Mild traumatic brain injury (mTBI), commonly referred to as concussion, constitutes a substantial proportion of head injuries seen in general practice and primary care settings. It is typically caused by a direct blow to the head or an indirect force that results in a rapid acceleration-deceleration of the brain within the skull. Although labelled as “mild”, such injuries can lead to a complex pathophysiological process affecting brain function, often without obvious structural damage detectable through routine imaging.
Family physicians play a critical role in recognising and managing mTBI, as they are often the first point of contact following injury. The diagnosis is primarily clinical and typically involves a transient alteration in mental status, which may include symptoms such as confusion, amnesia, headache, dizziness, fatigue, and sleep disturbances. Loss of consciousness is not required for the diagnosis, and many patients with mTBI never lose consciousness, making thorough evaluation paramount.
Understanding the typical symptom profile and recovery pattern of mTBI is essential for appropriate clinical management. While symptoms often resolve within days to weeks, a significant number of individuals experience persistent post-concussive symptoms that can interfere with their daily life and employment. Family physicians need to be aware of the variable presentation of mTBI and the psychosocial factors that may contribute to prolonged recovery.
Moreover, emerging evidence highlights the cumulative effects of repeated mTBI, particularly in populations such as athletes and military personnel, with potential links to long-term neurocognitive decline. This underscores the importance of accurate diagnosis and appropriate follow-up in primary care to prevent premature return to high-risk activities. Through a strong understanding of the condition, family physicians can provide both medical and educational support to patients and families, ensuring safe recovery and reducing the likelihood of complications.
Initial assessment and diagnosis in primary care
When a patient presents with suspected mild traumatic brain injury in general practice, a structured and thorough clinical assessment is essential. Family physicians begin by taking a complete history of the injury, including the mechanism of trauma, timing, and the presence or absence of symptoms such as headache, dizziness, confusion, memory loss, nausea, and visual disturbances. Particular attention should be paid to any loss of consciousness, however brief, and the duration of post-traumatic amnesia if present, as these factors can help grade the severity of the injury and inform decisions about further care.
Primary care practitioners rely on established clinical tools like the Glasgow Coma Scale (GCS) to assess the patient’s level of consciousness at presentation. Most patients with mTBI will have a GCS score of 13 to 15. Additional validated tools, such as the Standardised Assessment of Concussion (SAC) or the Sport Concussion Assessment Tool (SCAT), can be used to evaluate cognitive functioning, orientation, memory, and balance. These assessments are particularly useful in immediate post-injury evaluations and when managing athletes or other at-risk groups.
A physical examination should include a thorough neurological assessment, focusing on coordination, balance, eye movements, speech, and reflexes. Red flag symptoms—such as repeated vomiting, seizures, worsening headache, escalating confusion, or focal neurological deficits—warrant urgent referral for neuroimaging or specialist evaluation. In most cases of mTBI, however, neuroimaging such as CT scans is not routinely required, especially if the patient is stable and does not display high-risk features. This highlights the importance of clinical judgement in the primary care setting.
A key aspect of diagnosis in general practice involves the exclusion of more severe brain injuries and recognising when atypical features may indicate alternative diagnoses, such as cervical spine injury or intracranial haemorrhage. Family physicians must also assess for pre-existing conditions, including psychiatric or neurological disorders, which may complicate symptom interpretation and require tailored management.
In the early stages, it is also important to identify patients at risk of prolonged symptoms or poor recovery. Factors such as a history of previous mTBI, mental health issues, substance use, and strong expectations for rapid recovery can influence clinical outcomes. Recognising these during the initial assessment allows family physicians to plan appropriate follow-up and initiate early interventions to support recovery and prevent chronicity.
Family physicians in primary care settings play a pivotal role in the early recognition and diagnosis of mTBI. With an emphasis on clinical assessment over routine imaging, they ensure timely identification of the condition and guide patients through the initial stages of recovery while remaining alert to signs that warrant specialist referral.
Management strategies and patient education
Effective management of mTBI in general practice involves a patient-centred approach that integrates symptom monitoring, rest, gradual return to activity, and ongoing education. In the immediate aftermath of injury, family physicians should advise patients to take both cognitive and physical rest for 24 to 48 hours. This includes avoiding screen time, strenuous exercise, alcohol, and activities that require significant mental concentration. However, prolonged rest beyond this initial period may be counterproductive; thus, early mobilisation through light activity is recommended once symptoms begin to subside.
