Symptoms of toxic copper levels include:īoth epilepsy and heart failure are also risk factors for asterixis. It’s present at birth but may not become apparent until adulthood. This is a rare, genetic disorder.Įxperts estimate about 1 in 30,000 people have Wilson’s disease. If left untreated and allowed to build up, copper can damage the brain. In Wilson’s disease, the liver doesn’t adequately process the mineral copper. The kidneys and their ability to do their job can be damaged by conditions like: If too many of these toxins are allowed to build up, they can alter brain function and lead to asterixis. Like the liver, the kidneys also remove toxic materials from the blood. This can happen because of a blood clot blocking an artery or because of a narrowing of the arteries due to things like smoking or high blood pressure. This includes: StrokeĪ stroke occurs when blood flow to a part of the brain is restricted. Pretty much anything that affects brain function can lead to asterixis. When the heart doesn’t pump enough oxygen throughout the body, the brain is affected. Certain medications, such as anticonvulsants (used to treat epilepsy) and barbiturates (used for sedation), can affect brain responses. This occurs when too much or too little of certain vitamins or minerals, such as ammonia, cross the blood-brain barrier, causing neurological misfirings. A complication of liver and kidney disease is metabolic encephalopathy. Consequently, they can build up in the blood and enter the brain, where they disrupt brain function. ![]() But when the liver is impaired for any reason, it may not remove toxins efficiently. The liver’s main function is to filter toxins from the body. Some types of encephalopathy that can result in asterixis are: Researchers suspect there may be certain triggers, which include encephalopathies.Įncephalopathies are disorders that affect brain function. Why that malfunction occurs isn’t entirely known. The disorder is thought to be caused by a malfunction in the part of the brain that controls muscle movement and posture. The condition was first recognized nearly 80 years ago, but a lot still remains unknown about it. ![]()
