INTRODUCTION: The enzyme steroid sulfatase (STS) converts sulfated steroids to their non-sulfated forms. Deficiency for this enzyme is associated with inattention but preserved response control. The polymorphism rs17268988 within the X-linked STS gene is associated with inattentive, but not other, symptoms in boys with attention deficit hyperactivity disorder (ADHD). METHODS: We initially tested whether rs17268988 genotype was associated with attention, response control, and underlying aspects of cognition, using questionnaires and neuropsychological tasks, in two independent cohorts of healthy adult males...

INTRODUCTION: Current recommendations for concussion management acknowledge the importance of objective assessments of neuropsychological (NP) ability, and computerized NP assessments have been widely integrated into the concussion management protocols of high schools. The optimal intervals for baseline test administration in high-school athletes are currently uncertain. The ability to accurately detect subtle NP deficits is particularly important for high-school athletes, in which concussions are increasingly recognized for adverse effects to the developing brain...

RATIONALE: Early life stress combined with heavy adolescent alcohol use predicts impaired neuropsychological functioning in adulthood. We investigated whether adolescent intermittent ethanol (AIE) exposure combined with neonatal maternal separation in rats altered attentional processes and impulsivity in adulthood. METHODS: Male Wistar rat pups were exposed to maternal separation (postnatal days (PNDs) 1-14) and moderate AIE exposure (PNDs 28-57). Adult rats were tested in the five-choice serial reaction time task, which provides separate measures of attention, motor impulsivity, and compulsivity...

Objective: Existing cognitive and clinical predictors of treatment response to date are not of sufficient strength to meaningfully impact treatment decision making and are not readily employed in clinical settings. This study investigated whether clinical and cognitive markers used in a tertiary care clinic could predict response to usual treatment over a period of 4 to 6 months in a sample of 75 depressed adults. Methods: Patients (N = 384) were sequentially tested in 2 half-day clinics as part of a quality improvement project at an outpatient tertiary care center between August 2003 and September 2007; additional subjects evaluated in the clinic between 2007 and 2009 were also included...

OBJECTIVE: The cognitive neuropsychological model of depression proposes that negative biases in the processing of emotionally salient information have a central role in the development and maintenance of depression. We have conducted a systematic review to determine whether acute experimental inflammation is associated with changes to cognitive and emotional processing that are thought to cause and maintain depression. METHODS: We identified experimental studies in which healthy individuals were administered an acute inflammatory challenge (bacterial endotoxin/vaccination) and standardised tests of cognitive function were performed...

BACKGROUND & AIMS: Covert hepatic encephalopathy (CHE) is frequently seen in cirrhotic patients. CHE can be diagnosed by a computerized neuropsychological test system (NPT); however, NPT has not been updated about two decades in Japan. The aim of this study is to update the NPT for fitting the elderly and modern society by resetting of the cut-off values. METHODS: We enrolled 367 healthy subjects with 40 to 79 years old between 2003 and 2010. NPT consist of following 8 tests: number connection tests A and B, a figure position test, a digit symbol test, a block design test, and reaction time test A, B, and C...

Executive tasks are important instruments for neuropsychological and cognitive research, but only a limited number of studies have investigated the test-retest reliability of these tasks. Such information is needed for optimizing task usage, for example, in longitudinal and intervention studies. In this study with healthy adults, we investigated the temporal stability of five executive tasks: the Simon task, a visuoverbal N-back task, a visuospatial N-back task, a running memory task, and the Number-letter task...

OBJECTIVE: The extent to which increasing age is associated with impairment in cognitive function, termed cognitive aging, may have been overestimated in prior studies. The inclusion of individuals with severe or uncontrolled systemic medical illness or prodromal neurodegenerative disease in normal aging samples is likely to bias estimates toward lower cognitive performance and inflate estimates of variability. METHOD: Unbiased estimates of cognitive aging in 658 adults aged 60-84, who underwent rigorous screening to ensure their general and cognitive health, were computed...

OBJECTIVES: Cognitive dysfunction from high altitude exposure is a major cause of civilian and military air disasters. Pilot training improves recognition of the early symptoms of altitude exposure so that countermeasures may be taken before loss of consciousness. Little is known regarding the nature of cognitive impairments manifesting within this critical window when life-saving measures may still be taken. Prior studies evaluating cognition during high altitude simulation have predominantly focused on measures of reaction time and other basic attention or motor processes...

The effect of normal aging on lexical production and semantic processing was evaluated in 72 healthy participants. Four tasks were used, picture naming (PN), picture categorization (PC), numerical judgment (NJ), and color judgment (CJ). The dependence of reaction time (RT) and correct responses with age was accounted by mixed-effects models. Participants underwent neuropsychological testing for verbal, executive, and memory functions. The RTs increase significantly with age for all tasks. After parceling out the non-specific cognitive decline, as reflected by the NJ task, the RT for the PN task decreases with age...
