When Does a Head Injury Claim Need a Neurologist?
A practical guide for solicitors on when symptoms after a head injury may justify an independent consultant neurological expert opinion.
Not every head injury claim needs a neurologist, but certain symptoms should prompt careful consideration.
In personal injury litigation, neurological expert evidence may be useful where there are persistent symptoms, uncertainty about causation, disputed prognosis or concern that a head injury has caused ongoing neurological impairment.
Why a neurological opinion may be needed
Head injury claims can involve symptoms that are difficult to interpret without specialist neurological assessment. A claimant may describe headache, dizziness, memory problems, concentration difficulty, fatigue, visual symptoms, balance disturbance, altered sensation or seizure-like episodes after an accident.
A neurological report can help clarify whether the symptoms are consistent with the reported injury, whether there is evidence of traumatic brain injury or concussion, whether further investigations are needed and what the likely prognosis may be.
The key medico-legal question is often not simply whether a head impact occurred, but whether the ongoing symptoms are neurologically consistent, accident-related and likely to persist.
Symptoms that may justify neurological expert opinion
Neurological input may be appropriate where the case involves one or more of the following:
- Loss of consciousness after the accident
- Post-traumatic amnesia or confusion
- Persistent headache or migraine-like symptoms
- Dizziness, imbalance or vestibular symptoms
- Memory, concentration or cognitive complaints
- Seizures or seizure-like episodes
- Altered sensation, weakness or limb symptoms
- Visual disturbance or neuro-ophthalmic symptoms
- Functional neurological symptoms
- A pre-existing neurological condition that may affect causation or prognosis
The presence of these symptoms does not automatically mean that the claim is neurological in nature. It does, however, suggest that a specialist opinion may help determine whether neurological injury, post-concussive symptoms, migraine, vestibular disturbance, functional symptoms or another explanation is more likely.
Evidence that can help the neurologist
A clear instruction and well-organised records can make a significant difference to the quality and efficiency of the report. Where available, solicitors should consider providing:
- The letter of instruction with specific neurological questions
- GP records before and after the accident
- Ambulance, emergency department and hospital records
- Imaging reports, including CT or MRI where performed
- Neurology, neuropsychology, ENT, vestibular or ophthalmology reports where relevant
- Medication history, especially headache, migraine or anti-seizure medication
- Occupational history and evidence of functional impact
- Previous expert reports and Part 35 questions where relevant
Causation and prognosis in head injury claims
In many cases, the neurological report will need to address whether the claimant's ongoing symptoms are likely to be caused by the accident, aggravated by it, unrelated to it or better explained by a pre-existing or alternative condition.
Prognosis is also important. Some post-concussive symptoms improve over time, while persistent headache, cognitive symptoms, dizziness or functional neurological symptoms may require more detailed assessment and treatment recommendations.
A consultant neurologist can also comment on whether further investigation, rehabilitation, medication review or referral to another specialist is appropriate.
When should solicitors instruct a neurologist?
Neurological opinion is often most useful when there is enough evidence to understand the clinical chronology, but before the case has become delayed by unresolved medical questions.
Solicitors may wish to consider instruction where symptoms are persistent, diagnosis is disputed, prognosis is unclear, causation is contested or a pre-existing neurological history may affect the analysis.
Early discussion may be helpful where there is uncertainty about whether a case requires a neurologist, a neuropsychologist, another specialist or no neurological expert evidence at that stage.
Next steps
Dr Adnan Al-Araji provides independent medico-legal neurology reports for personal injury claims involving head injury, concussion, post-traumatic headache, dizziness, seizures, functional neurological symptoms and related neurological issues.
Standard report turnaround is usually 4-6 weeks from receipt of the required documents and assessment details. Shorter timescales can be considered for urgent matters where possible.
