OBJECTIVE: Parkinson's disease (PD) has long been conceptualized as a motor disorder, but nonmotor symptoms also manifest in the disease and significantly reduce quality of life. Anxiety and cognitive dysfunction are prevalent nonmotor symptoms, even in early disease stages, but the relation between these symptoms remains poorly understood. We examined self-reported anxiety and neurocognitive function, indexed by measures of executive function (set-shifting and phonemic fluency), categorical fluency, and attention/working memory...

OBJECTIVE: Cognitive deficits are common in Parkinson's disease (PD) and exacerbate the functional limitations imposed by PD's hallmark motor symptoms, including impairments in walking. Though much research has addressed the effect of dual cognitive-locomotor tasks on walking, less is known about their effect on cognition. The purpose of this study was to investigate the relation between gait and executive function, with the hypothesis that dual tasking would exacerbate cognitive vulnerabilities in PD as well as being associated with gait disturbances...

OBJECTIVE: Previous studies have shown that Music-Supported Therapy (MST) can improve the motor function and promote functional neuroplastic changes in motor areas; however, the time course of motor gains across MST sessions and treatment periods remain unknown. The aim of this study was to explore the progression of the rehabilitation of motor deficits in a chronic stroke patient for a period of 7 months. METHOD: A reversal design (ABAB) was implemented in a chronic stroke patient where no treatment was provided in the A periods and MST was applied in the B periods...

OBJECTIVE: The authors investigated whether children with Down's syndrome (DS) who have not started to produce number words understand the one-to-one correspondence principle (Experiment 1), and they looked at the relationship between number word knowledge and receptive vocabulary (Experiment 2). METHOD: Sixteen children with DS who did not recite the count list participated in Experiment 1, along with 2 comparison groups: 1 of 16 children with DS who recited up to 10, paired by chronological age, and another of 16 typically developing children paired by their ability to recite the list...

OBJECTIVE: Research on early cognitive markers of Alzheimer's disease is primarily focused on retrospective recall (of word lists, pairs of items, stories) and executive functions. However, research shows that people with amnestic mild cognitive impairment (aMCI), who are at a higher risk of developing the disease than healthy controls, are particularly impaired in remembering to do things in the future or prospective memory (PM). The aim of this study was to establish which type of event-based PM is particularly disrupted in aMCI, focal PM, based on spontaneous retrieval, or nonfocal PM that relies on strategic monitoring processes...

BACKGROUND: Theory of mind (ToM) is the ability to understand and interpret another person's beliefs, intentions (cognitive ToM) and emotions (affective ToM). OBJECTIVE: To explore affective and cognitive ToM and their neuropsychological correlates in patients affected by multiple sclerosis (MS). MATERIAL AND METHOD: Forty MS patients and 40 matched control individuals underwent tasks assessing cognitive (the ToM Pictures Sequencing Task and the Advanced Test of ToM) and affective ToM (the Reading the Mind in the Eyes Task and the Emotion Attribution Task), in both verbal and nonverbal modality, a comprehensive neuropsychological battery, and questionnaires for behavioral disorders...

OBJECTIVE: Evidence from several cross-sectional studies indicates that an increase in omega-6 to omega-3 fatty acids (FAs) may negatively affect cognition in old age. The hippocampus is among the first neural structures affected by age and atrophy in this brain region is associated with cognitive decline. Therefore, we hypothesized that a lower omega-6:3 FA ratio would predict better hippocampus-dependent spatial memory, and a higher general cognitive status. METHOD: Fifty-two healthy older adults completed a Food Frequency Questionnaire, the Montreal Cognitive Assessment test (MoCA; a test of global cognition) and virtual navigation tasks that assess navigational strategies and spatial memory...

OBJECTIVE: The object of the present study is to advance our understanding of the cognitive profile of Rett syndrome (RTT), an X-linked neurodevelopmental disorder caused by mutations in the MECP2 gene. We focus on sustained attention, which plays a critical role in driving cognitive growth, and use an innovative, gaze-based task that minimizes demands on the limited verbal and motor abilities associated with RTT. METHOD: The task required the ability to sustain attention on a visual target (a butterfly) while inhibiting a prepotent response to look to moving distractors (trees and clouds) presented in the peripheral visual field...

OBJECTIVE: To characterize the language impairments that occur in brain tumor patients using a cognitively oriented theoretical framework. METHOD: Forty-nine preoperative brain tumor patients completed a new testing protocol (the BLAST) which assesses 8 well documented, "core" cognitive skills required for language: auditory word recognition, accessing semantic knowledge, lexical selection, phonological encoding, verbal short-term memory, goal-driven language selection, verb retrieval, and articulatory-motor planning...

OBJECTIVE: Previous research suggests visual short-term memory (VSTM) capacity and mathematical abilities are significantly related. Moreover, both processes activate similar brain regions within the parietal cortex, in particular, the intraparietal sulcus; however, it is still unclear whether the neuronal underpinnings of VSTM directly correlate with mathematical operation and reasoning abilities. The main objective was to investigate the association between parieto-occipital brain activity during the retention period of a VSTM task and performance in mathematics...

