===Syndromes in liver failure===
+====[[Photosensitisation]]====
+====Hepatic Encephalopathy====
−=====Clinical=====
−*non-specific neurological signs (attributed to the retention of ammonia and gamma aminobutyric acid in [[Liver - Anatomy & Physiology|liver]] failure and their effects on the brain)
−**dullness
−**apparent unawareness of surroundings
−**pointless or compulsive movements
−**mania
−**generalised convulsions
−NB: usually soon followed by death
−=====Microscopically=====
−*lesions in the brain vary in expression
−**most species may show myelin degeneration consisting of vacuoles between the grey and white matter
−**the horse may show very little visible neural changes, perhaps an increase in astrocytes
−=====Causes=====
−::[[Liver Developmental - Pathology#Portosystemic shunt|Portosystemic Shunting]]
−::Chronic [[Liver - Anatomy & Physiology|liver]] damage
−*due to ingestion of toxic compounds over a long period of time
−*E.g. [[Liver Toxic - Pathology#ragwort|ragwort]]
