Immediate Actions After Suspecting a Concussion

A concussion is a traumatic brain injury that disrupts normal brain function, often caused by a blow to the head or body that results in rapid movement of the brain within the skull. Immediate and appropriate actions in the first 15 minutes following suspected concussion symptoms can prevent secondary injuries, such as cerebral edema or further bleeding, while ensuring the affected individual receives timely medical evaluation. This phase is critical for distinguishing between mild and severe cases, as well as determining the urgency of professional intervention.

The initial response involves a structured assessment of physical and cognitive symptoms, followed by a decision-making process to prioritize safety and medical care. Emergency responders, coaches, teachers, or bystanders must follow standardized protocols like the SCAT5 (Sport Concussion Assessment Tool 5) to evaluate the injury systematically. Concurrently, clear communication with the individual and, if possible, their guardians or colleagues is essential to mitigate risks such as exertion or exposure to hazardous environments.

Critical Steps Within the First 15 Minutes

The first 15 minutes after a suspected concussion are pivotal for assessing the severity of the injury and initiating appropriate care. These steps should focus on immobilization, symptom assessment, and decision-making for medical intervention. Failure to act promptly may exacerbate the injury, particularly in cases involving loss of consciousness, neurological deficits, or worsening symptoms.

Structured Checklist for Emergency Responders or Bystanders
The following table outlines a concise, actionable checklist to guide immediate response efforts. Each step is designed to ensure safety, gather critical information, and prepare for further medical evaluation.

Step Action Why It Matters Tools/Resources Needed
1 Ensure scene safety and immobilize the individual. Prevents further injury from movement, falls, or environmental hazards (e.g., heat, cold, or physical obstacles). First aid kit, cervical collar (if trained), gloves, emergency contact list.
2 Assess level of consciousness using the AVPU scale (Alert, Verbal, Pain, Unresponsive). Determines the severity of the brain injury and guides urgency of care. Unresponsive individuals require immediate emergency response. None (verbal cues sufficient).
3 Perform a rapid physical examination for signs of trauma (e.g., bleeding, bruising, deformities, pupil asymmetry). Identifies potential skull fractures, hemorrhages, or other life-threatening conditions that may require surgical intervention. Flashlight, gloves, penlight for pupil assessment.
4 Initiate the SCAT5 protocol to evaluate symptoms, cognition, and balance. Provides a standardized, evidence-based method to assess concussion severity and track progression. SCAT5 tool (printed or digital), stopwatch, balance assessment tools (e.g., foam pad).
5 Monitor for red flags indicating emergency care (e.g., vomiting, severe headache, slurred speech, weakness). Red flags signal potential secondary injuries (e.g., epidural hematoma) that require immediate medical attention. None (observational).
6 Instruct the individual to avoid movement, hydration, and stimulation (e.g., bright lights, loud noises). Reduces metabolic demand on the brain, lowering the risk of secondary complications. Water, dim lighting, quiet environment.
7 Document all observations (time of injury, symptoms, responses to questions) for medical professionals. Ensures continuity of care and accurate diagnosis by providing a clear history of events. Notepad, smartphone, or emergency medical form.

Application of the SCAT5 Protocol for Initial Evaluation

The Sport Concussion Assessment Tool 5 (SCAT5) is a widely adopted, standardized protocol for evaluating concussion symptoms in athletes and non-athletes alike. It consists of three primary components: symptom evaluation, cognitive assessment, and balance testing. The tool is designed to be administered by trained individuals within the first 15–30 minutes post-injury, though it may also be used for baseline comparisons in high-risk populations.

The SCAT5 protocol is divided into the following sections:

1. Symptom Evaluation
The individual is asked to self-report symptoms from a standardized list, including:

  • Physical symptoms: Headache, dizziness, nausea, blurred vision.
  • Cognitive symptoms: Confusion, memory problems, slowed thinking.
  • Emotional symptoms: Irritability, anxiety, sadness.
    • Symptoms are rated on a scale of 0 (none) to 6 (severe).
    Example: "On a scale of 0 to 6, how severe is your headache right now?"
    2. Cognitive Assessment
    This section evaluates memory, concentration, and processing speed through:
  • Standardized Assessment of Concussion (SAC): A series of questions testing orientation (e.g., "What month is it?"), immediate memory (e.g., repeating a list of words), and delayed recall.
  • Digit Span Test: Forward and backward repetition of digit sequences to assess working memory.
  • Symbol Matching: Timed task measuring processing speed and attention.

