Delirium is a term used variously to characterize a change in behavior. Neurologists most often use the term to describe a patient who has acutely developed a hyperactive agitated state. In many patients, agitation and overactivity are explained by toxic and metabolic factors and infections. Lesions, especially strokes, in some brain regions have been reported to cause sudden agitation and a hy...

BACKGROUND Postoperative cognitive dysfunction (POCD) affects a significant number of patients and may have serious consequences for quality of life. Although POCD is most frequent after cardiac surgery, the prevalence of POCD after noncardiac surgery in older patients is also significant. The risk factors for POCD after noncardiac surgery include advanced age and preexisting cognitive impairme...

OBJECTIVES To determine the relation between delirium in critically ill patients and their outcomes in the short term (in the intensive care unit and in hospital) and after discharge from hospital. DESIGN Systematic review and meta-analysis of published studies. DATA SOURCES PubMed, Embase, CINAHL, Cochrane Library, and PsychINFO, with no language restrictions, up to 1 January 2015. ELIGI...

of impaired attention that fluctuates, together with impaired cognition and/or altered consciousness, perceptual disturbances and behaviour. It may be the only sign of serious medical illness in an older person and should be urgently assessed. Misdiagnosis of delirium may have dire consequences. 2 Better prevention and treatment are needed to avoid the poor outcomes that result from delirium, e...

For integrable equations which can be solved by the Inverse Scattering Transform, there exist Bäcklund transformations (BTs) [1]. These transformations were first discovered for the Sine-Gordon equation at the end of the 19th century. Usually they are treated as nonlinear superpositions, which allow one to create new solutions of a nonlinear evolution equation from a finite number of known solu...

OBJECTIVE The role of a deficiency of vitamin B1 in the development of alcoholic complaints is confined to the case of the Wernicke-Korsakov syndrome. Findings concerning a deficiency of thiamine in alcoholics in comparison with normal persons are contradictory and there are no differentiated tests in the case of delirium tremens. In this study the vitamin B1 absorption in patients with deliriu...

Introduction Chlormethiazole is a sedative and hypnotic with marked anti-convulsant properties. It is widely used in the treatment of states characterized by convulsions and agitation, including delirium tremens. Although rarely causing side effects, the drug has been shown to depress the respiratory centre (Lechat, 1966) and toxic interactions with alcohol have been found in animals (Vapaatalo...

Dynamic texture (DT) is an extension of texture to the temporal domain. How to segment DTs is a challenging problem. In this paper, we address the problem of segmenting DT into disjoint volumes in an unsupervised way. DTs might be different from their spatial mode (i.e., appearance) and/or temporal mode (i.e., motion field). To this end, we develop a framework based on the appearance and motion...
