Hepatic encephalopathy
Hepatic encephalopathy is a neurological syndrome caused by the liver's failure to clear toxins, especially ammonia, from the blood. It occurs with portosystemic shunts and severe liver disease. Animals show dullness, circling, head pressing, drooling, and seizures, often worsening after meals. Management targets reducing toxin production and treating the underlying liver disorder.
