Public Chronic Traumatic Encephalopathy Knowledge: Sources, Accuracy and Confidence.

ABSTRACT: The goal of this study was to examine the general public's level of accuracy and confidence in knowledge of chronic traumatic encephalopathy (CTE), as well as information sources. This study also explored how these factors affected comfort in allowing children to play a high-contact sport. This study utilized online surveys and included 529 participants. Overall, CTE knowledge accuracy was 48.02% (standard deviation = 0.23). Inaccuracies regarding the etiology and diagnosis of CTE were most common, whereas the symptoms and lack of treatments for CTE were more widely known. Despite overall low CTE knowledge accuracy, CTE knowledge confidence was positively correlated with comfort in allowing children to play a high-contact sport (r = 0.199, P ≤ 0.001). Participants identified television/movies followed by web sites and social media as the most utilized CTE information sources. These results further support the need for clinicians and researchers to address misconceptions about CTE.

Utilizing the BAT-LQ to assess TBI incidence in a college student population.

OBJECTIVE: Although the annual number of traumatic brain injuries (TBIs) reported in the US exceeds two million, data suggests that this is an underestimate. The goal of this study was to understand lifetime TBI incidence among a sample of college students. Additionally, this study examined whether a single yes/no question regarding TBI history was sufficient to gather accurate information about TBI incidence in college students. DESIGN: Participants were asked a single TBI question and administered the BAT-LQ. MAIN MEASURES: The BAT-LQ is a screening tool designed to assess for probable lifetime TBIs. RESULTS: Data from 121 participants were analyzed for this study. On the single-question, 24.8% of participants reported experiencing a TBI. However, upon further prompting, 76.8% of all participants reported experiencing a blow to the head accompanied by at least one diagnostic symptom of a TBI, suggesting a probable TBI based on best-practice diagnosis guidelines. CONCLUSION: The results of this study suggest that increased education about TBI is warranted to ensure that individuals receive care for probable TBIs, as many individuals likely lack knowledge about what constitutes a TBI diagnosis. Additionally, the results suggest that a single question may not be sufficient to capture true lifetime TBI incidence.

Behavioral and exercise interventions for sleep dysfunction in the elderly: a brief review and future directions.

PURPOSE: The impact of sleep-related changes and disorders in the geriatric populations are of utmost concern due to health consequences and increased risk of injury as well as injuring others as a result of poor sleep. The purpose of this paper is to provide a brief review of the current state of the literature with regard to sleep, aging, common non-pharmacological interventions, and the potential use of exercise in combination with behavioral interventions. METHODS: Initially, this manuscript focuses on a brief (nonsystematic) review of sleep parameters and physiology that are associated with the aging process. Subsequently, information regarding sleep disorders in the elderly in general, and insomnia in particular are discussed. Last, a brief review of current recommended interventions is provided. RESULTS: The current major nonpharmacological interventions are described including Cognitive Behavioral Therapy for Insomnia (CBT-I). The potential use of exercise as a safe intervention for poor sleep is discussed. Finally, a call is made for increased research that examines the combination of traditional behavioral interventions with exercise.

The effects of emotional states and traits on time perception.

BACKGROUND: Models of time perception share an element of scalar expectancy theory known as the internal clock, containing specific mechanisms by which the brain is able to experience time passing and function effectively. A debate exists about whether to treat factors that influence these internal clock mechanisms (e.g., emotion, personality, executive functions, and related neurophysiological components) as arousal- or attentional-based factors. PURPOSE: This study investigated behavioral and neurophysiological responses to an affective time perception Go/NoGo task, taking into account the behavioral inhibition (BIS) and behavioral activation systems (BASs), which are components of reinforcement sensitivity theory. METHODS: After completion of self-report inventories assessing personality traits, electroencephalogram (EEG/ERP) and behavioral recordings of 32 women and 13 men recruited from introductory psychology classes were completed during an affective time perception Go/NoGo task. This task required participants to respond (Go) and inhibit (NoGo) to positive and negative affective visual stimuli of various durations in comparison to a standard duration. RESULTS: Higher BAS scores (especially BAS Drive) were associated with overestimation bias scores for positive stimuli, while BIS scores were not correlated with overestimation bias scores. Furthermore, higher BIS Total scores were associated with higher N2d amplitudes during positive stimulus presentation for 280 ms, while higher BAS Total scores were associated with higher N2d amplitudes during negative stimuli presentation for 910 ms. DISCUSSION: Findings are discussed in terms of arousal-based models of time perception, and suggestions for future research are considered.
