Bioavailable Trace Metals in Neurological Diseases

Area of Science:

• Neurology
• Hepatology
• Pharmacology

Background:

• Wilson's disease requires lifelong medical management using chelators or zinc salts.
• Treatment is divided into initial de-coppering and long-term maintenance phases.
• Optimal therapeutic strategies and adherence remain significant challenges.

Purpose of the Study:

• To review current medical and surgical treatment options for Wilson's disease.
• To discuss the management of initial and maintenance phases of therapy.
• To explore novel therapeutic concepts for neurodegenerative conditions involving iron dysregulation.

Main Methods:

• Review of existing literature on Wilson's disease treatment.
• Discussion of pharmacological approaches including chelators and zinc.
• Consideration of liver transplantation indications.
• Exploration of emerging iron chelation therapies for neurodegeneration.

Main Results:

• D-penicillamine and trientine are primary chelators; zinc salts offer an alternative.
• Dosing adjustments based on copper levels are crucial during the initial phase.
• Liver transplantation is a critical option for acute liver failure and decompensated cirrhosis.
• Maintaining lifelong adherence to therapy is a key challenge in the maintenance phase.

Conclusions:

• Current treatment paradigms for Wilson's disease require lifelong commitment.
• Individualized treatment adjustments and adherence strategies are essential for patient outcomes.
• Emerging iron chelation strategies may offer new hope for related neurodegenerative disorders.
