Neurologic dysfunction characterised by Hepatic Encephalopathy (HE) and cerebral oedema are the most dramatic presentations of Acute Liver Failure (ALF) and signify poor outcome. Improved critical care and wider availability of emergency Liver Transplantation (LT) has improved survivability in ALF. In most cases absence of clinically overt encephalopathy after spontaneous recovery from ALF or after LT is thought to indicate complete neurologic recovery. Recent data suggests that neurologic recovery may not always be complete. Instances of persistent neurologic dysfunction as well as neuropsychiatric abnormalities are now being recognised and warrant active follow up of these patients. Although evidences irreversible neurologic damage is uncommon after ALF, neuropsychiatric disturbances are not uncommon. Complex pathogenesis is involved in neurocognitive disorders seen after many other conditions including LT that require critical care. Structural damage and persistent neurological abnormalities seen after ALF are more likely to be related to cerebral edema, raised intracranial tension and cerebral hypoxemia, while neurocognitive dysfunctions may be a part of a wider spectrum of disorders commonly seen among those who recover from any critical illness
