Acetazolamide is a carbonic anhydrase inhibitor that reduces neuronal hyperexcitability by decreasing intracellular and extracellular glutamate levels and modulating neuronal excitation-inhibition balance. By suppressing carbonic anhydrase enzymes, it alters neural signaling and may help mitigate the hyperactive visual cortex and sensory processing abnormalities associated with Visual Snow Syndrome. Its potential therapeutic effect involves reducing neurological hyperactivity and stabilizing aberrant neural network functioning.
