Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by chronic, profound, disabling, and unexplained fatigue; cognitive impairment; and chronic widespread pain. By using positron emission tomography, our study demonstrated neuroinflammation in the brain of patients with ME/CFS. Neuroinflammation was found to be widespread in the brain areas of the patients with ME/CFS and was associated with the severity of their neuropsychological symptoms. The ongoing research would lead to the establishment of objective diagnostic criteria and development of an appropriate therapy...

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disease characterized by chronic, profound, disabling, and unexplained fatigue. The first patient with ME/CFS in Japan was identified and described in 1990 by Prof. Teruo Kitani and Dr. Hirohiko Kuratsune of the Research Institute for Microbial Diseases, Osaka University. Since then, a variety of studies have been performed to determine the objective biomarkers of the disease. Although it is hypothesized that brain inflammation is involved in the pathophysiology of ME/CFS, there is to date no direct evidence of neuroinflammation in patients with ME/CFS...

Effects of Bilingualism on Cognitive Functions in Early Childhood Studies have revealed advantages in cognitive functions among children with bilingualism. In this study we investigate cognitive functions in monolingual and bilingual preschool children taking socioeconomic status into account. The study population consists of 40 monolingual (German) children (Mage = 5.0 ± 0.4) and 23 bilingual (German/English) children (Mage = 5.1 ± 0.6). A neuropsychological test battery was conducted. The analyses revealed better performance for bilingual children...

Despite the accumulated knowledge on moral decision-making in the early stages of development, empirical evidence is still limited in the old-aged adults. The current study contributes to unveil the neural correlates of judgments of moral transgressions as a function of aging, by examining the temporal dynamics of neural activation elicited by intentional and accidental harmful actions in three groups of healthy participants: young adults (18-35), adults (40-55), and older adults (60-75). Older adults were slower and less accurate in rating intentionality, compared to the younger groups...

OBJECTIVE: Neuropsychological tests undergo periodic revision intended to improve psychometric properties, normative data, relevance of stimuli, and ease of administration. In addition, new tests are developed to evaluate psychological and neuropsychological constructs, often purporting to improve evaluation effectiveness. However, there is limited professional guidance to neuropsychologists concerning the decision to adopt a revised version of a test and/or replace an older test with a new test purporting to measure the same or overlapping constructs...

BACKGROUND/OBJECTIVES: Behavioral problems in individuals with Alzheimer's disease (AD) impose major management challenges. Current prevention strategies are anchored to cognitive outcomes, but behavioral outcomes may provide another, clinically relevant opportunity for preemptive therapy. We sought to determine whether personality changes that predispose to behavioral disorders arise during the transition from preclinical AD to mild cognitive impairment (MCI). DESIGN: Longitudinal observational cohort study...

OBJECTIVES: Generalized tonic-clonic status epilepticus (GTC-SE) is considered a risk for cognitive impairment. Research with standardized tools is scarce and non-conclusive. We systematically assessed short-term and long-term cognitive function after GTC-SE. MATERIALS AND METHODS: Thirty-three patients were tested after the clinical post-ictal phase of GTC-SE (timepoint 1) and again after 1 year (timepoint 2). Twenty controls were examined with the same tests...

BACKGROUND: The term "Subjective Cognitive Impairment (SCI)" is the most widely accepted term for cognitive complaints of otherwise apparently healthy older adults. It is presently clear that SCI might be a risk factor for the development of Mild Cognitive Impairment and dementia. As regards SCI measurement and potential diagnosis, several studies showed that SCI is a condition in which people score in the normal range on common tests but believe they experience cognitive decline. Hence, to assess the characteristic of the SCI subtle cognitive decline, self-report measures were developed to estimate "self-experience" of minimal decline in cognition seem the most appropriate tools...

BACKGROUND: Adults over age 65 represent the fastest growing population in the US. Decline in cognitive abilities is a hallmark of advanced age and is associated with loss of independence and dementia risk. There is a pressing need to develop effective interventions for slowing or reversing the cognitive aging process. While certain forms of cognitive training have shown promise in this area, effects only sometimes transfer to neuropsychological tests within or outside the trained domain...

Objective: The provision of neuropsychological assessments is an important part of the assessment and treatment of our veterans, yet little is known regarding who provides these assessments within Veterans Health Administration (VHA) settings, and of what they consist. The current survey provides information regarding the professional characteristics and assessment practices of VHA psychologists who provide neuropsychological assessments within VHA settings. Methods: Survey invitations were emailed to 4740 psychologists who worked for the VHA, resulting in surveys from 123 VHA psychologists who self-identified as providing and/or supervising neuropsychological assessments within VHA settings...

OBJECTIVE: Identifying which preterm (PT) children are at increased risk of language and learning differences increases opportunities for participation in interventions that improve outcomes. Speed in spoken language comprehension at early stages of language development requires information processing skills that may form the foundation for later language and school-relevant skills. In children born full-term, speed of comprehending words in an eye-tracking task at 2 years old predicted language and nonverbal cognition at 8 years old...

Ciguatoxins (CTXs) are lipid-soluble polyether compounds produced by dinoflagellates from the genus Gambierdiscus spp. typically found in tropical and subtropical zones. This endemic area is however rapidly expanding due to environmental perturbations, and both toxic Gambierdiscus spp. and ciguatoxic fishes have been recently identified in the North Atlantic Ocean (Madeira and Canary islands) and Mediterranean Sea. Ciguatoxins bind to Voltage Gated Sodium Channels on the membranes of sensory neurons, causing Ciguatera Fish Poisoning (CFP) in humans, a disease characterized by a complex array of gastrointestinal, neurological, neuropsychological, and cardiovascular symptoms...

BACKGROUND: Neurocognitive impairment (NCI) is one of the most common complications of HIV infection, and has serious medical and functional consequences. South Africa has 7 million people living with HIV (PLHIV) with up to three-quarters of antiretroviral therapy (ART)-naïve individuals having NCI. South Africa's health system struggles to meet the care needs of its millions of PLHIV; screening for NCI is typically neglected due to limited clinical staff trained to administer, score, and interpret neuropsychological tests, as well as long test batteries and limited screening tools for South African populations...

Drug addiction or substance-use disorder is a chronically relapsing disorder that progresses through binge/intoxication, withdrawal/negative affect and preoccupation/anticipation stages. These stages represent diverse neurobiological mechanisms that are differentially involved in the transition from recreational to compulsive drug use and from positive to negative reinforcement. The progression from recreational to compulsive substance use is associated with downregulation of the brain reward systems and upregulation of the brain stress systems...

Introduction: Almost 2 million U.S. youth are estimated to live on the streets, in shelters, or in other types of temporary housing at some point each year. Both their age and living situations make them more likely to engage in high-risk behaviors, particularly during adolescence, a time of increased risk taking. Much of self-control appears related to the development of the prefrontal cortex, which is at a particularly crucial period of elaboration and refinement during adolescence and emerging adulthood...

BACKGROUND: Cancer survival comes at a price: pediatric cancer survivors bear a high risk for a wide range of cognitive difficulties. Therefore, interventions targeting these difficulties are required. The aim of the present clinical trial is to extend empirical evidence about efficacy of cognitive and physical training in pediatric cancer survivors. It is hypothesized that early cognitive and physical interventions affect the remediation of pediatric cancer survivors in terms of improved executive functions (primary outcome)...
