A patient with a history of chronic alcohol use disorder is referred for neuropsychological evaluation. Which memory profile is MOST characteristic of Korsakoff syndrome?
Answer: Severe anterograde amnesia with relatively preserved remote memory and prominent confabulation
Korsakoff syndrome is characterized by profound anterograde amnesia, relative preservation of remote memories, and confabulation due to thiamine deficiency.
The Grooved Pegboard Test is used in neuropsychological assessment to evaluate:
Answer: Fine motor dexterity and psychomotor speed
The Grooved Pegboard measures fine motor dexterity and psychomotor speed by requiring precise placement of keyed pegs.
In assessing for dementia, a score of 20-25 on the Montreal Cognitive Assessment (MoCA) typically indicates:
Answer: Mild cognitive impairment (MCI) range
MoCA scores of 18-25 typically fall in the mild cognitive impairment range, while 26+ is considered normal cognition.
When evaluating attention with the Conners' Continuous Performance Test-3 (CPT-3), which measure BEST reflects sustained attention over the full test duration?
Answer: Detectability (d') over time-on-task blocks
Detectability (d') across time-on-task blocks on the CPT-3 captures the decline in signal detection over the test, reflecting sustained attention.
A neuropsychologist is assessing premorbid intellectual functioning in a patient with acquired brain injury. Which approach provides the MOST valid estimate of premorbid IQ?
Answer: Using word reading tests (e.g., TOPF, WRAT) combined with demographic variables
Word reading tests combined with demographic variables (the 'hold test' approach) provide the most valid premorbid IQ estimates because reading is relatively resistant to brain injury.
Which of the following is a TIER 1 (primary) performance validity test (PVT) commonly used in clinical neuropsychological practice?
Answer: Word Memory Test (WMT)
The Word Memory Test (WMT) is a well-validated, standalone forced-choice PVT with robust sensitivity and specificity for detecting invalid performance.
During a neuropsychological evaluation, a patient performs poorly on Trail Making Test Part B but normally on Part A. This dissociation MOST suggests impairment in:
Answer: Cognitive flexibility and set-shifting
Poor TMT-B with intact TMT-A isolates the cognitive flexibility and set-shifting demand added in Part B from the basic sequencing and motor speed in Part A.
