About 28% of patients with liver cirrhosis develop encephalopathy during the course of the disease and within this percentage, 84% will develop MHE. Currently, chronic liver diseases are the third leading cause of death in Mexico. The high prevalence suggests that HE could become a public health problem, with the 2020 projected figures of 1.5 million people with cirrhosis, which represents approximately 400 000 to 500 000 people with probable encephalopathy.
