Nitrous oxide (N₂O), historically used as an anesthetic and more recently as a recreational drug, has been associated with neurological complications such as myeloneuropathy and thromboembolic events.

Most patients reported chronic N₂O use. Hyperhomocysteinemia was reported in nine patients.

However, it is still uncertain whether plasma HIF-1α can be a causal indicator for the relevant diseases.

Summary-level data for neurological disorder from genome-wide association studies (GWAS) were identified as outcomes.
