Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
Recurrent brief depression (RBD) defines a mental disorder characterized by intermittent depressive episodes, not related to menstrual cycles in women, occurring between approximately 6–12 times per year, over at least one year or more fulfilling the diagnostic criteria for major depressive episodes (DSM-IV and ICD-10) except for duration in which RBD is less than 14 days (typically 5–7 ...
Latent iron deficiency (LID), also called iron-deficient erythropoiesis, [1] is a medical condition in which there is evidence of iron deficiency without anemia (normal hemoglobin level). [2] It is important to assess this condition because individuals with latent iron deficiency may develop iron-deficiency anemia.
Vitamin B 6: pyridoxal phosphate (PLP), the active form of B 6, is a cofactor in the dopamine serotonin pathway, a deficiency in vitamin B 6 may cause depressive symptoms. [ 98 ] Folate (vitamin B 9 ) – Vitamin B 12 cobalamin: Low blood plasma and particularly red cell folate and diminished levels of vitamin B 12 have been found in patients ...
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
Iron-deficiency anemia is the most common type of anemia overall and it has many causes. RBCs often appear hypochromic (paler than usual) and microcytic (smaller than usual) when viewed with a microscope. Iron-deficiency anemia is due to insufficient dietary intake or absorption of iron to meet the body's needs. Infants, toddlers, and pregnant ...
Myeloperoxidase deficiency is a disorder featuring lack in either the quantity or the function of myeloperoxidase–an iron-containing protein expressed primarily in neutrophil granules. [ 1 ] [ 2 ] [ 3 ] There are two types of myeloperoxidase deficiency: primary/inherited and secondary/acquired. [ 4 ]
A 2012 cross-sectional study found an association between zinc deficiency and depressive symptoms among women, but not men, [72] and a 2013 meta-analysis of 17 observational studies found that blood zinc concentrations were lower in depressed subjects than in control subjects. [73]
