When this ‘bypass’ of blood product occurs, and toxic blood is used throughout the system, the damage to the organs especially, begins almost immediately. Because the body is not capable of breaking down the ammonia level by itself, it (the ammonia) will begin to infiltrate into the system, eventually into the brain. This is when the symptoms may begin to appear.

Early Hepatic Encephalopathy Symptoms

With an excess of ammonia in the body, the central nervous system will try to incorporate it into circulation. When this happens, the individual will at first appear slightly disoriented; forgetting where they placed things, or what they were doing. The symptoms will resemble those of a patient in the early stages of dementia. Soon, they will forget what they were saying, unable to complete their sentences or what they were writing. Often, they will start to sound as if they have been drinking alcohol; slurring words, mumbling incoherently and stuttering. Motor control skills are compromised and simple tasks like holding a pen, typing, or using any type of tool that requires dexterity will become difficult, if not impossible.

Depending on the level of the ammonia, the patient may exhibit a slanted, or sideways, gait when they walk. Patients report feeling as though they are walking on a tilted surface, as one would experience in a ‘fun house’. Although this perception of slanted ground beneath their feet is totally perceived by their brain, the patient is not aware that they are walking strangely, or carrying their body in a strange position. If the condition is not quickly controlled, the patient may have to be confined to a wheelchair. This is for their own protection, as they are apt to fall while attempting to correct the perceived ground level. Shaking is also a very common side effect. Trembling hands and fingers, and the inability to hold the hand in a fixed position are typical.

Late Hepatic Encephalopathy Symptoms

Eventually, a total loss of all motor skills results and dexterity is lost. The patient will take on a jaundiced appearance, noticed first in the whites of the eyes. The skin tone will follow, fading into a pallid, yellowish tint. The lips are extremely dry and begin to peel. The mouth will be constantly dry and the tongue may swell, which contributes to the slurring. If an individual experiences any of these hepatic encephalopathy symptoms, it is recommended that a physician be consulted immediately.

Sequence of Liver failure symptoms

At the early stages, liver failure symptoms are similar to symptoms of many other common illnesses thus making it difficult to diagnose the condition. The symptoms at the stage are inclusive of nausea, loss of appetite, fatigue and diarrhea. At much advanced stages, the liver failure symptoms become more severe hence calling for immediate attention from specialists. Symptoms include jaundice, which is one of the major liver failure symptoms. It is a condition that results as a failure of the liver to produce bile juice properly. Jaundice is signified by the skin on the entire body and at times the white part of the eye turning pale yellow or orange. There are two types of jaundice commonly known; the yang and yin jaundice. Yang jaundice is characterized by thirst, palpitations, constipation abdominal distention yellowing of the tongue and the entire body color resembling fresh tangerine color. This type of jaundice is believed to result from excess dampness or moist heat. For the yin Jaundice, the skin, face and eyes of he sufferer turn yellow. Severe fever, nausea, loss of appetite, fatigue, loose stools, chest repression, breaking breath among others also form part of the liver failure symptoms.

Loss of appetite that results from digestion complications is yet another of the liver failure symptoms.  Lack of appetite will gradually result the sufferer loosing weight and poor metabolism of carbohydrates and proteins at its worst. Poor appetite can at times lead to anemia. Other symptoms that come along with loss of appetite include vomiting that at times may contain blood, diarrhea and nausea that makes the body of the sufferer generally weak.

Another liver failure symptom is the light color of the stool which can be either gray or pale. This color of the stool is as a result of bile pigments obstruction due to low secretion of the juice or bile duct blockage. The bile pigments obstruction mostly occurs due to scarring, stones or inflammation of the liver membranes.

Abdominal pain as one of the liver failure symptoms occur when the abdominal region beneath the ribs becomes extended due to hepatomegaly or ascites. At severe levels, this distention causes painful breathing due to the pressure build up on the diaphragm.

Excessive thirst and frequent urination are also some of the liver failure symptoms although they are common in other illnesses. Other liver failure symptoms include headaches, allergy, dizziness, stroke or coma, eye redness and itching, short-lived temper and regular irritation, depression and mood swings.

