INTRODUCTION: Phenylketonuria (PKU) is a rare metabolic disease that causes slight-to-severe neurological symptoms. Slow performance has been observed in PKU but the influence of high-order (i.e., not purely motor) deficits and of temporary variations of the phenylalanine (Phe) level on this slowness has not been fully corroborated as yet. Response speed and the effect of motor practice during the performance of a visuomotor coordination task were measured, in a group of patients with early-treated phenylketonuria (ET PKU)...

OBJECTIVE: Prospective memory (PM) is crucial to the maintenance of functional independence in late adulthood and is consistently impaired in mild cognitive impairment (MCI). There remains a need for brief but valid measures of this construct that can be used as part of a comprehensive clinical assessment of cognition. Since the distinctiveness of PM cues is argued to determine the degree of strategic, controlled demands of PM paradigms, two variants of a brief measure were developed, one of which presented low-salience and the other high-salience PM cues...

As the HIV+ population ages, the risk for and need to screen for HIV-associated neurocognitive disorders (HAND) increases. The aim of this study is to determine the utility and ecological validity of the Montreal Cognitive Assessment (MoCA) among older HIV+ adults. A total of 100 HIV+ older adults aged 50 years or over completed a comprehensive neuromedical and neurocognitive battery, including the MoCA and several everyday functioning measures. The receiver operating characteristic curve indicates ≤26 as the optimal cut-off balancing sensitivity (84...

INTRODUCTION: Olfactory dysfunction (OD) has been suggested as a possible marker of executive function (EF) deficits after traumatic brain injury (TBI) in adults. Little is known about the relationship between EF and OD in pediatric TBI (pTBI). This study aimed to investigate EF, explore the relationship between OD and EF, and determine the utility of olfactory performance as a marker of later EF in pTBI. It was hypothesized that (i) children with TBI would perform more poorly on EF measures relative to normative expectation; (ii) children with OD would perform more poorly on tests of EF than those with normal olfaction after TBI; and (iii) acute olfactory function would predict later EF for children with TBI...

INTRODUCTION: Diagnosis threat has been shown to produce detrimental effects on neuropsychological performance in individuals with mild traumatic brain injury (mTBI). Focusing on contact-sport players who are at great risk of mTBI, our study was designed to examine the moderating role of internal locus of control. Specifically, we predicted that following diagnosis threat (reminder of their risk of sustaining mTBI and of its consequences), low-internal contact-sport players would underperform (assimilation to the stereotype), while their high-internal counterparts would outperform (contrast effect)...

The serial position effect reveals that recall of a supraspan list of words follows a predictable pattern, whereby words at the beginning (primacy) and end (recency) of a list are recalled more easily than words in the middle. This effect has typically been studied using single list-learning trials, but in neuropsychology, multi-trial list-learning tests are more commonly used. The current study examined trends in learning for primacy, middle, and recency effects across multiple trials in younger and older age cohorts...

The present study was composed of two parts examining the clinical utility of the Delis-Kaplan Executive Function System (D-KEFS) Verbal Fluency and Color-Word subtests in traumatic brain injury (TBI). In the first part, the performance of 128 outpatients with mild to severe TBI on the Verbal Fluency and Color-Word subtests was examined in relation to two primary indicators of TBI severity: length of coma and the presence of intracranial lesions on neuroimaging through regression analysis. After controlling for education, ethnicity, and complicating premorbid and comorbid factors, length of coma predicted performance on the Color-Word Inhibition/Switching subtest, whereas the presence of diffuse lesions was related to Verbal Fluency Category Switching performance...

INTRODUCTION: Executive function deficits are prevalent in people with multiple sclerosis (PwMS), and PwMS use less adaptive coping than healthy controls. This cross-sectional study assessed whether there is a relationship between executive function and coping in PwMS. METHOD: One hundred and seven participants with relapsing remitting or secondary progressive MS (n = 83 and 24, respectively; age M = 48.8 ± 11.1 years) completed measures of coping and executive function...

INTRODUCTION: Cross-modal interactions improve the processing of external stimuli, particularly when an isolated sensory modality is impaired. When information from different modalities is integrated, object recognition is facilitated probably as a result of bottom-up and top-down processes. The aim of this study was to investigate the potential effects of cross-modal stimulation in a case of simultanagnosia. METHOD: We report a detailed analysis of clinical symptoms and an (18)F-fluorodeoxyglucose (FDG) brain positron emission tomography/computed tomography (PET/CT) study of a patient affected by Balint's syndrome, a rare and invasive visual-spatial disorder following bilateral parieto-occipital lesions...

INTRODUCTION: The current study sought to determine the optimal impairment rating definition for a new HIV-associated neurocognitive disorder (HAND) screening procedure as compared to standard neuropsychological testing. METHOD: A total of 55 HIV-infected (HIV+; 19% AIDS; 87% on combination antiretroviral therapy, cART; 80% plasma undetectable) and 22 demographically comparable HIV-uninfected (HIV-) control adults (all male) enrolled in an urban Australian primary care cohort study completed the CogState computerized cognitive screen, a standard independence in activities of daily living (ADL) questionnaire, and a standard neuropsychological test battery...

