a condition in which brain function is impaired by the presence of toxic substances, absorbed from the colon, which are normally removed or detoxified by the liver. It occurs when the liver is severely damaged (as in cirrhosis) or bypassed. Symptoms include drowsiness, confusion, difficulty in performing tasks (e.g. writing), and coma. Treatment consists of stopping protein intake and administering antibiotics (to prevent bacterial production of toxins) and enemas and cathartics (to remove colonic toxins).
