# Symptoms and phases of Wilson's disease
Wilson's disease leads to a buildup of copper in the body, particularly in the brain, liver, and eyes. This causes symptoms that depend heavily on which organs are affected and how severe the damage is. The course of the disease is highly individual: some people experience primarily liver problems, others primarily neurological symptoms. Below we describe the different phases and how they may present.
Phase 1: Asymptomatic (copper accumulation without symptoms)
In this phase, copper accumulates in the body, but this has no noticeable effects for the patient yet. Often the disease is only discovered in this phase because a family member who already has symptoms is diagnosed — after which other family members are screened.
**Symptoms:**
- No symptoms; the person feels completely healthy
- However, abnormalities may already be found on examination (for example, elevated copper levels in blood or urine, slightly lowered ceruloplasmin levels)
**What this means for daily life: **
Nothing changes in daily functioning. However, it is important that screened family members are checked regularly, as the disease can progress to the next phase at any time.
**Figures about this phase: **
When this phase begins and how long it lasts depends heavily on genetic factors and environmental conditions. No standard data are known about the median duration of this asymptomatic period at the population level. Individual differences are very large.

Phase 2: Liver disease (without or with mild neurological symptoms)
This is often the first phase in which symptoms appear. The liver is damaged by copper accumulation. The extent of damage varies greatly: some develop only mild inflammation, others develop severe cirrhosis.
**Complaints in this stage:**
- **Most common:** fatigue and malaise
- Yellowing of skin and whites of eyes (jaundice)
- Abdominal pain or discomfort in the upper right side of the abdomen
- Nausea and loss of appetite
- Weight loss
- Dark urine and pale stools
- Abdominal bloating (ascites) with more severe damage
- In some cases: mild concentration problems or mood changes (early sign of liver inflammation)
**What this means for daily life: **
Fatigue can make it difficult to work full-time or perform household tasks. Eating problems can lead to malnutrition. With severe liver damage, abdominal fluid can make movement difficult. Many patients feel unwell and cannot maintain social activities.
**Figures about this phase: **
Data on median survival without treatment in patients with symptomatic liver disease are scarce and strongly dependent on the degree of cirrhosis. In general, treatment at an early stage has much better outcomes. Individual prognosis depends on many factors that differ from person to person.

Phase 3: Neurological Wilson (with symptoms from the nervous system)
This is the most severe form. Copper damages different parts of the brain, leading to serious movement and behavioral disorders. This phase can develop suddenly or gradually from the liver disease.
**Complaints in this stage:**
*Movement disorders (most common):*
- Tremor (shaking), especially visible when hands are extended or during fine movements
- Rigidity: muscles feel stiff and resistant
- Slowness of movement (bradykinesia)
- Difficulty initiating movements
- Unsteady gait and balance problems
- Dysarthria: unclear or nasal speech
- Dysphagia: difficulty swallowing, risk of aspiration
*Behavioral disorders and cognitive symptoms:*
- Sudden mood changes or aggression
- Depression
- Anxiety disorders
- Obsessive-compulsive behavior
- Behavioral changes that resemble a personality change
- Concentration problems and memory difficulties
- Psychotic symptoms (very rare but possible)
*Eye symptoms:*
- Kayser-Fleischer ring: gold-green discoloration on the inside of the cornea (only visible with special examination, but a sign of serious disease)
*Other neurological symptoms:*
- Muscle cramps
- Seizures (rare)
- Migraine-like headaches
**What this means for daily life: **
This is very burdensome. The combination of movement problems and behavioral changes makes independent functioning difficult. Work is usually no longer possible. Many patients need help with self-care, as washing, dressing and eating are impaired. Speech problems make communication frustrating. Behavioral changes can put a severe strain on relationships, as loved ones sometimes do not recognize the person.
**Figures about this phase: **
The neurological form of Wilson disease is serious, but with modern treatment many symptoms can stabilize or even improve. Without treatment, the prognosis is very poor. Reliable population figures on survival and disease progression are scarce; much depends on how quickly the diagnosis is made and how well the patient responds to copper-chelating agents. Individual differences are very large.

Phase 4: Fulminant liver disease (acute, life-threatening liver failure)
This is a rare but very acute and life-threatening form. The liver suddenly fails.
**Complaints in this stage:**
- Very rapid increase in jaundice (icterus)
- Severe anemia
- Coagulation disorders (bleeding tendency)
- Acute neurological symptoms (confusion, disorientation, coma)
- Kidney failure
- Hepatic encephalopathy: confusion and drowsiness up to and including coma
**What this means for daily life: **
This is a medical emergency. Patients are no longer independent and require intensive hospital care. This may be needed very quickly after symptom onset (sometimes within days).
**Figures about this phase: **
The fulminant form is rare (approximately 3-5% of all presenting cases), but without liver transplantation mortality is very high (without transplantation: death within weeks to months). This is a directly life-threatening condition.
---
Phase 5: Recovery and stabilization under treatment
With early diagnosis and consistent treatment, patients can improve considerably, even after severe symptoms.
**What changes:**
- Tremor and other movement disorders gradually decrease, sometimes over weeks to months
- Mood and behavioral changes stabilize and improve
- Liver enzymes normalize
- Energy and appetite return
- Speech and swallowing improve
**What this means for daily life: **
Many patients can return to regular activities, although this depends on the severity of previous damage. Some can resume work, others have lasting limitations. Physical rehabilitation may be necessary. Crucial condition: consistent lifelong treatment and regular check-ups.
**Figures about this phase: **
With adequate treatment: the earlier the diagnosis and the sooner treatment starts, the better the recovery. Many patients can function well for decades as long as they adhere to their treatment. Survival rates for treated Wilson disease patients are much better, but exact figures vary greatly depending on when diagnosis is made and the severity of the original condition.

Likelihood of transition to next phase without treatment
Without treatment, disease progression gradually worsens. However, this can happen faster or more slowly. Some progress from asymptomatic directly to severe liver disease or neurological symptoms, others have mild symptoms for years. This is very unpredictable at the individual level.

Why contact your doctor?
Contact your doctor or go to the emergency department if:
- You suddenly become severely jaundiced, especially if it progresses rapidly
- You become confused, have hallucinations or your behavior changes suddenly significantly
- You bleed from your stomach (blood in vomit or black, tarry stools) — this can occur in advanced liver disease
- You develop chronic tremor or spasticity (stiff muscles) that rapidly worsens
- You develop double vision or cannot control your eye properly (very rare but can be an acute neurological sign)
- You rapidly develop breathing problems
- You have abdominal pain that does not go away
Even if you have been diagnosed with Wilson disease and you notice that your symptoms are changing despite treatment, contacting your doctor is important.
