First episode of catatonia followed by a psychotic episode related to chronic nitrous oxide use: A case report
To the best of our knowledge, this is the first report describing a cascade of neurologic and psychiatric complications of chronic use of nitrous oxide. Hyperhomocysteinemia caused by nitrous oxide consumption could explain the occurrence of such events. Homocysteine, methylmalonic acid, and active vitamin B12 are key biomarkers to determine the involvement of nitrous oxide in psychiatric symptoms.
