OBJECTIVE: Anti N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is an autoimmune disorder that was only fully discovered recently and neuropsychological outcome data remains sparse. We present the case of BA, a 19-year-old male, which illustrates the cognitive outcome in an untreated case over a time period of over 2½ years. METHOD: We conducted three cognitive assessments, including tests of memory and executive functioning, over this time period and considered the evidence for reliable change in memory function using the Wechsler Advanced Clinical Solutions (ACS) serial assessment package...

OBJECTIVE: The Paced Auditory Serial Addition Test (PASAT) is frequently employed to measure executive functions in patients with Multiple Sclerosis (MS). In the past, the PASAT has often been criticized because of its stressful and demanding requirements. Continuous utilization might also reduce its validity. The Five-Point Test (FPT) by Regard, Strauss, and Knapp ((1982) Children's production on verbal and non-verbal fluency tasks. Perceptual and Motor Skills, 55, 839-844.) is a short test of figural fluency which might serve as a substitute...

OBJECTIVE: Children delivered at the edge of viability are at greatest risk of medical and neuropsychological disability, their adverse outcomes overshadowing extremely preterm survivors with more optimal outcomes. We aimed to describe an exceptionally early-born extremely preterm (EEEP) preschooler whose neurobiological, familial, and socioeconomic factors likely influenced her unexpected cognitive resilience. METHOD: Baby G was a 3-years 10-months-old, English-speaking, Caucasian, singleton girl born weighing 435 g at 22(5/7) weeks' gestation to well-educated married parents...

OBJECTIVE: To review the various ways in which baseline neuropsychological functioning is measured in the extant literature on pediatric brain tumors, describe the pros and cons of each approach, and increase the awareness of researchers as to the implications of each. METHOD: We reviewed the literature from 1993 to 2013, and classified studies by baseline approach and explicitness of selection of approach. RESULTS: There are multiple approaches to operationalizing baseline levels of ability and to assess change from baseline...

OBJECTIVE: The Clock Drawing Test (CDT) is widely used as a screening tool for discriminating cognitively normal individuals from patients with mild dementia. The aim of present study was to provide normative values for a 10-point quantitative scoring system proposed by Rouleau and colleagues (1992), including CDT total score and subscales score assessing representation of clock face (RC), layout of numbers (LN), and position of hands (PH), in a large sample of Italian healthy individuals...

OBJECTIVE: The purpose of the current study was to use a newly developed digital tablet-based variant of the TMT to isolate component cognitive processes underlying TMT performance. METHOD: Similar to the paper-based trail making test, this digital variant consists of two conditions, Part A and Part B. However, this digital version automatically collects additional data to create component subtest scores to isolate cognitive abilities. Specifically, in addition to the total time to completion and number of errors, the digital Trail Making Test (dTMT) records several unique components including the number of pauses, pause duration, lifts, lift duration, time inside each circle, and time between circles...

OBJECTIVE: Historically, the neuropsychological test traditions of the four Nordic countries have spanned from the flexible and qualitative tradition of Luria-Christensen to the quantitative large battery approach of Halstead and Kløve-Matthews. This study reports current test use and discusses whether these traditions still influence attitudes toward test use and choice of tests. METHOD: The study is based on survey data from 702 Nordic neuropsychologists. RESULTS: The average participant used 9 tests in a standard assessment, and 25 tests overall in their practice...

OBJECTIVE: Early detection of children with developmental delay is crucial for determining which children require close surveillance and intervention services. For many decades, the Bayley Scales has been the most widely used objective measure of early developmental delay, both in clinical and research settings. Significant structural changes were incorporated in the most recent edition, the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III). This article reviews the psychometric properties of the Bayley-III and investigates criticisms raised on the Bayley-III, namely that it overestimates developmental status and is a poor predictor of later functioning...

OBJECTIVE: Computerized neuropsychological assessment of concussion has rapidly expanded and Immediate Post-Concussion and Cognitive Testing (ImPACT) is among the most commonly used measures in this domain. ImPACT was primarily developed for use with athletic populations but continues to expand beyond athletics to settings such as the workplace and schools where motivational dispositions may vary. The purpose of the present study was to conduct a systematic review of existing research investigating the prevalence of invalid baseline results and the effectiveness of ImPACT's embedded invalidity indicators in detecting suspect effort...