Basically, the severity of the liver failure condition determines the most expected liver failure symptoms. Medication of the liver failure is also depending on the stage or how severe the liver failure symptoms are.

Thus, the harm alcohol can manifest as hepatic encephalopathy, which may result in sleep disturbances, mood swings, changes in personality traits, anxiety and depression, cognitive disorders (i.e., cognitive) functions, for example, inability to concentrate, and well as problems with coordination of movements (as is often observed asterisks – spasmodic flapping tremor). In the most severe cases, patients may fall into a coma (hepatic coma), which is often lethal.

New brain scan technology allows scientists to analyze the activity of different brain regions in patients with liver disease caused by alcoholism and, therefore, to examine the development of hepatic encephalopathy. According to the results of relevant studies identified at least two toxic substances that provoke the development of hepatic encephalopathy – ammonia and manganese. The harm of alcohol in this case is applied as follows. Liver cells damaged by alcohol, produce excessive amounts of these harmful substances, which can then reach the brain and destroy brain cells.

Hepatic encephalopathy treatment Medical Procedures

To prevent the development of hepatic encephalopathy are commonly used following medical procedures:

Appointment of drugs that reduce ammonia levels in the blood, for example, L-ornithine, L-aspartate.

The use of various medical technologies, such as devices that support the functioning of the liver, also known as “artificial liver”, which contribute to cleaning the patient’s blood from toxic substances. Studies have shown that the use of devices of this type of ammonia concentration in the blood is greatly reduced, allowing partially reduce the effects of encephalopathy.

Liver transplantation – is widely used to treat patients with severe (final) stage of cirrhosis. According to medical statistics, a liver transplant using the latest medical technology leads to significant improvement in cognitive function in patients up to their full recovery and to reduce the concentration of manganese and ammonia in the blood to normal levels.

The appearance of signs of encephalopathy in patients with compensated liver failure with no apparent external cause (e.g., infections, inappropriate drugs) suggests the possibility of hidden gastrointestinal bleeding from esophageal varices, gastric ulcer, duodenal ulcer or intestinal tumors. In the absence of external signs of gastrointestinal bleeding first step in examination of the patient must be a rectal examination and fecal blood.

General principles of hepatic encephalopathy treatment are to reduce the load of the gastrointestinal tract in protein, normalization of disorders of water and electrolyte metabolism, need to avoid potentially dangerous drugs and the use of therapies that reduce the production of ammonia in the intestine and increase its excretion from the body.

In recent years has spread the use of drugs, correcting the alleged disorder neurotransmitter in the brain. These “heroic” measures such as cross-circulation and liver transplantation are rarely used. Usually they are used for acute and severe liver disease with culminant type of encephalopathy has completely healthy before the sick.

Reducing the load of the gastrointestinal tract with the help of proteins

Reducing the protein contents of the gastrointestinal tract is achieved by a temporary reduction in its amount in the food and the removal of suitable methods of blood from the stomach or colon (intestinal lavage, endoscope aspiration).

Treatment of venous bleeding, and other sources of bleeding provides options intubation bowel lavage and tamponade. In patients with mild encephalopathy should be reduced protein intake to 20-40 grams per day. With its moderate or more severe should be administered entirely protein-free diet.

Hepatic encephalopathy, otherwise known as portosystemic encephalopathy, is a disease that causes liver failure. Toxins that are usually filtered by the liver gradually build up in the bloodstream. Toxicity results from incomplete liver function and can lead to coma or even death if untreated. In some cases, treatment can be very effective and even reverse the disease.

Hepatic encephalopathy is treated according to severity. It may be necessary to provide intensive care for severe cases of the disease. A liver transplant may also be necessary to treat advanced hepatic encephalopathy. Mild forms of the disease can be treated with antibiotics and special care such as; changing the diet and treating other underlying diseases. When the disease is detected at an early stage it is more likely that it can be reversed.

