The disease can progress well if detected and treated early.
1. What is hepatic encephalopathy?
Hepatic encephalopathy is a buildup of toxins in the blood that causes impaired brain function. The cause of this condition is when the liver cannot remove enough toxins from the blood. Damaged liver function is less able to remove these toxins causing them to build up in the blood and travel to other organs.Hepatic encephalopathy develops when toxins enter the brain and damage brain cells causing physical and psychological symptoms. People with hepatic encephalopathy often experience disturbances in consciousness, behavior, and coma caused by liver dysfunction.
2. Symptoms
Patients will experience different severe and mild symptoms, this depends on the cause of the liver damage and the extent.Mild symptoms, patients may experience such as:
Difficulty in limb movements Forgetfulness, confusion

Lethargy, slow movement Difficulty in pronunciation Restlessness, anxiety The mind is no longer clear, memory is poor Convulsion Hepatic encephalopathy is divided into 3 types, based on the cause of the disease:
Type A : Type A encephalopathy occurs only in a person without pre-existing liver disease experiencing rapid deterioration liver function causing acute liver failure. Causes of hepatic encephaloencephalopathy syndrome type A are due to acetaminophen overdose, heavy alcohol consumption, hepatitis, Wilson disease Type B: Type B hepatic encephalopathy is caused by a portosystemic shunt which is an occlusion. between the portal vein and the vena cava of the collateral circulation or to reduce portal pressure should surgically create a portal-aortic shunt. Therefore, a large flow of blood from the digestive system directly into the circulatory system bypassing the liver is the main mechanism of disease. The two main causes of this condition are congenital and traumatic. Type C: Cirrhotic scarring is the cause of type C hepatic encephalopathy. Cirrhosis develops in late-stage liver disease, where the liver is less able to remove toxins from the blood and perform other functions.
