Zinc-Induced Copper Deficiency

Micronutrient Deficiency Syndrome: Zinc, Copper and Selenium

Nutrients are defined as not only having nutritive values of participating in the metabolism and building the structures of cells but also being safe for human body. Nutrients are divided into two types, macronutrient and micronutrient, according to the proportion of the human body. Commonly, micronutrients include trace elements (trace mineral) and vitamins (complex organic molecules). It is d...

Zinc containing dental fixative causing copper deficiency myelopathy.

A 62-year-old male, previously well, was referred to neurology clinic following 6 months history of worsening lower limbs instability, paraesthesia, pain and weakness rendering him housebound. Examination revealed upper motor neuron pattern of weakness of the lower limbs and loss of proprioception. Serum analysis revealed reduced caeruloplasmin and copper levels with raised zinc. Spinal imaging...

Zinc-induced copper deficiency: a report of three cases initially recognized on bone marrow examination.

Copper deficiency is a rare cause of sideroblastic anemia and neutropenia that often is not suspected clinically. The morphologic findings in bone marrow, while not pathognomonic, are sufficiently characteristic to suggest the diagnosis, leading to further testing to establish the correct diagnosis. Excess zinc ingestion is among the causes of copper deficiency. We present 3 cases of zinc-induc...

Incidence of zinc and copper deficiency in Japan.

Copper excess, zinc deficiency, and cognition loss in Alzheimer's disease.

In this special issue about biofactors causing cognitive impairment, we present evidence for and discuss two such biofactors. One is excess copper, causing neuronal toxicity. The other is zinc deficiency, causing neuronal damage. We present evidence that Alzheimer's disease (AD) has become an epidemic in developed, but not undeveloped, countries and that the epidemic is a new disease phenomenon...