Rifaximin is one of the newer antibiotics used in hepatic encephalopathy treatment. It reduces the amount of ammonia-producing bacteria in the body. Ammonia and other intestinal toxins are what cause hepatic encephalopathy and liver failure. Rifaximin has been efficient in many cases for the treatment of the disease. Studies have shown that Rifaximin has reduced the risk of hospitalization due to hepatic encephalopathy, and has been very effective with little or no side effects. It is possible that people taking Rifaximin will experience; lethargy, dizziness, nausea, gas, and headaches. Allergic reactions and more severe side effects have seldom been reported with the use of Rifaximin. Also, unlike other antibiotics, Rifaximin has a low probability of causing bacterial resistance.

People suffering from hepatic encephalopathy find it hard to live with the disease. It can cause a great deal of physical pain and emotional distress often leading to depression. Since Rifaximin was approved by the FDA in 2004, more people have been given hope of recovering from hepatic encephalopathy. It is currently one of the more effective forms of treatment for the disease and has immensely reduced hospitalization stays. It is usually favored as a first choice treatment for less severe forms of hepatic encephalopathy. Rifaximin has the ability to improve a person’s quality of life.

Hepatic encephalopathy is diagnosed with various tests including; blood tests, ultrasound screening, and biopsy of the liver. Most people suffering from a mild form of hepatic encephalopathy are not easily diagnosed. The symptoms may not be present or are not severe enough to be easily detected. People with a mild form of the disease may experience; confusion, poor memory, inability to sleep at night, sleepiness during the day, unexplained irritability, and balance incoordination. A more severe form of hepatic encephalopathy will manifest with more noticeable symptoms. These include; lethargy, increased state of confusion, behavioral changes, seizures, and coma. The general characteristics of liver failure may also be present. These symptoms include; jaundice (yellowing of the skin and the white part of the eyes), accumulation of fluid in the abdomen, fluid accumulation in the skin (especially the legs), and reflex abnormalities.

It is caused by accumulation in the bloodstream of toxic substances that are normally removed by the liver. The diagnosis of hepatic encephalopathy requires the presence of impaired liver function and the exclusion of an alternative explanation for the symptoms. Blood tests may assist in the diagnosis. Attacks are often precipitated by an intercurrent problem, such as infection or constipation.

Hepatic encephalopathy is reversible with treatment. This relies on suppressing the production of the toxic substances in the intestine and is most commonly done with the laxative lactulose or with non-absorbable antibiotics. In addition, the treatment of any underlying condition may improve the symptoms. In particular settings, such as acute liver failure, the onset of encephalopathy may indicate the need for a liver transplant.

Encephalopathy is the mandatory clinical feature for diagnosis of acute liver failure. Difficulties in the recognition of the early stages of encephalopathy and distinction from drug-induced and renal induced alterations of mental state do not detract from the value of this sign as the most powerful clinical indicator of the severity of liver disease. Once encephalopathy develops, the patient is at high risk for the development of cerebral edema and multi organ failure.

Hepatic encephalopathy may be triggered by; Dehydration, Eating too much protein, Electrolyte abnormalities and a decrease in potassium from vomiting, or from treatments such as paracentesis or taking diuretics, Bleeding from the intestines, stomach, or esophagus, Infections, Kidney problems, Low oxygen levels in the body, Shunt placement or complication, and surgery.
The causes of encephalopathy are both numerous and varied. Some examples of causes of encephalopathy include; infections, anoxia- lack of oxygen to the brain, alcohol consumption, liver failure, kidney failure, metabolic diseases, brain tumors, many types of toxic chemicals, alterations in pressure in the brain, and poor nutrition.

Despite the numerous and varied causes of encephalopathy, at least one symptom present in all cases is an altered mental state. The altered mental state may be subtle and develop slowly over years. For example, in hepatitis the decreased ability to draw simple designs, termed apraxia or be profoundly obvious and develop rapidly. Often, symptoms of altered mental status can present as inattentiveness, poor judgment, or poor coordination of movements.
Other symptoms that may occur are lethargy, dementia, seizures, tremors, muscle twitching, and coma. Often the severity and type of symptoms are related to the severity and cause of the brain disease or damage. For example, alcohol-induced liver damage can result in involuntary hand tremors, while severe anoxia may result in coma with no movement.

Therefore, Hepatic Encephalopathy is very dangerous, as it might cause death.
