Dopamine agents for hepatic encephalopathy.

Patients with hepatic encephalopathy may present with extrapyramidal symptoms and changes in basal ganglia. These changes are similar to those seen in patients with Parkinson's disease. Dopamine agents (such as bromocriptine and levodopa, used for patients with Parkinson's disease) have therefore been assessed as a potential treatment for patients with hepatic encephalopathy.
