    Neuropsychological testing value in MTBI

    Neuropsychological assessments help understand MTBI impacts by identifying limitations, preserved functions, strengths, and implications for daily life (e.g., work, education, independence).

    MTBI outcome factors

    MTBI outcomes stem from complex interplay of neurological, physical, and psychological factors. Lesion location doesn't always predict outcome, and psychological factors influence cognition.

    Influence of Fatigue on Cognition

    Fatigue from MTBI can significantly impact observed cognitive abilities and a person's self-perceived cognitive function, potentially leading to psychological distress, and impacting daily life.

    MTBI Outcome - Interaction

    Functional outcomes arise from the complex interaction of neurological, physical (such as fatigue and pain), and psychological factors (e.g., anxiety and motivation).

    Study Notes

    Neuropsychological Assessment

    • Neuropsychology is a sub-specialty of psychology focusing on brain-behavior relationships. Neuropsychological assessment primarily measures observable cognitive and intellectual functions as an output of brain activity.
    • Prior to advanced neuroimaging, neuropsychological assessment was key in determining if a brain deficit was organic (neurological) or functional (psychological). The assessment then localized areas of potential dysfunction within the brain.
    • Today, sophisticated instruments measure brain structure and activity. Common questions now include: what are the functional effects of known central nervous system damage?
    • Conditions leading to neuropsychological assessments include neurodevelopmental disorders (like intellectual disability and ADHD), traumatic brain injury (TBI), cerebrovascular disorders (strokes), brain tumors, dementia, and toxic effects (like alcohol exposure).

    Interaction of Factors Influencing Functional Outcome

    • Neurological, physical, and psychological factors significantly influence functional outcome.
    • Lesions in similar brain locations can result in varied outcomes.
    • Similar outcomes can result from lesions at varied locations.
    • Psychological conditions can manifest neurologically, and psychological factors influence cognitive function.
    • A model (Figure 1) shows how several factors influence functioning following mild traumatic brain injury (MTBI), including physical factors, neurological factors, and psychological factors.

    General Frameworks

    • Relevant neuropsychological functions include the assessment of: left and right hemispheres (e.g. generative, expressive, receptive).
    • Intellectual functions (e.g., general intellectual ability, and specific functions); and personality, affect, and behaviour which influence test output.
    • Possible assessment frameworks include: sensory reception, attention and concentration, memory and learning, language and linear thinking, visuospatial and holistic thinking, executive functions, organization and regulation of goal-directed behavior, motor output, learning, etc.

    Assessment Process

    • A comprehensive neuropsychological history includes current and past medical history, educational and occupational history, social history, family history, relationship status, use of substances, current medications, and more.
    • Initial symptom assessments can be structured using checklists.
    • Neuropsychological tests are often selected based on referral questions and assessment goals, considering the test-taker's age, language competence, testing conditions, and time constraints.
    • Different test categories may be used; including fixed or flexible batteries, to assess different cognitive domains (e.g., learning and memory, language/visuospatial functions, executive functions, and integrated skills).
    • Neuropsychological tests assess different functions, including tests for arousal/attention, sensory/motor functions, executive function, verbal reasoning and non-verbal reasoning. and visual memory
    • Examples of tests include: WAIS (Wechsler Adult Intelligence Scale), Repeating digit strings backward and arranging letter sequences, Conner's Continuous Performance Test (CPT), Stroop Color-Word Test, Bender Visual-Motor Gestalt Test, Wisconsin Card Sorting Test (WCST), among others.

    Non-verbal Reasoning Assessment

    • Visual/spatial tasks, such as assessing picture absurdities and other visual reasoning tasks, evaluate the test-taker's organizational tasks.

    Model of Memory Processes

    • Memory processes include external and internal sensory input, registration, encoding (conscious/unconscious, passive/active) in short-term memory, and the encoding of memories to long-term storage (e.g., declarative & procedural, episodic & semantic).
    • A model helps illustrate the process.

    Evaluation of Score Differences

    • Comparing scores to a normative sample allows for the assessment of whether levels of ability are average, below average, or above average.
    • Comparing test scores within the same individual (“within-individual comparisons”) helps measure changes associated with time or other interventions.
    • Evaluating possible differences between scores using a statistical method (e.g., standard error of difference, confidence level) distinguishes between true differences and differences simply due to test variations or measurement error. This allows better interpretation of performance.
