律师应在何时将当事人转介进行神经心理学评估？

Brain injuries and cognitive problems are often invisible in a legal file. A client can present well in a short meeting yet struggle with memory, planning or fatigue at work and at home. Knowing when to refer for a neuropsychological assessment can change how a matter is valued, managed and resolved.

This guide is for lawyers working in personal injury, workers compensation, TAC, CTP and related areas. It covers warning signs, timing, what to include in a referral, and how validity testing and expert duties apply.

What a neuropsychological assessment adds

A clinical neuropsychologist assesses how the brain is working through a structured interview, a review of records, and standardised tests of memory, attention, processing speed, language, visuospatial skills and executive functions (planning, reasoning and self-control). Results are compared with normative data for people of a similar age and, where relevant, education.

For a legal matter, the assessment can help answer questions about:

• the nature and severity of any cognitive impairment
• likely causes, including brain injury, psychological injury, pain, medication and pre-existing conditions
• estimated pre-injury ability, and how that compares with current functioning
• functional effects on work, study, daily living and relationships
• prognosis, treatment, rehabilitation and care needs
• decision-making capacity, where that is in question

Some schemes set requirements about who can provide the service. For example, the TAC’s psychology and neuropsychology policy requires neuropsychology to be provided by a psychologist with AHPRA endorsement as a clinical neuropsychologist.

Children and young people

Children’s brains are still developing, so the effects of an injury may only become clear as school demands increase. A child who seemed to recover well may later struggle with learning, attention or behaviour. For injured children, consider a paediatric neuropsychological assessment and a plan for review as they move through key school transitions.

Warning signs that suggest a referral

Injury factors

• a head strike, loss of consciousness, confusion at the scene or post-traumatic amnesia (a period of confusion and memory loss after injury)
• abnormal brain imaging, or a Glasgow Coma Scale score below 15 in ambulance or emergency records
• concussion with cognitive symptoms that persist. The 2023 international consensus on sport-related concussion describes symptoms lasting more than 4 weeks as persisting symptoms.
• other causes of brain injury, such as lack of oxygen, electrical injury, toxic exposure or stroke

A normal CT scan, or the absence of loss of consciousness, does not on its own rule out a brain injury that affects day-to-day functioning. Ambulance and emergency notes about confusion or memory gaps are often the most useful early evidence.

Client presentation

• forgetting instructions, repeating questions or losing track in meetings
• difficulty reading, understanding or organising documents
• marked fatigue, slowness or distractibility
• limited awareness of their own difficulties
• family reports of personality change, irritability or reduced initiative

Functional factors

• a failed or partial return to work or study
• new problems managing money, medicines, driving or household tasks
• psychological injury with prominent memory or concentration complaints, where the causes need to be separated

Scheme thresholds and capacity questions

Neuropsychological evidence is often relevant to scheme tests. Two examples:

• TAC serious injury (Victoria): the TAC’s serious injury fact sheet lists categories including serious long-term impairment or loss of a body function, and severe long-term mental or behavioural disturbance or disorder. Serious injury can also be established by a permanent impairment of 30% or more.
• NSW CTP: Part 6 of the Motor Accident Guidelines requires physical and psychological impairment to be assessed separately, and the ratings cannot be combined to exceed the 10% threshold for non-economic loss. Clear evidence separating cognitive effects of brain injury from psychological effects is valuable.

Capacity can also arise, for example capacity to give instructions, to settle, or to manage a compensation payment. A capacity assessment addresses the specific decision and the relevant legal test at the relevant time.

Getting the timing right

• Not too early: in the first weeks after a mild injury, results mostly reflect acute effects and may not predict longer-term outcomes.
• Not too late: an assessment can guide rehabilitation and return to work, and some benefits and claims have time limits.
• Serial assessment: a baseline assessment followed by a review can show recovery, stability or decline. That is often more informative than a single snapshot, especially for children and adolescents whose skills are still developing.
• Treatable factors first: where pain, sleep or mood problems are severe, it can help to address them, or at least document them, before a final opinion on permanent impairment.

Making a useful referral

Letter of instruction

Ask specific, answerable questions. Identify the legal tests, definitions or impairment guides the expert must apply, and any court practice note or expert code. Indicate whether a treating or independent opinion is sought.

Records to send

• ambulance, emergency and hospital records, including GCS scores, post-traumatic amnesia assessments and imaging
• rehabilitation, GP and specialist records after the injury
• pre-injury school reports, work history and performance reviews
• prior psychological, psychiatric, developmental or learning history
• earlier neuropsychological reports, so testing is not repeated unnecessarily
• relevant statements from the client and family

Preparing the client

Explain to the client why the assessment is being arranged, how long it may take and that breaks are available. Encourage them to bring glasses, hearing aids and a list of medicines, to sleep well beforehand, and to try their hardest on every task. Let the practice know about pain, fatigue or mobility needs so the day can be planned, and whether a support person will attend the interview.

Flag language, cultural, sensory or literacy needs early. An interpreter and culturally appropriate test selection affect how results can be interpreted.

Validity testing and expert duties

The American Academy of Clinical Neuropsychology’s 2021 consensus statement on validity assessment states that all clinical and forensic evaluations must proactively address whether test results are valid. Performance and symptom validity measures are routine. Invalid results do not by themselves establish malingering, and a careful expert considers the full range of explanations.

In court, a neuropsychologist acting as an expert witness is not an advocate. The Federal Court’s Expert Evidence Practice Note describes a paramount duty to assist the court impartially, overriding any duty to the party who retains the expert, and requires compliance with the Harmonised Expert Witness Code of Conduct. State courts and tribunals have their own codes. Our articles on expert witness duties 和 what makes a good medico-legal report cover this in more detail.
