copper deficiency myelopathy

Copper deficiency myelopathy (CDM) can be effectively treated with copper supplementation.

• Oral copper supplementation, typically in the form of copper sulfate or cupric chloride, is a common treatment approach [8][9].
• The recommended dosage for oral copper supplementation ranges from 1.5 to 3 mg/day [8].
• In some cases, intravenous copper administration may be necessary, especially if the patient has severe anemia or neutropenia [4][6].

Prompt recognition and treatment of CDM are crucial in preventing significant neurological damage and improving outcomes.

• Early treatment with copper can lead to neurological improvement or stabilization in most cases [14].
• Treatment should be initiated promptly, ideally within a few days of diagnosis, to prevent further progression of the condition [6].

It is essential to note that copper deficiency myelopathy closely mimics subacute combined degeneration due to vitamin B12 deficiency, and patients may be given vitamin B12 despite normal serum levels. Therefore, it is crucial to rule out other causes of myelopathy before initiating treatment.

• Serum copper levels should be estimated as part of the work-up in patients with a myelopathy or suspected CDM [7].

Overall, copper supplementation is a key component of treating copper deficiency myelopathy, and prompt recognition and initiation of treatment are essential for optimal outcomes.

Differential Diagnosis of Copper Deficiency Myelopathy

Copper deficiency myelopathy (CDM) can be challenging to diagnose due to its similarity in presentation with other neurological conditions. The differential diagnosis for CDM includes:

• Subacute combined degeneration (SCD): A condition caused by vitamin B12 deficiency, which presents with similar symptoms to CDM.
• Folate deficiency: Another nutritional deficiency that can cause myelopathy and is often considered in the differential diagnosis of CDM.
• Vitamin B12 deficiency: A common cause of neurological symptoms, including myelopathy, which can be mistaken for CDM.
• Drug toxicity: Certain medications, such as those used to treat cancer or autoimmune disorders, can cause myelopathy and are part of the differential diagnosis for CDM.
• Infection: Infections, such as HIV, can cause neurological symptoms, including myelopathy, which may be mistaken for CDM.
• Autoimmunity: Autoimmune disorders, such as multiple sclerosis, can present with similar symptoms to CDM.

Key Factors in the Differential Diagnosis of CDM

The differential diagnosis of CDM requires a thorough analysis of the patient's history, physical examination, and laboratory results. Key factors that may help distinguish CDM from other conditions include:

• History of gastrointestinal surgery: Patients with CDM often have a history of gastric surgery or other conditions that affect copper absorption.
• Zinc overload: Elevated zinc levels can contribute to copper deficiency and are often seen in patients with CDM.
• Malabsorption: Malabsorption syndromes, such as celiac disease, can lead to copper deficiency and are part of the differential diagnosis for CDM.
