The earliest clinical manifestations of hepatic encephalopathy are personality changes and behavioral abnormalities, and with the progression of the disease, symptoms such as drowsiness, coma, and fluttering wing-like tremor may also appear. Hepatic encephalopathy is generally due to the ammonia metabolism disorder caused by liver cirrhosis, portal vein shunt, etc. Blood ammonia enters the brain through blood circulation, resulting in central nervous system dysfunction, and the patient firstly experiences personality and behavioral changes, such as agitation, anxiety, sleep reversal, forgetfulness, irritability, etc., but the symptoms are not obvious. With the gradual accumulation of ammonia in the body, the poisoning symptoms of the central system will be more serious, and the patient will experience coma, serious behavioral abnormalities such as urinating and defecating anywhere, deep coma, and disappearance of tendon reflexes. It is recommended that the patient go to the hospital in time for treatment under the guidance of a physician.