    • 3. Balance Testing
    The Balance Error Scoring System (BESS) is used to assess postural stability:

  • The individual stands in three stances (double-leg, single-leg, tandem) on two surfaces (firm ground, foam pad) for 20 seconds each.
  • Errors (e.g., stepping, raising arms for balance) are counted, with higher scores indicating greater instability.

    • Scoring and Interpretation

  • A total score is calculated by summing symptoms, cognitive errors, and balance errors.
  • Baseline comparisons (if available) help determine whether symptoms exceed pre-injury norms.
  • Severity classification:
  • Mild: SCAT5 score < 13, no red flags.
  • Moderate: SCAT5 score 13–24, persistent symptoms.
  • Severe: SCAT5 score > 24, red flags present (requires emergency care).

    • Instructions for Avoiding Movement or Activity

    Physical or cognitive exertion following a concussion can exacerbate brain swelling, delay recovery, and increase the risk of secondary injuries such as second impact syndrome (a rare but fatal condition where a second concussion occurs before the first has healed). Clear, authoritative communication is essential to ensure compliance with rest protocols.

    Script for Bystanders or Emergency Responders

    "[Name], you’ve experienced a possible concussion, and it’s critical that you stop all activity immediately—including physical movement, screen use, and mental exertion like reading or concentrating. Moving your head, playing sports, or even watching TV can make your brain injury worse. You must rest in a quiet, dimly lit place and avoid anything that causes discomfort or dizziness. Do not drive, operate machinery, or make important decisions until a medical professional clears you. If your symptoms worsen—such as severe headache, vomiting, or confusion—call emergency services right away."
    Key Points to Emphasize
  • Physical rest: No sports, exercise, or strenuous activities.
  • Cognitive rest: Avoid screens (TV, phones, computers), reading, or complex tasks.
  • Environmental control: Minimize noise, bright lights, and crowds.
  • Hydration: Encourage sips of water if the individual is conscious and not nauseous.
  • Monitoring: Instruct the individual to report any new or worsening symptoms immediately.

    • When to Call Emergency Services

    Not all concussions require emergency care, but certain "red flags" indicate life-threatening complications that necessitate immediate medical intervention. These symptoms often signal intracranial hemorrhage, cerebral edema, or other serious conditions that can progress rapidly. Recognizing these signs and acting promptly can prevent permanent disability or death.

    Medical Evaluation and Diagnostic Procedures for Concussion Assessment

    The accurate diagnosis of a concussion relies on a combination of clinical evaluation, symptom reporting, and specialized testing. While neuroimaging plays a limited role in initial concussion diagnosis, structured assessments—such as vestibular/ocular motor screening (VOMS) and cognitive testing—provide critical insights into functional impairments. Physicians integrate these findings with patient history and physical exams to determine the presence, severity, and underlying mechanisms of concussion-related dysfunction. The process emphasizes identifying red flags that may indicate more severe intracranial injuries requiring advanced imaging, ensuring timely and appropriate intervention.

    Standard Diagnostic Procedures in Concussion Assessment

    A concussion evaluation begins with a physical examination to assess general neurological function, including cranial nerve integrity, motor strength, and reflexes. The physician evaluates symptom severity using standardized tools like the Sport Concussion Assessment Tool (SCAT5) or the Child SCAT5, which quantify headaches, dizziness, nausea, and cognitive difficulties. Neurological tests focus on identifying focal deficits, such as asymmetrical reflexes, abnormal gait, or slurred speech, which may suggest complications like epidural hematoma or cerebral contusion.

    Imaging considerations are guided by clinical judgment rather than routine use. X-rays are typically excluded unless bony trauma (e.g., skull fractures) is suspected. Computed tomography (CT) scans are reserved for cases with red flags (detailed below) due to their ability to detect acute bleeding or structural abnormalities. However, CT scans have low sensitivity for concussion itself, as they cannot visualize diffuse axonal injury (DAI) or functional impairments. Magnetic resonance imaging (MRI)—particularly diffusion tensor imaging (DTI)—may reveal microstructural changes in white matter but is rarely used acutely due to cost, availability, and lack of immediate clinical impact. Functional MRI (fMRI) and positron emission tomography (PET) scans are experimental and not part of standard concussion protocols.

    Vestibular/Ocular Motor Screening (VOMS) Test Protocol

    VOMS is a five-station battery designed to identify vestibular and ocular motor dysfunction, common in concussions due to cervicogenic or brainstem involvement. The test evaluates symptom provocation during visually demanding tasks, correlating with balance and eye-tracking impairments. Each station is performed while the patient reports symptom severity (0–10 scale), with ≥50% symptom exacerbation considered clinically significant.

