Gestão das cefaleias em Portugal: consenso das Sociedades Portuguesas de cefale...
Gil-Gouveia, Raquel; Parreira, Elsa; Martins, Isabel Pavão; Luzeiro, Isabel; Pereira, Raúl Marques; Plácido, Madalena; Palavra, FilipeAs cefaleias são uma causa significativa de incapacidade a nível global, com a enxaqueca a ocupar o segundo lugar entre as doenças com mais anos vividos com incapacidade. A maioria dos doentes com cefaleias, incluindo enxaqueca, podem e devem ser diagnosticados, tratados e acompanhados eficazmente nos cuidados de saúde primários. Isso não só reduz a incapacidade associada a estas patologias, mas também previne ...
Uncovering longitudinal changes in the brain functional connectome along the mi...
Esteves, Inês; Fouto, Ana R.; Ruiz-Tagle, Amparo; Caetano, Gina; Nunes, Rita G.; Silva, Nuno A. da; Vilela, Pedro; Martins, Isabel PavãoChanges in large-scale brain networks have been reported in migraine patients, but it remains unclear how these manifest in the various phases of the migraine cycle. Case-control fMRI studies spanning the entire migraine cycle are lacking, precluding a complete assessment of brain functional connectivity in migraine. Such studies are essential for understanding the inherent changes in the brain of migraine pati...

Working memory during spontaneous migraine attacks: an fMRI study
Ruiz-Tagle, A.; Figueiredo, Patrícia; Pinto, Joana; Vilela, Pedro; Martins, Isabel Pavão; Gil-Gouveia, RaquelObjective: To investigate the neural correlates of working memory during a spontaneous migraine attack compared to the interictal phase, using functional magnetic resonance imaging (fMRI). Background: Cognitive disturbances are commonly observed during migraine attacks, particularly in the headache phase. However, the neural basis of these changes remains unknown. Methods: In a fMRI within-subject test-retest d...
Recurrent syncope during migraine attacks
Dias Da Costa, Mariana; Nunes Vicente, Beatriz; Dourado Sotero, Filipa; Martins, Isabel PavãoMigraine is a cyclic condition with attacks consisting mainly of intense headaches, sensory intolerance, and nausea or vomiting. Loss of consciousness during attacks is often attributed exclusively to a neurally mediated reflex to pain, although it may also be due to migraine's autonomic impairment, with cardiac conduction abnormalities, probably in relation to a degree of reduced sympathetic function. We repor...
Locations of objects are better remembered than their identities in naturalisti...
Coco, Moreno I.; Maruta, Carolina; Martins, Isabel Pavão; Sala, Sergio DellaObjective: Retaining the identity or location of decontextualized objects in visual short-term working memory (VWM) is impaired by healthy and pathological ageing, but research remains inconclusive on whether these two features are equally impacted by it. Moreover, it is unclear whether similar impairments would manifest in naturalistic visual contexts. Method: 30 people with mild cognitive impairment (MCI) and...
Cranial autonomic symptoms and neck pain in differential diagnosis of migraine
Vicente, Beatriz Nunes; Oliveira, Renato; Martins, Isabel Pavão; Gil-Gouveia, RaquelCranial autonomic symptoms and neck pain have been reported to be highly prevalent in migraine, although they are rarely considered in clinical evaluation. The aim of this review is to focus on the prevalence, pathophysiology, and clinical characteristics of these two symptoms, and their importance in the differential diagnosis between migraines and other headaches. The most common cranial autonomic symptoms ar...
Altered functional connectivity in a sensorimotor-insular network during sponta...
Araújo, Raquel Pestana; Figueiredo, Patricia; Pinto, Joana; Vilela, Pedro; Martins, Isabel Pavão; Gil-Gouveia, RaquelBackground: Previous functional magnetic resonance imaging studies have identified brain-connectivity alterations across multiple regions in people with migraine when compared to healthy controls. Few studies have focused on such changes throughout the different phases of the migraine cycle. We aimed to investigate functional connectivity during spontaneous occurring episodic migraine attacks, in comparison to ...
Profile of cognitive impairment in late-stage Parkinson's disease
Sousa, Catarina Severiano e; Fabbri, Margherita; Godinho, Catarina; Simões, Rita Moiron; Chendo, Inês; Coelho, Miguel; Martins, Isabel PavãoIntroduction: The profile of cognitive impairment associated with the late stages of Parkinson's disease (LSPD) is rarely reported. Its characterization is necessary to better understand the cognitive changes that occur as the disease progresses and to better contribute to its management.
Clinical presentation and neural correlates of stroke‐associated spatial delusions
Alves, Pedro Nascimento; Fonseca, Ana Catarina; Melo, Teresa Pinho e; Martins, Isabel PavãoBackground and purpose: Incongruent beliefs about self-localization in space markedly disturb patients' behavior. Spatial delusions, or reduplicative paramnesias, are characterized by a firm conviction of place reduplication, transformation, or mislocation. Evidence suggests they are frequent after right hemisphere lesions, but comprehensive information about their clinical features is lacking. Methods: We pros...
