A Reversible Event Leading to Lifestyle Reversion: About a Case of PRES
Pereira, Sofia; Almeida, Ana Catarina; Mateus, Hélia; André, RuiThe posterior reversible encephalopathy syndrome (PRES) is a heterogeneous clinical-radiological characterized by a combination of encephalopathy, altered mental status, epileptic seizures, visual disturbances, headache, and focal neurologic signs. Other neurologic deficits, such as ataxia, may occur. PRES can be found in a nonposterior distribution, mainly in watershed areas, including the frontal, inferior te...
EpiReumaPt: how to perform a national population based study - a practical guide
Gouveia, Nélia; Rodrigues, Ana M.; Ramiro, Sofia; Machado, Pedro; Costa, Leonor Pereira da; Mourão, Ana Filipa; Silva, Inês; Rego, Tânia; Laires, PedroBACKGROUND: The aim of this article was to describe and discuss several strategies and standard operating procedures undertaken in the EpiReumaPt study - which was the first Portuguese, national, cross-sectional population-based study of Rheumatic and Musculoskeletal Diseases (RMD). METHODS: The technical procedures, legal issues, management and practical questions were studied, analyzed and discussed with rele...
Specific impairment of visual spatial covert attention mechanisms in Parkinson'...
Sampaio, Joana; Campos, Elzbieta Bobrowicz; André, Rui; Almeida, Inês; Faria, Pedro; Januário, Cristina; Freire, António; Castelo-Branco, MiguelVisual deficits in early and high level processing nodes have been documented in Parkinson's disease (PD). Non-motor high level visual integration deficits in PD seem to have a cortical basis independently of a low level retinal contribution. It is however an open question whether sensory and visual attention deficits can be separated in PD. Here, we have explicitly separated visual and attentional disease rela...
Cerebral venous thrombosis: retrospective analysis of 49 cases.
Santos, Gonçalo Roque; André, Rui; Pereira, Sara Leonor; Parreira, Tiago; Machado, EgídioCerebral Venous Thrombosis (CVT) is a rare and potentially life-threatening disease, accounting for about 0.5% of stroke cases. However, it is believed to be an underdiagnosed condition. Early diagnosis requires a high degree of suspicion and appropriate use of imaging modalities.Imagiological and clinical characterization of CVT cases diagnosed at our hospital from 2004 to 2007.This study was a retrospective, ...
Devic's disease.
Peixoto, Irina; Ermida, Vera; Torres, Ana; Aparício, Maria Inês; André, Rui; Caldas, JorgeDevic's disease, also known as Neuromyelitis Optica, is a demyelinating disease of the central nervous system, with selective involvement of the spinal cord and optic nerves. The authors describe a clinical case of acute myelitis, initially approached in the context of a nonspecific syndrome gripal, with subsequently sudden bilateral amaurosis, which leads to the diagnosis hypotesis of Devic's disease, a diseas...
The role of the basal ganglia in implicit contextual learning: a study of Parki...
van Asselen, Marieke; Almeida, Inês; André, Rui; Januário, Cristina; Gonçalves, António Freire; Castelo-Branco, MiguelImplicit contextual learning refers to the ability to memorize contextual information from our environment. This contextual information can then be used to guide our attention to a specific location. Although the medial temporal lobe is important for this type of learning, the basal ganglia might also be involved considering its role in many implicit learning processes. In order to understand the role of the ba...