Clear guidance on the expected course of recovery is crucial. Family physicians play a key role in setting realistic expectations and helping patients understand that symptoms typically resolve within a few weeks. Education should also include warning signs that necessitate immediate medical attention, such as severe or worsening headache, repeated vomiting, seizure, or behavioural changes. Providing written information and resources on mTBI helps reinforce messages discussed during the consultation and can reduce anxiety stemming from uncertainty about the illness.
Gradual resumption of work, study, and recreational activities should be tailored to the individual’s symptom pattern and tolerance. In primary care, physicians may use a stepwise return-to-activity protocol, progressing from light aerobic exercise to full participation in pre-injury activities as tolerated. This is particularly important for athletes and individuals in high-risk occupations, where premature return could result in secondary injury and prolonged disability. In such cases, collaboration with occupational health services or sports medicine specialists may be beneficial.
Psychosocial support is another key aspect of mTBI management. Family physicians should be vigilant for signs of anxiety, irritability, sleep disturbance, or depression, which may not only complicate recovery but also indicate the need for psychological input. Normalising these symptoms as part of the recovery process, while remaining alert to persistent or worsening issues, can help patients feel supported and understood.
Providing reassurance while validating the patient’s experience is a delicate yet vital part of communication in general practice. Some individuals may struggle with the invisible nature of mTBI, especially in the absence of obvious abnormalities on imaging. In such cases, family physicians can act as advocates, ensuring that patients receive appropriate workplace accommodations or temporary adjustments to daily responsibilities to facilitate a safe recovery.
Where appropriate, discussions about injury prevention, particularly in populations at risk of recurrent mTBI such as athletes, should also be initiated. Advice regarding protective equipment, rule changes in sports, and awareness of symptoms fosters a proactive approach to managing future risk. For patients involved in contact sports, general practitioners may also liaise with coaches and training staff to ensure return-to-play protocols are properly implemented under medical supervision.
Ultimately, general practice offers an accessible and comprehensive setting for managing mTBI. With a multifaceted strategy that combines clinical oversight, patient education, and tailored activity plans, family physicians provide essential support in guiding patients through recovery while minimising the risk of persistent symptoms or complications.
Monitoring recovery and recognising complications
Ongoing monitoring of patients recovering from mTBI is a core responsibility in general practice, where family physicians are well positioned to provide longitudinal care and ensure appropriate follow-up. Given the variable nature of symptom evolution in mTBI, routine re-evaluations allow for tracking progress and identifying those not following the expected trajectory of recovery. Family physicians should schedule follow-up appointments within 1 to 2 weeks of the initial injury, with subsequent visits tailored to symptom persistence and the individual’s specific needs.
During recovery, common symptoms such as headaches, cognitive slowing, fatigue, and emotional lability may linger, and their resolution should be carefully monitored. Patients should be encouraged to report any new or worsening symptoms, particularly if affecting daily functioning or returning unexpectedly after improvement. Structured symptom checklists, including validated tools such as the Post-Concussion Symptom Scale (PCSS), can aid in documenting symptom trends and guiding both reassurance and intervention.
Recognition of post-concussion syndrome (PCS) is an important aspect of post-injury monitoring. This condition, characterised by the persistence of cognitive, physical, and emotional symptoms beyond the expected recovery period, affects a minority of patients but may considerably impact quality of life. Family physicians in primary care must distinguish normal variations in recovery from more concerning presentations that may signal PCS or alternative diagnoses, including mood disorders or underlying neurological conditions.
Red flag indicators that warrant prompt re-assessment or specialist input include escalating headaches, repeated episodes of vomiting, seizure activity, focal neurological signs, or significant changes in behaviour or cognition. Any such features should prompt consideration of further investigation, such as neuroimaging, and possible referral to neurology or neurosurgery services. Additionally, family physicians play a key role in screening for mental health comorbidities—such as depression, anxiety, or post-traumatic stress—which are commonly reported after mTBI and may intensify symptom burden or delay recovery.
