The amount of knowledge on human consciousness has created a multitude of viewpoints and it is difficult to compare and synthesize all the recent scientific perspectives. Indeed, there are many definitions of consciousness and multiple approaches to study the neural correlates of consciousness (NCC). Therefore, the main aim of this article is to collect data on the various theories of consciousness published between 2007–2017 and to synthesize them to provide a general overview of this topic. To describe each theory, we developed a thematic grid called the dimensional model, which qualitatively and quantitatively analyzes how each article, related to one specific theory, debates/analyzes a specific issue. Among the 1130 articles assessed, 85 full texts were included in the prefinal step. Finally, this scoping review analyzed 68 articles that described 29 theories of consciousness. We found heterogeneous perspectives in the theories analyzed. Those with the highest grade of variability are as follows: subjectivity, NCC, and the consciousness/cognitive function. Among sub-cortical structures, thalamus, basal ganglia, and the hippocampus were the most indicated, whereas the cingulate, prefrontal, and temporal areas were the most reported for cortical ones also including the thalamo-cortical system. Moreover, we found several definitions of consciousness and 21 new sub-classifications.

To comprehensively identify the determinants of quality of life (QoL) in a population study sample of persons aged 18–50 and 50+. In this observational, cross-sectional study, QoL was measured with the WHOQOL-AGE, a brief instrument designed to measure QoL in older adults. Eight hierarchical regression models were performed to identify determinants of QoL. Variables were entered in the following order: Sociodemographic; Health Habits; Chronic Conditions; Health State description; Vision and Hearing; Social Networks; Built Environment. In the final model, significant variables were retained. The final model was re-run using data from the three countries separately. Complete data were available for 5639 participants, mean age 46.3 (SD 18.4). The final model accounted for 45% of QoL variation and the most relevant contribution was given by sociodemographic data (particularly age, education level and living in Finland: 17.9% explained QoL variation), chronic conditions (particularly depression: 4.6%) and a wide and rich social network (4.6%). Other determinants were presence of disabling pain, learning difficulties and visual problems, and living in usable house that is perceived as non-risky. Some variables were specifically associated to QoL in single countries: age in Poland, alcohol consumption in Spain, angina in Finland, depression in Spain, and self-reported sadness both in Finland and Poland, but not in Spain. Other were commonly associated to QoL: smoking status, bodily aches, being emotionally affected by health problems, good social network and home characteristics. Our results highlight the importance of modifiable determinants of QoL, and provide public health indications that could support concrete actions at country level. In particular, smoking cessation, increasing the level of physical activity, improving social network ties and applying universal design approach to houses and environmental infrastructures could potentially increase QoL of ageing population.

The aim of this study is to evaluate the burden of caregivers of patients with disorders of consciousness (DOCs), considering psychosocial difficulties, health condition and financial aspects. This is an observational multi-centre study. Four hundred and eighty-seven participants were assessed using the Caregiver Needs Assessment, Family Strain Questionnaire, Short Form 12, Spielberger State Trait Anxiety Inventory-Y, Beck Depression Inventory, Prolonged Grief Disorder Questionnaire and Coping Orientations to Problem Experiences. The sample had lower scores both in Physical (M = 49.85, SD = 7.66) and Mental (M = 39.37, SD = 12.90) health and a higher level of anxiety (p < 0.001) in comparison to the Italian normative sample. More than half of the sample manifested a high level of depressive symptoms (59.5%) and 27.6% satisfied criteria for Prolonged Grief Disorder. This sample reported needs to know the disease of their beloved, high needs for information and communication, several problems in social involvement and in emotional burden. The most frequently adopted coping strategies are acceptance, turning to religion, positive reinterpretation and planning. Finally, 40.2% of caregivers report to earn a net income of less than 17 000 euros per year. These results showed a high burden related to providing care to patients with DOCs. This study sets the scene to plan comprehensive support strategies for caregivers in order to diminish level of burden.

The aim of this study was to assess the impact of stroke on health-related quality-of-life (HRQoL) and disability, the relationships between the two constructs, and to what extent these two constructs are affected when perceived health state changes. The World Health Organization Disability Assessment Schedule (WHO-DAS II) and the 36-Item Short-Form Health Survey (SF-36) were administered via mail to a sample of adult stroke survivors. Comparison against normative Italian values was made using one-sample t test. SF-36 and WHO-DAS II scores were compared between employed and unemployed patients and between patients self-reporting improved, unchanged, and decreased health state using analysis of variance with least significant difference post hoc test. The relationships between SF-36 and WHO-DAS II were assessed using Pearson correlation. A total of 111 patients were enrolled. The SF-36 and WHO-DAS II scores of stroke patients were worse in comparison with Italian normative values. Moderate to strong correlations between all scales and the summary score of WHO-DAS II and SF-36 were found: The worse the disability is, the lower the HRQoL. Patients reporting worse health status in the previous year reported higher levels of disability and lower HRQoL. Employed persons had higher HRQoL and lower disability levels. The generic HRQoL instrument and disability schedule used in this study demonstrated strong relationship between these two dimensions. It also gave a more detailed picture of the aspects of disability and HRQoL that are most relevant for the persons after stroke and that should be studied further in the future research.
