The findings, published in the American Journal of Neuroradiology, showed that cases of spinal cord damage caused by nitrous oxide have spiked significantly since the Covid-19 pandemic. However, the drug can interfere with the body’s ability to process vitamin B12, leading to a condition called subacute combined degeneration (SACD) of the spinal cord. Although most patients in the study improved after treatment, none made a full recovery, with all experiencing some degree of lasting neurological damage.