    1. Smooth Pursuits: The patient tracks a small target (e.g., pen) through horizontal, vertical, and diagonal paths at a controlled speed (e.g., 1 Hz). Impairments suggest cerebellar or brainstem dysfunction.
    2. Horizontal Saccades: The patient rapidly shifts gaze between two fixed targets (e.g., 10° apart) to assess saccadic accuracy and latency. Delayed or inaccurate saccades may indicate vestibular or frontal lobe involvement.
    3. Vertical Saccades: Similar to horizontal saccades but with upward/downward movements, highlighting midbrain or cerebellar pathology.
    4. Convergence: The patient focuses on a target moving from 16 inches to 4 inches away, testing near-point convergence. Failure to converge may reflect ocular motor or vestibular dysfunction.
    5. Visual Motion Sensitivity: The patient views a high-contrast, rotating pattern (e.g., spiral) for 30 seconds while reporting symptoms. Photophobia or dizziness suggests vestibular or visual processing deficits.

    VOMS results guide rehabilitation strategies, such as vestibular rehabilitation therapy (VRT) or visual therapy, and inform return-to-play decisions. A positive VOMS (symptom exacerbation ≥50%) correlates with prolonged recovery and higher risk of post-concussion syndrome.

    Red Flags Warranting Advanced Imaging

    Immediate CT or MRI is indicated when clinical signs suggest intracranial hemorrhage, skull fracture, or mass effect. The following table categorizes red flags by severity, recommended action, and timeframe for concern, based on CDC and AAN guidelines:
    Symptom Severity Level Recommended Action Timeframe for Concern
    Glasgow Coma Scale (GCS) ≤14 High Emergency CT scan; neurosurgical consultation Immediate (within 1 hour)
    Focal neurological deficits (e.g., hemiparesis, aphasia) High CT scan; rule out stroke or contusion Immediate (within 1 hour)
    Seizure or post-traumatic seizure High CT scan; antiepileptic prophylaxis if indicated Immediate (within 1 hour)
    Worsening headache (described as "the worst of my life") High CT scan; rule out epidural/subdural hematoma Immediate (within 1 hour)
    Repeated vomiting (>2 episodes) Moderate-High CT scan if persistent beyond 6 hours 6–12 hours post-injury
    Amnesia >30 minutes post-injury Moderate CT scan if associated with other red flags Within 24 hours
    Retrograde or anterograde amnesia Moderate Baseline neurocognitive testing; monitor for delayed symptoms Within 72 hours
    Balance or coordination deficits (e.g., ataxia) Moderate VOMS; consider MRI if persistent >7 days 48–72 hours post-injury
    Progressive confusion or disorientation Moderate-High Repeat CT if no improvement in 24 hours 24–48 hours
    Key Note: In children <2 years old or adults >65 years, lower thresholds for imaging apply due to higher risk of skull fractures or intracranial bleeds.

    Cognitive Testing Tools in Concussion Assessment

    Computerized neurocognitive testing (CNT) provides baseline and post-injury comparisons to quantify cognitive impairments. The most widely used tools include:

    - Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT): A 20–30-minute battery assessing memory, processing speed, reaction time, and attention. Scores are compared to pre-injury baselines (if available) or normative databases. Limitations include:

  • False positives in fatigued or anxious patients.
  • False negatives in mild concussions with normal test results but persistent symptoms.
  • Learning effects (improved performance on retesting without injury).
  • Cultural and linguistic biases in normative data.

    • - King-Devick (K-D) Test: A rapid, sideline-friendly assessment measuring ocular motor control and cognitive processing. The test involves:
    1. Reading a sequence of numbers aloud.
    2. Recording time to completion and errors.
    A ≥20% increase in time or ≥3 errors suggests concussion-related dysfunction. Advantages include high sensitivity for concussion (85–90%) and short administration time (<2 minutes). Limitations include:

  • False positives in patients with dyslexia or visual impairments.
  • Limited specificity for differentiating concussion from other conditions (e.g., migraines).

    • CNT should not replace clinical judgment but complements symptom reporting and VOMS findings to guide management.

