Final answer:
The common causes of hepatic encephalopathy include acute liver failure, chronic liver failure, and hepatitis.
Step-by-step explanation:
Hepatic encephalopathy is a reversible neuropsychiatric abnormality that occurs in liver failure, both chronic (such as cirrhosis) and acute. There are several common causes of hepatic encephalopathy. These include:
- Acute liver failure, which is characterized by the development of confusion, stupor, and coma within four weeks of the first symptoms of a liver problem.
- Chronic liver failure, which can be caused by excessive alcohol intake, hepatitis B or C, autoimmune diseases, and metabolic causes.
- Hepatitis, which is inflammation of the liver. Viral infections, such as hepatitis A, hepatitis B, and hepatitis C, can cause hepatic encephalopathy.
