Vitamin B6 (pyridoxine) may potentially ameliorate Visual Snow Syndrome symptoms by modulating neuronal excitability and neurotransmitter metabolism, particularly through its role as a cofactor for glutamate decarboxylase which converts glutamate to GABA. Its mechanism involves reducing neuronal hyperexcitability and potentially stabilizing cortical neuronal function, which could help mitigate the abnormal visual processing characteristic of the syndrome.