INTRODUCTION: Intraindividual variability (IIV) in motor performance has been shown to predict future cognitive decline. The apolipoprotein E-epsilon 4 (APOE-ε4) allele is also a well-established risk factor for memory decline. Here, we present novel findings examining the influence of the APOE-ε4 allele on the performance of asymptomatic healthy elders in comparison to individuals with amnestic MCI (aMCI) on a fine motor synchronization, paced finger-tapping task (PFTT). METHOD: Two Alzheimer's disease (AD) risk groups, individuals with aMCI (n = 24) and cognitively intact APOE-ε4 carriers (n = 41), and a control group consisting of cognitively intact APOE-ε4 noncarriers (n = 65) completed the Rey Auditory Verbal Learning Test and the PFTT, which requires index finger tapping in synchrony with a visual stimulus (interstimulus interval = 333 ms)...

INTRODUCTION: Comparative efficacy and safety are important issues for appropriate drug selection for attention-deficit hyperactivity disorder (ADHD) treatment. Therefore we conducted a meta-analysis, where we compared atomoxetine (ATX) and methylphenidate (MPH) for ADHD treatment in children and adolescents. METHOD: Literature retrieval was conducted in relevant databases from their inception to April 2016 to select head-to-head trials that compared ATX and MPH in children and adolescents...

BACKGROUND: Vocabulary scores tend to be significantly related to education in heterogeneous groups of older adults, even after controlling for confounding variables. However, there may be other factors that impinge on cognitive functioning for certain demographic groups, particularly those whose educational opportunities were limited, and who may have experienced considerable stress as a result of their minority status. OBJECTIVES: This study sought to explore possible predictors of vocabulary scores among African American and White older adults...

BACKGROUND: Action monitoring, the process for evaluating the appropriateness of one's own actions, is reported to be atypical in individuals with autism spectrum disorder (ASD). METHOD: We examined the characteristics of action monitoring in 11 children with ASD and 12 children with typical development (TD), analyzing stimulus-locked and response-locked event-related potential components (i.e., N2; error-related negativity, ERN; and error positivity, Pe) related to execution of a flanker task...

INTRODUCTION: Studies investigating the neurocognitive effects of posttraumatic stress disorder (PTSD) routinely find "deficits" in various cognitive domains. However, the rate of cognitive impairment in individuals with PTSD remains unclear, as studies have focused on null hypothesis testing (NHT) and inferring patterns of impairment rather than empirically determining the rate of cognitive impairment in this sample. METHOD: This study examined rates of cognitive impairment using a domain-specific approach in non-treatment-seeking Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn service members and veterans with (n = 92) and without (n = 79) PTSD and without substance abuse/dependence who passed a performance validity measure and were matched on age, education, estimated IQ, and ethnicity...

: Unilateral spatial neglect (USN) is a syndrome that can occur after right- and left-hemisphere damage. It is generally accepted that left-sided USN is more severe than right-sided USN. Evidence for such a difference in other domains is lacking. Primary aims were to compare frequency, severity, region specificity, cognition, physical functioning, and physical independence between left and right USN. Secondary aims were to compare lesion characteristics. A total of 335 stroke patients admitted for inpatient rehabilitation were included...

INTRODUCTION: Prematurely born preschoolers show developmental cognitive delay compared to full-term children. There are important neurological networks developing at preschool age related to perspective taking about the attribution of belief and to deduction with contrary-to-fact situations. Other deductive abilities may be completed during that period. METHOD: A group of very prematurely born children (N = 35) aged between 4 and 5 years was compared with a control group of children born at full term (N = 35)...

INTRODUCTION: Few studies have directly investigated impulsivity in Huntington's disease (HD) despite known changes in dopaminergic and frontal functioning, changes that have been associated with impulsivity in other disorders and in the normal population. This study sought to further categorize impulsivity in HD through examining differences in self-reported impulsivity between community controls and HD patients, the relationship between executive dysfunction and impulsivity, and the relationship of a reward/punishment behavioral inhibition task in relation to these self-report measures...

INTRODUCTION: The clinical assessment of affective functioning has been slow to incorporate findings from affective neuroscience. Of particular interest in the current study is the assessment of affective word production. METHOD: In a series of four studies, we examined test-retest and interrater reliability for the Emotion Word Fluency Test (EWFT), basic construct validity with existing verbal fluency measures, physiological responses across verbal fluency tasks, and a novel scoring method to examine qualitative aspects of participant response sets...

INTRODUCTION: Cognitive reserve (CR) was proposed to explain how individual differences in brain function help to cope with the effects of normal aging and neurodegenerative diseases. Education, professional solicitations, and engagement in leisure and physical activities across the lifetime are considered as major determinants of this reserve. METHOD: Using multiple linear regression analyses, we tested separately in healthy elderly and Parkinson's disease (PD) populations to what extent cognitive performance in several domains was explained by (a) any of these four environmental lifespan variables; (b) demographic and clinical variables (age, gender, depression score, and, for the PD group, duration of disease and dopaminergic drugs)...
