    You are not alone

    Diffuse axonal injury is one of the most common types of head injury, diagnosed in around half of all severe head injury cases. It is also one of the most devastating. Patients with diffuse axonal injury or DAI invariably will suffer short-or long-term concussion; many will enter a coma. Approximately nine out of 10 patients with a severe DAI will not regain consciousness.

    If you have suffered diffuse axonal injury or any other type of brain injury at the fault of others, you may be entitled to compensation. Family may claim for compensation if the affected person is in a coma or has died.

    If you decide to make a diffuse axonal injury claim, your personal injury solicitor will take you through every step of the claims process. Your solicitor will be with you until you win your claim and get the compensation you deserve.

    Do I have a diffuse axonal injury claim?

    As a basic rule, you will be eligible to make an injury claim if you were injured:

    • within the last 3 years, and;
    • another person was to blame, and;
    • that person owed you a duty of care.

    Can I claim if I feel I was partly to blame?

    Identifying who is legally responsible for a claimant's injuries is not always obvious.

    In our 2023 Personal Injury Claimant Survey, 13.99% of respondents felt they were at least partly responsible for their accident or injuries.

    When fault on both sides caused a claimant's injuries, this is called 'contributory negligence'. In these situations, compensation may still be payable on the basis of a split liability agreement.

    How long do I have to claim diffuse axonal injury compensation?

    In most cases, you have 3 years from the date of your accident or injury.

    If you were injured when you were under 18, a parent, guardian or adult 'litigation friend' can make a claim on your behalf. Once you turn 18, you have until your 21st birthday to start an injury claim.

    How much compensation can I claim for a diffuse axonal injury?

    The amount of money you could claim for your injury will depend on:

    • the seriousness of your injury, and
    • any financial losses or costs you have incurred.

    At the start of your claim, your solicitor will consider the many ways your injuries have affected your life. Your solicitor will take these considerations into account to calculate the correct compensation award.

    What is diffuse axonal injury?

    Diffuse axonal injury occurs when the fibres that connect the cells in the brain are damaged or torn. This disrupts the electrical signals in the brain affecting movement, sensation, speech, memory and consciousness.

    The condition is known as "diffuse" axonal injury because, unlike most other brain injuries, a large area of the brain is affected. This means that the injury is difficult to diagnose and may be more severe than first appears on a conventional brain scan.

    What are the causes of diffuse axonal injury?

    DAI is caused by a sudden jolt to the brain within the skull. The skull itself is not fractured, but the violent jerking or shaking movement causes pressure to build up in the brain which, if not stabilised, can have severe or fatal consequences.

    The most common cause of a diffuse axonal injury is a high-impact road traffic accident. Other causes include falls from height, violent crime, sports injuries and shaken baby syndrome.

    It is also important to note that DAI can occur without a direct blow to the head occurring. Any hard or repeated shaking action may be enough to cause the brain to move back and forth in the skull.

    What are the symptoms of diffuse axonal injury?

    Symptoms range from mild to severe and include:

    • Long-term loss of consciousness
    • Temporary or repeated short-term loss of consciousness
    • Headaches
    • Dizziness and nausea.

    The type of symptoms will depend on the seriousness of the injury and the part of the brain that has been affected.

    Treatment and prognosis

    The immediate priority is to stabilise the injury and reduce the swelling of the brain. As with all brain injuries, early medical intervention is essential to prevent permanent loss of brain function and provide the best outcomes for the patient.

    In many cases, a full recovery is unlikely. It is not possible to surgically repair damaged or disconnected brain fibres, so the focus is on rehabilitation. Therapies may include physiotherapy, occupational therapy, speech therapy and counselling. Some patients may need to use mobility aids and other adaptive equipment to support their daily function.

    Compensation for diffuse axonal injury

    For the majority of patients, DAI is a life-changing condition. The level of brain damage associated with the injury usually makes it difficult for patients to return to work, and many will need 24-hour support and personal care.

    Often, occurrences of DAI are due to the negligence of other individuals or companies. If it can be shown that another person is legally responsible for the accident that caused the injury, a claim for compensation may be brought. Each case will be determined on its own merits by reference to the seriousness of the diffuse axon injury. However, due to the irrevocable nature of brain damage, the amount of compensation can be substantial.