    When to Repeat Diagnostic Testing
    Diagnostic retesting is considered only after symptom resolution or

    Symptom Management and Recovery Strategies for Concussion

    Effective management of concussion symptoms requires a structured, phase-specific approach tailored to the individual’s physiological and cognitive recovery needs. Symptoms vary widely in severity and duration, necessitating a combination of rest, symptom tracking, and gradual reintroduction of activities to prevent complications such as post-concussion syndrome (PCS). This section outlines evidence-based strategies for acute, subacute, and long-term recovery, including non-pharmacological interventions, medication considerations, and specialized therapies like vestibular and vision rehabilitation.

    Timeline for Symptom Management and Recovery Phases

    Concussion recovery is divided into three distinct phases, each requiring targeted interventions to optimize healing and minimize symptom exacerbation. The following table summarizes the typical duration, common symptoms, management priorities, and activities to avoid during each phase.
    Phase Common Symptoms Management Focus Avoidance Strategies
    Acute Phase (0–72 hours)
    • Headache (often severe)
    • Dizziness/vertigo
    • Nausea/vomiting
    • Confusion or disorientation
    • Sensitivity to light/noise
    • Fatigue or sleep disturbances
    • Absolute rest (physical and cognitive)
    • Hydration (2–3L water/day) to reduce headache severity
    • Dark, quiet environment to minimize sensory overload
    • Short, frequent naps (10–20 minutes) to avoid sleep deprivation
    • Monitor for worsening symptoms (e.g., neck stiffness, slurred speech)
    • Strenuous physical activity (e.g., sports, weightlifting)
    • Screen time (phones, TV, computers) beyond 20 minutes/day
    • Alcohol or caffeine (can exacerbate dehydration and headaches)
    • Driving or operating machinery
    Subacute Phase (3–10 days)
    • Persistent headache (mild to moderate)
    • Balance difficulties (e.g., unsteadiness)
    • Memory/concentration problems ("brain fog")
    • Irritability or emotional lability
    • Photophobia or phonophobia (mild)
    • Gradual increase in cognitive activity (e.g., reading, puzzles)
    • Introduction of light aerobic exercise (e.g., walking, swimming)
    • Sleep hygiene optimization (consistent bedtime, dark/cool room)
    • Stress reduction techniques (e.g., deep breathing, meditation)
    • Vestibular and vision therapy referral if symptoms persist
    • Contact sports or high-impact activities
    • Overworking mentally (e.g., exams, complex tasks)
    • Excessive screen time (symptoms often worsen with eye strain)
    • Isolation (social interaction can improve mood and recovery)
    Recovery Phase (Weeks to Months)
    • Residual cognitive fatigue
    • Occasional dizziness with movement
    • Sleep disturbances (insomnia or hypersomnia)
    • Emotional sensitivity (e.g., frustration, anxiety)
    • Persistent headaches (in ~10% of cases)
    • Gradual return to work/school with accommodations (e.g., reduced hours, flexible deadlines)
    • Cardiovascular conditioning (e.g., cycling, elliptical)
    • Cognitive rehabilitation (e.g., neurofeedback, memory exercises)
    • Mental health support (e.g., therapy for anxiety/depression)
    • Long-term symptom tracking to identify patterns
    • Returning to contact sports before medical clearance
    • Ignoring persistent symptoms (e.g., "pushing through" fatigue)
    • Sudden increases in physical or cognitive demands
    • Substance use (e.g., opioids, benzodiazepines, which may mask symptoms)
    Note: Recovery timelines vary significantly; ~80% of individuals recover within 3–4 weeks, while 10–15% experience prolonged symptoms (>3 months). Factors such as age, prior concussions, and comorbidities (e.g., migraines, ADHD) influence duration.

    Non-Pharmacological Treatments for Concussion Symptoms

    Non-pharmacological interventions are the cornerstone of concussion management, as they address symptoms without the risks of medication side effects or interactions. The following strategies are supported by clinical guidelines and patient-reported outcomes.

    Hydration for Headache Management

    Dehydration exacerbates headaches and cognitive fatigue by reducing cerebral blood flow. Actionable steps include:
  • Daily fluid intake: Aim for 30–35 mL/kg body weight (e.g., 2.1L for a 70kg individual). Use a marked water bottle or app (e.g., Hydro Coach) for tracking.
  • Electrolyte balance: Include potassium-rich foods (bananas, spinach) and sodium (coconut water, broth) if sweating excessively.
  • Avoid diuretics: Limit caffeine (coffee, tea, energy drinks) and alcohol, which increase fluid loss.

