Conditions That Cause Secondary Myoclonus

Kidney Or Liver Failure

Secondary myoclonus can be caused by kidney or liver failure. Kidney failure is the final stage of kidney disease. When the kidneys have stopped working well enough to provide filtration, patients need to undergo dialysis or have a kidney transplant. When kidneys are starting to fail, patients might experience itching, general unwellness, unusual changes in urination, trouble sleeping or catching their breath, and muscle cramps. Sudden kidney failure might cause back and abdominal pain, fever, diarrhea, nosebleeds, rashes, and vomiting. Liver failure occurs when a large portion of the liver has become damaged beyond repair, causing the liver to be unable to function. When the liver fails over time, it's usually caused by conditions like malnutrition, hemochromatosis, cirrhosis, long-term consumption of alcohol, hepatitis B, or hepatitis C. Acute liver failure may occur rapidly because of an acetaminophen overdose, certain viruses, reactions to herbal and prescription medications, and ingestion of poisonous mushrooms.
