Impaired consciousness requires altered cortical function. This can occur either directly from disorders that impair widespread bilateral regions of the cortex or indirectly through effects on subcortical arousal systems. It has therefore long been puzzling why focal temporal lobe seizures so often impair consciousness. Early work suggested that altered(More)
OBJECTIVE We hypothesized that low rates of tissue plasminogen activator (tPA) use are only partially explained by medical considerations, and that biases, beliefs, systems, and uncertainty affect acute stroke decision-making. METHODS We generated a list of factors potentially influential in acute stroke decision-making: uncertainty, patient demographics(More)
We review the case of a young man who developed a constellation of symptoms and signs-bizarre behavior, seizures, abnormal movements, and autonomic instability-that evaded diagnosis at the time of presentation. We use this case to explore the way medical knowledge changes over time. Despite the dramatic advances in our understanding of neurological diseases(More)
We report the case of a pregnant woman treated for acute ischemic stroke and review the literature on acute stroke treatment in pregnancy. To our knowledge, this is the first case reporting the successful use of intravenous tissue plasminogen activator and a stent retriever for acute stroke in pregnancy. We then use this case to consider the way medical(More)
On February 11, 2015, the Canadian Food Inspection Agency announced that a cow born and raised in Alberta had tested positive for bovine spongiform encephalopathy (BSE), commonly known as mad cow disease. BSE is a prion disease of cattle that, when transmitted to humans, produces a fatal neurodegenerative disease known as variant Creutzfeldt-Jakob disease.(More)
