Folate deficiency, also known as vitamin B 9 deficiency, is a low level of folate and derivatives in the body. [1] This may result in megaloblastic anemia in which red blood cells become abnormally large, and folate deficiency anemia is the term given for this medical condition. [3] Signs of folate deficiency are often subtle. [4]
Folate (Vitamin B 9) deficiency: Symptoms may include feeling tired, heart palpitations, shortness of breath, feeling faint, open sores on the tongue, loss of appetite, changes in the color of the skin or hair, irritability, and behavioral changes. [32] In adults, anemia (macrocytic, megaloblastic anemia) can be a sign of advanced folate ...
A complex interaction occurs between folic acid, vitamin B 12, and iron. A deficiency of folic acid or vitamin B 12 may mask the deficiency of iron; so when taken as dietary supplements, the three need to be in balance. [73] [74] [75]
Folate deficiency (vitamin B9 deficiency) can cause glossitis, along with macrocytic anemia, thrombocytopenia, leukopenia, diarrhea, fatigue and possibly neurological signs. [7] Apart from pernicious anemia discussed above, any other cause of vitamin B12 deficiency can cause glossitis, which tends to be painful, smooth and shiny.
In children with cerebral folate deficiency, the cerebrospinal fluid shows low levels of 5MTHF, and a loss of white matter in the brain (leukodystrophy) may occur. As a result of the decreased levels of 5MTHF, the child experiences low levels of Vitamin B folate. [12] There is inability for the 5MTHF to be transported across the blood-brain ...
[56] [57] Low levels of serum vitamin B 12 may be caused by other factors than B 12 deficiency, such as folate deficiency, pregnancy, oral contraceptive use, haptocorrin deficiency, and myeloma. [57] High serum levels may caused by supplementing with vitamin B 12, present of antibodies to intrinsic factor, or due to underlying condition. [56]
[104] [105] As for the classic deficiency of vitamin B12, it would affect up to 40% of the population, its prevalence has not yet been studied in autism spectrum disorders. Vitamin B12 deficiency is one of the most serious. [106] Vitamin B9 (folic acid): Studies have been conducted regarding folic acid supplementation in autism in children ...
Vitamin B 12 deficiency prevents the 5-methyltetrahydrofolate (5-MTHF) form of folate from being converted into THF due to the "methyl trap". [18] This disrupts the folate pathway and leads to an increase in homocysteine which damages cells (for example, damage to endothelial cells can result in increased risk of thrombosis).
