The Epworth Sleepiness Scale (ESS) is a largely wide used scale for sleepiness assessment. Measurement properties are studied in a sample of Portuguese adults, using different statistical procedures. The sample consisted of 222 Portuguese adults (97 men and 125 women) with a mean age of 42 years old (SD = 12.5), 46 of which had obstructive sleep apnea (OSA)(More)
BACKGROUND The consequences of alcohol dependence are severe and may range from physical disease to neuropsychological deficits in several cognitive domains. Alcohol abuse has also been related to brain dysfunction specifically in the prefrontal cortex. Conventional neuropsychological interventions (paper-and-pencil cognitive stimulation training) have a(More)
The consequences of alcohol dependence syndrome are severe, ranging from physical diseases to neuropsychological deficits in several cognitive domains. Alcohol abuse has also been related to brain dysfunction specifically in the prefrontal cortex. We assessed these deficits and the effects of traditional (pen-and-paper) and novel (mobile technology)(More)
Craving is a strong desire to consume that emerges in every case of substance addiction. Previous studies have shown that eliciting craving with an exposure cues protocol can be a useful option for the treatment of nicotine dependence. Thus, the main goal of this study was to develop a virtual platform in order to induce craving in smokers. Fifty-five(More)
The authors present the case of an 11-year-old boy with pharyngitis, treated with amoxicillin, that worsened on day 7, with cough, high fever and refusal to eat. Lethargy and respiratory distress were noted. Based on radiographic findings of bilateral infiltrates he was diagnosed with pneumonia and started on intravenous ampicillin and erythromycin. Two(More)
BACKGROUND Heroin addiction has a negative impact on cognitive functions, and even recovering addicts suffer from cognitive impairment. Recent approaches to cognitive intervention have been taking advantage of what new technologies have to offer. OBJECTIVES We report a study testing the efficacy of a serious games approach using tablets to stimulate and(More)
Acquired brain impairments are responsible for cognitive dysfunctions that affect daily life activities. Promoting cognitive exercise through ecologically-based interactive media such as virtual reality is an emerging option. Although the first step towards ecological ways to stimulate cognitive functions has been given, assessment still relies on(More)
Community dynamics is one of the strongest potentials for ubiquitous computing. This article presents an evaluation framework for ubiquitous digital entertainment within the social context. The article analyzes the overlapping evaluation models for online social interaction, social adaptability, social playability, commonly used on digital game evaluations,(More)
The elderly population is growing fast mainly in the industrialized countries. Ageing is associated with different morbidities including cognitive impairments that limit the ability of these individuals to carry out their daily life activities. This study reports on the development of a computer-assisted approach for cognitive assessment in the elderly. The(More)
Alcohol abuse impacts on cognitive functioning. We report a test of a cognitive stimulation intervention on patients recovering from alcohol dependence syndrome. 169 patients were split into 2 groups (cognitive stimulation and controls). Patients in cognitive stimulation and engaged in a 10-session protocol with cognitive exercises in the form of serious(More)