OBJECTIVE: This study tested the role of temporary memory, measured by phonological short-term memory (pSTM) and verbal working memory (vWM), as a mediator of the effect of 3 putative risk factors (i.e., socioeconomic status, home literacy environment, birth gestational age) upon expressive and receptive language. METHOD: A community-based sample of 646 Italian children aged 6-11 years was assessed with a comprehensive battery of language and cognitive tests. A mediation analysis was used to examine whether memory mediates environmental/biological effects on language...

OBJECTIVE: The alien hand syndrome (AHS) is a rare neuropsychological disorder characterized by involuntary, yet purposeful, hand movements. Patients with the AHS typically complain about a loss of agency associated with a feeling of estrangement for actions performed by the affected limb. The present study explores the integrity of the body representation in AHS, focusing on 2 main processes: multisensory integration and visual self-recognition of body parts. Three patients affected by AHS following a right-hemisphere stroke, with clinical symptoms akin to the posterior variant of AHS, were tested and their performance was compared with that of 18 age-matched healthy controls...

OBJECTIVE: Attention-deficit hyperactivity disorder (ADHD) is a complex developmental neuropsychiatric disorder, characterized by inattentiveness, impulsivity, and hyperactivity. Recent literature suggests a potential core deficit underlying these behaviors may involve inefficient processing when contextual stimulation is low. In order to specify this inefficiency, the aim of the present study was to disentangle perceptual and response-based deficits of attention by supplementing classic reaction time (RT) measures with an accuracy-only test...

OBJECTIVE: The lack of inversion effect for face recognition in congenital prosopagnosia (CP) is consistent with the hypothesis of a failure in holistic processing. However, although CPs' abnormal gaze behavior for upright faces has already been demonstrated, neither their scanning strategy for inverted faces, nor the possibility that their abnormal gaze behavior with upright faces is because of reasons other than the holistic deficit have been investigated yet. METHOD: We recorded the eye movements of a congenital prosopagnosic and a control group during the encoding of unknown faces, objects, and flowers...

OBJECTIVE: To identify cognitive subgroups (comprising neurocognition and social cognition domains) within first-episode psychosis (FEP) patients including a healthy control group for comparison. Predictive validity of cognitive clusters in relation to symptoms and functioning was also investigated. METHOD: A comprehensive cognitive battery was administered to 133 FEP participants and 46 healthy controls. Ward's method hierarchical agglomerative cluster analysis with k-means verification was used to determine clusters...

OBJECTIVE: To characterize the hemispheric processing of metaphors in adults with ADHD compared to controls. METHOD: We investigated the hemispheric processing of metaphors in 24 adult participants diagnosed with ADHD and 24 control participants. The hemispheric processing was examined using a divided visual field paradigm, in which different kinds of metaphors as well as literal word pairs and unrelated word pairs were presented either to the right visual field/left hemisphere (RVF/LH) or to the left visual field/right hemisphere (LVF/RH)...

OBJECTIVES: Recent findings suggest that mental arithmetic involves shifting attention on a mental continuum in which numbers would be ordered from left to right, from small to large numbers, with addition and subtraction causing rightward or leftward shifts, respectively. Neuropsychological data showing that brain-damaged patients with left neglect experience difficulties in solving subtraction but not addition problems support this hypothesis. However, the reverse dissociation is needed to establish the causal role of spatial attention in mental arithmetic...

OBJECTIVE: Decision-making involves fronto-striatal brain areas that are particularly vulnerable to the effects of HIV infection. Some studies report impaired decision-making in people with HIV/AIDS with past or present addictions and/or accompanying HIV-associated neurocognitive disorders (HAND). The authors investigated risk-based decision-making in HIV/AIDS, separating individuals with or without accompanying HAND. METHOD: A total of 288 HIV-infected persons underwent standardized neuropsychological testing...

OBJECTIVE: Cognitive impairment is prevalent and related to functional outcome in schizophrenia, but a significant minority of the patient population overlaps with healthy controls on many performance measures, including declarative-verbal-memory tasks. In this study, we assessed the validity, clinical, and functional implications of normal-range (NR), verbal-declarative memory in schizophrenia. METHOD: Performance normality was defined using normative data for 8 basic California Verbal Learning Test (CVLT-II; Delis, Kramer, Kaplan, & Ober, 2000) recall and recognition trials...

OBJECTIVE: Despite early dietary treatment phenylketonuria patients have lower IQ and poorer executive functions compared to healthy controls. Cognitive problems in phenylketonuria have often been associated with phenylalanine levels. The present study examined the cognitive profile and mental health in adult phenylketonuria, in relation to phenylalanine levels and tetrahydrobiopterin treatment. METHOD: Fifty-seven early treated adult patients with phenylketonuria and 57 healthy matched controls (18-40 years) performed IQ subtests and executive function tests from the Amsterdam Neuropsychological Tasks...
