why does flapping tremor occur?
Asterixis is a neurological disorder that causes a person to lose motor control of certain areas of the body. The flapping is said to resemble a bird’s wings in flight. According to research, these wrist-hand “tremors” or “flapping” motions are most likely to occur when the arms are outstretched and wrists are flexed.

What is the treatment for end stage liver disease?
Hepatic encephalopathy is treated by cleansing the bowel with lactulose-a laxative given orally or in enemas. Antibiotics are added to the treatment if necessary.

Abstract. Asterixis is a type of negative myoclonus characterized by irregular lapses of posture of various body parts. It is an uncommon but important sign in clinical neurology. Initially described as a “liver flap,” its utility encompasses a galaxy of neurological and nonneurological situations.
Is hepatic encephalopathy reversible?
With treatment, hepatic encephalopathy is frequently reversible. In fact, complete recovery is possible, especially if the encephalopathy was triggered by a reversible cause. However, people with a chronic liver disorder are susceptible to future episodes of encephalopathy. Some require continuous treatment.

What is hepatorenal syndrome?
Hepatorenal syndrome (HRS) is a type of progressive kidney failure seen in people with severe liver damage, most often caused by cirrhosis. As the kidneys stop functioning, toxins begin to build up in the body. Eventually, this leads to liver failure. There are two forms of HRS.
Can high ammonia levels cause tremors?
The result is a larger than normal concentration of ammonia in the blood, a condition called hyperammonemia. When too much ammonia makes its way into the central nervous system, it can lead to tremors, seizures and, in extreme cases, can cause comas and even lead to death.
