The MSQ-BR has adequate internal consistency and test-retest reliability. The MSQ-BR insomnia has adequate internal consistency for use as a separate application. However, the MSQ-BR hypersomnia demonstrated only moderate internal consistency for use as a separate application. Our intention was not to introduce modifications to the questionnaire, but to evaluate the reliability of total MSQ-BR and its subscales. Others studies are needed to assess the consistency of MSQ compared to other instruments.

Objective: To determine the prevalence, characteristics and impact of headache among university students. Method: The criteria established by the International Headache Society were used to define the primary headache subtypes and the Migraine Disability Assessment Questionnaire (MIDAS), to assess the disability. The students were then grouped into six categories: [1] .5% had at least one headache episode in the last three months. Regarding disability, there was a significant difference between the headache types (p<0.0001). In the post-hoc analysis, migraine was the headache type with most reported disability. Conclusion: Headache is a highly prevalent condition among the students at the University of Caxias do Sul. This disease may have a major impact on the students' lives and in some cases, ultimately lead to educational failure. Key words: disability, headache, prevalence, young population.

-Objective: To evaluate the knowledge about stroke in Caxias do Sul. Method: A closed-ended, self-administered questionnaire was used to assess the knowledge about stroke among residents of Caxias do Sul. In order to verify variables associated to lack of knowledge we defined three main end points: (1) the inability to recognize that stroke is a disease that affects the brain; (2) insufficient knowledge of risk factors; (3) insufficient knowledge of signs and symptoms of acute stroke. Results: A total of 952 subjects answered the questionnaire. Lower income and lower educational level were independent factors associated to inability to recognize that stroke affects the brain. Lower income and being under 50 years old were independent risk factors to lack of knowledge concerning stroke risk factors. Lower educational level was the unique risk factor for insufficient knowledge about stroke warning signs. Conclusion: There is a lack of knowledge about stroke in Caxias do Sul. People with lower socioeconomic status and lower education level should be the targets of educational campaigns.KEY WORDS: stroke, knowledge, risk factors, warning signs, general population. Avaliação de fatores de risco de doença cerebrovascular no sul do BrasilResumo -Objetivo: Avaliar o conhecimento sobre doença cerebrovascular em Caxias do Sul. Método: Um questionário auto-administrado, com questões objetivas, foi utilizado para avaliar o conhecimento sobre doença cerebrovascuar em residentes de Caxias do Sul.

Stroke is a major public health problem and the leading cause of mortality in Brazil 1,2 . Nevertheless, it is still a neglected disease in this country, where a great number of patients does not get the specific treatment because of the delay in the diagnosis and the absence of the recombinant tissue plasminogen activator (rt-PA) in the public hospitals network 2-4 .

Depression and anxiety are mood disorders that are commonly related to chronic illnesses. The overall frequency in hospitalized patients has an index of variation between 20 and 60% 1-3 , and they are not recognized in one third of patients 4 . Their frequency can be higher in patients without mood disorders presenting symptoms caused by physical illness or preoperative anxiety, which range from 11 to 80% in adults 5 . This variation is related to the sociodemographic characteristics of the population studied, type of disease, degree of involvement, chronicity, and variability of the methodological definitions used in the studies, such as the cutoff point, the search tools, and the case definition. The literature offers different scales for the assessment of anxiety and depression, such as Beck Depression Inventory (BDI), Hospital Palavras-Chave: cirurgia da coluna, depressão,

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.
