Understanding and Managing Sport-Related Concussion in Primary Care

The importance of the global emphasis on physical activity for health cannot be understated. However, it is crucial to address one of the adverse effects of contact sports—specifically, sport-related concussions. Sport-Related Concussion is a traumatic brain injury caused by a direct blow to the head, neck, or body resulting in an impulsive force being transmitted to the brain.

Sport-Related Concussion can present with a wide range of signs and symptoms, and can affect a person's thinking, concentration, memory, mood, and behaviour. These incidents are common and account for a significant number of emergency department visits. They also have some long-term risks, including cognitive and neurological problems.

Recent publications, like the consensus statement from the Concussion In Sport Group and the UK Government's landmark concussion guidance, offer valuable insights in the management of Sport-Related Concussion. This blog – based on our recent article in the British Journal of General Practice - aims to provide guidance on recognising, diagnosing, and managing Sport-Related Concussion within the context of primary care.

The Changing Landscape of Sport-Related Concussion

In 2016, over 1% of emergency department visits in England and Wales were attributed to concussions. Up to 60% of these involved children and adolescents. A 2021 UK House of Commons report criticised the current awareness level about Sport-Related Concussion in the UK’s NHS, indicating a need for better recording and treatment procedures.

Recognising Sport-Related Concussion

Symptoms of Sport-Related Concussion can range from cognitive issues to mood changes. Anyone with a suspected concussion should be immediately removed from the field of play and assessed by an appropriate healthcare professional within 24 hours of the injury. Those working in sport will be aware of specialist assessment tools pertaining to individual sports that aid clinicians when diagnosing concussion. The UK Government guidance provides a list of 'red flags' that require immediate assessment.

Once Sport-Related Concussion has been recognised or diagnosed, a short period (24–48 hours) of relative rest is advised, where only light-intensity physical activity that does not, or only minimally, exacerbates symptoms is undertaken. Subsequently, a logical graduated return to school/work and then sport can be started, where progression through stages is dependent on minimal and transient (the CSIG advise <1 hour) exacerbation of symptoms.

Sport-specific assessment tools exist for diagnosing concussion, such as the Sport Concussion Assessment Tool (SCAT6). These tools are most effective within 72 hours of the injury and evaluate symptoms, cognitive function, and coordination.

Managing Sport-Related Concussion in Primary Care

Primary care doctors play an essential role in managing Sport-Related Concussion. Initial management includes:

- Advising a short period of relative rest (24-48 hours)

- Reducing screen time and cognitive load

- No alcohol, solitary time, or driving within the first 24 hours

Patients with persistent symptoms beyond 28 days should be referred for a more comprehensive assessment. Gradual return to normal activities is advised, strictly adhering to symptom-dependent progress.

Challenges and Future Directions

The NHS's limited specialist services for treating complex or prolonged sport-related concussion symptoms create a care gap. This could be bridged by experts in sports medicine or primary care doctors with extended roles in sports medicine. Emerging technologies like Inertial Measurement Units (IMUs) in mouthguards and salivary micro-RNA samples show promise for better recognition and understanding of sport-related concussion.

Conclusions

Sport-Related Concussion is important. Effective recognition and management by general practitioners can significantly contribute to an individual’s immediate and long-term health. It is also vital for local commissioners to implement appropriate care pathways for managing this condition. By acknowledging the complexities in management and investing in ongoing research, we can create a healthcare system that supports both the benefits of physical activity and the challenges it can sometimes bring.

What is the difference between primordial prevention and primary prevention?

Primordial prevention and primary prevention are both crucial strategies for promoting health, but they operate at different levels. Primordial prevention aims to address the root causes of health problems and improve the wider determinants of health. It focuses on preventing the emergence of risk factors in the first place by tackling the underlying social, economic, and environmental determinants of health. This involves broad, population-wide interventions such as: Policies that promote healthy food choices: Think about initiatives like taxing sugary drinks to discourage unhealthy consumption, or providing subsidies for fruits and vegetables to make them more accessible. Urban planning that prioritises well-being: This could include creating walkable neighborhoods with safe cycling routes, ensuring access to green spaces for recreation and relaxation, and designing communities that foster social connections. Social programs that address inequality: Initiatives aimed at reducing pov...

What makes a good doctor – and who gets to decide?

What Makes a Good Doctor? This is the question that Waseem Jerjes and I explore in the Journal of the Royal Society of Medicine . It is a key question that underpins the architecture of medical education, clinical practice, regulation, and professional identity. It cannot be answered by regulators, educators, or employers in isolation. It must be answered together – by doctors and patients – revisited throughout a career, and adapted as society and the profession change. Without that shared reflection, the danger is not simply disillusionment, but the erosion of the moral foundations of clinical work. As we enter an era when diagnosis will increasingly involve artificial intelligence and when performance metrics reward volume over value, reclaiming this question as a professional one is imperative. The integrity of our institutions – and of the practitioners within them – depends on reimagining excellence in inclusive, relational terms. A good doctor is not a flawless technician or a f...

Relevance Over Recall: Rethinking How AI Uses Clinical Data

Our article in the Journal of the Royal Society of Medicine argues that safe and effective AI in healthcare must incorporate mechanisms that emulate human judgement - down-weighting old, inaccurate or superseded information and prioritising what is recent, clinically relevant and reaffirmed - so that AI supports, rather than disrupts, high-quality patient care.  Clinicians constantly revise, reinterpret and filter past information so that only what is relevant, accurate and timely shapes present-day management decisions; medical records function as dynamic “working tools” rather than fixed archives. By contrast, many AI systems lack this capacity for selective forgetting and often treat all historical data as equally meaningful.  This can lead to outdated or low-confidence diagnoses being repeatedly resurfaced, persistent labels influencing clinical expectations, and irrelevant, long-resolved events cluttering summaries and decision-support outputs. Such indiscriminate recall...
