Concussion after an accident: when a head injury has more serious consequences

A concussion may initially appear to be a relatively minor injury. Someone may hit their head in a fall, road traffic collision or workplace accident, attend hospital and return home expecting their symptoms to improve. 

In many cases, symptoms will improve with time. However, concussion is a form of temporary brain injury, and recovery is not always straightforward. How someone feels in the hours immediately after an accident may not always reflect the full impact the injury will have on them. Where a head injury proves more serious than first thought, we have specialist experience representing adults and children in serious and catastrophic brain injury claims. 

Knowing what to look out for, when to seek further medical advice and what support may be available can make an important difference. 

Why follow-up after a concussion matters 

Symptoms following concussion can include headaches, dizziness, nausea, fatigue, memory or concentration difficulties, balance problems and changes in mood or behaviour. For many people, these symptoms improve within a few weeks, but recovery can vary from person to person. 

Some of these symptoms may improve gradually. However, a head injury should not simply be forgotten once someone has left hospital or received an initial diagnosis. The NHS advises that someone recovering from a minor head injury should rest, avoid returning to work or school until they feel better, and avoid driving until they have fully recovered. 

If symptoms persist, worsen or new concerns develop, further medical advice should be sought. This gives healthcare professionals an opportunity to review the person's recovery and consider whether further investigation, treatment or specialist assessment is needed. The NHS recommends speaking to a GP if symptoms continue for more than two weeks, or if there is uncertainty about returning to work, education, driving or sport. 

Urgent medical attention is required where someone develops symptoms such as seizures, increasing drowsiness, weakness or numbness, problems speaking or walking, or difficulties with vision or hearing. Other warning signs can include loss of consciousness, problems with balance or understanding, clear fluid or bleeding from the ears or nose, or significant changes in behaviour. 

Having a follow-up with a medical professional also creates an opportunity for ongoing symptoms to be documented and, where necessary, for someone to be referred for further investigation, treatment or specialist rehabilitation.

When the effects are more serious than first thought 

For some people, the longer-term picture only becomes apparent as they try to return to everyday life. Difficulties may begin to affect work, education, relationships, decision making or the ability to live independently, even where the initial injury appeared relatively minor. 

Further medical assessment may also identify a more significant traumatic brain injury or confirm that ongoing symptoms are likely to require longer-term treatment, rehabilitation or support. 

Where the impact of the injury is greater than first expected, this can also change the legal position. If the accident was caused by somebody else's negligence, the claim may need to reflect not only the original injury, but the wider and longer-term effect it has had on the person's life and future. 

When could someone make a personal injury claim? 

At Simpson Millar, we support adults and children who have sustained brain injuries in circumstances including:

An injury alone does not mean there will automatically be grounds for a claim. It will generally be necessary to establish that another person or organisation was legally responsible for what happened. 

For example, if someone falls from height at work and sustains a brain injury, the circumstances may need to be investigated to establish whether the work was properly planned, the risks were appropriately assessed and suitable safety measures were provided. 

Similarly, following an accident in a public place, questions may arise about who was responsible for the premises, how the accident happened and whether reasonable steps should have been taken to prevent it. 

Importantly, the seriousness of a claim is not determined by the diagnosis someone receives immediately after the accident. If the longer-term consequences prove much greater than initially expected, the claim should reflect the actual effect the injury has had on that person's life and future. 

How Simpson Millar can help when a brain injury has lasting consequences 

Where a head injury results in significant or long-term difficulties, the legal claim can become much more complex. 

Our Serious Injury Solicitors look beyond the original diagnosis to understand how the injury affects the person's everyday life, independence and future. This can involve obtaining evidence from specialists in neurology, neuropsychology, rehabilitation, care, accommodation and other relevant areas. 

Where appropriate, we may also seek interim payments before the claim has concluded. These can help someone access rehabilitation, treatment, professional care or suitable accommodation at a time when that support can make a practical difference. 

Compensation in a claim can broadly include general damages and special damages. 

General damages compensate for the pain, suffering and loss of amenity caused by the injury. This considers the physical and psychological impact of the brain injury and the effect it has had on the person's ability to enjoy and participate in everyday life. 

