The present study was composed of two parts examining the clinical utility of the Delis-Kaplan Executive Function System (D-KEFS) Verbal Fluency and Color-Word subtests in traumatic brain injury (TBI). In the first part, the performance of 128 outpatients with mild to severe TBI on the Verbal Fluency and Color-Word subtests was examined in relation to two primary indicators of TBI severity: length of coma and the presence of intracranial lesions on neuroimaging through regression analysis. After controlling for education, ethnicity, and complicating premorbid and comorbid factors, length of coma predicted performance on the Color-Word Inhibition/Switching subtest, whereas the presence of diffuse lesions was related to Verbal Fluency Category Switching performance...

Cysticercosis and sparganosis are not uncommon parasitic infections in the developing world. Central nervous system infection by both cestodes can present with neurological signs and symptoms, such as seizure and mass effect, including brain hernia. Early detection and accurate diagnosis can prevent a fatal outcome. Histological examinations of brain tissues can confirm the diagnosis of cerebral cysticercosis, which differs from sparganosis by the presence of a cavitated body. We report here a case of cerebral cysticercosis which has the similar clinical and imaging findings as sparganosis...

BACKGROUND: Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation...

Examining task-free functional connectivity (FC) in the human brain offers insights on how spontaneous integration and segregation of information relate to human cognition, and how this organization may be altered in different conditions, and neurological disorders. This is particularly relevant for patients in disorders of consciousness (DOC) following severe acquired brain damage and coma, one of the most devastating conditions in modern medical care. We present a novel data-driven methodology, connICA, which implements Independent Component Analysis (ICA) for the extraction of robust independent FC patterns (FC-traits) from a set of individual functional connectomes, without imposing any a priori data stratification into groups...

Biomarkers provide critical mechanistic insights to key biologic processes that occur during cerebral ischemia which, when carefully applied, can improve clinical decision-making in acute stroke management. The translation of a blood-based biomarker in ischemic stroke to clinical practice is challenging, in part, due to the complexity of ischemic stroke pathogenesis and the presence of a blood-brain barrier that restricts the release of brain-specific markers into the circulation. The pathologic and clinical aspects of ischemic stroke are described in this review, where a non-exhaustive list of biomarkers that interrogate different aspects of ischemic stroke such as oxidative damage, inflammation, thrombus formation, cardiac function and brain injury are described...