    • Sleep Hygiene for Fatigue and Cognitive Recovery

    Sleep deprivation prolongs recovery by impairing neuroplasticity and memory consolidation. Implement these evidence-based practices:
  • Consistent sleep schedule: Maintain a regular bedtime/wake time (even on weekends) to regulate circadian rhythms.
  • Optimized sleep environment:
  • Temperature: 18–22°C (64–72°F) for melatonin production.
  • Light: Use blackout curtains or a sleep mask to block light; avoid screens 1 hour before bed.
  • Noise: White noise machines or earplugs to mask disruptions.
  • Nap strategies: Limit naps to 10–20 minutes to avoid sleep inertia (grogginess). Avoid napping after 3 PM to prevent nighttime insomnia.
  • Relaxation techniques: Progressive muscle relaxation or guided meditation (apps like Headspace or Calm) to reduce pre-sleep anxiety.

    • Cognitive Rest to Reduce Brain Fog

    Excessive mental exertion can worsen symptoms. Structured cognitive rest includes:
  • Screen time limits: Reduce digital devices to ≤20 minutes/day during the acute phase. Use blue-light filters (e.g., f.lux) if necessary.
  • Gradual reintroduction: Increase cognitive load by 10–20% per day (e.g., reading for 5 minutes → 10 minutes).
  • Multitasking avoidance: Focus on single-task activities (e.g., listening to a podcast without reading).
  • Memory aids: Use sticky notes, voice memos, or planners to compensate for short-term memory gaps.

    • Dietary and Environmental Modifications

  • Anti-inflammatory diet: Prioritize omega-3s (fatty fish, flaxseeds), antioxidants (berries, leafy greens), and magnesium (nuts, whole grains) to reduce neuroinflammation.
  • Sensory management:

    Managing a concussion effectively hinges on a combination of timely intervention, accurate diagnosis, and disciplined recovery protocols. From the moment symptoms emerge, every action—whether assessing cognitive function, monitoring physical responses, or adjusting activity levels—plays a role in determining the trajectory of healing. By leveraging standardized tools, clinical judgment, and personalized care plans, individuals can navigate the recovery process with confidence. Ultimately, awareness and preparedness are the cornerstones of minimizing concussion-related risks and fostering a full return to daily life or athletic pursuits.

    • FAQ

    What should I do if someone gets a concussion and I need to treat it at home?

    Rest in a quiet, dimly lit space for 24–48 hours, avoid screens, and take over-the-counter pain relievers like ibuprofen (if approved by a doctor) for discomfort. Stay hydrated, avoid caffeine/alcohol, and wake every 2–3 hours to check for worsening symptoms like confusion or vomiting. Do not return to work/school or sports until cleared by a healthcare provider.

    How do you properly care for a child who has a concussion?

    Keep the child awake and monitor closely for 24 hours, ensuring they rest in a quiet environment without screens. Limit physical and cognitive activity (e.g., no schoolwork or sports) for at least 2–3 days, and watch for symptoms like irritability, nausea, or balance issues. Follow up with a pediatrician within 24–48 hours, especially if symptoms worsen or persist beyond a week.

    What helps relieve a headache caused by a concussion?

    Rest in a cool, dark room and apply a cold compress to your forehead or neck for relief. Over-the-counter pain meds like acetaminophen (avoid ibuprofen/aspirin if advised against) may help, but consult a doctor first. Stay hydrated and avoid triggers like bright lights or loud noises, which can worsen symptoms.

    What immediate steps should I take if my toddler has a concussion?

    Call a doctor or seek emergency care if the toddler lost consciousness, has repeated vomiting, or shows confusion. Keep them awake and limit stimulation (no screens or loud noises), and avoid putting them to sleep if they’re hard to rouse. Watch for signs like extreme fussiness, seizures, or difficulty walking, which require urgent medical attention.

    What’s the best way to recover from a concussion as an adult?

    Gradually reintroduce physical and mental activities over days to weeks, starting with light tasks (e.g., short walks) and avoiding anything that causes dizziness or headaches. Follow a doctor’s guidance on return-to-work/sports protocols, and prioritize sleep, hydration, and stress reduction. Avoid alcohol, caffeine, and secondhand smoke, which can delay healing.

    How long does it take for a teenager to recover from a concussion?

    Most teens recover in 1–4 weeks, but symptoms like headaches or fatigue can linger for months in some cases. Follow a step-by-step return-to-activity plan (approved by a doctor) to avoid reinjury, and avoid screens/sports until symptoms fully resolve. Seek medical help if symptoms worsen or last beyond 4 weeks.
