CNS demyelination associated with copper deficiency and hyperzincemia

Area of Science:

• Neurology
• Metabolic Disorders
• Hematology

Background:

• Central nervous system (CNS) demyelination is a significant neurological condition.
• Acquired copper deficiency is typically associated with hematologic abnormalities.
• CNS demyelination has not been previously linked to acquired copper deficiency.

Observation:

• Two patients presented with idiopathic hypocupremia (low copper levels) and hyperzincemia (high zinc levels).
• Both patients exhibited hematologic changes consistent with copper deficiency.
• Extensive CNS demyelination was observed in both individuals.

Findings:

• Copper supplementation led to hematologic recovery in the patients.
• Neurological abnormalities stabilized following copper therapy, even after relapse.
• Serum zinc levels remained elevated throughout the study period.

Implications:

• This study identifies CNS demyelination as a potential, previously unrecognized manifestation of acquired copper deficiency.
• Highlights the complex interplay between copper and zinc metabolism in neurological health.
• Suggests that while copper repletion can address hematologic deficits, neurological recovery may be incomplete, necessitating further research into treatment strategies.
