Severe HE, grades 3 and 4 West Haven criteria, should prompt attention to airway protection, and endotracheal intubation ought to be considered. The diagnosis of overt HE is clinical and supported by the presence of a wide spectrum of global neurologic deficits. A smartphone application that evaluates psychomotor speed and cognitive alertness has been developed and validated as a point-of-care screening tool for covert HE: EncephalApp Stroop. These tests, however, are not applicable in routine clinical practice and usually require consultation with a specialist. The psychometric hepatic encephalopathy score is regarded as the gold standard, but additional assessments include the number connection test, computerized tests such as the inhibitory control test, the cognitive drug research battery, and electroencephalogram. Specialized testing is necessary to establish a diagnosis of covert HE. In contrast, overt HE is characterized by clinical findings of HE ranging from subtle changes in orientation and presence of asterixis to hepatic coma (grades 2 to 4 per West Haven criteria). Although the West Haven criteria are widely used for grading the severity of HE ( Table 8), current guidelines recommend using three additional axes to classify HE based on the etiology, time course, and presence or absence of a precipitating factor ( Table 9).Д¬overt HE is considered preclinical and encompasses minimal HE (features of HE that are only diagnosed by specialized neuropsychiatric testing) and grade 1 HE as per West Haven criteria. The prevalence of HE varies depending on the clinical subtype and the severity of liver disease, with cumulative prevalence rates of up to 80% for covert HE and 30% to 40% for overt HE in patients with cirrhosis. Features of HE may be subclinical (covert) or clinically evident (overt) and include a wide range of neuropsychiatric signs and symptoms. There is continuing controversy about its exact pathogenesis, but gut-derived toxins, including ammonia, are clearly implicated. Hepatic encephalopathy (HE) is a clinical syndrome of reversible neuropsychiatric impairment of varying severity.

If an explicit setting is given for ColorRules, MeshShading, or ContourShading, it is used in preference to the setting for ColorFunction.Д¬ite this as: Wolfram Research (1991), ColorFunction, Wolfram Language function, (updated 2012).In 3D graphics, ColorFunction by default specifies diffuse colors for surfaces.Combinations of directives can be specified using Directive.It can also return Opacity, as well as Glow and Specularity.The function specified by ColorFunction must return color directives such as RGBColor and Hue or named colors such as Red and Blue.The list of possible color function names is given by ColorData.ColorFunction->' name' is equivalent to ColorFunction-> ( ColorData & ) where the slot used is as follows: Plot, ListPlot, etc.: #2 ( ) ArrayPlot, ReliefPlot: #1 ( ) ContourPlot, DensityPlot, etc.: #1 ( ) ContourPlot3D, etc.: #4 ( ) Plot3D, etc.: #3 ( ).With ColorFunctionScaling-> False, original unscaled values are used.With the usual default setting ColorFunctionScaling-> True, all arguments supplied to func are scaled to lie in the range 0 to 1.Plot3D, ListPlot3D, ListSurfacePlot3D, ListPointPlot3D With ColorFunction-> func, the arguments supplied to func are as follows:.