In monitoring recovery, it is also important to be attuned to the psychosocial context of the patient. Pressures to return to work or sport prematurely may lead individuals to minimise symptoms, thereby increasing the risk of prolonged or worsened outcomes. General practice settings allow for development of trust and continued communication, supporting both patient honesty and shared decision-making regarding readiness to resume high-risk activities. Where necessary, family physicians can liaise with employers, schools or coaches to ensure that graduated return-to-activity protocols are respected.
Family physicians must maintain a low threshold for reassessing initial diagnoses if the clinical course deviates significantly from expectations. Alternative or compounding conditions—such as vestibular dysfunction, sleep disorders, or migraines—may account for ongoing symptoms and require distinct management strategies. Referrals to specialised services for neuropsychological evaluation, vestibular rehabilitation, or mental health support may be indicated in cases where recovery stagnates or functional limitations persist beyond the typical timeframe.
Through vigilant monitoring and early recognition of complications, family physicians ensure that patients recovering from mTBI receive personalised, proactive care that addresses both physical and psychological dimensions of recovery. The continuity of care found in general practice enables timely adaptation of treatment plans and referral where necessary, reducing the risk of persistent impairment and enhancing long-term outcomes.
Collaboration with specialists and referral pathways
Collaboration between family physicians and specialist services forms a critical component of comprehensive care for patients recovering from mTBI. While many cases can be effectively managed within general practice, the complexity and variability of symptoms mean that timely and appropriate referral pathways must be available when clinical progress is not as expected. Early identification of patients who may benefit from multidisciplinary input enhances outcomes and reduces the risk of chronic complications.
Family physicians in primary care are well positioned to coordinate access to specialist services, drawing on their holistic understanding of the patient’s health history and psychosocial context. Referral to neurology is often considered when there are persistent or unclear neurological symptoms, such as prolonged cognitive impairment, focal deficits, or recurrent headaches that do not respond to routine management. Referral may also be warranted where there is diagnostic uncertainty, particularly in ruling out structural brain pathology or identifying comorbid neurological disorders.
Neuropsychology input is especially valuable in patients presenting with lingering cognitive, behavioural, or emotional difficulties following mTBI. Specialist assessment provides objective evaluation of cognitive functioning and can help distinguish between post-concussive symptoms and underlying mental health issues or personality factors. In such cases, general practitioners play a key role in initiating referrals and supporting patient engagement with psychological services, ensuring they receive care tailored to both their cognitive needs and emotional wellbeing.
Additional referral options may include physiotherapy, particularly where vestibular dysfunction, balance issues, or neck pain are contributing to prolonged symptoms. Vestibular rehabilitation has demonstrated benefit in selected patients, and physical therapists with specialist training in concussion management can assist in reducing symptoms that impair day-to-day functioning and delay return to work or sport. Where such services are available locally, family physicians can expedite access by identifying suitable candidates early in the recovery pathway.
In adolescents and young adults with mTBI—particularly student athletes—coordination with paediatric specialists, sports medicine practitioners and school-based support services becomes important. General practice teams can facilitate the integration of medical recommendations within educational settings, ensuring that pupils receive temporary adjustments such as reduced workloads, extended deadlines, or access to quiet learning environments to support cognitive recovery. Special consideration should also be given to patients with learning difficulties or pre-existing mental health diagnoses, who may require broader multidisciplinary support during post-injury rehabilitation.
Throughout the management process, family physicians serve as central figures in guiding care coordination and ensuring that communication between services is efficient. This includes the timely transfer of relevant clinical information, updating specialists on patient progress, and integrating feedback from secondary care into ongoing treatment plans. General practice teams may also act as patient advocates, especially when navigating fragmented referral systems or addressing delays in accessing specialist input, thereby preserving continuity of care across settings.
In some cases, particularly those involving medicolegal implications such as motor vehicle accidents or employment-related injuries, patients may also require assessments by occupational health services or medico-legal professionals. Family physicians should be prepared to document recovery progress accurately, provide relevant reports, and liaise with insurers or legal representatives as needed. This administrative role, while secondary to clinical care, remains important in supporting the patient’s overall rehabilitation and access to necessary resources.
Ultimately, effective collaboration between primary care and specialist services ensures that patients recovering from mTBI receive timely, evidence-based, and individualised management. By recognising when to refer and maintaining active communication with external providers, family physicians play an essential role in coordinating care and optimising recovery outcomes across the healthcare continuum.
