AIM: Cognitive impairments have been established as part of the non-motor phenomenology of adult dystonia. In childhood dystonia, the extent of cognitive impairments is less clear. This systematic review aims to present an overview of the existing literature to elucidate the cognitive profile of primary and secondary childhood dystonia. METHOD: Studies focusing on cognition in childhood dystonia were searched in MEDLINE and PsychInfo up to October 2017. We included studies on idiopathic and genetic forms of dystonia as well as dystonia secondary to cerebral palsy and inborn errors of metabolism...

Background: Attentional dysfunctions constitute core cognitive symptoms in schizophrenia, but the precise underlying neurocognitive mechanisms remain to be elucidated. Methods: In this randomized, double-blind, sham-controlled study, we applied, for the first time, a theoretically grounded modeling approach based on Bundesen's Theory of Visual Attention (TVA) to (i) identify specific visual attentional parameters affected in schizophrenia and (ii) assess, as a proof of concept, the potential of single-dose anodal transcranial direct current stimulation (tDCS; 20 min, 2 mA) to the left dorsolateral prefrontal cortex to modulate these attentional parameters...

Published studies assessing the association between cognitive performance and speech-in-noise (SiN) perception examine different aspects of each, test different listeners, and often report quite variable associations. By examining the published evidence base using a systematic approach, we aim to identify robust patterns across studies and highlight any remaining gaps in knowledge. We limit our assessment to adult unaided listeners with audiometric profiles ranging from normal hearing to moderate hearing loss...

OBJECTIVE: Older patients with bipolar disorder (BD) present with variable degrees of cognitive impairment. Over time, stress, mood episodes, and comorbidities increase the body's allostatic load. We assessed the extent to which allostatic load vs more traditional measures of medical burden account for the heterogeneity in cognition in this population. METHODS: Thirty-five older euthymic patients with BD and 30 age-equated, gender-equated, and education-equated comparison participants were administered a comprehensive assessment including a neuropsychological battery, and 9 physiological measures to determine allostatic load...

Background: Cognitive impairment is frequent and disabling in multiple sclerosis (MS). Changes in information processing speed constitute the most important cognitive deficit in MS. However, given the clinical and topographical variability of the disease, cognitive impairment may vary greatly and appear in other forms in addition to slower information processing speed. Our aim was to determine the frequency of cognitive impairment, the principal cognitive domains, and components involved in MS and to identify factors associated with presence of cognitive impairment in these patients in a large series of patients...

INTRODUCTION: Hyperprolactinaemia is commonly observed in people with psychotic disorders due to D2 receptor blockade by antipsychotic drugs, although it may also exist in drug-naïve patients with first-episode psychosis. Recent studies suggest that hyperprolactinaemia may have a negative impact on cognitive function in people with early psychosis. We aimed to explore whether there are sex differences in the association between prolactin levels and cognitive performance in early psychosis patients...

OBJECTIVE: Childhood trauma is common and associated with both worse cognitive performance and disruption to the hypothalamic-pituitary-adrenal axis in younger adults. The extent to which these associations persist into older adulthood remains unknown. The aim of this study was to investigate self-reported childhood trauma in relation to cognitive performance, and the extent to which cortisol explained this association, in 2 independent samples of older adults. METHODS: In this cross-sectional study, participants in the discovery sample (N = 76) consisted of older adults with a DSM-IV diagnosis of generalized anxiety disorder (N = 57) and age-equated psychiatrically healthy comparison subjects (N = 19) who were referred largely through primary care clinics between 2004-2006...

INTRODUCTION: There have been mixed findings assessing the impact of regular cocaine use on cognitive functioning. This study employed a comprehensive cognitive battery to compare the performance of individuals diagnosed with a cocaine use disorder (N = 3 abusers, N = 17 dependent) against the performance of two control groups: (a) non-drug-users, and (b) marijuana users who report no cocaine use (N = 7 marijuana abusers, N = 0 dependent, N = 13 marijuana users with no Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, DSM-IV, diagnosis)...

PURPOSE: Metaphor is a specific type of figurative language that is used in various important fields such as in the work with children in clinical or teaching contexts. The aim of the study was to investigate the developmental course, developmental steps, and possible cognitive predictors regarding metaphor processing in childhood and early adolescence. METHOD: One hundred sixty-four typically developing children (7-year-olds, 9-year-olds) and early adolescents (11-year-olds) were tested for metaphor identification, comprehension, comprehension quality, and preference by the Metaphoric Triads Task as well as for analogical reasoning, information processing speed, cognitive flexibility under time pressure, and cognitive flexibility without time pressure...

