At least three out of twelve symptoms must be present for a diagnosis of catatonia. These symptoms include:

Stupor (oblivious inability to move or respond to stimuli), catalepsy (rigid body posture)
Mutism (little to no verbal communication)
Waxy flexibility (body remains in whatever position it is placed by another)
Negativism (lack of verbal response)
Posturing (holding a posture or position that goes against gravity)
Mannerisms (extreme or odd movements and mannerisms)
Stereotypy (frequent repetitive movements for no reason)
Agitation (for no reason), grimacing (distorted facial expressions)
Echolalia (repeating others’ words)
Echopraxia (repeating others’ movements).
Other common symptoms include rigidity and automatic obedience. When catatonia is associated with schizophrenia, stupor may continue for long periods of time as compared to schizophrenia associated with other psychiatric conditions, where there are likely to be long remissions.
