mTBI Claims in Dispute: Dr Francesco Manfredonia Shares His Medico-Legal Expertise
Ardent Expert Chambers Member Dr Francesco Manfredonia, Consultant Neurologist, joined Ben Handy, Barrister at St John’s Chambers, for an INNEG webinar examining some of the most challenging issues arising in disputed mild traumatic brain injury (mTBI) cases.
Drawing on more than two decades of neurological experience, Dr Manfredonia explored the clinical grey areas that can make mTBI particularly difficult to assess, including normal imaging, persistent symptoms, uncertain causation and differing expert interpretations.
The session provided an opportunity to demonstrate the detailed neurological reasoning required when forming an independent medico-legal opinion in cases where the diagnosis or consequences of a brain injury remain contested.
Understanding the Clinical Grey Areas in mTBI
One of the central themes of Dr Manfredonia’s discussion was the difficulty of assessing cases that sit between clear structural brain injury and an apparently normal neurological investigation.
The term mild traumatic brain injury describes the severity of the initial injury rather than necessarily predicting the duration or significance of subsequent symptoms.
At the same time, persistent symptoms following an accident do not automatically establish ongoing structural brain injury.
For an expert witness, these cases therefore require careful analysis of the complete clinical picture, including the mechanism of injury, contemporaneous symptoms, neurological examination, medical records and the way symptoms develop over time.
Dr Manfredonia’s approach highlights the importance of resisting overly simplistic conclusions and considering whether the available evidence genuinely supports the proposed neurological diagnosis.
The Role and Limitations of Imaging
Neuroimaging formed another important part of the webinar.
Standard CT and MRI scans may appear normal following an mTBI, meaning imaging alone cannot always confirm or exclude the diagnosis.
Dr Manfredonia also discussed advanced techniques including diffusion tensor imaging (DTI) and susceptibility-weighted imaging (SWI), while emphasising the importance of interpreting any radiological findings within the wider clinical context.
For expert witnesses, imaging is one component of the evidence rather than a standalone answer.
Its significance must be assessed alongside the mechanism of trauma, clinical presentation, examination findings and subsequent course before conclusions are reached about injury or causation.
Looking Beyond the Scan
Dr Manfredonia also explored the importance of examining symptoms that may not be fully explained by conventional imaging.
Dizziness, balance disturbance, cognitive difficulty, headache and fatigue can all be reported following mTBI, but these symptoms may overlap with neurological, vestibular, psychological and other conditions.
This creates an important role for careful differential diagnosis.
An expert may need to determine whether the reported symptoms are neurologically consistent with the alleged injury, whether additional specialist assessment is required and whether alternative explanations need to be considered.
Dr Manfredonia’s discussion demonstrated why complex mTBI cases often depend on clinical interpretation rather than simply the presence or absence of an abnormal scan.
Diagnosis and Causation as Separate Questions
Another key theme was the distinction between diagnosis and causation.
An individual may experience genuine and persistent symptoms without those symptoms necessarily being attributable to the accident or injury under consideration.
For an independent expert, this requires consideration of the timing of symptoms, pre-existing factors, alternative explanations and whether the proposed mechanism is medically capable of producing the alleged consequences.
Where the medical records are limited or symptoms evolve over time, expert reasoning becomes particularly important.
The webinar illustrated the need to set out both the evidence supporting an opinion and the limitations or uncertainties that remain.
Managing Competing Expert Views
Disputed mTBI cases can also involve significant disagreement between experts.
Different interpretations may arise from the same clinical records, particularly where objective findings are limited and much of the assessment depends on reported symptoms, chronology and clinical judgement.
Dr Manfredonia’s contribution demonstrated the importance of explaining neurological reasoning clearly and transparently.
An effective medico-legal opinion should identify the evidence relied upon, distinguish established findings from areas of uncertainty and explain how alternative interpretations have been considered.
The discussion with Ben Handy also highlighted the value of experts communicating complex neurological issues in a way that remains clear and accessible within legal proceedings.
Specialist Expertise in Disputed Brain Injury
Dr Manfredonia is a Consultant Neurologist with more than two decades of clinical experience in the UK and Italy and has previously served as Clinical Director at Royal Wolverhampton NHS Trust.
His specialist interests include subtle and disputed traumatic brain injury, post-concussion symptomatology, imaging-negative presentations, vestibular dysfunction and complex neurological causation.
His work in disputed mTBI demonstrates the value of specialist neurological expertise in cases where the available evidence does not provide an obvious answer.
By examining the clinical history, mechanism of injury, neurological findings, imaging and symptom progression together, Dr Manfredonia is able to provide a balanced and evidence-led opinion on complex questions of diagnosis, causation and outcome.