Objective: The obesity paradox has been documented in aged populations, yet it remains unclear if this paradox persists for physical and cognitive outcomes in community-dwelling older adult populations. Our study examines associations between body mass index (BMI) classification, cognitive function, and physical function. We also investigate whether these associations are modified by race or age. Design: Cross-sectional study. Setting: Senior residential sites and community centers in Saint Louis, Missouri...

OBJECTIVE: The cognitive model (Hirsch & Mathews, 2012) and attentional control theory (Eysenck & Derakshan, 2011) postulate that compromised executive function (EF) and other cognitive constructs are negatively linked to increased excessive and uncontrollable worry, the core symptom of generalized anxiety disorder (GAD). However, the prospective link between neuropsychological constructs and GAD are not well understood. METHODS: A nationally representative sample of 2605 community-dwelling adults whose average age was 55...

Veronika Lerche, Andreas Voss
The diffusion model (Ratcliff, Psychol Rev 85(2):59-108, 1978) is a stochastic model that is applied to response time (RT) data from binary decision tasks. The model is often used to disentangle different cognitive processes. The validity of the diffusion model parameters has, however, rarely been examined. Only few experimental paradigms have been analyzed with those being restricted to fast response time paradigms. This is attributable to a recommendation stated repeatedly in the diffusion model literature to restrict applications to fast RT paradigms (more specifically, to tasks with mean RTs below 1...

BACKGROUND: Walking ability recently emerged as a sub-clinical marker of cognitive decline. Hence, the relationship between baseline gait and future cognitive decline was examined in geriatric patients. Because a "loss of complexity" (LOC) is a key phenomenon of the aging process that exhibits in multiple systems, we propose the idea that age- and cognition-related LOC may also become manifested in gait function. The LOC theory suggests that even healthy aging is associated with a (neuro)physiological breakdown of system elements that causes a decline in variability and an overall LOC...

Mental effort is a common phenomenological construct deeply linked to volition and self-control. While it is often assumed that the amount of exertion invested in a task can be voluntarily regulated, the neural bases of such faculty and its behavioural effects are yet insufficiently understood. In this study, we investigated how the instructions to execute a demanding cognitive task either "with maximum exertion" or "as relaxed as possible" affected performance and brain activity. The maximum exertion condition, compared to relaxed execution, was associated with speeded motor responses without an accuracy trade-off, and an amplification of both task-related activations in dorsal frontoparietal and cerebellar regions, and task-related deactivations in default mode network (DMN) areas...

The main purpose of this pilot study was to examine the feasibility and the effects of a multimodal exercise intervention on the physical and cognitive functioning of institutionalized older people. Twenty-one older adults (83.5 ± 4.9 years) living in two nursing home residences, were tested on two occasions 4 weeks apart to establish a baseline measure, and then engage in the exercise program twice weekly for 8 weeks. Participants were tested again after the exercise program. Almost all physical fitness and cognitive tests were unchanged at baseline measures, but after the exercise program, significant improvements (p < 0...

Rodent studies demonstrate that supplementing the maternal diet with choline during pregnancy produces life-long cognitive benefits for the offspring. In contrast, the two experimental studies examining cognitive effects of maternal choline supplementation in humans produced inconsistent results, perhaps because of poor participant adherence and/or uncontrolled variation in intake of choline or other nutrients. We examined the effects of maternal choline supplementation during pregnancy on infant cognition, with intake of choline and other nutrients tightly controlled...

Radiation therapy (RT) is integral in the treatment of pediatric brain tumors; however, photon RT (XRT) often results in intellectual decline, executive functioning (EF) deficits, academic underachievement/failure, and lower health-related quality of life (HRQoL). Proton RT (PRT) provides more targeted therapy, minimizing damage to the developing brain, yet few studies have examined its neuropsychological effects. This study investigated the role of EF in academic skills and HRQoL in a sample of children treated with PRT...

BACKGROUND: Previous research has suggested that there is a degree of variability among older adults' response to memory training, such that some individuals benefit more than others. The aim of the present study was to identify the profile of older adults who were likely to benefit most from a strategic memory training program that has previously proved to be effective in improving memory in healthy older adults. METHOD: In total, 44 older adults (60-83 years) participated in a strategic memory training...

Mucopolysaccharidosis Type II (MPS II) or Hunter Syndrome is a rare X-linked condition, due to a defect in a lysosomal enzyme involved in the breakdown of glycosaminoglycans. It is a progressive condition with worsening over time; however, symptom severity and progression rates vary. Normal intellectual function has been reported in males with mild MPS II but few studies are available that provide comprehensive cognitive profiles. Enzyme replacement therapy (ERT) can stabilize physical symptoms and has become standard treatment...
