With aging it may seem normal to experience a loss in brain function, but often there are many contributing factors aside from age that takes a toll on brain function. Brain damage and dementia are just some other factors which can contribute to a loss in brain function. Another factor that diminishes brain function is a build-up of toxins in the blood.
Hepatic encephalopathy (HE) is a condition where the liver cannot remove toxins found in the blood. It results in a loss of brain function, and can lead to liver failure. The cause of this neuropsychiatric syndrome is a metabolic abnormalities. The liver is unable to remove and break down toxins found in blood either because the liver is damaged or blood does not circulate properly in the liver.
Often, if liver health improves, hepatic encephalopathy may be reversed. This can be done by treating the liver condition or increasing blood flow. Consequences of prolonged HE can result in a coma or even be fatal.
There are three main types of hepatic encephalopathy: Acute, chronic and chronic cerebral degeneration and myelopathy.
Acute encephalopathy: Rapidly progresses over a short time span. This is a complication of acute liver disease and is a sign of terminal liver failure. It is commonly found in patients who have acute fulminant viral hepatitis, toxic hepatitis and Reye’s syndrome. (Reye’s syndrome causes swelling of the liver and the brain.)
Chronic encephalopathy: Occurs multiple times and requires long-term treatment to minimize and prevent symptoms during intervening periods. Cirrhosis patients who have extensive portal collateral circulation and/or shunts typically experience this type of HE. In their case, patients have redundant circulation to their organs, meaning the blood can travel in different pathways to the same spot. In between episodes, chronic HE may be mild and symptoms may not be noticeable. Chronic HE is a sign of deterioration caused by cirrhosis, a liver disease resulting from alcoholism and hepatitis.
Chronic cerebral degeneration and myelopathy: Possible permanent neurological abnormalities that don’t respond well to treatment. It can affect a person’s ability to walk or stay balanced. It is quite rare. Tremors may be present similar to that of Parkinson’s disease.
Stage 1: Symptoms in this stage affect sleep patterns and may include anxiety, depression and restlessness.
Stage 2: Personality changes can occur in stage two of symptoms. The ability to complete mental tasks is impaired and disorientation occurs.
Stage 3: Behavior becomes bizarre, aggression and rage are present, speech becomes harder to understand and there is a sense of paranoia.
Stage 4: Coma may occur and patient becomes unresponsive to pain stimuli.
The livers main role is to filter out toxins from the body. These toxins could be introduced by environmental factors, diet and even the medications we take. When the liver is healthy, it can filter in these toxins without problems. But a sick and damaged liver cannot complete this function, which results in a build-up.
Risks of hepatic encephalopathy
To avoid HE, people should take care to maintain a healthy liver. Avoid used needles, minimize alcohol intake and maintain a healthy weight to protect your liver. There are other triggers as well that can increase one’s risk of developing HE, they include:
Symptoms of hepatic encephalopathy
Early Stage symptoms of HE
These symptoms can be seen in early stages of HE, but as the illness progresses, so do the symptoms.
Severe symptoms of HE:
Depending on the severity of symptoms, patients with HE have trouble caring for themselves and often require the assistance of a care-giver.
By maximizing liver health, you can better treat and even prevent hepatic encephalopathy. One way of doing this is through nutrition and diet. Diet plays a large role on liver health as everything we consume passes through the liver. By eating to promote liver health, you can lower your risk of developing HE.
