A. The clinical picture is dominated by three (or more) of the following symptoms:

  1. Stupor (i.e., no psychomotor activity; not actively relating to environment).
  2. Catalepsy (i.e., passive induction of a posture held against gravity).
  3. Waxy flexibility (i.e., slight, even resistance to positioning by examiner).
  4. Mutism (i.e., no, or very little, verbal response [exclude if known aphasia]).
  5. Negativism (i.e., opposition or no response to instructions or external stimuli).
  6. Posturing (i.e., spontaneous and active maintenance of a posture against gravity).
  7. Mannerism (i.e., odd, circumstantial caricature of normal actions).
  8. Stereotypy (i.e., repetitive, abnormally frequent, non-goal-directed movements).
  9. Agitation, not influenced by external stimuli.
  10. Grimacing.
  11. Echolalia (i.e., mimicking another's speech).
  12. Echopraxia (i.e., mimicking another's movements).

Note: Indicate the name of the associated mental disorder when recording the name of the condition (i.e., catatonia associated with major depressive disorder). Record first the associated mental disorder (e.g., neurodevelopmental disorder, brief psychotic disorder, schizophreniform disorder, schizophrenia, schizoaffective disorder, bipolar disorder, major depressive disorder, or other mental disorder) (e.g., schizoaffective disorder, depressive type; catatonia associated with schizoaffective disorder).
