Throughout the centuries, scientific observers have endeavoured to extend their knowledge of the interrelationships between the brain and its regulatory control of human emotions and behaviour. Since the time of physicians such as Aristotle and Galen and the more recent observations of clinicians and neuropathologists such as Broca, Papez, and McLean, the field of affective neuroscience has matured to become the province of neuroscientists, neuropsychologists, neurologists, and psychiatrists. It is accepted that the prefrontal cortex, amygdala, anterior cingulate cortex, hippocampus, and insula participate in the majority of emotional processes. New imaging technologies and molecular biology discoveries are expanding further the frontiers of knowledge in this arena. The advancements of knowledge on the interplay between the human brain and emotions came about as the legacy of the pioneers mentioned in this field. The aim of this paper is to describe the historical evolution of the scientific understanding of interconnections between the human brain, behaviour, and emotions.
Objective: The purpose of this study is to review the main postpartum screening tools currently used in terms of their ability to screen for postnatal depression. Furthermore, the cultural characteristics of depressive postpartum symptomatology are examined. Method: A systematic literature search was conducted for the period 1987-2009, using the Medline electronic database for the following keywords: postpartum depression and postnatal depression. These terms were combined with: assessment, screening and psychometric tools. Results: Of the four screening tools reviewed and compared, the Edinburgh Postnatal Depression Scale (EPDS) and the Postpartum Depression Screening Scale (PDSS) presented substantial sensitivity and specificity as screening tools. However, none of the instruments could be rated flawless when applied to different cultural contexts. Conclusions: In addition to the EPDS, a new generation of instruments is currently available. Supplementary research is needed to substantiate their use as screening tools in general practice. Additional studies are needed to adapt and test instruments to detect postnatal depression within a wider range of languages and cultures.
OBJECTIVE: To evaluate the awareness on epilepsy among undergraduate health care students in a private university. METHODS: A self-administered questionnaire about epilepsy was applied to 417 students at Universidade de Caxias do Sul. The answers were analyzed in two groups: group 1, medical and nursing students; group 2, psychology, physiotherapy and nutrition students. RESULTS: Most of the students were familiar with the disease. Although many of them recognize brain disease as a cause of seizure, it was observed that a quarter of them linked epilepsy with mental disease. Besides, a relevant portion of the sample presents mistaken attitudes on seizure management. CONCLUSION: There is lack of information on epilepsy among these students. The students and the health care professionals are important vectors of information. Therefore, further discussion on this subject is necessary in health care training to demystify some aspects concerning the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
