The normal cerebral circulation has the ability to maintain a stable cerebral blood flow over a wide range of cerebral perfusion pressures and this is known as cerebral autoregulation. Autoregulation may be impaired in the injured brain. Closed head injury was induced in 28 Sprague-Dawley rats weighing 400-450 g. Four groups were studied: control and(More)
INTRODUCTION In recent years different neuropsychological batteries have been developed to assess cognitive performance in schizophrenia. However, no test has been validated in Spanish for this purpose. The Barcelona Test has been one of the tests used. This present article has aimed to present a specific neurocognitive battery for schizophrenia by(More)
In a consecutive series of 26 previously operated patients diagnosed with cerebral glioma, magnetic resonance spectroscopy (MRS), 2-((18)F) fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET), and perfusion MRI (MRP), were performed at follow-up to distinguish recurrence from radiation necrosis, and to identify tumour upgrading. Discrepancy(More)

The objective of the study is the analysis of prognostic factors observed in the evolution of 65 patients who presented chronic subdural hematoma surgically evacuated. Morbimortality ratio corresponding to our surgical technique is also presented. A retrospective statistical analysis of epidemiologic, clinic and radiologic factors was performed. Personal(More)
INTRODUCTION Space-occupying cerebellar infarcts (SOCI) make up a subgroup within the ischemic pathologies of the brain which are generally well tolerated clinically and usually respond well to medical treatment. Yet, in some cases, due to their volume and localisation, they can be accompanied by a progressive deterioration that requires surgical treatment.(More)
AIMS To review the literature on cerebral neuroblastomas (CN), including their anatomopathological filiation, clinical characteristics together with those they display in imaging studies, and the different therapeutic options with their prognosis. METHOD Cerebral neuroblastomas belong to the group of primitive neuroectodermal tumours (PNET), also known as(More)
Pain experienced by patients who have syringomyelia associated with Chiari I malformation (SACM) includes headache, cervicalgia and radiculalgia. We studied the correlation of clinical and imaging factors with the evolution of pain and surgical outcome at 12 months. We performed a prospective study of 13 patients who presented with SACM and who underwent(More)
INTRODUCTION The Positive and Negative Syndrome Scale (PANSS) is a widely used instrument for measuring symptomatology in patients with schizophrenia. Numerous studies have analyzed the factorial structure of this scale and have suggested a fivefactor model, namely: negative, positive, excited, anxiety/depression, and disorganized (or cognitive). The latter(More)
