The commonest and most widely recognized is the reversible syndrome of hepatic encephalopathy,2 and we will deal with this in some detail. There are also of course many conditions that affect both the liver and the nervous system, Wilsons disease being one of the best known.28 This condition is a genetic disorder of copper metabolism; the abnormal gene is located on chromosome 139 and most of the symptoms seem to be due directly to the deposition of copper in various organs. Patients typically present early with liver disease or later with the neurological syndrome,2 which consists of various subtle neuropsychiatric symptoms such as a change in behaviour or performance at school10 and abnormality of movement.3,4 There are many other conditions where the brain
