 Wilson's disease is an inherited disorder of copper metabolism characterized by excessive copper accumulation in the body. Symptoms can range from mild to severe, depending on the severity of the condition. Early diagnosis and treatment are essential to avoiding serious complications. Serum biomarkers of copper metabolism and liver injury have been identified, but no reliable markers of CNS involvement exist yet. Research into these markers is ongoing, and may provide valuable insight into the progression of Wilson's disease and its effects on the brain.
