| The classic clinical syndrome for '''Pyridoxine deficiency''' (or '''B6 deficiency''') is a seborrheic dermatitis-like eruption, atrophic glossitis with ulceration, angular cheilitis, conjunctivitis, intertrigo, and neurologic symptoms of somnolence, confusion, and neuropathy.<ref>Andrews' Diseases of the Skin, 10th Edition, Elsevier.</ref>

| Vitamin B6 is a co-factor for glutamic acid decarboxylase, an enzyme that converts Glutamate to GABA. Therefore, the concurrent increase in the excitatory neurotransmitter, Glutamate, and decrease in inhibitory neurotransmitter, GABA, resultant from B6 deficiency, may manifest itself in the form of seizures.

| |
| ==Causes==
| |
| *Supporters of a debated medical condition known as [[Pyroluria]] believe it may be one potential cause of vitamin B6 deficiency.
| |
| *Another cause of vitamin B6 deficiency is the use of the tuberculostatic medication [[isoniazid]], and for this reason, it is recommended to supplement with vitamin B6 when using this drug.
| |
| *Grumpiness and irritability are also often symptomatic of a deficiency according to "Body, Mind, and the B Vitamins" by Ruth Adams and Frank Murray.
| |
| *A [[meta-analysis]] of three databases ([[MEDLINE]], [[EMBASE]], and [[Cochrane Library]]), including only [[double-blind]], randomized controlled trials, found that vitamin B6 has a significant effect compared to [[placebo]]s in treating [[morning sickness]], similar to that of [[ginger]].<ref>[http://www.medicalnewstoday.com/medicalnews.php?newsid=22469 Pregnancy Morning Sickness - Ginger as Effective as Vitamin B6 (open)] [http://www.greenjournal.org/cgi/content/abstract/105/4/849 Effectiveness and Safety of Ginger in the Treatment of Pregnancy-Induced Nausea and Vomiting (subscription)], Borrelli ''et al.'', ''Obstetrics & Gynecology'', 2005;105:849-856</ref>

| ===Diagnostic Testing for B6 Deficiency===
| |
| A positive diagnosis test for pyridoxine deficiency can be assertained by measuring [[erythrocyte]] levels of [[aspartate aminotransferase]] and transketolase in [[blood plasma|serum]].
