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.
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.
- 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 placebos in treating morning sickness, similar to that of ginger.
