Neurological Symptoms of Wilson's Disease: What to Do When First-Line Therapy Has Not Worked

Clinical Scenario

This protocol applies to patients with neurological symptoms of Wilson's disease in whom the initial management strategy — reducing chelator doses, slowing dose escalation, and discontinuing dopamine receptor antagonists — did not achieve the expected therapeutic goals.

First-Line Goals That Were Not Reached

The first-line approach aimed at resolving paradoxical neurological worsening and achieving progressive improvement in neurological symptoms with a decrease or normalisation of the UWDRS score. Failure to reach these endpoints is the trigger for escalation to this next protocol step.

Next Step: Treatment Switch

This protocol involves switching the Wilson's disease treatment regimen. A change in treatment class is central to the approach, with second-line options available. The complete switching algorithm — which agents, in what order, and under what conditions — is available in the full protocol.

Treatment Goals

The target is progressive improvement of neurological symptoms, with decrease or normalisation of the UWDRS score as the primary measurable endpoint of treatment response.

Either zinc or chelators should be used in patients with a neurological presentation (LoE 2, strong recommendation, consensus).
Consequently, zinc or trientine may also be employed as second-line therapy for patients experiencing neurological deterioration despite first-line treatment.
If ineffective, the recommendation is to consider switching WD treatment (between chelators and from chelators to zinc), despite the absence of clear evidence from head-to-head treatment studies comparing the effects of D-penicillamine, trientine, and zinc in patients with neurological symptoms.
Neurological response to chelators may be delayed and is defined by the progressive disappearance or attenuation of symptoms and the decrease or normalisation of the UWDRS score.