Special damages compensate for the financial losses and expenses caused by the injury, which can include both losses already incurred and future needs. Depending on the circumstances, these may include:

  • Past and future loss of earnings
  • Loss of pension
  • Rehabilitation and treatment
  • Professional care and support
  • Case management
  • Adapted or alternative accommodation
  • Specialist equipment and assistive technology
  • Travel and other expenses resulting from the injury
  • Additional education or vocational support
  • Future care and assistance 

For someone facing the long-term effects of a brain injury, compensation can provide the financial security needed to put appropriate support in place and help maximise independence and quality of life. 

What if the medical care after the concussion was inadequate? 

When someone attends hospital following a head injury, the healthcare professionals treating them owe a duty to provide an appropriate standard of care. This includes properly assessing their symptoms and the circumstances of the injury, considering whether there are signs of a clinically important traumatic brain injury, and arranging further investigation, observation or treatment where this is clinically required. 

NICE guidance sets out specific factors that healthcare professionals should consider when deciding whether a CT scan is needed. These can include reduced consciousness, suspected skull fracture, seizures, neurological symptoms, repeated vomiting and, in some circumstances, factors such as age, bleeding or clotting disorders and the mechanism of the injury. 

Where someone does not require admission, appropriate discharge is also an important part of their care. NICE recommends that people discharged following a head injury are given verbal and written information explaining the nature of their injury, warning signs that should prompt a return to hospital, the possibility of delayed or persistent symptoms, and advice about returning to everyday activities. A suitable person should also normally be available to supervise them during the first 24 hours following the injury. 

Hospitals are also expected to communicate with the person's GP following an emergency department attendance for a head injury, and specialist referral may be considered where problems persist. 

Not every person attending hospital with concussion will require a CT scan, admission or specialist treatment. A poor outcome or missed diagnosis does not therefore automatically mean medical negligence occurred. 

However, there may be grounds to investigate where the care provided fell below a reasonable standard and this caused additional avoidable harm. For example, concerns may arise where:

  • recognised signs of a more serious traumatic brain injury were not appropriately assessed
  • CT imaging or other investigations were not arranged despite relevant clinical indications
  • deterioration or neurological symptoms were not acted upon
  • someone was discharged when further observation or treatment should reasonably have been considered
  • appropriate discharge or safety-netting advice was not provided
  • persistent symptoms were not appropriately reviewed or referred for specialist assessment 

Medical negligence claims usually require independent expert evidence to establish both that the care provided fell below the appropriate standard and that this made the person's eventual outcome worse than it otherwise would have been. 

When the accident and medical treatment both need investigating 

Sometimes there are two separate events to consider. 

For example, someone might sustain a head injury after falling at work because appropriate safety measures were not in place. The original accident could potentially form the basis of a personal injury claim. 

If that person then receives negligent medical care which causes additional avoidable brain injury or worsens their prognosis, there may also be a medical negligence claim. 

Distinguishing between the harm caused by the original accident and any additional harm caused by subsequent treatment can require detailed medical evidence. 

Our serious injury and medical negligence teams can work together in cases where these issues overlap, investigating the complete sequence of events and helping ensure the individual does not have to work out which type of legal claim applies before seeking advice. 

Support beyond the claim 

For people with more serious brain injuries, legal needs can extend beyond compensation. 

If an injury affects someone's ability to make particular decisions about their finances, our Court of Protection Solicitors can advise on Deputyships and the management of compensation awards. Where someone retains capacity, a Personal Injury Trust may help protect compensation when entitlement to certain means-tested benefits is assessed. 

Health and Welfare advice may also be needed where questions arise about capacity, care, treatment or where someone should live. 

For children and young people, an acquired brain injury can create new or significantly different educational needs. Our Education Law Solicitors can advise families on Special Educational Needs, Education, Health and Care Plans (EHCPs), SEND Tribunal appeals and securing suitable educational provision. 

This means that where the impact of a brain injury reaches into other areas of someone's life, specialist legal support is available to address those issues in their own right. 

Getting the right advice 

Where the effects of a head injury prove more significant than initially expected, understanding both the medical position and the legal options available can be important. 

At Simpson Millar, our serious injury and medical negligence teams can investigate how an injury happened, whether subsequent medical treatment caused additional avoidable harm, and the impact the injury is likely to have on the person's future. Where wider support is needed, our court of protection and education law specialists can also provide advice in their respective areas.
