The relationship between the amount of vitamin B 6 consumed and the serum levels of those who consume it varies between individuals. [52] Some people may have high serum concentrations without neuropathy symptoms. [13] [53] [54] It is not known if inhalation of vitamin B 6 while, for example, working with animal feed containing vitamin B 6 is ...
Vitamin B6 is thought to lead to neuropathy due to its cytoskeletal and microtubule toxicity leading to nerve cell loss with prolonged overdosing. [ 2 ] Possible infectious causes of sensory neuronopathy include HIV (in which lymphocyte infiltrates have been observed in the dorsal root ganglion), Human T-lymphotropic virus 1 , Epstein-Barr ...
A common side effect is numbness in the hands and feet, also known as peripheral neuropathy. [18] Co-treatment with vitamin B 6 alleviates the numbness. [19] Overconsumption of seeds from Ginkgo biloba can deplete vitamin B 6, because the ginkgotoxin is an anti-vitamin (vitamin antagonist). Symptoms include vomiting and generalized convulsions.
The predominant cause of nutritional optic neuropathy is thought to be deficiency of B-complex vitamins, particularly thiamine [2] (vitamin B 1), cyanocobalamin (vitamin B 12) and recently copper. [3] Deficiency of pyridoxine (vitamin B 6), niacin (vitamin B 3), riboflavin (vitamin B 2), and/or folic acid also seems to play a role. Those ...
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Hypervitaminosis is a condition of abnormally high storage levels of vitamins, which can lead to various symptoms as over excitement, irritability, or even toxicity. Specific medical names of the different conditions are derived from the given vitamin involved: an excess of vitamin A, for example, is called hypervitaminosis A.

In general, lower levels of enzyme activity correlate with more severe symptoms. The decrease in ALP activity leads to an increase in pyridoxal 5’-phosphate (PLP), which is the major form of Vitamin B6, in the blood, although tissue levels of Vitamin B6 may be unremarkable [ 30 ] and correlates with disease severity.
