Abstract
The liver is a vital organ responsible for a number of
physiological processes, including the synthesis of essential
proteins, the handling of various nutrients, and the metabolism of
drugs and other compounds (e.g., ammonium ions).
Subclinical Hepatic Encephalopathy (SHE) features in
30-84% of patients with cirrhosis of the liver. No gold standard
exists for the diagnosis of this complex neuropsychiatric
syndrome.
Psychometric tests have gained most significance
because they are easy to perform and demonstrate high
sensitivity. Electrophysiological methods such as EEG, visual
evoked potentials, P300 and brain imaging and spectroscopic
techniques currently have a secondary and complementary role.
Anxiety is a common experience in chronic illness but
for many with end-stage liver disease it is also associated with
the stress of waiting for a donor organ to become available.
Quality of life, work, family and social roles are all impaired
and these losses may also contribute to depression.
Patients with hepatitis have symptoms of anxiety and
depression to a certain degree
