It can be due to direct injury to the brain, or illness remote from ...
The exact definition of "rapid" is somewhat debatable, and different sub-divisions exist, which are based on the time from onset of first hepatic symptoms to onset of encephalopathy. One scheme defines "acute hepatic failure" as the development of encephalopathy within 26 weeks of the onset of any hepatic symptoms.
In ALF, hepatic encephalopathy leads to cerebral edema, coma, brain herniation, and eventually death. Detection of encephalopathy is central to the diagnosis of ALF. It may vary from subtle deficit in higher brain function (e.g. mood, concentration in grade I) to deep coma (grade IV). Patients presenting as acute and hyperacute liver failure ...
It was originally introduced in the screening for dementia, but has also found application in other situations, [3] such as hepatic encephalopathy. [ 4 ] References
It may also present with Hepatic encephalopathy (brain dysfunction due to liver failure) causing symptoms such as confusion, decreased levels of consciousness, or asterixis, [5] (a characteristic flapping movement when the wrist is extended indicative of hepatic encephalopathy).
From November 1995 to November 1996 in France, a national survey of pediatric departments for children under 15 years of age with unexplained encephalopathy and a threefold (or greater) increase in serum aminotransferase and/or ammonia led to the identification of nine definite cases of Reye syndrome (0.79 cases per million children). Eight of ...
This diagnosis is classified as a permanent vegetative state some months (three in the US and six in the UK) after a non-traumatic brain injury or one year after a traumatic injury. The term unresponsive wakefulness syndrome may be used alternatively, [ 2 ] as "vegetative state" has some negative connotations among the public.
