Background: Slowed processing speed is the most frequently reported cognitive deficit for people with multiple sclerosis (MS). However, measures used to assess processing speed may also recruit other cognitive abilities. The present objective was to determine the contributions of different cognitive functions to performance on two commonly used processing speed measures: the Symbol Digit Modalities Test (SDMT) and the Paced Auditory Serial Addition Test (PASAT).

(b) How much can an organization influence members' sharing indirectly through targeting attitudes, and/or directly through targeting behaviors? We draw on ambivalence, nudging, and privacy paradox theories to examine these important questions using samples of university students in the context of setting up public student profile pages viewable to other members of their institution. We find that positive, negative, and ambivalent attitudes coexist in the population (Study 1). We also find that individuals are cognizant of privacy-intrusiveness (Study 2), suggesting sharing is not mindless.

Much of this work has focused on a receiver's emotional response to anger. Yet little work has examined the influence of anger on information search, an important cognitive mechanism for joint value creation in integrative negotiations.

Objective: We aimed to establish the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) as a feasible cognitive monitoring tool and provide Canadian data toward the international validation effort. Secondary considerations were to determine if BICAMS correlates with self-reported cognition and predicted vocational status.
Curiosity about collective affect is undergoing a revival in many fields. This literature, tracing back to Le Bon's seminal work on crowd psychology, has established the veracity of collective affect and demonstrated its influence on a wide range of group dynamics. More recently, an interest in the perception of collective affect has emerged, revealing a need for a methodological approach for assessing collective emotion recognition to complement measures of individual emotion recognition.

However, the lack of adequate normative data has limited its clinical utility. Recently published regression-based norms may resolve this limitation but, because these norms were derived from a relatively small sample, their stability is unclear.

Setting: The study was conducted in a community setting.
Participants: We enrolled adults with symptoms of depression after a traumatic brain injury.
The Relative Consequence Model proposes multiple sclerosis (MS) patients have a fundamental deficit in processing speed that compromises other cognitive functions. The present study examined the mediating role of processing speed,as well as working memory, in the MS-related effects on other cognitive functions for early relapsing-remitting patients. Seventy relapsing-remitting MS patients with disease duration not greater than 10 years and 72 controls completed tasks assessing processing speed, working memory, learning, and executive functioning.

The Paced Auditory Serial Addition Test (PASAT), Symbol Digit Modalities Test (SDMT), and Computerized Test of Information Processing (CTIP) are used to measure IPS. Both the PASAT and SDMT are sensitive to deficits in IPS.

However, the efficacy and safety of DA in this population is not well established. We conducted a systematic review of randomized controlled trials (RCTs) examining the clinical efficacy and safety of DA in patients with TBI.

Apolipoprotein E (APOE) is involved in central acetylcholine synthesis, and patients bearing the ε4 genotype (APOE-ε4) are at increased risk of both vascular dementia and peripheral vascular disease. The purpose of this study was to evaluate the associations among delirium, POCD, and APOE-ε4 in patients undergoing open aortic repair.

The CDT takes a maximum of two minutes to complete and might be helpful in identifying postoperative cognitive disorders at the bedside. The objective of this study was to evaluate the accuracy of the CDT in a population at high risk for postoperative cognitive disorders
Methods: In this prospective observational cohort study, patients were recruited who were ≥ 60 yr of age and scheduled for elective open repair of the abdominal aorta.
Objective: Cognitive rehabilitation represents a substantial portion of rehabilitative efforts put forth in increasing independence following an acquired brain injury.
Main Outcomes And Results: This review examined four major areas of cognitive therapy including: attention/concentration, learning and memory, executive functioning, and general cognitive rehabilitation approaches. In total, 64 studies were evaluated throughout the four major areas, which provided the evidence-base for 18 conclusions.
Objective: To conduct a systematic review of the rehabilitation literature of moderate to severe acquired brain injuries (ABI) from traumatic and non-traumatic causes.
Methods: A review of the literature was conducted for studies looking at interventions in ABI rehabilitation. The methodological quality of each study was determined using the Downs and Black scale for randomized controlled trials (RCTs) and non-RCTs as well as the Physiotherapy Evidence Database (PEDro) scale for RCTs only.
