Comparison of Ketamine-Induced Thought Disorder in Healthy Volunteers and Thought Disorder in Schizophrenia
Abstract
OBJECTIVE: This study sought to determine whether thought disorder induced in healthy volunteers by the N-methyl-D-aspartic acid (NMDA) receptor antagonist ketamine resembles the thought disorder found in patients with schizophrenia. METHOD: The Scale for the Assessment of Thought, Language, and Communication was used to assess thought disorder in healthy volunteers (N = 10) who received subanesthetic doses of ketamine and in a group of clinically stable inpatients with schizophrenia (N = 15) who did not receive ketamine. RESULTS: Mean scores on the Scale for the Assessment of Thought, Language, and Communication for patients with schizophrenia and healthy volunteers receiving ketamine did not differ significantly. Moreover, three of the four highest rated test items in both groups were the same. CONCLUSIONS: These data suggest that ketamine-induced thought disorder in healthy volunteers is not dissimilar to the thought disorder in patients with schizophrenia and provide support for the involvement of the NMDA receptor in a cardinal symptom of schizophrenia.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
