- ItemAcesso aberto (Open Access)Atenção visual em crianças com migrânea: um estudo comparativo controlado(Universidade Federal de São Paulo (UNIFESP), 2011-06-29) Villa, Thaís Rodrigues [UNIFESP]; Gabbai, Alberto Alain [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objective: To evaluate the visual attention of children with migraine and compare to the headache free control group. Method: 30 children with migraine, with (n=5) and without aura (n=25), which fulfill the gInternational Headache Society (ICHD-II, 2004) h criteria, 15 female, ages 8 to 12 years and 11 months (average=10.8 }1.5 years), with an average of 5.8 } 3.2 attacks/month, lasting up to 24 hours, and 30 control subjects without headache, 14 female, average age 9,9 }1.3 years. Method of assessment of visual attention: Trail Making Test (TMT) A/B, Letter Cancellation Test, and the computerized test Visual Attention Test . 3rd edition (TAVIS-3) which evaluates reaction time, omission and action errors through subtests of selective (task1), alternate (task2), and sustained attention (task3). Migraine group were evaluated after two days without headache. Exclusion criteria: other systemic diseases, altered neurological examination, psychiatric disorders, learning disorders, epilepsy, head trauma, use of medication (including migraine prophylaxis), and an Intelligence Quotient (IQ) < 80, measured by Wechsler Intelligence Scale 3rd edition. Statistical analysis: Student fs t test and Mann-Whitney fs test, Confidence Interval of 95% (p.0.05). Results: Children with migraine had inferior performance compared to the control group on TMT A (p=0.03) and B (p=0.001), and more action errors on tasks 1 (p=0.032) and 2 (p=0.015) of TAVIS-3, presenting difficulty with selective and alternate attention. Discussion: Attention is a complex neurologic function which depends on structures such as the brain stem, cerebral cortex, and the limbic system and on neurotransmitters such as dopamine and noradrenaline. Conclusion: The neurochemical aspects involved in the physiopathology of migraine and attention mechanisms probably predispose these children to visual attention deficits.

- ItemAcesso aberto (Open Access)Potencial evocado miogênico vestibular em mulheres com migrânea vestibular(Universidade Federal de São Paulo (UNIFESP), 2016-06-30) Morganti, Ligia Oliveira Gonçalves [UNIFESP]; Ganança, Fernando Freitas [UNIFESP]; http://lattes.cnpq.br/0831776469482702; http://lattes.cnpq.br/2395966452922910; Universidade Federal de São Paulo (UNIFESP)Introduction: Vestibular Migraine (MV) is considered the main cause of recurrent spontaneous vertigo. Among the tests of vestibular function evaluation, the vestibular evoked myogenic potential (VEMP) is a relatively new and easy method with recognized clinical practice utility. Objective: To describe the results of cervical and ocular VEMP in women with MV and compare with the responses obtained in normal individuals. Methods: cross-sectional study with women with MV according to Barany Society / International Headache Society 2012-2013 criteria and controls. The tests were performed using tone burst stimulus, with 500 Hz and 1000 Hz, in addition to clicks, used only for cervical VEMP. Results were compared between the two groups and the stimulus type/frequency. Results: The median age of patients was 38 years. The average of onset time of headache was 22.1 years and dizzines 10.32 years. cVEMP: the study group had largest interamplitudes compared to individuals from control group. The asymmetry index was greater in the patient group just for click stimulus. Within each group, the latencies and interamplitudes were larger for tone burst stimulus of 500 Hz, followed by 1000 Hz and click. There was no difference in the asymmetry index, for each different stimulus, in both group. oVEMP: There was no difference between the groups, the values of latencies, interamplitudes and asymmetry indices. Within each group, the latencies and interamplitudes were larger for 500Hz tone burst stimulus. Conclusions: female patients with MV out of disease crisis period, tend to have higher response amplitudes on cVEMP and greater asymmetry index in the cVEMP with Click stimulus when compared to controls. The TB stimulus in frequency of 500 Hz displays response wityh largest interamplitudes and latencies, followed by 1,000 Hz and click in both controls and individuals with MV. There is no difference, in both groups, between the different stimuli, for the asymmetry index values
- ItemAcesso aberto (Open Access)Vestibular migraine: clinical and epidemiological aspects(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2016) Goncalves Morganti, Ligia Oliveira [UNIFESP]; Salmito, Marcio Cavalcante [UNIFESP]; Duarte, Juliana Antoniolli [UNIFESP]; Sumi, Karina Cavalcanti [UNIFESP]; Simoes, Juliana Caminha [UNIFESP]; Gananca, Fernando Freitas [UNIFESP]Introduction: Vestibular migraine (VM) is one of the most often common diagnoses in neurotology, but only recently has been recognized as a disease. Objective: To analyze the clinical and epidemiological profile of patients with VM. Methods: This was a retrospective, observational, and descriptive study, with analysis of patients' records from an outpatient VM clinic. Results: 94.1% of patients were females and 5.9% were males. The mean age was 46.1 years
- ItemAcesso aberto (Open Access)Video-head impulse test em pacientes com migrânea vestibular(Universidade Federal de São Paulo (UNIFESP), 2015-12-18) Salmito, Marcio Cavalcante [UNIFESP]; Ganança, Fernando Freitas [UNIFESP]; http://lattes.cnpq.br/0831776469482702; http://lattes.cnpq.br/8767113872860390; Universidade Federal de São Paulo (UNIFESP)Introdução: a migrânea vestibular (MV) como entidade específica foi descrita em 1999 e sua fisiopatologia ainda não está bem estabelecida. Paralelamente às pesquisas que tentam compreender melhor a MV, houve um aprimoramento de técnicas de análise da função vestibular na prática clínica. O vídeo head impulse test (vHIT) é uma das mais recentes ferramentas para avaliar a função vestibular, medindo o ganho do reflexo vestíbulo-ocular. Objetivo: Avaliar a função vestibular de pacientes com MV por meio do vHIT. Método: estudo transversal do tipo casocontrole com amostras homogêneas em gênero e idade de pacientes com MV pelos critérios da Bárány Society / International Headache Society de 2012-2013 submetidos a vHIT no período intercrise de sua doença. Resultados: foram avaliados 31 pacientes com MV, com predomínio do gênero feminino (90,3%) e idade média de 41 anos. A função vestibular medida pelo valor do ganho foi normal nos dois grupos de paciente. Os valores de ganho para canais horizontais foram iguais entre os dois grupos, porém os valores de ganho para canais verticais foram maiores no grupo com MV (p<0,05). Os pacientes com MV apresentaram mais tontura durante a realização do vHIT que os indivíduos controle (p<0,001). Conclusões: Pacientes com MV apresentam função vestibular normal no período intercrises quando avaliados por vHIT. Os canais verticais, no entanto, apresentam ganhos mais elevados que os ganhos de indivíduos controle. Mais pacientes com MV sentem tontura durante a realização de vHIT do que indivíduos controle.
