Hyperammonemia induced gut microbiota dysbiosis and motor coordination disturbances in mice: new insight into gut‑brain axis involvement in hepatic encephalopathy.

Hepatic encephalopathy (HE) is a neuropsychiatric hepatic‑induced syndrome in which several factors are involved in promoting brain perturbations, with ammonia being the primary factor. Motor impairment, incoordination, and gut dysbiosis are some of the well‑known symptoms of HE. Nevertheless, the link between the direct effect of hyperammonemia and associated gut dysbiosis in the pathogenesis of HE is not well established.
