Wilson disease

01

What it is

Changes in both copies of ATP7B impair the liver's ability to move excess copper into bile. Copper first accumulates in the liver and can later circulate to the brain, cornea, kidneys, blood cells, and other tissues. It is inherited in an autosomal-recessive pattern: parents are often healthy carriers, while each full sibling has a meaningful chance of being affected. Symptoms can begin in childhood or adulthood, and absence of symptoms does not exclude injury.

Symptoms and how it may present

Wilson disease can first appear as liver disease, neurological change, psychiatric symptoms, or a combination. Possible signs include fatigue, jaundice, abdominal swelling, easy bleeding, tremor, stiffness, poor coordination, changes in speech or handwriting, difficulty swallowing, depression, anxiety, impulsivity, or a decline in school or work performance. Some people feel well and are identified through family screening. A copper-colored ring at the edge of the cornea can support the diagnosis but is not present in everyone and requires a trained eye examination.

Causes and risk factors

Wilson disease is caused by inherited ATP7B variants, not by eating ordinary amounts of copper or by personal behavior. A confirmed diagnosis should trigger structured assessment of first-degree relatives, particularly siblings, before irreversible damage develops. The exact variant does not reliably predict age of onset or whether liver, neurological, or psychiatric features will dominate. Other liver conditions can coexist, so alcohol exposure, viral hepatitis, metabolic liver disease, and medicines still matter during evaluation.

Diagnosis and tests

Tests should answer a clinical question and be interpreted together with symptoms, examination, and history.

No single result diagnoses every case. Evaluation commonly combines liver tests, a blood count and clotting tests, serum ceruloplasmin, copper measurements in blood and a carefully collected 24-hour urine sample, and a slit-lamp eye examination. Genetic testing for ATP7B variants can confirm many cases and help screen relatives, but interpretation may be difficult when variants are uncertain. Liver imaging, brain MRI, or a liver biopsy with copper measurement may be useful in selected situations. Results must be interpreted together because inflammation, liver failure, pregnancy, supplements, and collection errors can alter individual tests.

05

Treatment options

The best option depends on severity, other conditions, likely benefit and harm, access, and personal priorities.

Treatment lowers toxic copper and then prevents it from building up again. Chelating medicines such as D-penicillamine or trientine increase copper removal, while zinc salts reduce intestinal copper absorption. The choice and sequence depend on symptoms, organ involvement, pregnancy, side effects, access, and clinician experience. Neurological symptoms can temporarily worsen when treatment begins, so dosing and follow-up need specialist supervision. Acute liver failure or advanced liver disease that does not respond may require liver transplantation. Treatment is lifelong; feeling better or obtaining a normal test is not a reason to stop it.

Daily life and supportive care

Food changes support medicine but do not replace it. During initial treatment, a clinician or dietitian may advise limiting very high-copper foods such as liver and certain shellfish, and checking copper in well water or supplements. Extreme restriction can make eating unnecessarily difficult, and food lists vary by portion and source. Tell the care team about vitamins, minerals, herbal products, antacids, and the timing of meals because zinc and chelators have specific administration instructions and interactions. Regular activity, mental-health support, physical or speech therapy, and school or workplace accommodations can help with neurological or functional effects.

07

Monitoring and follow-up

Follow trends that can change a decision rather than collecting measurements without a purpose.

Follow-up checks symptoms, neurological function, mental health, adherence, liver enzymes and synthetic function, blood counts, urine copper, and medicine-specific adverse effects. The intended copper target depends on treatment phase and method, so isolated results should not be interpreted without the complete regimen and collection quality. Clinicians may also reassess eyes, imaging, nutrition, pregnancy plans, and family screening. Unexpected results should prompt a check of dosing, timing, laboratory method, adherence, and competing illness before a major change.

08

Complications and long-term outlook

People diagnosed before advanced organ injury can often live well with reliable lifelong treatment. Liver tests and neurological symptoms may improve at different speeds, and established cirrhosis or disability may not fully reverse. Stopping medicine can cause rapid, sometimes life-threatening worsening even after years of stability. Long-term care therefore includes practical work on medication supply, transitions between clinicians, pregnancy, travel, mental health, rehabilitation, education or employment, and a written plan for missed doses or illness.

09

When to seek urgent help

Untreated copper accumulation can cause cirrhosis, liver failure, movement disorders, swallowing problems, injury, or major psychiatric change. Seek urgent assessment for new jaundice, vomiting blood, black stools, marked abdominal swelling, confusion, severe sleepiness, sudden neurological decline, inability to swallow safely, or thoughts of self-harm. Families should know the emergency plan and medication list. A new symptom is not automatically Wilson disease, so clinicians should also assess infection, medicine effects, injury, and other causes rather than simply increasing treatment.

Questions to discuss with a care team

A guideline describes what tends to help groups of people, but it cannot decide what matters most in one person’s life. Revisit the plan when symptoms, function, other illnesses, pregnancy plans, medicine access, side effects, or personal priorities change. Ask for plain-language reasoning and say directly when cost, time, transport, caregiving, or treatment complexity makes a recommendation unrealistic.

• What evidence supports this diagnosis, and is there another condition we still need to rule out?
• What is the treatment goal, and how do the main options differ in benefit, harm, burden, and cost?
• What should be monitored, how often, and what result would change the plan?
• Which symptoms require a routine appointment, urgent assessment, or emergency care?
