    en.wikipedia.org/wiki/Organophosphate-induced...

    The exact cause of the syndrome is unknown, although it has been associated with inhibition of patatin-like phospholipase domain-containing protein 6 (PNPLA6, aka neuropathy target esterase). There is no specific treatment, and recovery is usually incomplete, affecting only sensory nervous system , while motor neuropathy persists.

  4. Sensory neuronopathy - Wikipedia

    en.wikipedia.org/wiki/Sensory_neuronopathy

    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.

  7. Toxic and nutritional optic neuropathy - Wikipedia

    en.wikipedia.org/wiki/Toxic_and_nutritional...

    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 ...

  8. Alcoholic polyneuropathy - Wikipedia

    en.wikipedia.org/wiki/Alcoholic_polyneuropathy

    However, there is ongoing debate over the active mechanisms, [6] [7] including whether the main cause is the direct toxic effect of alcohol itself or whether the disease is a result of alcoholism-related malnutrition. [1] A 2019 metastudy found that the relationship between ethanol toxicity and neuropathy remained unproven. [8]

  9. Neuritis - Wikipedia

    en.wikipedia.org/wiki/Neuritis

    Deficiency of vitamin B 12 causes subacute combined degeneration, a disease classically associated with a central demyelinating process; however, it also presents with a painful peripheral neuropathy. Treatment of vitamin deficiencies focuses around repletion of specific deficiencies, recovery is often prolonged and some of the damage is often ...
