When Is Neuropsychological Evidence Essential in Personal Injury Claims?

In personal injury and clinical negligence litigation, cognitive and psychological consequences of injury are often central to causation, prognosis, and quantum. In many cases, instruction of a neuropsychologist is not merely helpful — it is essential.

This article outlines scenarios where neuropsychological evidence is critical, particularly in medicolegal cases across Devon and Cornwall.

Subtle Cognitive Deficits Following Injury

Clients may report difficulties with memory, attention, processing speed, or executive functioning that are not immediately obvious in everyday interactions. Neuropsychological assessment allows these subtle deficits to be objectively measured using standardised tools, providing evidence that cannot be obtained through clinical interview alone.

Mild Traumatic Brain Injury and Disputed Causation

In cases involving mild traumatic brain injury, symptoms are often:

• Subjective

• Inconsistent

• Challenged by defendants

A neuropsychologist can:

• Differentiate neurological impairment from psychological or situational factors

• Address symptom validity and effort

• Provide balanced, evidence-based conclusions suitable for court scrutiny

Pre-Existing Vulnerabilities and Complex Histories

Where a claimant has a history of learning difficulties, mental health problems, or prior injury, neuropsychological input is essential to:

• Establish baseline functioning

• Apportion causation

• Avoid over- or under-attribution of symptoms

Prognosis, Rehabilitation, and Future Needs

Neuropsychological evidence frequently informs:

• Long-term cognitive prognosis

• Rehabilitation recommendations

• Support and care planning

These opinions can significantly impact schedules of loss and settlement negotiations.

Why Early Instruction Matters

Delaying neuropsychological assessment may result in:

• Lost baseline information

• Increased diagnostic uncertainty

• Greater scope for challenge

Early instruction allows for clearer opinion formation and more robust reporting.
