  • Title: Chronic 'speech catatonia' with constant logorrhea, verbigeration and echolalia successfully treated with lorazepam: a case report.
    Author: Lee JW.
    Journal: Psychiatry Clin Neurosci; 2004 Dec; 58(6):666-8. PubMed ID: 15601393.
    Abstract:
    Logorrhea, verbigeration and echolalia persisted unremittingly for 3 years, with occasional short periods of motoric excitement, in a patient with mild intellectual handicap suffering from chronic schizophrenia. The speech catatonic symptoms, previously refractory to various antipsychotics, responded promptly to lorazepam, a benzodiazepine with documented efficacy in the treatment of acute catatonia but not chronic catatonia. It is suggested that pathways in speech production were selectively involved in the genesis of the chronic speech catatonic syndrome, possibly a rare form of chronic catatonia not previously described.
