ABSTRACT
The Brazilian Stroke Society constituted a committee composed by specialists from different areas of Brazil that emitted a viewpoint called [quot ]National Opinion[quot ], written similar to the consensus pattern. The study purpose is to guide and offer subsidies for diagnosis and therapeutical plans for different situations in cerebrovascular diseases. The current article analyses [quot ]neuroprotective agents in stroke[quot ], discussing the level of evidence for the use of potential neuroprotective drugs and ongoing clinical trials.
Com finalidade de orientar e oferecer subsídios para a conduta diagnóstica e terapêutica em diferentes situações dentro das doenças cerebrovasculares, a Sociedade Brasileira de Doenças Cerebrovasculares (SBDCV) constituiu um comitê composto por neurologistas de diferentes áreas do Brasil que emitiram um parecer, denominado "Opinião Nacional", redigido nos moldes dos consensos. O presente artigo analisa a "neuroproteção no acidente vascular cerebral" discutindo o nível de evidência para o uso de drogas de potencial ação neuroprotetora e ensaios clínicos em andamento.

Creutzfeldt-Jakob disease (CJD) is a transmissible disease of the nervous system causatively related to the presence of an abnormal prion protein, with dementia, myoclonic jerks, and periodic EEG activity. Fourteen patients (7 females and 7 males) ranging from 26 to 76 years of age (median 59 years) were evaluated between 1974 and 1995 at the Neurologic Clinic of Sao Paulo University School of Medicine. The average duration of the disease was 12 months (3.5 - 34 months). Early clinical findings were: behaviour changes in 7 patients, dementia in 4, visual disturbances in 4, vertigo in 2, tremor in 9, and dystonia in one. Advanced symptoms were dementia and myoclonus in all patients. Pyramidal tract dysfunction was found in 6, cerebellar ataxia in 2, seizures in 3, nystagmus and vertigo in 4, and peripheral nervous system involvement in 2. Atypical clinical forms were found in 5 patients. Periodic EEG activity was found in 10 patients. Cerebrospinal fluid evaluation showed pleocytosis in 1 patient, higher protein content in 2, and higher gamma globulin level in 2. In 10 patients anatomopathological evidence in the central nervous system confirmed the clinical diagnosis by presenting with status spongiosus. All except one patient presented with the sporadic form of the disease.
