely — this may worsen outcomes
  • Graded aerobic exercise (sub-symptom threshold) is the strongest evidence-based intervention for PCS recovery
  • Post-traumatic headache is the most common symptom; treat with migraine prevention paradigm (amitriptyline first-line)
  • Avoid topiramate as first-line in PCS due to cognitive side effects that may worsen PCS-related cognitive impairment
  • Avoid chronic benzodiazepine use — impairs vestibular compensation and cognitive recovery
  • Screen all PCS patients for depression, anxiety, and PTSD at each visit (PHQ-9, GAD-7, PCL-5)
  • Post-traumatic hypopituitarism is underdiagnosed; screen with morning cortisol, TSH, IGF-1 if persistent fatigue
  • Vestibular symptoms (dizziness, balance problems) respond well to targeted vestibular rehabilitation
  • Cognitive symptoms correlate poorly with injury severity; neuropsychological testing provides objective measurement
  • Multidisciplinary approach (neurology, neuropsychology, PT, OT, SLP, psychology) yields best outcomes
  • Consider cervicogenic headache as co-contributor; whiplash and concussion frequently co-occur
  • Secondary gain and medicolegal context do not preclude genuine symptoms but should be noted
  • Effort testing during neuropsychological evaluation is standard to ensure valid results
