Timing Matters: When Should a Solicitor Instruct a Neuropsychologist in Devon and Cornwall?

The timing of expert instruction can significantly influence the strength and usefulness of neuropsychological evidence. In some cases, there is a delay instructing a neuropsychologist until difficulties become unavoidable — often to the detriment of the claim.

This article considers when neuropsychological instruction is most effective in medicolegal proceedings.

Early Instruction: Advantages and Considerations

Early instruction allows:

• Establishment of baseline functioning

• Identification of genuine cognitive deficits

• Early guidance on rehabilitation and prognosis

It also reduces reliance on retrospective reconstruction of symptoms, which can be problematic under cross-examination.

Risks of Delayed Instruction

Late instruction may result in:

• Loss of contemporaneous evidence

• Greater diagnostic uncertainty

• Increased scope for dispute

• Reduced clarity on causation

These issues are particularly relevant in mild traumatic brain injury and disputed cognitive claims.

Balancing Proportionality and Evidential Value

Solicitors must consider proportionality, but neuropsychological evidence is often more cost-effective when obtained early, as it:

• Narrows issues in dispute

• Informs litigation strategy

• Reduces the likelihood of competing expert opinions

Case Complexity as a Guide

Early instruction is particularly advisable where:

• Cognitive symptoms are subtle or evolving

• There are pre-existing vulnerabilities

• Symptom validity may be challenged

• Capacity issues are anticipated

Regional Practicalities

In Devon and Cornwall, early planning is essential to avoid delays associated with specialist availability and to ensure assessments occur at an appropriate stage in proceedings.

Timing is a strategic decision, not an administrative one. Solicitors who instruct a medicolegal neuropsychologist early are better positioned to secure clear, defensible evidence and to manage cases efficiently from the outset.
