Explanation

Core Causes of Concussion

Concussion is a mild traumatic brain injury caused by a blow or jolt to the head, leading to temporary disruption of brain function.

It commonly occurs in sport, falls, or accidents and may not involve loss of consciousness.

Symptoms include headache, confusion, dizziness, memory disturbance, sensitivity to light or noise, and difficulty concentrating.

Recovery typically occurs over days to weeks, but some individuals develop persistent post-concussion symptoms requiring specialist care.

From a holistic perspective, recovery involves both neurological healing and careful management of cognitive, physical, and emotional load.

Why it happens

Possible causes & risk factors

Concussion usually comes from a mix of factors rather than a single cause. These are common contributors — not certainties.

Biology & temperament

The brain's soft tissue can be vulnerable to rotational and linear forces from impact, which may disrupt normal neural signaling and cellular function.

Stress & life events

High-stress environments such as competitive sports or high-risk occupations may increase exposure to situations where head impacts are more likely to occur.

Health & substances

A history of prior concussions, balance disorders, or certain neurological conditions may make the brain more susceptible to injury from repeated head trauma.

Sleep & lifestyle

Poor sleep prior to or following a head injury may slow the brain's natural recovery process and could heighten sensitivity to concussion-related symptoms.

What happens in the body

How this may affect the body

Concussion can involve several of the body’s systems. These are common patterns researchers describe — how they show up varies from person to person.

Brain & Nervous System

neurological

A sudden force may cause the brain to shift inside the skull, temporarily disrupting electrical signaling and triggering a neurochemical imbalance that affects cognition and coordination.

Cerebral Blood Flow

physiological

Following head trauma, blood flow regulation in the brain may become impaired, potentially contributing to headache, dizziness, and difficulty tolerating physical or mental exertion.

Autonomic Nervous System

neurological

The autonomic nervous system may become dysregulated after concussion, which can affect heart rate response, balance, and sensitivity to light and noise during recovery.

Cognitive & Emotional Processing

psychosocial

Disrupted neural activity following concussion may affect mood regulation, concentration, and sleep, with emotional and psychological stress potentially prolonging the recovery process.

Process

Diagnosis & Assessment

  1. Symptom history reviewA clinician asks about the mechanism of injury, timing of onset, and presence of symptoms such as headache, confusion, dizziness, nausea, or light sensitivity following the head impact.
  2. Neurological examinationA doctor evaluates balance, coordination, reflexes, pupil response, and cognitive function to identify signs of neurological disruption consistent with a concussion.
  3. Standardized concussion toolsTools such as the SCAT or ImPACT assessment may be used to evaluate memory, reaction time, and symptom severity, particularly in athletic or school settings.
  4. Imaging if red flags presentCT or MRI imaging may be ordered if a clinician suspects a more serious injury, such as bleeding or structural damage, based on symptom pattern or severity.

Management

Treatment & Management

Physical and cognitive rest

Initial rest from screens, reading, and strenuous activity is a standard first step some practitioners suggest to allow the brain time to recover after a concussion.

Graduated return-to-activity protocol

A structured, step-by-step return to school, work, and sport is widely used in sports medicine and may support safer recovery by reintroducing demands gradually.

Symptom-targeted medications

A doctor may discuss over-the-counter or prescription options to help manage headache, sleep disruption, or dizziness during recovery, tailored to each persons symptom profile.

Vestibular and vision rehabilitation

Specialized physical therapy targeting balance, eye tracking, and dizziness is something some practitioners suggest when those symptoms persist beyond the initial recovery window.

Mindfulness and stress reduction

Some people find that gentle mindfulness practices and relaxation techniques may support emotional regulation and reduce the cognitive fatigue that can accompany concussion recovery.

Self-Care

Lifestyle & Self-Care

Prioritize consistent, quality sleep

Sleep is when the brain does much of its recovery work. Some people find keeping a regular bedtime and limiting screens before bed may support healing after concussion.

Return to activity gradually

Jumping back into exercise or mentally demanding tasks too soon may slow recovery. A stepwise approach guided by a sports medicine professional is commonly recommended.

Limit cognitive overload early on

Reducing screen time, loud environments, and multitasking during early recovery may help ease symptoms like headache and light sensitivity for some individuals.

Eat a balanced, anti-inflammatory diet

A nutrient-rich diet with plenty of vegetables, healthy fats, and protein may support brain health during recovery. Some practitioners suggest reducing processed foods and added sugars.

Practice gentle stress reduction daily

Mindfulness, slow breathing, or light relaxation practices may help manage stress, which some people find worsens concussion symptoms like dizziness and cognitive fog.

The Evidence

Evidence context: Concussion

What research and clinical practice say about concussion recovery, and where complementary approaches may fit alongside standard care.

Overall pictureStrong evidence base

Concussion recovery is well-studied with clear clinical protocols

Graduated return-to-activity protocols are strongly supported by evidence and form the foundation of standard concussion care. Complementary approaches may support recovery alongside medical management, but professional assessment after any head injury is essential.

  • What the evidence showsStructured rest and graduated return protocols are the most well-supported approaches to concussion recovery.

    Strong evidence supports staged return-to-play and return-to-learn protocols, with cognitive and physical rest in the early phase followed by progressive activity. Persistent symptoms lasting beyond a few weeks may require multidisciplinary specialist input. Evidence for specific complementary approaches in concussion recovery is more limited and generally studied as adjuncts to standard care.

  • When to seek emergency careCertain symptoms after a head injury require immediate emergency assessment — do not wait.

    Seek emergency care immediately if there is loss of consciousness, repeated vomiting, a seizure, sudden vision loss, one pupil larger than the other, or slurred speech after a head impact. These may indicate a more serious injury beyond concussion. Any head injury should receive professional medical assessment, even when initial symptoms appear mild.

  • Standard clinical approachMedical assessment and structured rehabilitation are the cornerstones of concussion management.

    Clinical management typically involves initial rest, symptom monitoring, and a structured return to activity guided by a healthcare professional. Persistent post-concussion symptoms — including headache, cognitive difficulty, and mood changes — may require input from neurology, physiotherapy, or occupational therapy. Self-managing without professional guidance is not recommended after a head injury.

  • Complementary approaches in recoverySome complementary modalities are explored as supportive tools during concussion recovery, alongside standard care.

    Approaches such as physiotherapy, mindfulness, and gentle movement practices like yoga or tai chi may support symptom management and wellbeing during recovery. Neurofeedback is an emerging area with early-stage research interest. Evidence for most complementary approaches in concussion is limited, and none should replace professional medical assessment or structured rehabilitation protocols.

  • A whole-person view of recoveryConcussion recovery involves neurological healing alongside cognitive, physical, and emotional load management.

    Recovery is not purely physical. Disrupted sleep, mood changes, and difficulty concentrating are common and can interact with stress and daily demands. Managing cognitive and emotional load — not just physical activity — is recognised as important in recovery. A holistic approach considers all of these dimensions, ideally coordinated with a qualified healthcare provider.

  • What remains uncertainSome aspects of concussion recovery are still not fully understood, and individual outcomes vary.

    Why some people recover quickly while others develop persistent symptoms is not yet fully explained. Optimal management of post-concussion syndrome remains an active area of research. Evidence for many complementary interventions in this context is preliminary. Inflated outcome claims from any single approach should be viewed with caution, and ongoing symptoms warrant specialist evaluation.
